This isn't up to date, and doesn't specifically discuss performance, but it gives you some info regarding the Intel technology and the population of the channels/banks:

Initially we were going with 96GB of RAM but I got an comparison quote from Dell and they said “The memory configuration that was given (8 * 16 GB) is not optimal for a VM Host as the modules are not balanced across all the DIMMS with Intel the memory must be populated in sets of 3 Chips to evenly balance across the 3 Channels otherwise you may lose up to 33% of performance” and they quoted me 192 GB of RAM per server. (12 * 16 GB). My HP reseller came back and said that max available for the Host is 144 GB and re-quoted me 18 * 8 GB modules. Tried to do some googeling but could not find anything relevant, anyone have any insights into this? -- Stefan Jafs ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected] with the body: unsubscribe ntsysadmin ----------------------------------------- This message, and any attachments to it, may contain information that is privileged, confidential, and exempt from disclosure under applicable law.
