<html><body><p>Hi Zach,<br><br>VMware is covered via Pass-through Raw Device Mapping (RDM) with physical compatibility mode if you want direct disk access inside the VM.<br>Otherwise works as a "normal" GPFS client<br><br>Go to: "Table 28. VMware support matrix" @ <a href="http://www-01.ibm.com/support/knowledgecenter/STXKQY/gpfsclustersfaq.html">http://www-01.ibm.com/support/knowledgecenter/STXKQY/gpfsclustersfaq.html</a> <br><br>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.<br><br><font size="2" face="Arial">Mit freundlichen Grüßen / Sincerely</font><br><br><b><font face="Arial">Christoph Krafft</font></b><br><br><font size="2" color="#0055AA" face="Arial">Client Technical Specialist - Power Systems, IBM Systems</font><br><font size="2" color="#0055AA" face="Arial">Certified IT Specialist @ The Open Group </font><table border="0" cellspacing="0" cellpadding="0"><tr valign="top"><td class="small_font" width="800" colspan="4" valign="middle"><hr width="100%" size="2" align="left" style="color:#696969; "></td></tr>

Decent sized<br>system in production, hundreds of nodes, lots of tuning etc. Not a<br>newb. :)<br>Looking for opinions on running database engines backed by GPFS.<br>Has anyone run any backed by GPFS and what did you think about it?<br><br>I realize there are tuning guides and guide-lines for running<br>different DBs on different file systems, but there seems to be a lack<br>of best-practices for doing so on GPFS.<br><br>For example, usually you don't run DBs backed by NFS due to locking,<br>cacheing etc.. You can tune those out with sync, hard, etc, but, still<br>the best practice is to use a local file system.<br>As GPFS is hybrid, and used for many apps that do have hard<br>requirements such as Cinder block storage, science apps, etc, and has<br>proper byte-level locking.. it seems like it would be semi-equal to a<br>lock file system.<br><br>Does anyone have any opinions, experiences, or recommendations for<br>running DBs backed by GPFS?<br>Also will accept horror stories, gotcha's, and "dont do it's". :)<br><br>On that same note...<br>How about VMware?<br>Obviously I guess really the only way would be via NFS export.. which<br>cNFS was .. not the best at (my opinion). Maybe Protocol Servers are<br>better? Maybe also a "don't do it"?<br><br>Thanks,<br>-Zach<br><br><br>-- <br>Zach Giles<br>zgiles@gmail.com<br>_______________________________________________<br>gpfsug-discuss mailing list<br>gpfsug-discuss at gpfsug.org<br></tt><tt><a href="http://gpfsug.org/mailman/listinfo/gpfsug-discuss">http://gpfsug.org/mailman/listinfo/gpfsug-discuss</a></tt><tt><br><br></tt><br><BR>
