EMC MirrorView for remote mirroringTwo storage processors (SP) manage the EMC Clariion hardware RAID features. All Clariion has two SP.
EMC SnapView for creating snapshots and clones
EMC SAN Copy for copying data between storage systems.
The main hardware difference in base CX700 from CX500/CX300 is that CX700 comes with a Storage Processor Enclosure (SPE) and, in addition, requires at least one 2 Gbit Disk Array Enclosure (DAE2) with 15 Fibre Channel (FC) disks.

The shared (direct or switched) installation require EMC Access Logix software to control LUN access. The clustered-direct installation can use cluster software controlling LUN access.
Switch zoning can prevent communication with an SP but not with specific LUNs attached to an SP. Storage Groups are required for access control with LUNs. Storage Group is a group of LUNs within storage system assigned to specific servers and inaccessible to others. Access Logix enforces the servers permission to a storage group.
Clariion supports five RAID levels (RAID 5, 3, 1, 0, 1/0) and two other disk configurations (individual unit, global "hot" spare). An additional type of redundant disk, remote mirror for any RAID except hot spare.
One RAID 5 (Individual Access Array) group, consists of three to sixteen disks, offers excellent read performance. Up to 128 LUNs can be created with in one RAID 5 group.
