IBM Storwize

[2] Storwize is based on the same software as IBM SAN Volume Controller (SVC).

[3] Сollateral lines: The Storwize family offers several members:[4] Each of the above family members run software that is based on a common source codebase, although each has a type specific downloadable package.

As of November 2016, available Storwize media sizes include 2.5" flash SSDs with up to 15.36 TB capacity and 3.5" Nearline-HDDs with up to 10 TB capacity, available for Storwize 5000, 7000 and SAN Volume Controller native attach.

IBM Storwize Easy Tier will automatically manage and continually optimize data placement in mixed pools of nearline disks / standard disks / read-intensive Flash and enterprise-grade Flash SSDs, including from virtualized devices.
