Using HP Smart Array p400 hardware RAID card on a consumer motherboard

Trying out some enterprise-level devices on a home desktop PC, just for fun. It seems to be possible to build an inexpensive home server using this type of configuration. The used SAS drives and controllers are very cheap on ebay etc, also SATA drives can be used. Battery-backed cache, which this hardware-RAID card has, would make the write speed "skyrocket" in some occasions. So look for controllers with the battery pack included. Onboard SATA and software RAID functions on most boards are also good options for many applications. This system&total power consumption, with an AMD Athlon 4450e processor and Quadro NVS 295(geforce 8400) varies between 85 and 105 watts. So it is not the most effective system, but not very power hungry either. Latest 7200rpm SATA drives would be possibly the best option for home use for capacity, performance, noise and power consumption. HP Smart start bootable CD can be used to configure the P400 card, enabling its options and setting up arrays.
