Installing HPE Smart Array P408i-a SR Gen10 Controller

jscooper22 — Thu, 14 Apr 2022 00:33:01 GMT

I'm setting up a DL380G10 for our company. It has a HPE Smart Array P408i-a SR Gen10 Controller which i installed per the documentation; it powers up and the Array Admininistrator sees it. BUT, it does not see any physical drives (I have three SSDs).

I just summitted a support case about this, but a (I hate to say stupid but maybe a stupid) question just occured to me: Nowhere in the installation instructions does is explictitely say I need to connect cables to the controller. I figured the circuitry did what it had to do to make the controller talk to the drives. I thought the controller talked to the mainboard and did what it had to do through the cables connected from the mainboard to the drives.

Am I wrong about this? Should I disconnected the cables from the mainboard (that connect to the drives), and connect them directly to the controller?

Thanks,

Jeff

Hi,

yes you should connect the cables from the hdd backplane to the controller.

Hi, this controller has 8 internal lanes, so i beleive the backplane has to be connected directly to the controller

in the attached image i can see this controller has the connections

Hello Richard,

Yes the backplane needs to be connected directly with the controller ports using a SAS Cable.

Depending upon the backplane being used, please refer to the below link for cable information

https://support.hpe.com/hpesc/public/docDisplay?docId=a00019109en_us&page=GUID-C42E3178-9C64-49C8-9ABD-83A80164A6FF.html

Also if you need to connect more than 8 drives to the controller, then you would need the SAS expander.

Please refer to the below link for SAS expander Cabling

Hope the above information answers your query..

Thanks,
