Anyone reading a storage-related article in the last few years has probably come across research citing "exponential storage growth." Organizations today are requiring an increase in network storage capacity at a constantly growing rate.
Much of this growth comes from unstructured file-based data, including network-stored word-processing documents, presentations, spreadsheets, JPEG and GIF files, music and video files, and so on. According to IDC's Enterprise Disk Storage Consumption Model, the annual capacity growth rate for unstructured data in traditional enterprises is projected to grow by 62.2 percent in 2009 compared to a 54.4 percent growth rate in 20061.
Storage growth is being driven by multiple factors including regulatory compliance, pervasive computing in a "keep-everything culture,"2 and lower cost storage hardware; the latter being the principal method of organizations addressing their storage growth needs.
But what is the value of an organizational policy of storing data on cheap storage when the data are not being managed? Without a storage management system in place, information can become lost, duplicated, harder to retrieve, more costly to manage manually, and cumbersome to the network where the storage resides. More serious risks might come in the form of litigation or negative audit findings.
This exponential growth in storage and the corresponding management dilemma it exposes is what makes the release of Novell Storage Manager 2.5 compelling.
Novell Storage Manager provides identity-based life cycle management of user and group network storage resources. It helps minimize the risks outlined above through automated policy management, ensuring compliance with organizational, industry and government regulations for secure data storage management. (See Figure 1.)
As storage offerings, capabilities and practices have changed, so has Novell Storage Manager. This month, Novell introduced its updated Novell Storage Manager 2.5. This new version includes some remarkable product enhancements designed to address the changing role and needs of storage. Some of the more notable enhancements are summarized below.

Novell Linux Support
As Novell-networked organizations expand their environments to include SUSE Linux Enterprise Server or Novell Open Enterprise Server running SUSE Linux Enterprise Server, Novell Storage Manager 2.5 addresses this expansion with Event Monitors that can be hosted on servers running either Novell Linux offering. Agents (known previously as "Sentinels") can now be hosted on Novell Open Enterprise Server running SUSE Linux Enterprise Server. New supported file types include OES 2, ext2/3 and Reiser if you have the NCP extension.
Auxiliary User Storage
Auxiliary user storage is a new enhancement that was also added at the request of many enterprise customers. This allows administrators to create a policy in eDirectory that creates auxiliary storage folders when a new user is created. There is no limit to the number of auxiliary folders that can be created. Auxiliary folders can be created in volumes that differ from those at the user's home directory location.
Collaborative Storage Enhancements
An administrator can now create collaborative storage based on an OU object itself without having to first create a Group object. Once a policy has been created for the OU, a user added to the OU will have rights to the collaborative storage area where he or she can work with others.
Novell Storage Manager 2.5 also extends its powerful file vaulting and grooming capabilities to collaborative storage. Now, you only need to set collaborative storage vaulting policies for aged files and unallowable file types. And just like user file vaulting, these files will be moved to a vault location on less expensive hardware or they may be deleted altogether.
Finally, many network administrators that are in the process of consolidating servers will appreciate the ability Novell Storage Manager 2.5 has to migrate collaborative storage. By simply changing the storage location path within the collaborative storage policy, the collaborative storage can be migrated automatically to a new storage hardware device.
