1. A system, comprising:
a first non-volatile storage device supporting a cache coherent interconnect protocol, the cache coherent interconnect protocol including a block level protocol and a byte level protocol;
a second non-volatile storage device supporting the cache coherent interconnect protocol; and
a redundant array of independent disks (RAID) circuit communicating with the first non-volatile storage device and the second non-volatile storage device, the RAID circuit applying a RAID level to stripe a first data across the first non-volatile storage device and the second non-volatile storage device, the RAID circuit configured to receive a request using the byte level protocol and to access a second data on the first non-volatile storage device.
