The system starts with no extra cache memory and supports stripes and mirrors, but the review unit included the 256MB cache module that fits in a dedicated slot and adds support for RAID5. If you want the extra four drives you’ll need a second backplane, which is cabled to the spare SAS port. HP has also improved its RAID offerings since its old Smart Array P410 card has been replaced with an embedded P410i controller and a pair of four-port SAS interfaces on the motherboard.
HP takes first blood in the storage department, as the D元60 supports up to eight SFF hard disks – the R610 has room for six. Representing an entirely new architecture, they introduce Intel’s QPI (quick path interconnect) Hyper-Threading and Turbo Boost technologies. The D元60 supports Intel’s new 5500 Series “Nehalem” processors. Dell’s PowerEdge R610 bowled us over when we reviewed it, and since the D元60 G6 is its direct competitor it’s going to need something special to further impress.
