Snia On Storage
End-user benefits will include simplified-and lower-cost-SAN management.
In our conversations with end users-and, for that matter, vendors-it's surprising how often the subject of "interoperability" comes up. Users consistently complain about the lack of interoperability between storage products-hardware and/or software-from different vendors.
Often included in storage resource management suites, chargeback functionality holds users (and customers) accountable for their storage usage.
End users want options in enterprise licensing structures, and vendors are not always providing the required flexibility.
Securing data in a SAN requires controlling access at all levels, including physical, network, storage device, host, and administrator.
A relational database technique called normalization helps explain how network-based virtualization can simplify SAN management. By Jerome M. Wendt

Are you running out of database disk space, or paying for expensive disk capacity that you don't really need? Is "database bloat" bringing your applications to unsatisfactory performance levels?
EMC recently announced its sixth-generation Clariion product-the CX600. For those awaiting a next-generation Symmetrix array, the CX600 was somewhat of a letdown, but for mid-tier markets it was welcome news because the new array fills a long-standing gap in the company's Clariion lineup.
With more and more IT dollars going toward storage (see chart), administrators are increasingly finding themselves in the difficult position of having to justify hardware and software purchases to senior- level management.
Leveraging its investment in Linux, Quantum's Storage Solutions Group (formerly Snap Appliances) is integrating its latest network- attached storage (NAS) server with the company's tape drives and SyncSort's software for local backup-a feature that was lacking in its previous NAS products.
Hoping to change the way large companies migrate data, Southboro, MA, start-up SANgate Systems recently announced its first product, SANblaster S1000, which the company claims is the first dedicated, non-host-based data migration tool.
Although Serial ATA disk drives are not expected to become widely available until early next year, a variety of vendors have started to introduce products designed around the new specification.
If your storage environment includes network-attached storage (NAS), chances are good that you have backup problems. While there are a variety of ways to back up NAS appliances, these methods have generally been difficult to manage, expensive to implement or, in some cases, just plain inefficient.
Over the next six months, more and more vendors will be shipping automated policy-based storage management software, which analysts say is the next evolutionary stage for storage resource management tools.
Claiming to be the first systems vendor to offer storage management software based on the Common Information Model (CIM) standard, Sun Microsystems recently released its StorEdge Enterprise Storage Manager (ESM) software.
With Dell, IBM, Intel, and Oracle at its side, Veritas Software this summer set its Linux strategy in motion for enterprise computing-a market Veritas and other storage vendors believe is now ripe with opportunity.
Storage resource management software is the first step in understanding-and controlling-out-of-control management costs.

<b>Q: </b>Our research group is running analyses on files ranging from 50MB to several hundred megabytes in size. Performance was fine when a single computer was able to do all the work, but as we've moved the files to a file server and added more computers, performance has become unbearably slow. Can we use storage area network (SAN) technology to improve file-server performance?
