Access "Protecting virtual machines"
This article is part of the Vol. 6 No. 12 February 2008 issue of Storage Products of the Year Awards 2007
Talk to a server administrator and you'll hear great praise for virtual machines (VMs), which hold dozens of server images on a single machine. Talk to a storage admin who has to protect those images and a different view unfolds. It costs more to protect VMs than physical servers. But because VMs are easy to set up, they multiply quickly and are often used for short-lived, small-capacity projects. Afterwards, the VM will likely be forgotten while its storage space still exists. Bryan Semple, VP of marketing at Onaro (to be acquired by NetApp), says storage teams often allocate large blocks of storage to VM teams, bypassing "classic control and cost oversight models." In addition, VMware uses large LUNS, which may create concerns over the performance array ports can deliver, resulting in underprovisioning. Onaro has released plug-in module VM Insight to monitor servers and check performance. And VMware's Dunes Virtual Service-Orchestrator helps monitors VMs. --Rich Friedman Access >>>

More Than Just Backup
Data protection is changing rapidly, with point-in-time recoveries, fast legal discovery response and near real-time disaster recoveries becoming new requirements. To address these needs, enterprise backup applications are adding support for continuous data protection, deduplication, ediscovery, single-instance storage and the VMware Consolidated Backup framework. These backup suites promise not only integrated data protection, but overall enterprise data management.
