Had lots of problems using my IBM BR10i and Dell SAS 5I\/r controllers; performance under ESXi 5 was terrible.
\nJust 3.5 MB\/s on write. Under Linux, write performance was around 110-120 MB\/s. So WTF ?<\/p>\n

I thought that all this was needed (disable Interrupt Routing):<\/p>\n

# esxcli system settings kernel list -o iovDisableIR
\n# esxcfg-advcfg -k TRUE iovDisableIR (just the above command wasn't enough)
\n# auto-backup.sh
\n# auto-backup.sh (yes, twice!)
\n# reboot<\/code><\/p>\n

Check:<\/p>\n

# esxcfg-advcfg -j iovDisableIR\u00e2\u20ac\u00a8# esxcli system settings kernel list -o iovDisableIR\u00e2\u20ac\u00a8<\/code><\/p>\n

But in the end, this wasn’t it. Seems that LSI1068E based controllers disable all disk caching built into the drives by default.<\/p>\n

If the server has battery backup you can enable basic drive caching on the Logical Volumes without risk (or, without a battery, WITH risk). <\/p>\n

Goto www.LSI.com (The controller is made by LSI) and download and install MegaRAID Storage Manager. In short, install the VIB on your ESXi machine, the Manager on a Windows or Linux machine, sync their host names and enable all ports on the ESXi firewall for incoming TCP traffic.<\/p>\n

Highlight the Virtual Raid Volume, right click, properties. Enable Cache and save. You have to do this on every logical raid volume.<\/p>\n

Your performance difference is incredible.<\/p>\n

And I just lost a day of looking for the solution. Crap.<\/p>\n
