controller when Dassault dispatched their professional services
onsite to help us migrate Enovia MatrixOne off Microstupid to
Solaris on X4250s.
Performance went to hell when they were uploading files and running
the indexer simultaniously.
I was able to duplicate by running bonnie++ on two separate ZFS
Swapped out the Adaptec for the LSI and we were back in the 21st
Looks like Adaptec has lost Larry Ellison and company's business
as the Adaptec controller is not an option for the X4270M2s AFAICT
from the Hardware Handbook on MOS.

Years ago I saw one that was a rebadged Adaptec.
The trick is to fetch Dell's Solaris or Unbreakable Linux drivers

the market that Thomas Kurian and company's ERP system can't
profit and that Larry Ellison has no interest.
- The "StorageTek SAS RAID External" controllers in our X4270s have boot
BIOS messages from Adaptec and use the aac driver, but you download
firmware and software from Intel.
They appear on the Intel site as OEM Storage Controllers.

go up to 6Gbps. Also, my understanding is that some chipsets can use
either mpt or mr_sas (!= mpt_sas) depending if their BIOS makes them do
RAID or not.
But all in all, LSI chipsets are very well supported at the driver
level, and the lsiutil tool works well.
The MSM tools from LSI are incredibly buggy, though, and will try hard
to break your system before failing to work. Luckily, they're difficult
to find on LSI's website. I think there's a version distributed by
Sun/Oracle, but I never tried that.
