Introducing CX300, CX500, CX500i, and CX700 Storage Systems
EMC CLARiiON CX300, CX500, CX500i, and CX700 disk-array
storage systems provide terabytes of disk storage capacity, high
transfer rates, flexible configurations, and highly available data at
low cost. Their hardware RAID features are provided by two storage
processors (SPs).
Table 1-1 outlines each storage system enclosure and disk capacities.
