Sure - the shelves are SuperMicro systems running Ubuntu 10.10. There are 36 Seagate Constellation ES 2TB drives connected to 5 LSI 8888ELP controllers. The drives are arranged in four groups of eight drives in RAID6 and one group of four drives in RAID5. These five RAID groups are set up as iSCSI targets on the Ubuntu system. There are two of these SuperMicro shelves. So, there are ten LUNs available by iSCSI to OpenIndiana. The tank is created with one VDEV for the ten LUNs.
