The Dell PowerEdge Expandable RAID Controller 3 (PERC 3) PCI card is a high-performance, intelligent peripheral component interconnect (PCI)-to-SCSI host adapter with RAID control capabilities. The RAID controller provides system availability, high performance, and fault-tolerant disk subsystem management and is an ideal RAID solution with Dell PowerEdge systems. It offers a cost-effective way to implement RAID in a server.
Throughput on each SCSI channel can be as high as 160 MB/sec. PERC 3 supports both an LVD SCSI bus and a single-ended SCSI bus. PERC 3 is a high-performance, intelligent PCI-to-SCSI host adapter with RAID control capabilities. With LVD, you can use cables up to 12 meters long. PERC 3 requires no special motherboard PCI expansion slot.
