Move over St. Patrick, March 17th is officially SAM's day.

Its hard to believe it was just about a year ago when Sun announced it would open source all Storage Software IP. Since then significant contributions have been made to the OpenSolaris storage community. These include a CIFS server, Comstar, and others can be found here: http://opensolaris.org/os/community/storage/

No single contribution has been so eagerly anticipated or misunderstood as the effort to open source SAM and QFS. So for me this is a major milestone for all those involved in making this a reality. Thanks to the dedicated persistence of the SAMQFS engineering team as this was a significant drain on resources that could have been deployed developing new features .

Unlike other OpenSolaris projects, SAM and QFS are software products marketed and sold by Sun and its partners since 2001. The software has many commercial users in medical, media & entertainment, government, manufacturing, financial services, education that benefit from the services this software provides.

SAM or the Storage Archive Manager software is key to Sun's archive strategy today. A few weeks ago, Sun made some noise about new archive systems including a customer ready system that embeds this SAM and QFS in a tiered storage architecture. Way ahead of its time in the mid 90's, SAM still provides users with an innovative way to transparently or virtually manage data across different tiers of storage including tape differentiating it from 'disk' only tiered solutions.

QFS provides users with a shared file system that's ideal for intensive environments. Commercial users with high performance computing requirements will benefit from the seamless transfer between the compute and storage nodes and long term data retention with SAM.

Together this dynamic duo are used to deliver an amazing number of storage solutions that leverage commodity server and storage hardware and help drive Solaris adoption in the data center.

So what exactly does this mean for Sun?
First it shows that we're committed to being open. It's a strategy that affects they way we work, think about, and market technologies and products we offer. As a result, Sun is changing the storage marketplace. Unlike other vendors, Sun's storage software stack is open and with these major source contributions, Solaris gets even more interesting as a storage OS on which to build storage systems or appliances.

What does this mean for the Storage Community?
Storage developers and deployers interested in these technologies will find more than access to the source code when they participate in the OpenSolaris storage community for this software. You can dialog directly with the SAM/QFS engineering team as they develop new features. As a member of the community you can influence the direction for this software only when you participate so join the OpenSolaris storage community today!

What does this mean for Sun customers?
Sun customers will benefit from more choice, value and innovation that comes from open software and open standards. For commercial users of this software, a binary version of the software is available with a Sun standard software license, RTUs and Sun services for a FEE.
