Solaris QFS as a shared file system for SAS GRID environment ?

BigSASFan — Wed, 21 Feb 2018 21:43:03 GMT

Hey guys,

There is not much information regarding SAS GRID servers on Solaris cluster. For example, which shared file systems are recommended for WORK / UTILLOC / permanent dataset libraries in a Solaris cluster? One SAS document mentions Solaris QFS, but does not give detailed evaluation or recommendation. If anyone has experience, please share your opinion.

Thanks in advance,

The best practices are to put SAS WORK and SAS UTILLOC on internal SSD drives to you SAS Grid compute nodes. You would use a local file system.

As I stated in another blog post you have done, Solaris QFS can be used for the shared file system with SAS Grid on Solaris. We have not done any testing recently with this shared file system, but it did work in the past. There was no specific tunings that had to be done.

If you are having issues with this shared file system, then you need to work with Oracle/Solaris support to determine what the issue is.
