  SnapServer 4100 Review 
  May 11, 2001, 08:00am EDT 


By: Sander Sassen

Traditionally networks were setup as a server-client system, a server and a number of workstations; clients. All of the network storage was centralized in the server; the server does everything from file serving to authentication, email, etc. If the server crashes or is down for maintenance or a storage upgrade, productivity simply stops, as the clients don't have any file serving or management capabilities; this is known as the server-centric model. Obviously, server crashes or downtime due to upgrades or maintenance do not create a desirable situation for most companies. Worse still, upgrades, management, maintenance, etc. must either inconvenience users or be done in the weekends or overnight, which isn't a satisfactionary solution either.

With the introduction of NAS, Network Attached Storage, about two years ago, companies and individuals alike now have an easy and efficient way of simply adding network storage. A NAS server is in reality nothing more than a small server that is optimized for file sharing, and doesn't have the other services and overhead that conventional servers have. That is, NAS does not offer email, file management etc, but is an easy-to-set-up device that allows you to easily add storage capacity to your network even if you already have one or more servers.

The problems with server-centric storage, combined with desire to not compromise productivity, have led to a new way of designing server-client systems where the actual storage is no longer an integral part of the server. The users needs for immediate access to data and the ability to upgrade network storage at any given time, without affecting productivity, is much better handled by the storage-centric model. In a storage-centric system the server still handles all the processing such as needed for file serving, authentication, email, etc. but the server doesn't have to do deliver the data to the client. As an added advantage the actual network storage can be located anywhere in the network and is not physically a part of the server, and can consist of one or multiple NAS devices.
