Best Raid1 configuration for ESXi System
Posted on 2011-02-18
I have a server i'm converting from RAID5 into RAID1 for performance benefits.
The RAID card is an Intel SRCSASLS4L (HW Raid) and I have connected 3x SAS 10,000K drives.
I'll be running 2 in RAID1 and another as a JBOD for nonessential VM's.
The configuration questions I'm after are: (left is default)
Strip Size: 64k - 1024K
Read Policy: Normal, Adaptive, Ahead
Write Policy: WThru, WBack
WrThru for BAD BBU (ticked?)
IO Policy: Direct, Cached
Disk Change Policy: No Change, Enable, Disable
Disable BGI: No, Yes
