So do I need a SAS HBA controller that supports IT firmware
if I'm going to plug into HP D2600 for an example ?

Or does the controller on the disk box advertise all the drives as per-disk ?


Sorry about my little knowledge.

Thanks !

Yes - LSI SAS 9200-8e is probably the one. Basically you want one with a 
chipset supported by the mpt_sas driver. 'man mpt_sas' says these are the LSI 
SAS200x/2108 chips.

The only thing I'd say about the DL360G7 is that IIRC there are only two PCIe 
slots so if you want more HBAs, or more NICs (it has 4 on the motherboard - bnx 
driver), you're a bit constrained.

Yes.
