Access "The future of virtual machine backup"
This article is part of the Vol. 4 No. 10 December 2005 issue of Five ready-for-prime-time storage technologies
The data center will have a very different look five years from now. Here's a prediction: lots and lots of virtual machines running on VMware, the open-source Xen, Microsoft's Virtual Server or some other yet-unknown platform. In 2004, total market revenue for virtual machine software grew at 30%, says Dan Kusnetzky, VP of IDC's system software research, with VMware enjoying the lion's share of the market. In the coming years, he says, "open source and a highly competitive market will drive down the price" of virtual machine software—and thus of revenue growth—but "it will not in any way slow down the adoption." Storage managers responsible for data protection may be wondering whether virtual machine backup happens any differently than it does on single operating system/single server systems. In theory, there's nothing about a virtual machine that says you can't back it up the old-fashioned way: by installing a backup agent that traverses the file system. The problem some VMware shops have had with that traditional file-level backup is performance, says ... Access >>>

Smart career moves
It's a good time to be working in storage, but no matter what your background or training, gone are the days when you could count on your company to have the same concerns about your career that you do. Here are some steps you can follow to take control of your storage career.
Larger SANs drive storage growth
Storage's exclusive Purchasing Intentions Survey polled 524 storage professionals. The survey suggests that storage managers are moving away from many small SANs to fewer, larger SANs that can power more services and connect to more places.

Get ready for virtualization
The benefits of virtualization are apparent, but getting there is another matter. Many products can deliver some form of virtualization, but behind the promises of storage utopia looms vendor lock-in. But even if the rewards are greater than the risks, you still need to assess which virtualization options are mature enough to deploy.

Hot Technologies for 2006
by Alan Radding
Storage's editors considered a wide range of technologies before settling on the five that we feel will be the hottest storage technologies for 2006. Among the many technologies available to storage shops, we see e-mail archiving, midrange arrays, virtual tape and disk-based backup, SAS/SATA drives and remote office support emerging as the technologies that will be most in demand next year.
NAS consolidation options
There are four main ways to consolidate NAS--upgrading to larger traditional NAS boxes, clustered file systems, parallel file systems and NAS aggregators. We help you determine the best consolidation option for your storage environment.

Storage market is a soap opera
Storage Bin: The storage market is a soap opera filled with subplots and backstabbing. But trying to win business by lying about your competitor's product or service is a loser's maneuver.
Get ready for real ILM
ILM product initiatives today generally amount to little more than repackaging old products with new names, says Stephen Foskett. But you can still get ready for real ILM with tiered storage, consolidation and a service-oriented approach.
