High-availability, high-capacity applications require a delicate blend of power and flexibility. Embedded systems, complex networking solutions, and other I/O-intensive applications demand a storage solution delivering generous throughput rates and data protection for high-availability server environments. That solution is the Intel RAID Controller SRCU42X, which offers dual-channel Ultra320 SCSI technology along with the advanced I/O processing technology of the Intel IOP321 I/O processor. This makes the RAID Controller SRCU42X one of the few RAID controllers in the industry to offer integrators the remarkably high throughput supported by a PCI-X interface as well as the performance, power efficiency, and flexibility of the Intel XScale technology. With its 133MHz PCI-X interface, the RAID Controller SRCU42X achieves up to 1 GB per second maximum throughput. Its 400 MHz Intel IOP321 processor offers a maximum throughput up to 1.6 GB per second and also supports up to 1 GB of PC1600 ECC DDR SDRAM. In addition, a new software suite based on PCI-X simplifies configuration, diagnostics, and firmware updates and enables integrators to offer a full set of RAID options at entry-level price points.
