Device Overview

Summary

The  SRCv 12G 8-port RAID-on-Chip (ROC) Controller offers performance improvements with an extremely efficient and scalable architecture, eliminating system performance limitations of traditional ROC devices. In addition to its highly optimized architecture, the SRCv 12G, provides an easy-to-port application programming environment for rapid time-to-market.

The SRCv 12 Gbps architecture is featured on Adaptec® Series 8 RAID Adapters.
