Magic Quadrant for Midrange Enterprise Disk Arrays, 2H07 "Hitachi Data Systems' (HDS's) AMS/WMS disk storage systems are functionally competitive against other established vendors' midrange disk storage offerings and have earned a reputation for being reliable." (January 2008)
MarketScope for High-End Enterprise Disk Arrays, 2007 "EMC remains behind the competition in terms of delivering feature functionality, which Gartner considers to be important in this segment. Even though support for a thin-provisioning implementation was announced for the DMX-4, it is not expected until the 1Q08 time frame, leaving EMC behind the technology curve relative to some of its competitors." (August 2007)
HDS, HP and Sun Up the Ante for High-End Storage "Hitachi brings innovation to the high-end storage market with its next-generation USP V. The systems couple virtualization with new thin-provisioning capabilities. Gartner expects that the financial, operational and environmental benefits of thin provisioning will make it a must-have feature by 2012. The USP V, along with its HP and Sun counterparts—XP24000 and 9990V—combine thin provisioning, space-efficient point-in-time copies, and virtualization in a highly scalable storage system that is operationally and financially appealing."
