Hello, been going crazy trying to figure this thing out… Ok I have a HP DL360 Gen10, It has two controller one onboard which is a SATA only and the 480.
The last two bays 9 & 10 I would like to use for two more SSD SAS drives 1.9 TB
I purchased and installed the LSI 9211-8i on one of the PCI slots on the server, and connected to the back plane removing one of the cables from the 480 controller controller.
I power up the server and seems the controller is detected but unknown state, I remove the cable and still in a unknown state. It seems to be in IT Mode according to the BIOS
Are you trying to connect a SAS controller to the backplane connector that was connected to PCIe? Yeah, there’s no way that’s ever going to work with a SAS2 controller, and from the labeling on your system I don’t think tri-mode/U.3 would work either (not that you’d want it to).
Judging by HPE’s docs, that backplane is probably the “10 SFF NVMe/SAS” [1] option. The last two bays are said to only support NVMe drives, much like what you see on the Dell R6515, for instance. So, by all indications, you have 10 U.2 bays, 8 of which are wired for SATA/SAS and PCIe, and two of which are only wired for PCIe (so that HPE can spare themselves the cost of a SAS expander for a measly two bays, something that was typical on high-end servers of the Xeon E5 generations).
We might be able to confirm this if you show us pictures of the whole backplane assembly and its labels.
Also, disconnect the SAS stuff from the PCIe connector on the backplane. It’s not likely that you’ll damage something, but it’s also not a great idea.
People who say LFF and SFF: Please stop your obnoxious nonsense. The only correct terms are 3.5" and 2.5". ↩︎
SAS expanders are expensive and it’s the 2020s. 99% of servers with more than 8 2.5" disks could probably use an NVMe drive or two. In fact, the SATA/SAS part could go away entirely with not much loss of value.
Yes, correct, I was reading up on it, and if I choose I can have 10 NVMe… For the mot part would most likely leave as is… and with the 7 2 TB drives create a RaidZ2 and call it a day. gives me around 8.x TB… for now is good.
Will take a look at that adapter incase I can just add and remove in the future…
