I have an HP ML110 and inside there are two SAS ports on the mobo. Port 1 is being utilized by the plug that came with the server and it serves four different SAS drives (see pic).
There is a second SAS Port that is open and ready for another SAS connector to service 4 more drives. The tag on the current connector says "HPE Spare PN: 791719-001"
When I search for an additional spare SAS connector I get $300+. Is that correct? Certainly there's a cheaper alternative to expanding from 4 drives to 8?
