there, dedicated slog device with NVRAM speed. It would be even
better to have a pair of SSDs behind the NVRAM, but it's hard to
find compatible SSDs for these controllers, Dell currently doesn't
even support SSDs in their RAID products :-(
Isn't the PERC 6/e just a re-branded LSI? LSI added SSD support
recently.
Yes, but the LSI support of SSDs is on later controllers.
Sure that's not just a firmware issue ?
My PERC 6/E seems to support SSD's :
# ./MegaCli -AdpAllInfo -a2 | grep -i ssd
Enable Copyback to SSD on SMART Error : No
Enable SSD Patrol Read : No
Allow SSD SAS/SATA Mix in VD : No
Allow HDD/SSD Mix in VD : No

So far there have been no problems with them.
