SSD RAID Setup
Posted on 2011-09-09
I'm in the process of looking to swap out a bunch of SSD's that run my database server (32 drives total). I'm swapping them out for more reliable drives (I've had 2 fail in under 6 months). I'll be creating 6 volumes of differing sizes, and in RAID configurations of 0,1 and 10 (mostly 10).
So, I've read that it's best to let Windows disk manager configure the volumes vs. using my RAID controller to setup the arrays. Is this true? I've never used the disk manager to setup spans or stripped volumes, always used the controller cards.
Would the advantage be that since the drives aren't being managed by the controller is that Windows will be able to use TRIM on the volume? If so, is that still the case even though I have to setup the drives on the controller to Post? I'm unable to directly attach the drives to the Mobo's ports due to the fact that we have so many drives (I have two LSI controller cards, one that runs the 8 drives on my backplane, and one that runs my 24 bay enclosure)
