Symantec is updating its line of backup products and releasing a virtualization package combining the vendor's own storage management software with Citrix's Xen hypervisor.   

Symantec's Veritas Virtual Infrastructure integrates the vendor's storage management with Citrix XenServer, letting administrators manage both server and storage virtualization through a single Web-based console, Symantec officials say.

Virtualization of servers and storage are complementary technologies, but can sometimes be difficult for IT shops to coordinate, the vendor says. (Compare storage products.)  

Symantec is announcing the new virtualization tool on Tuesday in conjunction with the Symantec Vision 2008 conference.

"Server virtualization makes storage management more complex and in many cases does not support capabilities available today in physical environments," Symantec states in a press release. "Current x86 virtualization solutions have tried to solve this problem using a file system-based approach, but this architecture forces users to give up many of the advanced storage-management capabilities they rely on today."

It can be difficult to manage the storage available to virtual machines when administrators lack failover capabilities and mirroring of application data across separate storage arrays, says Sean Derrington, Symantec's senior director of storage management.

"There are a number of core capabilities that most organizations take for granted in the physical world," but aren't able to do with virtual servers, he says.

Features of Veritas Virtual Infrastructure include direct control of block storage from guest virtual servers, sharing of boot images across multiple virtual servers to reduce storage costs, and load-balancing capabilities.

Rather than build its own server virtualization software, Symantec is relying on Citrix, which began challenging VMware with the purchase of XenSource last year. Veritas Virtual Infrastructure will be available this fall at prices starting at $4,595 for each two-socket server.

Backup updates

Symantec also described several updates to its Netbackup suite of backup software. NetBackup RealTime was updated with a continuous data-protection feature that helps recover from failure by recording data at all times.
