Sun Open Storage

Sun Open Storage was an open source computer data storage platform developed by Sun Microsystems. Sun Open Storage was advertised as avoiding vendor lock-in.


In 2006, under the direction of then CEO Jonathan I. Schwartz, Sun began releasing their software as open source. This was seen by many[according to whom?] as a way to compete with the rise of competing open source platforms, primarily Linux.

The move to create storage products based on software personalities, running on standard hardware are also part of a broader move within the system and storage industries. Companies including Dell, EMC, HP, IBM, NetApp and numerous smaller vendors all have been moving towards storage products based upon standard server hardware and customized software.

Sun's Open Storage products are a combination of their server technologies and customized software. Many of the features of these products reside within the core Solaris. Additional storage specific features have been added to create a complete integrated product. Core features provided by Solaris include the operating environment, the ZFS file-system, an analytics tool based on Dtrace, the Network File System (NFS) and CIFS protocol interfaces and other core features.

Statements by Sun around their Open Storage products indicated that products based on common hardware and open source Solaris, would remove vendor lock-in for customers.[citation needed]

In 2008 Sun estimated that open storage products and related services would gain 12 percent of the storage market by 2011.[1] Storage solutions from other vendors are closed systems, in which all the components must come from the vendor. However, by around July 2010, after Oracle had acquired Sun, it used the "Unified Storage" brand instead of "OpenStorage".[2]


At the storage protocol layer, OpenSolaris supported SCSI, iSCSI, iSNS, Fibre Channel, FCoE, InfiniBand, RDMA, Object storage device, and SAS.
