Seagate GoFlex Home single-disk network-attached storage – an example of an entry-level NAS

As you outgrow an existing network-attached storage device that isn’t upgradeable, you may think of buying a newer higher-capacity NAS.

The older NAS is a secondary network data storage

This is something I have done lately as I outgrew the Western Digital MyBook World Edition’s 1Tb capacity and received a 3Tb Seagate GoFlex Home NAS as a birthday gift. Here, I was able to move my “work” data and system backups to the GoFlex while running the My Book World Edition as a DLNA Media Server for my photos and music. I could run either of these units as part of shifting data between two computers or run the My Book also as a data store for drivers, anti-virus, service packs and similar computer-service needs.

Spreading data storage across multiple units

Here, you don’t need to get rid of the older NAS, but run it as a secondary unit. For example, you could simply move most of the data like backup data or work-in-progress data off the older unit to the newer unit and run the older unit as a media server or simple data drop-off point. This can come in handy if you have to shift user-created data from that old half-dead laptop to that shiny new fast laptop before you retire it, or keep a collection of drivers and service packs for when you have to install new computers.

Separating business and personal data

In some cases, you could move business data to the newer NAS and have personal data on the older unit so you can segment the units easily for tax or corporate reimbursement purposes.

Your children and their data

The same situation can also be a boon for your teenage or young-adult child where they can keep their data and file-based media on the older NAS. Here, it then makes it easier for them to shift their data out with them when they grow their wings and leave the family nest. Here, they can use this device with a DLNA-compliant media player to play out their music at their new location as well as operating it as extra / backup storage space for their computer.

Media storage in another location

Similarly, you may be responsible for another small home network such as one at your vacation or seasonal home; or the “family house”. Here, the older network-attached storage unit could serve as the hub of a DLNA-based network media setup for this location with similar media content, especially music and video, at that location.

Auxiliary data storage at your small business

The small NAS that has been supplanted by your larger or more flexible unit can work as an auxiliary storage service for your small business. An example of this is to keep a small-business NAS working the mission-critical data with high security while you have the small NAS doing tasks such as being a DLNA media server in the context of a smart TV or Blu-Ray player providing cost-effective digital signage for your business.

Conclusion

Therefore it doesn’t mean that you have to retire that small one-disk network-attached-storage device when you outgrow it and buy a newer better unit.

My Comments

Previously, I commented on a news article about Sony releasing a NAS that allows you to upload pictures from your Android device just by touching the device to this NAS. Now, Sony have premiered this device along with another mobile NAS at Mobile World Congress in Barcelona this year.

But there are two devices rather than the one device. The former device that I touched on previously allows you to upload photos, videos and other content to its 1Tb hard disk using USB file transfer, NFC or SD memory cards so you can effectively “dump” your pictures and videos from your smartphone, camera or camcorder, thus making way for new material.

The Personal Content Station can play the images to a regular “brown-goods” flatscreen TV using an HDMI connector or you can make them available through your home network using the open-frame DLNA standards. I would also like to be sure that you can transfer the images between your PC and this device using standard network file-transfer protocols like CIFS or HTTP. Of course there is the ability to use an accompanying app to “throw” the images to a social network, blog or other Website using your smartphone or tablet.

As well, the Portable Wireless Server can share the content you have on a USB storage device or an SD card to its own wireless network so you can quickly share “just-taken” photos with your smartphone, tablet or Ultrabook. This is becoming important with devices like the Dell XPS 13 which doesn’t come with an SD card slot or the detachable-keyboard hybrids that have a standard SD card slot only on the keyboard module.

The Sony Portable Wireless Server also works as an “external battery pack” for the many battery-thirsty gadgets that are important to our mobile online life. This is so true if you are dealing with the smartphone that serves as your mobile Internet terminal or your Walkman.

At least Sony is fielding devices that work as a team to satisfy the reality that confronts us through our online content-creation lives.

The current situation

A network-attached storage can come in handy for storing software updates rather than downloading them frequently

Operating system and application developers are now being required to provide updates for their products during the product’s service life and beyond. This is to provide for a computing environment that is performs in an efficient, secure, reliable and optimum manner. The updates may be released at regular intervals such as on a monthly basis or in response to a situation such as the discovery of a bug or security exploit.

