There are no official numbers, we (the ECM MVPs) have been asking for years, but so far nothing...
These numbers simply comes from my own testing at various customers... and even though they are far from exact, they should give a rough estimate. Shorthand, when you see a site server starting to perform sluggish, to take several minutes to generate a policy, or long time to process incoming data, long time to evaluate collections, die because of summarizations kicking in etc... I immediately suspect disk IO (even though it can be of other reasons too). / Johan From: [email protected] [mailto:[email protected]] On Behalf Of Roland Janus Sent: den 22 oktober 2013 16:32 To: [email protected] Subject: RE: [mssms] SQLIO tests values? Still a couple of questions while the file is created :) Where you get the IOPS numbers from? They may indicate good and bad SAN, but what CM likely needs is just good enough performance (for either disk layout and I was going with the same approach idea depending on performance). So far the only number ever mentioned (afaik) was 5000 IOPS at lasts year MMS and that is certainly not official and way below what you have. -R From: Roland Janus [mailto:[email protected]] Sent: Dienstag, 22.

I'm testing our SAN currently and while I get like ridiculous good numbers for reading (6 number figures IOPS and 1GB/s) it is a different story for writing. But I have no idea if those tests are valid :) Anyone having some advice on good parameters to test with? -R
