Enabling Disk Write Cache on IP35

[ShadeZeRO]

Long story short.

I tried enabling Disk Write Cache on all my drives (though policies).
SATA drives set to AHCI
2 SAS Drives on Perc 5/i Set on RAID 0 --- > Flashed to LSI

Nothing seems to enable correctly.

Using the latest IP35
Any suggestions?

You cannot enable any caching except in the controller BIOS.
Enabling cache REQUIRES that a BBU be installed.

Are you referring to the Perc 5i's BBU (which I have ordered, should be here in a few days).

Edit: You were correct, I plugged my BBU in through USB and all my Non-SAS disks have write-caching now.
I'd assume, once my BBU for my Perc 5/i Card comes in a few days that'll be the same case.

Thanks!