New devices

A common situation that happens with most regular and mobile computing devices when a user takes delivery of them is that the user downloads a large data package to bring it up to date. This may be done many times if multiple units running the same platform are purchased.

Many devices

Similarly, a household may have multiple units running the same operating environment and they have to keep these up to date. The typical example of this may be a family with two or three children who are at secondary school. Here, they may have two or three computers for the children to use as well as one computer per adult. This could be brought about with the older child being given a more powerful computer as they enter senior high school or another computer given to the younger children as they start their secondary school.

But the same bandwidth would be used again and again to update each and every device. This may not be a problem for a couple with one device per adult but would be a problem when you are thinking of environments with more than two devices which is fast becoming the norm.

Using a network-attached storage to locally cache updates

Somehow the network-attached storage devices need to be able to support the ability to locally hold updates and patches for operating systems and applications used in computers on a home or small-business network.

The practice is performed frequently with large-business computer setups because of the number of computers being managed in these setups. But it could be practiced with home and small-business setups using a simplified interface. This could be based on the use of a local-storage application for regular or mobile client operating environments which supports this kind of local updating.

A local client application to manage system-update needs

Here, the local-client software could register which operating environment the host computer runs and what eligible applications are on the system so as to prepare an “update manifest” or “shopping list” for the computer. The “shopping list” would be based on the core name of the software, no matter whether different computers are running different variants of the software, such as home laptops running Windows 7 Home Premium while a work-home laptop runs Windows 7 Professional. This manifest would be updated if new applications are installed, existing applications are removed or changed to different editions or the operating system is upgraded to a different version or edition.

A local software manifest held by the NAS

This manifest is then uploaded to the NAS which runs a server application to regularly check the software developers’ update sites for the latest versions and updates for the programs that exist on the “shopping list”. There could be a “commonality” check that assesses whether particular updates and patches apply across older and newer versions of the same software, which can be true for some Windows patches that apply from Windows XP to Windows 7 with the same code.

At regular intervals, the NAS checks for the updates and downloads them as required. Here, it could be feasible to implement logic the check the updates and patches for malware especially as this update path can be an exploit vector. Then the computers that exist on the network check for new software updates and patches at the NAS.

Software requirements

Such a concept could be implemented at the client with most regular and mobile operating systems and could be implemented on network-attached storage devices that work to a platform that allows software addition.

It would also require software developers who develop the operating systems and application software to provide a level of support for update checking by intermediate devices. Initially this could require setups that are particular to a particular developer being installed on the client device and the NAS, but this could move towards one software update solution across many developers.

A change of mindset

What needs to happen is a change of mindset regarding software distribution in the home and small business. Here, the use of local network storage for software updates doesn’t just suit the big business with more than 50 computers in its fleet.

It could suit the household with two or more children in secondary school or a household with many young adults. Similarly a shop that is growing steadily and acquiring a second POS terminal or a medical practice that is setting up for two or more doctors practising concurrently may want this same ability out of their server or NAS.

Conclusion

The NAS shouldn’t just be considered as a storage device but as a way of saving bandwidth when deploying updates in to a household or small business who has multiple computers on the same platform.

The small data-replication cloud

These network-attached storage devices could be part of a personal data-replication cloud

Whenever the “personal cloud” is talked of, we think of a network-attached storage device where you gain access to the data on the road. Here, the cloud aspect is fulfilled by a manufacturer-provided data centre that “discovers” your NAS using a form of dynamic DNS and creates a “data path” or VPN to your NAS. Users typically gain access to the files by logging in to a SSL-secured Web page or using a client-side file-manager program.

But another small data cloud is often forgotten about in this class of device, except in the case of some Iomega devices. This represents a handful of consumer or small-business NAS units located at geographically-different areas that are linked to each other via the Internet. Here, they could synchronise the same data or a subset of that data between each other.

