New SAM-QFS patch released for download
By Ted Pogue on Dec 12, 2007
We recently released the third 4.6 patch (4.6-03). A few items that I think are exciting support additions in this patch, on top of the usual bug fixes.
1) 256 node support for Fibre Channel.
\* This is part of our continuing effort to increase the scalability of Shared QFS. This should be welcome news for those customers already running 128 nodes and looking to increase node count. It also enhances Sun's HPC file system offering for small to mid size customers.
2) New tape drive and library qualifications.
\* The Sony CSM-20S library has been qualified for use with Sun StorageTek SAM-QFS 4.6 Patch 03. The device type is 'cs'. The import command in SAM for CSM-20S library imports one tape at a time.
\* The IBM LTO4 tape drive has been qualified for use with Sun StorageTek SAM-QFS 4.6 Patch 03. The device type is 'li'. Although no changes are required in /kernel/drv/st.conf for SAM support of the IBM LTO4 drive, the latest st patch is required.
\* The Quantum DLT-S4 tape drive has been qualified for use with Sun StorageTek SAM 4.6 Patch 03. The device type is 'lt'. Although no changes are required in /kernel/drv/st.conf for SAM support of the DLT-S4 drive, the latest st patch is required.
3) New server architecture support \* Intel EM64T 64 bit architecture servers are supported with Shared QFS
Also, take a look at our new Wiki for more information on 4.6. It provides a growing wealth of technical information on SAM-QFS releases, including a patch download link, documentation, a growing faq, and more. Here is the link to the wiki:
Lastly, we are still forging ahead with our open source plan. We've started a discussion alias "firstname.lastname@example.org" and added the source for sdu, sls, sfind, and star to the existing Libsam code. Expect more code in the coming months. I also encourage you to join the discussion alias and become part of the community. Here is the link to the open source page
'til next time, Ted
