Sun sold its own storage systems to complement its system offerings; it has also made several storage-related acquisitions. On June 2, 2005, Sun announced it would purchase Storage Technology Corporation (StorageTek) for US$4.1 billion in cash, or $37.00 per share, a deal completed in August 2005.
In 2006, Sun introduced the Sun StorageTek 5800 System, the first application-aware programmable storage solution. In 2008, Sun contributed the source code of the StorageTek 5800 System under the BSD license.
Sun announced the Sun Open Storage platform in 2008 built with open source technologies. In late 2008 Sun announced the Sun Storage 7000 Unified Storage systems (codenamed Amber Road). Transparent placement of data in the systems' solid-state drives (SSD) and conventional hard drives was managed by ZFS to take advantage of the speed of SSDs and the economy of conventional hard disks.
Other storage products included Sun Fire X4500 storage server and SAM-QFS filesystem and storage management software.
