We've purchased a HP Proliant DL120 G7, which has an onboard Smart Array B110i controller. In the server, we've bought 4 x Hitachi 4Tb SATA drives, mounted them in HP drive caddies and installed them in the server. However, the B110i controller only shows the drives as 1.8Tb:
If we disable the B110i and use the AHCI controller instead, all 4Tb per drive is available. We'd really like to use the B110i if possible; does anyone know why the full drive capacity isn't available? According to the QuickSpecs, 4Tb drives are supported (and yes, I realise these aren't HP drives).