This could extend to applications like replicating music and other media held on a NAS to a hard disk installed in a car whether the vehicle is at home, at the office or even while driving. The latter example may be where you purchase or place an order for a song or album via the wireless broadband infrastructure with the content ending up on your car’s media hard disk so it plays through its sound system. Then you find that it has been synchronised to your home’s NAS so you can play that album on your home theatre when you arrive at home.

What could it achieve?

An example of this need could be for a small business to back up their business data to the network-attached storage device located at their shop or office as well as their owner’s home no matter where the data is created.

Similarly, one could copy their music and video material held on the main NAS device out to a NAS that is at holiday home. This can lead to location-specific speedy access to the multimedia files and you could add new multimedia files to the NAS at your holiday home but have this new collection reflected to your main home.

Here, one could exploit a larger-capacity unit with better resiliency, like the business-grade NAS units pitched at small businesses, as a master data store while maintaining less-expensive single-disk or dual-disk consumer NAS units as local data stores at other locations. This setup may appeal to businesses where one location is seen as a primary “office” while the other location is seen as either a shopfront or secondary office.

This kind of setup could allow the creation of a NAS as a local “staging post” for newly-handled or regularly-worked data so as to provide a resilient setup that can survive a link failure. In some cases this could even allow for near-line operation for a business’s computing needs should the link to a cloud service fail.

User interface and software requirements

This same context can be built on the existing remote-access “personal cloud” infrastructure and software so there is no need to “reinvent the wheel” for a multi-NAS cloud.

Similarly, users would have to use the NAS’s existing management Web page to determine the location of the remote NAS devices and the data sets they wish to replicate. This can include how the data set is to be replicated such as keeping a mirror-copy of the data set, or contributing new and changed data to a designated master data set or a combination of both. The data set could be the copy of a particular NAS volume or share, a folder or group of folders or simply files of a kind.

The recently-determined UPnP RemoteAccess v2 standard, along with the UPnP ContentSync standards could simplify the setup of these data-synchronisation clouds. This could also make it easier to provide heterogenous data clouds that exist for this requirement.

But one main requirement that needs to be thought of is that the computer systems at both ends cannot collapse or underperform because the link fails. There has to be some form of scalability so that regular small-business servers can be party to the cloud, which may benefit the small-business owner who wants to integrate this hardware and the home-network hardware as part of a data-replication cloud.

Hardware requirements

A small data cloud needs to support cost-effective hardware requirements that allow for system growth. This means that it could start with two or more consumer or SME NAS devices of a known software configuration yet increase in capacity and resilience as the user adds or improves storage equipment at any location or rents storage services at a later stage.

This could mean that one could start with one single-disk NAS unit at each location, then purchase a small-business NAS equipped with a multi-disk RAID setup, setting this up at the business. The extra single-disk unit could then be shifted to another location as a staging-post disk or extra personal backup.

Conclusion

What NAS manufacturers need to think of is the idea of supporting easy-to-manage multi-device data-replication “personal clouds” using these devices. This is alongside the current marketing idea of the remote-access “personal cloud” offered for these devices.

Network Technology

There are a few major trends that I have noticed for the home and small-business network at this year’s Consumer Electronics Show. But the big names like D-Link and NETGEAR had chosen to run private showings of their products in the many hotels around Las Vegas rather than use the Convention Center.

Wireless networking

The 802.11ac Gigabit wireless network standard has been ratified and a lot of the manufacturers are showing prototype chipsets and endpoint devices for networks based on this standard. TRENDNet had shown a router and a client bridge as a proof of concept for a wireless link on this standard and D-Link had registered interest in developing their 802.11ac implementation.

On the other hand, Belkin, D-Link and Engenius ran with premium “N900” routers as their top-shelf models. These are simultaneous dual-band routers that run three data streams on each of the two Wi-Fi bands with a total theoretical throughput of 450Mbps per band. 

As well, TRENDNet had tried their effort at another of those “universal Wi-Fi range extenders” which is a device class that could cause some mistakes.

Coaxial and Powerline Networking

MoCA have brought their TV coaxial-cable network specification up to 2.0 which allowed for a headline speed of 400Mbps with Broadcom showing a system-on-chip that works with this standard. They were pitching it at the set-top-box market, especially for multi-room cable-TV deployments.

