Model Description |
|
| |
P150C is the iSCSI-SATA RAID controller built around Qsan innovative RAID/iSCSI stack. With 2 Gigabit Ethernet ports connected to the host, either working independently, trunking, or MPIO together, Qsan lab data shows up to 45,000 IOPS. Running against multiple hosts with sufficient CPU power, P150C can achieve up to 300MB/sec in full-duplex. The outstanding performance is produced by not only the highly-optimized Qsan stack but also strong computing power offered by Intel IOP341. P150C supports SATAI/SATAII drives. It requires customized backplanes for customers interested in design-in to existing chassis. |
