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.

Two types of DAE2s are available:
a standard DAE2 version with high-performance Fibre Channel
disks
a DAE2-ATA version with economical ATA (Advanced
Technology Attachment) disks.
Figure 1-1 shows a typical CX700 storage system.
