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

I currently have 2 x Intel X25-E (32 GB) as dedicated slogs and 1 x
Intel X25-M (80 GB) for the L2ARC behind a PERC 6/i on my Dell R905
testbox.
So far there have been no problems with them.
Really?
Now you have my interest.
Two questions, did you get the X25 from Dell? Are you using it with a
hot-swap carrier?
Knowing that these will work would be great news.
