These are 8-port HBAs using the LSI1068 chipset, supported by the mpt(4) driver. Support 3 Gpbs SATA/SAS, using multi-lane cables (2 connectors on the card, each connector supports 4 SATA ports), hot-plug, hot-swap. These are UIO cards, so the bracket that comes with it doesn't work with normal cases (the bracket is on the wrong side of the card; they're made for SuperMicro's UIO-based motherboards). However, these are normal PCIe cards and work in any PCIe slot. You either have to remove the bracket, or you can purchase separate brackets online. These cards are recommended on the zfs-discuss mailing list. They are only ~$120 CDN at places like cdw.ca and newegg.ca. -- Freddie Cash fjwcash@gmail.com
