Sunnyvale, Calif.Applied Micro Circuits Corp. (AMCC) is getting ready to sample the latest 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 a rich feature set and high performance, the PowerPC 460SX is designed to meet the demanding requirements of server direct-attached and external storage applications. The combination of high-performance IO and memory subsystems also make the PowerPC 460SX ideal for high-bandwidth protocol bridging applications.
The PowerPC 460SX, with clock frequencies ranging from 833MHz to 1.4GHz, provides multiple PCI Express 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
1500MB/s RAID 5 and 1400MB/s RAID 6 full stripe write performance. It also includes XTS-AES 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. With these features, the PowerPC 460SX can improve both system performance and data security, by performing RAID 5 and RAID 6 parity calculations while at the same time encrypting and decrypting data in transit and data at rest.
To support the high bandwidth transactions, the PowerPC 460SX features two internal buses that support simultaneous read/write operations for a combined total of 19.2 GBytes/s of peak bandwidth. This bus topology enables concurrent transactions for write data to memory, read data from memory, encrypt/decrypt data, and computation of RAID parities.
Pricing: Recommended distribution resale price of $100-$150 in 10,000-piece quantities; the range is for processor speed and 460SX features.
Availability: Samples will be available in the third quarter of 2008.
