PE RC 3/ DC and PE RC 3/DC L Fe atures 69PCI Bridge/CPUBoth PERC 3/DC and PERC 3/DCL use the Intel i960RN PCI bridge withan embedded i960RN RISC processor running at 100 MHz. The RN bridgehandles data transfers between the primary (host) PCI bus, the secondaryPCI bus, cache memory, and the SCSI bus. The DMA controller supportschaining and unaligned data transfers. The embedded i960JN CPU directsall controller functions, including command processing, SCSI bus transfers,RAID processing, drive rebuilding, cache management, and error recovery.Cache configuration 64 MB or 128 MB DIMMFirmware 1 MB × 8 flash ROMNonvolatile random accessmemory (RAM)32 KB × 8 for storing RAID configurationOperating voltage 5 V, 3.3 VSCSI controller Two SCSI controllers for 160M and Wide support.SCSI data transfer rate Up to 160 MB/s per channelSCSI bus LVD or single-endedSCSI termination ActiveTermination disable Automatic through cable and device detectionDevices per SCSI channel Up to 15 wide or seven narrow SCSI devices.SCSI device types Synchronous or asynchronous.RAID levels supported 0, 1, 5, 10, and 50SCSI connectors Two 68-pin internal high-density connectors for 16-bit SCSI devices.
