Applied Micro Circuits Corp. (AMCC) introduces the newest member of its storage processor family, the PowerPC 460SX. Based on the Power Architecture standard, the PowerPC 460SX storage processor integrates a PowerPC core and specialized functions for high-performance storage and storage networking applications.

With clock frequencies ranging from 833MHz to 1.4GHz, the PowerPC 460SX provides multiple PCIe Gen 2 interfaces for high bandwidth peripheral connectivity and efficient PCIe to PCIe bridging. For storage applications, the PowerPC 460SX provides high throughput RAID 5 and RAID 6 hardware-acceleration support capable of achieving 1500Mbps RAID 5 and 1400Mbps RAID 6 full stripe write performance. It also includes XTSAES and GCM-AES encryption acceleration that is compliant with the IEEE 1619 and 1619.1 standards. For network attachment, the PowerPC 460SX includes four GbE Ethernet MACs, TCI/IP assist, QoS and a crypto engine for IPSec and SSL.

To support the high bandwidth transactions, the PowerPC 460SX features two internal buses that support simultaneous read/write operations for a combined total of 19.2Gbps of peak bandwidth. This bus topology says AMCC, enables concurrent transactions for write data to memory, read data from memory, encrypt/decrypt data, and computation of RAID parities.

"Customers are demanding high-performance, feature-rich storage solutions which increase throughput while lowering power consumption," said Sam Fuller, vice president of marketing for AMCC. "Our new storage processor enables new storage systems to take full advantage of the new 6G SAS and 8G Fibre Channel technologies and maintains AMCC's performance and feature leadership in storage processing."

Samples of the PowerPC 460SX will be available in Q3.
