Intel® IOP 341 and Intel IOP 342 With Intel XScale® microarchitecture

The next-generation Intel® I/O processor (Intel® IOP) 341 and Intel® I/O processor (Intel® IOP) 342 deliver full-function IOP-based RAID in a flexible, open architecture.

The Intel® IOP 342 is a high-performance I/O device incorporating two integrated, power-efficient Intel XScale® processors. The Intel IOP 342 divides the load between the two processors, ideal for situations that require a dedicated processor for separate applications or split functionality. This ability enables users to optimize and tailor different types of solutions for maximum performance. For example, RAID calculations or near real-time functionality can be dedicated to one processor, leaving the second processor to handle computing functions that have different performance requirements such as a user interface. Distributed processing of independent tasks greatly reduces the time and power required of each processor and customizes solutions for maximum processor utilization.
