They have all the features that EqualLogic has plus more. Not only do they virtualize within a box, but across boxes. LeftHand's Network RAID stripes and replicates data so that a cluster of arrays can accommodate a double disk fault (second drive in a RAID set failing while rebuilding a failed drive using a spare), a complete array failure, or a site failure. This comes in handy when using VMware VMotion and HA. These VMware capabilities require that the underlying storage is still in tact when failing over or moving a VM. With LeftHand, a site can be brought down, the VMs failover seamlessly and the SAN is still available. My understanding is that LeftHand is the only one that can do this over IP.<BR/><BR/>If you have servers with storage in them, and you don't have budget to by a SAN from LeftHand, you can take a version of their software that's shipped with their SANs and run it in a VM on each server (called VSA), and it pools all disks from your servers into a shared SAN, and it looks and is managed just like an external SAN.<BR/><BR/>LeftHand has definitely taken storage virtualization to the next level. You can download a fully featured trial version of VSA from their web site for free. It's a good way to evaluate LeftHand's capabilities without having to install and configure hardware.Johnhttps://www.blogger.com/profile/16194466388169016620noreply@blogger.com
