Can anyone else confirm that the Highpoint 4320 does indeed work with the expander? It says on the front page that it is confirmed working but jmmcc (who I have just quoted) was unable to get it to work.
I'm considering the purchase of the Highpoint 4320 + HP SAS Expander myself and I'd love some more yay or nay's on the compatibility before I pull the trigger.
I purchased the Highpoint 4322 just last week and its been running fine with my HP SAS Expander via the SFF-8088 port. The 4322 only has two external SFF-8088 SAS ports so I cannot test linking via the internal SFF-8087 ports.
