Xpenology and HP SAS EXPANDER - 487738-001


Recommended Posts

I have a supermicro server (MBD-X11SCA-FO) for my HomeLab with a LSI 9110-8i (IT mode) and a HP SAS EXPANDER - 487738-001

I have for the moment 8 Drives.

At the boot all the drives are detected but in the Xpenology (DSM 6.2.3-25426 Update 2) only 4 drives detected. I try to move to another connector, change the cable but it's the same

I don't know what to do to solve the problem ? What's going on ?

Not sure how SAS works out exactly but non-Synology branded hardware SATA port multipliers are not supported.


Looking at the card and specification, there is some sort of SAS multiplexing going on, so it may not work for this application.
