SASGRID Could we replace IBM GPFS with GlusterFS

[Bhmanyam]

We have storage of about 150TB and planning to move from GPFS commercial to GlusterFS, Has any one implemented switching GPFS with any other shared filesystem on Linux servers?

IBM Spectrum Scale (GPFS) is a very mature, robust and performant shared file system.   Which means it has a high price tag.  

GlusterFS is a simpler, less performant shared file system.   And has a lesser price tag.  

It is said in the field of shared file systems that "you get what you paid for".   All kidding aside, please make sure all the features (backup, snapshot, security, ...) that you use with GPFS are available in GlustreFS.

We're planning to install SAS Grid on Oracle Linux on premise (not cloud) and migrate from current SAS from RHEL which has GPFS storage of 150TB and also planning to move away from GPFS to open-source clustered file system, any recommendations in that area? I'm seeing Luster is good option but seems support isn't promising for oracle linux OS. OCFS2 seems oracle Linux cluster filesystem, just want to check if SAS storage can be supported on OCFS2? GlusterFS is supported on oracle Linux but upon reading performance seems lackluster when compared to GPFS.

Hello @Bhmanyam 
With oracle Linux one would expect good OS level support for OCFS2. The following article has a good comparison.

IMHO the choice of   OS (oracle Linux Vs RHEL) is a factor to be considered in your selection.
