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 400mhz intel iop321 processor offers a maximum throughput up to 1.6 Gb per second and also supports up to 512mb 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. Features: intel iop321 i/o processor, two-channel ultra320 scsi with support for up to 30 drives, 64-bit/133mhz pci-x interface, support for raid levels 0, 1, 5, 10, 50, and jbod, 128mb dimm included (supports 32mb-512mb of pc1600 ecc ddr sdram), new software suite: intel raid bios console, intel raid web console, intel raid command tool, intel raid diagnostics, intel raid flash utilities, background initialization and instant availability, online capacity expansion and raid-level migration, remote event monitoring via snmp, saf-te-compliant, microsoft server clustering support, optional battery-backup unit. Specifications: hardware processor intel iop321 i/o processor: based on intel xscale technology, with hardware xor. Memory supports 32mb-512mb of pc1600 ecc ddr sdram (ships with 128mb dimm installed). Pci 64-bit/133mhz pci-x interface (pci 2.2 And pci-x 1.0 Compliant), 3.3V adapter, backward compatible to 33mhz and 66mhz. Scsi two-channel ultra320 scsi with support for up to 30 drives (15 per channel), each channel has one internal 68-pin connector (uhd lvd), and one external 68-pin connector (vhdc lvd). Form factor half-length, full-height pci: 175mm x 107mm (6.875 X 4.2). Status indicators audible alarm, leds. Software raid levels supported 0, 1, 5, 10, 50, and jbod. Scalability online raid-level migration and capacity expansion without reboot. Configuration flexibility variable data stripe size-configurable per array, configurable jbod enclosure support, support for non-hard-disk-drive scsi devices (for example, tape, cd-rom), and read/write controller and disk caching. Availability instant availability and background initialization, automatic rebuild with private (dedicated) or pooled (global) hot-fix (spare) drives, hot-plug drive support, and drive roaming.
