Re: LSI SAS2008 SATA TRIM not working

I can report that the Samsung 840 Pro *does* support trim on the LSI SAS2008. As suspected it supports deterministic read zeros after trim. One other thing to note, in my testing the P16 LSI firmware has broken trim support. P14 and P15 report incorrect values for /sys/block/sdX/queue/discard_gran

LSI SAS2008 SATA TRIM not working

2014-02-06 Thread Kurt Miller
Various sources indicate that LSI's SAS2008 controllers support TRIM when running their IT firmware (LSI [1] and this list [2]). However, I have not been able to get it working with Dell PERC H200 or H310 cross flashed into LSI IT firmware. Currently I'm testing with Samsung 840 EVO SATA SSDs. I ha
