We've recently noticed multiple Dell servers with PERC 6 RAID controllers that appear to have had a default setting where no READ cache was enabled. Changing this to Adaptive Read yielded an average 20% improvement in sequential read performance.
I guess one has to be at the console and start some firmware / keystroke combo to get into that option? I am looking forward to reboot the server and see. Normally I don't like to do that at all.
Dell's Open Manage Server Administrator tool, if installed, will let you check and change this from Windows.
Or if you have Drac or iDrac cards.

Including if one has Windows installed virtually?
Looks like it has to be installed within the Hypervisor...

Granted just checking a raid setting would only require one reboot - installing OM takes a few it looks like, but then you have it accessibly moving forward. Better to just get iDracs on any new boxen - you may even be able to get it for an existing server.
So.. remembering the username and password combination for your iDRAC is somewhere on the list of important things then, I take it.
The only hint I left myself is that it 's not root/calvin and that I have forgotten it before.
What...you're not using the Vortex password manager by Nick's buddy?

Hah! Nah, my password manager is physically mounted on a stick just above my shoulders. Found my password written on the bottom of my virtual keyboard ;)
BUT, not seeing where this setting is in the iDRAC yet.
Hrmm maybe the idrac doesn't cover raid, I thought it did. I'll take a look later this week when the list at my desk goes under 5 people.
