AMCC Unveils Advanced PowerPC 460SX Storage Processor for High Throughput RAID Acceleration
- click image to enlarge
AMCC announces the newest member of its storage processor family, the PowerPC(R) 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 unique combination of high-performance IO and memory subsystems also make the PowerPC 460SX ideal for high-bandwidth protocol bridging applications.
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.
Samples of the PowerPC 460SX will be available in 3Q08.