On the other hand, HomePlug PowerLine Alliance have made the HomePlug AV2 specification official. This standard, which is interoperable with HomePlug AV powerline network segments can support MIMO / repeater operation for a robust powerline segment as well as allowing for a Gigabit physical-layer bandwidth for this segment. The former MIMO advantage makes it that each HomePlug AV2 node acts as a repeater and can take data from two or more nodes for higher throughput even with ropey mains circuits.

But there have been more of the HomePlug AV 500 devices being exhibited on the floor; including D-Link’s DIR-1565 “three-way” router which supports a network of 802.11g/n Wi-Fi, Gigabit Ethernet and HomePlug AV 500.

Also, the IEEE 1905.1 standard has been officialised thus simplifying the setup and management requirements for small networks that use Wi-Fi, Ethernet, HomePlug or MoCA network media or a combination thereof. It also provides a consistent quality-of-service arrangement for data that passes through the different network media.

Routers

Some of the manufacturers were pitching at the idea of “cloud-enabling” their routers. This was to allow for remote management of these devices or to allow the router to become an Internet-enabled file server. There was also some talk about setting up app platforms for routers, but what could this lead to for the evolution of these devices.

D-Link have launched the DIR-505 which is a 802.11g/n Wi-Fi plug-in travel router which also had the ability to work as an access point and file-server.

Network-Attached Storage

TP-Link had used this show to launch their first NAS unit which was a DLNA-capable 2-bay SATA unit with Gigablt Ethernet connectivity as well as 3 USB ports. It even had the ability to copy from USB to NAS at the touch of a button.

Iomega had refreshed their StorCenter NAS lineup by adding a surveillance-camera NVR functionality and making them easy to setup. This also included improving their cloud-storage functionality. They also introduced the EZ Media & Backup Center which was their entry-level home-user NAS which supported easy-setup operation and backup, iTunes / DLNA media serving and support for Iomega’s Personal Cloud and Iomega Link technology.

Broadband Internet

ViaSat, who provide the satellite backhaul for JetBlue’s inflight Internet service, were intending to launch a satellite broadband service for rural America this year. They wanted to use this show to exhibit their proposed service. This service is intended to be speed-competitive with the fastest terrestrial broadband services in the cities and is to be known as Exede.

The throughput is at a headline speed of 12Mbps download / 3Mbps upload and they are offering packages with monthly rates US$49.99 for 7.5Gb data allowance, US$79.99 for 15Gb data allowance and US$129.99 for 25Gb data allowance.

Conclusion

This year, the Consumer Electronics Show in Las Vegas was about estalishing a connected home lifestyle across all of the main activity centres ranging from the home office to the lounge area and that the TV is now a legitimate part of the connected lifestye.

Introduction

Netgear ReadyNAS as a music server

A new class of hardware has been brought about by the networked home and small office environment. This is in the form of the network-attached storage device which works simply as a hard disk that is attached to the small network, sharing its resources using common network protocols.

Description

A network-attached storage device or NAS is an appliance that connects to your home or small business network via Ethernet to serve as a communal storage device for that network. This is instead of purposing an older computer for this role of a common storage device.

One main advantage of these devices is that these devices don’t demand as much power as a regular desktop computer running as a server and they make less noise than the typical ATX desktop tower computer. Therefore they need less power to run and don’t need to have a constantly-running fan. This also leads to a device that is quiet and energy-efficient, values that are being asked of in this era.

The devices are typically very small, often ranging in size from a pair of cassette tapes through a small book to the size of a kitchen toaster for the small-business units.This means that they don’t take up much desk space and can even be hidden behind other computing devices, which also puts them in the good books with those who value aesthetics. This small size also wins favour with those of us who want a data storage to serve multiple devices but that can be quickly shifted to a location at a moment’s notice; as I have seen for myself at the Australian Audio and AV Show with a few of these devices working as DLNA-compliant media servers for demonstration hi-fi equipment. Infact the pictures of the Netgear ReadyNAS and the Seagate GoFlex Home NAS units are images of fully-operational units serving this aforementioned role, with the Seagate single-disk unit being photographed on the floor and it being slightly higher than the skirting board.

