Fundamentals of a Well-Built SAN
Source: Hewlett-Packard (HP)
Every SAN is built from a combination of software, hardware, and services, and in this respect iSCSI SANs from HP are no different from any other SAN. But that's where the similarity ends. HP LeftHand SANs use distributed clustered technology to deliver all of the functionality expected of a storage area network. They add the advantage of linear scalability, high availability, per-logical-volume configured reliability, and throughput of 10-Gb/s per node that is aggregated between all nodes in a cluster. Better by design, HP LeftHand P4000 SANs deliver functionality including synchronous replication, asynchronous replication, and remote copy. These are built-in features of a superior architecture - not an add-on option that can cost as much as an entire SAN.
