LeftHand Networks Inc. pioneered the open iSCSI SAN market and is the only storage vendor to build enterprise-class SANs on industry-standard platforms. A key differentiator for LeftHand is its patented SAN/iQ storage clustering software. LeftHand’s SAN/iQ software turns standard servers like the HP ProLiant DL380 into scalable network storage ideal for primary storage, server consolidation, disaster recovery and campus SANs. LeftHand was acquired by Hewlett-Packard Company (NYSE: HPQ) in November 2008.
