'''CN5740-800 SP''' is a {{arch|64}} [[octa-core]] [[MIPS]] storage processor (SP) designed by [[Cavium]] and introduced in [[2007]]. This processor, which incorporates eight {{cavium|cnMIPS|l=arch}} cores, operates at 800 MHz and supports up to DDR2-800 dual channel ECC memory. This MPU includes a number of hardware accelerators specifically for improving the performance of storage and network software such as [[RAID]], networking, TCP & [[QoS]] acceleration.
