You've come to the right place.

I'm a little late to the party but the SAM-QFS OpenSolaris project went live this month. Nice job Ted and Cindy!

Shared QFS and SAM (Storage Archive Manager) have quite a legacy in big data and HPC environments. These products are used in interesting configurations to stream video, archive bank data, store lots and lots of Homeland-security type of data... the list is pretty lengthy. SAM-QFS is quite a nice fit with Sun's overall storage software portfolio and now it's starting down the path of open communities and collaboration.

If you want to test drive Sun's SAM-QFS commercial binary, you can download SAM and Shared QFS for free. For more detailed product information check out the engineering team's blog.

The first bit of source code to be opened is libsam, a library/API that allows you to manage data in a samfs file system from an application. With libsam you can...

• Archive - copying a file from samfs to archive media

• Release - freeing up the disk cache by letting go of archived files that no longer meet on-disk retention criteria

• Stage - bringing a file back from archive media to the disk cache

• Recycle - removing redundant copies or older versions of files from archive media
