RE: Cluster file systems versus raw devices in Oracle RAC

Have you seen/implemented EFSCG for Oracle databases ?    

Ahhhh...but of course. Me testing with Oracle? :) Oracle is examining our OSCP testing results now. Things look good. I'll be presenting a Proof of Concept paper at RMOUG Training days in Feb.  

Let's just say that a really busy table (or write intesive anything) in any other OSCP NAS out there can easily become the bottleneck. Instead of getting another filer, pulling some of the hot data out and plunking it into the new filer, you just add a NAS head in this architecture and serve up the same files via that new head along with whatever
heads were previously serving up those files (scalability without replication)
...data stays in place. Oh, also, I can power off an active NAS head right
our from underneath an PQO index creation and nothing skips a beat...now that is real
HiAv storage for RAC. I can power off the NAS head that is serving up the
CRS files too without any impact to Oracle.  

I would go into the particulars of why EFS.CG is good for Oracle deployments, but there is a dangerously high percentage of list participants here that view anything other than "the way we have always done it" as some sort of personal insult.         Received on Fri Dec 30 2005 - 19:32:03 CST
