Access "Swap tape for removable disks"
This article is part of the Vol. 6 No. 1 March 2007 issue of Using file virtualization to improve network-attached storage
Removable disk cartridges are faster than tapes and easier to manage--but don't dump that tape library just yet. New removable disk drives represent the next step in data protection: the best features of disk and tape. Combining the speed and reliability of disk with tape's portability, removable disk drives foreshadow an impending change in the way companies will back up and restore data in the not-too-distant future. Some of the benefits removable disk drives offer vs. tape include the following: Drives appear to back up software as a disk, file system or virtual tape image Disk packs come with different RAID options Faster backup and restore times Disk drives maintain persistent drive letters in operating systems Most small- to medium-sized business (SMB) backup software products support removable disk drives. But widespread adoption of portable drives may be inhibited until some problems are solved. For example, removable disk drives cost more per gigabyte than tape cartridges, and they aren't compatible with some major backup software products and ... 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?
by James Damoulakis
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.