Disk Storage

Single-Disk NAS

Seagate GoFlex Home single-disk NAS

Cheaper consumer-focused NAS units are typically equipped with one hard disk with a few of these units like the Seagate GoFlex Home being a network bridge for a removeable hard-disk module that is part of the manufacturer’s modular-hard-disk system.

This also includes the portable NAS units like the Seagate GoFlex Satellite that are their own Wi-Fi network and are intended to work as a data offloading device for tablet computers.

But on the other hand, there are some single-disk NAS units like the QNAP range that can excel as highly-capable network storage hubs. In the case of the QNAP, these units are able work as full-flight Web servers suitable for serving intranets or “proving” Web-site prototypes; or pull off other advanced network-storage tricks.

Multi-Disk NAS

On the other hand, the better units will support two or more hard disks which work the installed hard disks as a RAID (Redundant Array of Independent Disks) that facilitate either extra capacity, higher data throughput or increased fault tolerance.These multi-disk units can be set up to have two hard disks of equal capacity “mirroring” each other as a safeguard if one disk fails or to facilitate high-throughput low-latency data transfer. On the other hand,the disks can be seen simply as a large volume of data. Units which support three or more disk drives can support disk setups that combine failsafe data storage and increased data capacity.

Some multi-disk units like the Netgear ReadyNAS units have the ability to support in-place volume expansion. This is where you can add extra hard drives to the NAS while it is running in order to build up redundant failover storage or increase system capacity. But other systems will require the NAS to be taken out of service if you intend to evolve the multi-disk RAID volume.

User-installed disks and upgrade options

Most of these NAS units have the hard disk integrated, which is at a known capacity whereas others, commonly known as BYOD enclosures, come simply as an enclosure where you buy the hard disk separately and install it yourself. A variety of multi-disk units do come with a single hard disk but you upgrade them to the RAID resilience or extra capacity by installing a hard disk in an empty disk bay. This kind of installation typically can be done without the need for tools in all of the recent implementations.

Of course, the cheapest single-disk NAS units don’t allow you to upgrade or replace the hard disk yourself, so you have to replace the unit if that hard disk fails or you outgrow the hard disk capacity. On the other hand, the better units permit the user to upgrade or replace the hard disk, thus providing for a long device lifespan.

External connection ports

A lot of NAS units have one or more USB ports so you can copy content off a thumbdrive or external hard disk, use an external hard disk as extra storage or a backup device for the NAS or use other peripherals. Some of them may use an eSATA port for the same purpose, especially to add storage or maintain a backup device.

It is also worth knowing that these ports may be used as a way of extending the functionality of the NAS devices through the use of various device classes; especially if subsequent firmware upgrades take place. Example applications include working as a print server for a USB-only printer to a camera server for a Webcam.

Functions

Network-central backup location

Most network-attached storage devices typically provide the ability to be a network-central backup device for all of the computers in that network. This is typically facilitated through manufacturer-supplied software or backup utilities that are part of a regular-computing operating system such as Windows Backup or Apple Time Machine.

Network-central file storage and drop-off point

They also work as a data-drop-off point where users can “park” redundant data or data being moved between computers and hard drives. This is facilitated using standard SMB/CIFS, FTP or HTTP machine-to-machine data transfer protocols which these operating systems can support natively. The computer may run a manufacturer-supplied “assistance” shell to help with locating the device or linking it to the computer.

In the same extent, the NAS may work as a shared data library for software and data that is needed across the network. This would include utility software, device drivers, updates and patches as well as documents of common interest.

It is being extended to mobile computing devices like smartphones and tablets through the use of manufacturer-supplied or third-party network-file-transfer apps for the common mobile-computing platforms like iOS or Android. I have covered this topic in an article about moving data between your NAS and your smartphone.

