4.12. CX600 Dual SP
4.12.1. Highlights
The CX600 is the sixth generation of the DAS line (called NDAS). CX600 provides a powerful
storage foundation that offers an end to end 2 Gb fibre channel technology and a raw capacity up to
17.5 TB. With a fully redundant and highly available architecture with no single points of failure, the
CX600 retains all of the same data integrity and high availability features of the DAS offer. This
includes global hot spares, redundant power and cooling, on-line RAID group expansion and data path
parity checking throughout the array.
