EMC CLARiiON CX4 Series Ordering
Information and Con%guration Guidelines
This document outlines CLARiiON CX4 series con%guration rules and ordering
guidelines. The latest pricing will be published in the December 2009 release of
Direct Express and Channel Express.
CLARiiON CX4 Con gurations
CLARiiON CX4 storage arrays include four models—CLARiiON CX4-120, CX4-240,
CX4-480, and CX4-960. These models are available as base models that contain
both Fibre Channel and iSCSI connectivity ports, plus the ability to add additional
optional host connectivity ports through UltraFlex I/O modules. The “C” designated
for ordering model numbers denotes the current I/O con%guration with 4 Gb/s Fibre
Channel and 1 Gb/s iSCSI ports. The “C8” designated for ordering model numbers
denotes the current I/O con%guration with 8 Gb/s Fibre Channel and 1 Gb/s iSCSI
ports. The “C8x” designated for ordering model numbers denotes the current I/O
con%guration with 8 Gb/s Fibre Channel and 10 Gb/s iSCSI ports. See Ordering
Information table below for more details.

All models in the CLARiiON systems (CX4 -120, CX4-240, CX4-480, and CX4-960) have two Storage
Processors in each chassis.

Not all I/O slots are open; systems are factory precon%gured with iSCSI and Fibre Channel ports.
Included Building Blocks
The CLARiiON CX4 series storage platform consists of these modular assemblies:
SPE (storage processor enclosure) and SPS (standby power supply):
SPEs include two storage processors for redundancy. Each SPE is shipped
with the two SPS, except the CLARiiON CX4-120, which has one SPS and can
be ordered with a second. A second SPS can be ordered using model CX4-
SPS.
UltraFlex I/O Modules: Depending on the system, a certain number of pre-
con%gured connectivity modules with iSCSI and Fibre Channel are included in
each initial starting system, more can be added at later time.
UltraPoint DAE: Holds up to 15 drives. Connects to array through Fibre
Channel at 4 Gb/s; additional DAEs will expand system capacity.
Vault Pack: The initial %ve drives in the %rst DAE are used for FLARE
operating system and vault drives.