Media server

This now covers the ability to share media files like digital images, music and video files to every computer and DLNA-compliant media device across the network.  This is facilitated through an integrated DLNA media server for standards-compliant devices and an iTunes-compatible server for iTunes media managers including Apple iOS devices.

But some manufacturers are targeting some of their consumer-focused NAS units at the distribution of media files across the network. These will typically have software that provides for low-latency transfer of audio and video content as well as an improved DLNA media server. Some of these DLNA media servers may support content-metadata aggregation where they index all media held on every DLNA server in the network and become the single point of reference for that media.

Some of the NAS units like RipNAS, ZoneRipper or Naim UnitiServe may even have an integrated optical drive to allow you to “rip” CDs to the hard disk or allow you to connect an optical drive to their USB port so you don’t have to power up a computer to “rip” new CDs to your media collection.

Remote access and the personal cloud

A new capability that is being promoted by NAS vendors such as Western Digital and Iomega is remote access, commonly marketed as a “private cloud” or “personal cloud”. This requires the NAS to have server software that exposes its location to a cloud service on the Internet and manage access to the data from Internet-based users. It works alongside client software available for regular or mobile operating systems to enable users to transfer the data outside their home network.

Variants of this software, such as what Iomega offer, may support peer-to-peer data transfer between multiple NAS units installed at different locations. This could cater for multi-site content replication or simple offsite data backup requirements.

Platform NAS systems

An increasing number of high-end NAS units have the equivalent of an app store, where the manufacturer can provide free or paid file-handling programs that load on to these devices. These can include a simple photo-viewing intranet app, a DVR for video-surveillance apps, an email server or a download / Bittorrent manager amongst other things.

Some systems like the QNAP units deliver every function in one “hit” when the user purchases the NAS devices whereas others just maintain the “app-store” or “download-point” for users to add the functions on at a later time.

What should you get

A single-disk NAS can serve a typical household well as a data drop-off point and media server. It can also augment a small-business’s server by fulfilling low-risk tasks such as DLNA media-server functionality thus keeping the server for business-critical needs. The high-end varieties of these single-disk NAS units like what QNAP sells would work well for those of us who want more functionality such as a Web-development workbench or a DVR for an IP-based video-surveillance system.

If you end up with more devices in your home and you want to be sure of continuity or expandability, a multi-drive system would fit your bill. You may go for a multi-disk system that has one hard disk installed so you can upgrade to resiliency or extra capacity at a later time.

Small businesses should consider a good multi-disk MAS that has what it takes to support increased resiliency. In some cases, a small business may operate the multi-disk NAS as a backup or file-archive device for their site’s main operational server; as well as a media server or similar application.

It is also essential to look at an offsite backup option for these units, such as the ability to connect a USB external hard drive for the duration of a backup job or the ability to backup to another NAS or cloud service via the Internet.

Mandatory features

For basic functionality, the NAS should support the SMB/CIFS and NFS network file protocols and have an integrated DLNA and iTunes media server. The computer-NAS backup options can be hosted with manufacturer-supplied software bout should work with Windows Backup or Apple Time Machine options.

I would also prefer that the NAS supports a continual software upgrade path for its functions. This is where the manufacturer keeps the firmware up to date as new standards come about, thus opening up the door to newer functionality and better performance.

The connection to the networks should be at least one Gigabit Ethernet port in order to support higher data throughput. You may not get this throughput with your existing router but if you upgrade to a newer router that has Gigabit Ethernet ports, you will end up with significantly higher throughput which would benefit applications like movies or high-quality music files.

Conclusion

Once you have a network-attached storage device in place, you will never know what capabilities these devices will open up to the connected home and small business. It doesn’t matter whether it’s a backup location for your computers or a media server or just simply a “file parking lot” for your home network.

When I talk of laptops, wireless routers and network-capable printers, I make frequent references to a “new computing environment” that these devices can enable.

What is the “New Computing Environment”

The “New Computing Environment” is a home computing environment that is based around portability and flexibility. The seed for this environment has been sown with the widely-publicised Intel Centrino campaign and is becoming stronger in a lot of households.

