LeftHand Launches Virtual SAN Appliance for VMware Environments
LeftHand Networks says its new Virtual SAN Appliance (VSA) will enable small and medium businesses (SMBs) and remote and branch offices to realize the benefits of server virtualization without sacrificing high availability.
Demonstrated recently at VMworld 2007 in San Francisco, the VSA is designed to cluster the internal storage within multiple x86 server hosts running VMware’s ESX Server. The clustering action creates a storage-area network (SAN) that provides high availability for both virtual and non-virtual applications.
According to John Fanelli, vice president of marketing for Boulder, Colo.-based LeftHand, virtualization provides a lot of benefits, including server consolidation, where more than one application can sit on a server. Companies get better utilization and have to manage fewer servers. “However, if that one server should have a problem, you are now putting (several) applications at risk instead of one, which is clearly a bad side effect of virtualization and server consolidation,” he said.
