Access "Per-protocol pricing gets murky"
This article is part of the Vol. 6 No. 1 March 2007 issue of Using file virtualization to improve network-attached storage
As arrays that offer support for Fibre Channel (FC), iSCSI, CIFS and NFS within the same box catch on, pricing and support for these devices is becoming more complicated. According to Network Appliance, which supports all of the above protocols in a single system, protocol fees are applied depending on the type of configuration a customer purchases. The company, however, doesn't explain how these protocol fees break down. Per-protocol pricing "is still common practice with NAS technology," says an official at EMC, which charges separately for CIFS and NFS support. On the SAN side, however, EMC will toss in iSCSI support at no extra cost. Users should be careful of license fees vs. support fees, as these are often two separate charges. On the other hand, Adaptec says its new Snap Server 650 supports iSCSI, CIFS and NFS for one price. If simplicity is important and FC isn't a requirement, there's one answer. --Jo Maitland Access >>>

Rein in NAS with file virtualization
NAS filers have sprung up largely unchecked in many companies, creating major management headaches and forcing companies to reevaluate how they handle this critical piece of storage infrastructure. File virtualization appliances can address multiple filer pain points by pooling disparate storage, providing a global namespace and making short shrift of data migrations.

Are you ready for new compliance rules?
Two things to know about storage and regulator compliance: There's no single technology product that meets all compliance requirements and there's plenty of prep work to do before you even think about technology. The first step is to define your unique requirements, including compliance and litigation-readiness needs, as well as business productivity and service-level objectives.

Power costs put the squeeze on storage
Storage shops keep growing and growing, adding capacity to keep up with the business. But the cost of powering all that additional capacity and keeping it cool is growing, too, and some data centers are being pushed to their limits. Thinking green can help stem the tide of soaring power costs and also help you figure in the cost of end-of-life disposal for your aging equipment.
Swap tape for removable disks
New removable disk drives combine the speed and reliability of disk with tape's portability. But widespread enterprise adoption may be inhibited until problems, such as costly disk drives and incompatibility with some major backup software products and automated tape libraries, are solved.

Are backups a waste of time?

Data protection is now much more specialized due to increased user expectations and new technology options. We need to rethink the way we approach risk and risk-related services.
iSCSI: Learn it or be left behind
by Jon Oltsik
Thought you might get by without considering iSCSI storage? Think again. With continuous progress on the iSCSI protocol and steadily improving products, the technology is now gaining enterprise stature. Savvy users should prepare themselves now for iSCSI.
We're in the midst of some seismic shifts in the storage world
Storage Bin: Changes in the tech world can evolve subtly or may hinge on a big, revolutionary event. Either way, we're in the midst of some seismic shifts in the storage world, and both vendors and IT pros will have to adjust to a new world order.
