AMCC's PowerPC(R) 440SP Processor to Be Used in HP ProLiant Servers; 440SP Offers High Bandwidth, Low Power and RAID Support for Demanding Storage Applications.

SAN DIEGO -- Applied Micro Circuits Corp. (AMCC) (NASDAQ:AMCC) today announced that its PowerPC 440SP storage processor would be used in the new HP ProLiant P600 Serial Attached SCSI (SAS) controller. Chosen for its industry leading bandwidth, integration and RAID hardware support, the PowerPC 440SP provides the highest level of performance for demanding storage processing applications.

With a rich combination of features, the PowerPC 440SP processor is ideally suited for storage processing applications. The PowerPC 440 superscalar core delivers CPU speeds of up to 667 MHz (1,334 DMIPS), three PCI-X 266 DDR version 2.0 interfaces, to move data between host, disk drives and mirrored disks. Large RAID disk caching of up to 4GBytes is possible with an on-chip high-speed double data rate DDR1/DDR2 SDRAM memory controller. Also integrated in the 440SP are I20 messaging unit, DMA controllers, 256KB L2 cache, and an on-chip 10/100/1000 Mbps Ethernet management port. The 440SP further increases performance in RAID applications by employing a unique two-way cross-bar Processor Local Bus (PLB), providing up to 10 Gigabytes per second of on-chip bandwidth. The 440SP also includes hardware acceleration blocks with XOR functions and DMA controller designed to offload and accelerate the processing of common RAID algorithms.

Built with industry leading reliability, HP's SAS storage enclosures and HP ProLiant industry standard x86 based servers provide improved levels of flexibility, scalability, interoperability and performance in completely integrated solutions. Targeting multi-server deployments in space constrained environments; the HP ProLiant DL series has rack models designed for maximum density and manageability. HP's ProLiant ML series, available in both tower and rack models, provides optimum expansion for internal storage and I/O capabilities in remote and branch offices as well as data centers.

"As demand for high-capacity, high-bandwidth, reliable, always-on storage grows, the need for specialized storage processor solutions increases. We believe that the 440SP and 440SPe storage processors represent state-of-the-art solutions and we are delighted that HP has selected our products for use in their industry leading ProLiant servers," said Sam Fuller, AMCC's vice president of marketing, Embedded Products.

"AMCC's 440SP has been instrumental to HP launching the first complete SAS portfolio in the industry. Customers will benefit from the rich feature set of HP SAS solutions enabled by the leading edge performance of the 440SP," said Javier Izquierdo, director of server storage development, HP. "SAS will enable seamless customer choice between high-performance enterprise drive solutions and low-cost, high-capacity, archival solutions based on SATA."

AMCC's PowerPC processors are supported by AMCC and more than 50 third-party vendors who provide a full range of software, boards and development tools necessary for manufacturers to develop products quickly and efficiently.