It consists of most of the computers in the house being laptop or notebook computers.It may also include the use of “all-in-one” desktop computers similar to the newer Apple iMacs or HP TouchSmart desktops. The goal is that these computers are able to be moved easily around the house at a whim.

This environment will also encompass the use of smartphones and tablet computers for secondary computing activities like casual Web browsing, email and use of social networks.

There is a Wi-Fi home network in place that is served by at least a wireless router that is the network’s Internet “edge”. The computers may connect to that router via Ethernet if they are close to it but are typically connected to that router using the Wi-Fi network segment.

What does this lead to

Increased flexibility

The key benefit is to increase flexibility when it comes to computer use. The major benefit is that you can relocate the computer as you need it. An example that was portrayed in an Intel Centrino radio ad that was played in the UK was someone who was writing out an email on a laptop being being interrupted by another household member who had come in to do the vacuuming. Then they are able to move somewhere quieter to do the rest of their work.

Netgear DG834G ADSL2 wireless router

As well, the “New Computing Environment” also leads to increased “casual computing” setups like viewing sites like YouTube or Facebook while lounging around on the sofa; going through one’s email while relaxing in bed or flicking through online news sites while in the kitchen. I even wrote a short article on this site about the trend of young people visiting Websites while watching TV.

Catering to temporary workspaces

Another very common scenario is a household without a dedicated workspace. This is where the kitchen bench or the dining table becomes a temporary office. Some households may have a collapsible table like a card table or trestle table along with one or more folding chairs, set up in a lounge area or landing for use as a temporary workspace; or may have such furniture on hand to set up a temporary workspace as required. The “New Computing Environment” allows the user to shift the computer along with the rest of their work whenever they need to do something like set the table for a meal.

Even if a household has a dedicated workspace, there will always be the need to create another temporary workspace to suit another person’s work or study needs or to suit a different type of work.

Storage flexibility

Similarly, laptop computers are much easier to store when not in use. For example, they can be put in a drawer when not needed, as I have mentioned in an older article regarding use of a laptop as a kitchen PC. This allows the machine to be well out of harm’s way which can be of concern in a busy household or with some children and pets.

As well, the laptop is also more suited to households who have older “davenport” or “roll-top” desks which are capable of being closed up when not in use. Here, these computers can be used at and stored easily in these desks. It also allows these desks to become the elegant piece of furniture that they are known for.

Suitability with “downsized living”

This computing environment is becoming increasingly relevant with people who live in smaller houses and apartments; especially city apartments.

This class of user includes “empty-nest” parents who are moving to smaller premises because their children have left the family home, but still need to be able to look after their grandchildren when they come around.  Here, their computing equipment doesn’t need to cause much space to be taken up in these smaller living quarters.

The “home-business” laptop

This kind of computing environment also suits the use of a “home-business” computer that is used at home but taken to the workplace while you are working. For some small-business operators, a large laptop like the Dell Inspiron 15R or the HP Probook 4520s may be the only computing device that they need to use for all their computing needs and you just pack this machine in the boot (trunk) of your car before you head to or from your workplace.

Implementation notes

Starting out

You will need to use a laptop computer that is commensurate to your computing needs. But it will have to be equipped with an integrated Wi-Fi wireless network interface of at least 802.11g WPA standard. This covers most laptops made over the past five years. I have reviewed plenty of laptops and notebooks on this site and will be reviewing more of them as they come along from different manufacturers. You can have a look at the list of equipment reviewed here on this page.

If you are intending to buy a new laptop computer, I would suggest that you look at the buyer’s guides that I have written – “Buying a Laptop or Notebook Computer”. Here, I have suggested the use of the 15” laptop computers as a sole or main computing device for this environment. If you have very basic needs like emailing and basic Web surfing, a unit equipped with a low-end processor and around 2Gb memory, like the Compaq Presario CQ42 that I have reviewed here, can suit your needs here. It is still worth it to spend as much as you can afford on the hard disk capacity because as you use the computer more regularly, you will end up filling the hard disk more quickly.

