Move over Lefthand Networks VSA, xtravirt.com has provided a free alternative for creating a virtual iSCSI SAN. Xtravirt Virtual SAN (XVS) is a virtual machine appliance that runs on two of your ESX hosts’ local VMFS datastores to create a single, synchronized iSCSI SAN. XVS allows the creation of ESX clusters for VI3 Enterprise features without purchasing a physical shared storage solution.
“The Xtravirt Virtual SAN (XVS) appliance for VMware ESX3 Server is a free solution to provide the benefits of shared VMFS storage without the cost of a SAN – this allows the utilisation of otherwise unused local storage in the ESX server to facilitate enterprise level features such as vMotion, DRS and HA normally only available through the use of a shared storage device. All volume data is synchronously replicated between hosts, providing full fail-over capability with data integrity in the event of host, disk or appliance failure.”
XVS is the perfectly priced storage solution for the home ESX test lab, small and mediium businesses, or the small remote branch office.
To download a copy of the virtual appliance and for more about XVS go to xtravirt.com.
updated 5.24.08
Currently XVS is only configurable as a single LUN across paired ESX hosts. A third ESX hosts can use the virtual ip address for it’s SAN, but the additional host(s) would not be using their local storage as part of the synchronized SAN. Future editions will hopefully expand the storage across more than 2 ESX hosts.
