Does Intel RMS25LB (LSI2308) support TRIM in any mode?

[heathen]

Hello!

I'm wondering: does Intel RMS25LB support trim? Better in RAID but at least in pass-through mode? Can't find any info on that. Would like to use AH2000JF6GKIT and move to SSDs but without TRIM it can be tricky.

Thanks!

On modern enterprise SSDs TRIM is less useful. You're either writing hard to disks where TRIM is useful and therefore using enterprise SSDs or you're not writing much and TRIM is not useful but there is time for GC to kick in.

Yes, it will be used with enterprise SSDs, but can't be sure that GC works well on all of these kind of drives. And if TRIM/discard works in pass-through but doesn't in RAID mode - than I would go with dynamic RAID probably.

TRIM is supported by drives but triggered by OS. RAID controller drivers need to be able to pass TRIM command or its analog to drives. You will have to find out if drivers you run support TRIM.

Thanks for your answer.

The thing is that I don't currently have this configuration, and trying to predict problems (and, probably, change configuration a little if it's possible).

Yes HBA's ( 2308 in IT mode etc ) can passthrough TRIM to even conventional SSD's with no problems , but again, it still depends on driver/firmware versions. Older driver and firmware versions might not pass through.

Finally played a little with H2312JFFKR and AH2000JF6GKIT. Went with RAID1 for now. Also had a long lasts pleasure with trying to find any firmware for SAS controller (no any info about RMS25LB in the Internet at all except ark article! found firmware with Google and only because it was mentioned in readme as UEFI command file name) as well as with fixing "inaccessible boot device" error after WinServer 2012 R2 installation.
