LeftHand Networks' next generation SANs provide superior data availability, scalable performance, and a best-in-class storage management feature set. We can provide these features at an affordable price point because, unlike legacy storage systems, our iSCSI SANs are built upon a distributed clustered architecture. The essential building block of a LeftHand SAN is the storage node: a compact, high availability server that contains its own processing power, RAM, cache, disk drives, and bandwidth.
