4.9 MegaRAID SCSI 320-0 Specifications
Table 4.6 lists the specifications for the SCSI 320-0.
4.9.1 PCI Bridge/CPU
MegaRAID SCSI 320-0 uses the Intel i960RM PCI bridge with an
embedded 80960JX RISC processor running at 66 MHz. The RM bridge
handles data transfers between the primary (host) PCI bus, the
secondary PCI bus, cache memory, and the SCSI bus. The DMA
controller supports chaining and unaligned data transfers. The
embedded 80960JX CPU directs all controller functions, including
command processing, SCSI bus transfers, RAID processing, drive
rebuilding, cache management, and error recovery.