On the other hand, you may want to use an “all-in-one” desktop computer like one of the Apple iMac, HP TouchSmart Desktop or Sony VAIO J or L Series computers. These have the computing power, secondary storage and the screen integrated in one slim lightweight housing, with a separate keyboard and mouse. They may be useful as a “common” or “family” computer and can be stored or moved easily as long as you know how to reconnect the keyboard and mouse.

Printers

A lot of people who set up for the “new computing environment” typically use a direct-connected printer and bring the laptop closer to it in order to plug it in when they want to print or scan something.

What you need to do for proper implementation is to use a network-enabled printer. Here, these printers connect directly to the network either via Ethernet or Wi-Fi wireless and accept their print jobs through this connection. Multi-function printers can also expose their other functions like the scanner, fax or memory-card slots to the network.

This avoids the need to connect the laptop to the printer every time you want to print something out. With a network printer, you just select that printer from the list of printers when you specify a print job from your laptop and, moments later. you will find your print job in the printer’s output tray. Here, the job is sent via the network to the printer rather than via a cable that you always connect to the printer.

“Easing the gap” towards flexibility

Some users who are used to a regular laptop computer connected by Ethernet to a single-port broadband modem at a regular workspace may still get in to the habit of connecting the laptop to the wireless router using the “old way”. This is more so if they see their computer’s home location as being on the desktop near the router and while at that location they plug it in to the Ethernet socket on the router.

Some operating systems may react in a strange way if the user plugs in the Ethernet connection while the wireless connection is still active. This may be not of concern with newer operating systems that can automatically deactivate the Wi-Fi wireless network interface if the computer is connected to the network via an Ethernet cable.  Here, the user needs to know how to manually enable and disable the Wi-Fi wireless network interface in the laptop.

Some of the computers will use a separate “Wi-Fi” button to turn the Wi-Fi modem on an off whereas more recent examples will require you to press the “Fn” key and a function key with a transmitter symbol to turn the wireless network on and off. This function may also be known as a “flight mode” and in some cases, will turn the Bluetooth function on and off at the same time.

Then what you might end up doing is to forget using the Ethernet cord and just use the laptop wirelessly as you realise you can use the Internet at home without wires.

Network-attached storage devices

If you are considering expanded or secondary data storage space for the “New Computing Environment”, you will be interested in buying a network-attached storage device. This is a dedicated external hard disk that is accessible from computers connected to your network. It is different to the idea of repurposing an old desktop computer as a shared storage server because the device is designed specifically to be a storage device and will end up being quieter, more efficient and more reliable to run than the old desktop computer.

They are relevant as a backup device; to offload rarely-touched data from your computer and/or to works as a standards-compliant media server for your music, digital pictures and videos. I have touched on this latter application in the DLNA Home Media Network series article: “Setting up for PC-free operation”.

An increasing number of wireless routers are offering NAS functionality when a USB hard disk is plugged in to them. This may be good for starting out or a temporary network-storage solution but a dedicated network-attached storage device can do the job much better for long-term use. As well, most of the routers that offer this function are very under-powered when it comes to handling USB hard disks and you would then have to use a self-powered USB hard disk or connect the “power” USB connection on small USB-powered hard disks to a powered USB hub.

Is wired technology relevant to the New Computing Environment

There are some cases where wired-networking technology is relevant to the New Computing Environment. One main case would be to support network printers or networked AV devices that don’t have integrated Wi-Fi functionality. This would be more so as you consider purchasing an Internet-enabled TV or Blu-ray player for your home and a lot of these devices may just have an Ethernet socket rather than Wi-Fi connectivity.

Another case would be to use a secondary access point to extend wireless-network coverage, such as with buildings that use thick walls made of brick, stone or similar materials; large buildings or outbuildings on a property.

Here, you may think that you have to lay Ethernet wiring through the premises and this may be expensive and of poor value if you aren’t renovating, extending or rewiring your building. In most cases, you could use HomePlug AV technology as your wired “no-new-wires” technology because this uses regular AC wiring as a data carrier.

Conclusion

What I am hoping to do with this is to explain the “New Computing Environment” that is becoming a major trend as far as home and small-business computing is concerned. This is where the computing environment is centred around the use of portable computers that connect to a wireless network.
