HP LeftHand SANs use distributed, clustered technology to deliver all of the functionality expected of a storage area network. They deliver functionality including synchronous replication, asynchronous replication, and remote copy.
Next to its people, data is a company's most valuable asset. Businesses of every size rely heavily on data that is at once increasingly complex and increasingly regulated. Government regulations in countries around the world dictate how financial, customer, personnel, and health-related information is stored, maintained, and retained.
