2 different RAID controller

[Hank C]

is it possible to put both LSI 9361 and LSI 9211 RAID controller in a single system?

In general, yes. You can put as many as you want since they all have unique addressed so you can interact with each directly. In the managers, you will see each listed separately.

Chuck is correct.

thx

I actually had a screenshot handy from home, a 9271 and a m1015/9211.

Yes, as others have said, but make sure that you have the right LSI firmware. At a minimum the card that loads its BIOS first needs to have a firmware that supports both cards. Make it simple and just update the firmware on both cards to be the same version, preferably of course the latest version. With that done you probably won't have any problems at all. If you do, it's probably because your motherboard has run out of BIOS space. Disable the BIOS on one of the cards to fix this. I have run as many as 15 LSI SAS controllers in one server using this technique.

Because you need a way to run 1920 HDDs in the system... holy cow! That's a lot of cards.

Expanders not able to match the IO in your DB?

Exactly! In real-world analytics queries, 1.4-2GB/s per PCIe2 card is about all you get. If you need 20,000mb/s, well then keep adding cards! Oddly, most servers that I tested were not able to scale their IO to this level, but I eventually found some that worked.
