Hi Zach, VMware is covered via Pass-through Raw Device Mapping (RDM) with physical compatibility mode if you want direct disk access inside the VM. Otherwise works as a "normal" GPFS client
Go to: "Table 28. VMware support matrix" @ http://www-01.ibm.com/support/knowledgecenter/STXKQY/gpfsclustersfaq.html Have a client using this in production with x86 RHEL running on top of VMware ... it works well. They use RDM since the VMs do have disk access directly.

Sent by: [email protected] Hello Everyone, Medium-time user of GPFS, MySQL, PostgreSQL, etc here.. Decent sized system in production, hundreds of nodes, lots of tuning etc. Not a newb. :) Looking for opinions on running database engines backed by GPFS. Has anyone run any backed by GPFS and what did you think about it? I realize there are tuning guides and guide-lines for running different DBs on different file systems, but there seems to be a lack of best-practices for doing so on GPFS. For example, usually you don't run DBs backed by NFS due to locking, cacheing etc.. You can tune those out with sync, hard, etc, but, still the best practice is to use a local file system. As GPFS is hybrid, and used for many apps that do have hard requirements such as Cinder block storage, science apps, etc, and has proper byte-level locking.. it seems like it would be semi-equal to a lock file system. Does anyone have any opinions, experiences, or recommendations for running DBs backed by GPFS? Also will accept horror stories, gotcha's, and "dont do it's". :) On that same note... How about VMware? Obviously I guess really the only way would be via NFS export.. which cNFS was .. not the best at (my opinion). Maybe Protocol Servers are better? Maybe also a "don't do it"?
