LSI has acquired StoreAge Networking Technologies, one of the last remaining independent storage virtualisation vendors.

LSI picked up StoreAge for US$50 million and will add its software to the Engenio storage systems it sells through IBM and Sun.

StoreAge's Storage Virtualisation Manager is out-of-data path software installed on a switch-based appliance, which pools storage resources around a storage-area network. The company also has snapshot copy, replication, disaster recovery and migration software, which LSI will also add to its Engenio range.

The acquisition leaves Incipient, whose technology is closely tied to Cisco switches initially, as the last independent vendor of storage virtualisation software. IBM has its own SAN volume controller; EMC has Invista and has acquired Rainfinity to bolster its network-attached storage virtualisation capability. FalconStor and DataCore have virtualisation software that runs on appliances sitting in the data path.
The deal is expected to close by year-end.
