IBM has signed an agreement with Hitachi Data Systems to provide software interoperability between the companies' enterprise storage arrays.
IBM has licensed API technology to Hitachi for IBM's Enterprise Storage System known as Shark. Hitachi will share peer-to-peer remote copy and extended remote copy capabilities with IBM Shark users. Hitachi users can use IBM's FlashCopy, Multiple Allegiance and Parallel Access Volumes. Through the agreement, IBM can support Hitachi's Nanocopy and ShadowImage on its Shark server. Users of both companies' gear will be eligible for free upgrades.
