Highpoint RocketRAID 2322
Measuring just over 12cm in length and 8.5cm in height, the card is short but high, in fact it's larger than the half height form factor that Highpoint normally use, making it a definite no-no for servers that only support half height expansion cards. With these measurements, it's clear this card is more the workstation or desktop user's best friend.
The front of the card houses the Mini SAS external connectors, the Marvell controller chip, an Intel System Management and hardware RAID controller chip as well as the Single RAID links and the Highpoint 601 hot swap chip.
The back of the card is surprisingly bare with just the voltage regulators on the real estate, normally Highpoint is packing a lot on the back - we guess the full height PCI setup affords them more room.
The interface to the board is a PCI Express x4 connector. This card will fit into universal PCI Express slots as well as x8 and x16 slots. We used our Gigabyte P965-DQ6 motherboard and placed the controller in the second PCI Express x16 slot, which is normally reserved for VGA cards.
On the PCI expansion bracket we see the Mini SAS connectors which the card uses. These ports support four drives each. Thanks to the Marvell chipset, you can RAID the external enclosures all together, that's 8 drives in RAID mode - outside of your case! If you use a second 2322 card with the single RAID link mode, you can have a 16 drive RAID array and some seriously kick ass performance or redundancy or both.
