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_granularity. P17 and P18 appear to work fine and report correct values for discard_granularity. -Kurt -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
