For a server we have spec'd - HP Proliant DL370 G6 with a total of 3 SFF drive cages (up to 24 SFF drives total) - where would we use the SAS Expander vs. adding one or possibly two separate P410 Smart Array controllers?
Can each Drive Cage connect to a separate controller?
If yes, is cost the reason to use a SAS Expander vs. a separate P410 controller on each drive cage?
