In all cases, there is at least I'm setting up a very similar system here, using DL360s. But, I'm using MSA-30's instead of local disks. > 256MB of cache on the controller and the BBWC is installed and > write-cache enabled. Drive-level cache is disabled of course. By write-cache enabled, do you mean enabled through the controller configuration? or in DRBD? Same question for drive-level cache.

I'm seeing 100MB/s during complete syncs over bonded gig-e links, so I'm hoping for a little better performance. Thanks, Justin
