Sean Rector, MCSE -----Original Message----- From: Ben Scott [mailto:mailvor...@gmail.com] Sent: Friday, May 29, 2009 1:31 PM To: MS-Exchange Admin Issues Subject: Single Instance Storage ratio survey Hi all, A thread on nt-sysadmin has got me wondering. Just how much do people actually benefit from SIS (Single Instance Storage) in Exchange? Would people be willing to share their SIS ratio from their Exchange server(s)? Approximations are fine. For multi-server organizations, an average or just picking a server at random would still inform. I'll start: SIS ratio = 5.6 You can discover the SIS ratio by: 1. Open Performance Monitor (PERFMON.EXE) 2. Select "System Monitor" on the left 3. Right-click the graph on the right, and pick "Add Counters" 4. For "Performance Object", select "MSExchangeIS Mailbox" (or similar) 5. Select the "Single Instance Ratio" counter in the list on the left 6. Select the "_ Total" instance in the list on the right 7. Click "Add" 8. If needed, select the resulting counter in the list at the bottom of the graph 9. Look at the "Last" value reported for that counter -- Ben ~ Ninja Email Security with Cloudmark Spam Engine Gets Image Spam ~ ~ http://www.sunbeltsoftware.com/Ninja ~ Virginia Opera's 35th Anniversary Season The One You Love Celebrate with a 2009-2010 Subscription: La Boh?me, The Daughter of the Regiment, Don Giovanni and Porgy and BessSM Visit us online at www.vaopera.org or call 1-866-OPERA-VA This e-mail and any attached files are confidential and intended solely for the intended recipient(s).
