™|EMC®CX4-120
Bringing a new level of performance, flexibility, and resource utilisation to
enterprise-class storage
EntErprisE-CLass storagE
Dell/EMC CX series storage arrays have built a reputation for performance, ease of use, scalability,
flexibility, reliability, and investment protection since their initial launch in 2002. Now in their fourth
generation, the new CX4 arrays build on that reputation and are designed to greatly increase
performance and capacity from the previous generation. The CX4 series provides impressive
flexibility and investment protection with the introduction of new UltraFlexTM technology.
CX4-120
The Dell/EMC CX4-120 is the entry point to the CX family arrays and oers enterprise storage
features at an aordable cost. It is an ideal product for customers who require increased capacity
and modularity in a small but scalable footprint with enterprise-level data protection and high
availability.
ULtraFLEX tEChnoLogy
The CX4 series introduces UltraFlex technology that enables the user to customise the network
interconnect and number of ports needed to meet current and future storage requirements
The CX4-120 comes standard with both true end-to-end 4Gbit Fibre Channel and 1Gbit iSCSI
connectivity and can be expanded with additional FC or iSCSI ports, as well as new network
technologies, such as 8Gbit Fibre Channel and 10Gbit iSCSI, as they become available.
MassivE sCaLabiLity anD FLEXibiLity
The CX4-120 supports up to 120 hard drives, connects to as many as 128 highly available hosts
in a SAN, and has six UltraFlex I/O slots (three per controller) for connectivity customisation,
helping to provide investment protection for your enterprise storage needs. The CX4-120 consists
of a 2U storage processing enclosure (SPE), a 1U standby power supply (SPS), and 3U disk array
enclosures (DAEs), which contain up to 15 hard drives.

rEDUCE opErationaL Costs
Virtual provisioning1enables the CX4-120
to allocate space only as it is needed by
hosts instead of setting up a large pool
of storage that goes unused. The result
is that fewer drives are required, helping
to reduce hardware costs, management
time and costs, and power consumption.
EnhanCED Data tiEring
With the addition of energy-ecient
SATA drives, new options for data tiering
are available for the CX4-120 that can
help reduce costs and maximise resource
utilisation. Data can be tiered on 15K RPM
FC, 10K RPM FC, 7.2K RPM SATA, and
5.4K RPM SATA drives within the same
storage array.

CooLing Costs
Low-power SATA drives consume up to
32% less energy than standard 7.2K RPM
SATA drives.* In addition, the array uses
adaptive cooling where fans spin only as
fast as needed to keep it cool.
ManagE yoUr Data
With Dell/EMC storage arrays, you can
easily deploy, expand, and redeploy
storage. You can migrate data
seamlessly between dierent classes
of drives and RAID types to deliver the
optimal combination of performance
and availability. And with Virtual LUN
technology, data migration takes place
dynamically and eortlessly, helping
avoid disruption. Dell/EMC storage arrays
support the EMC data replication and
migration applications, Mirrorview™ and
SAN Copy™. These optional tools let you
remotely mirror data from one array to
another to help meet disaster recovery
goals or to simply move data across
arrays.
soLvE yoUr probLEMs
Dell/EMC storage arrays are integrated
into Dell’s Exchange®, SQL Server®, and
Oracle® solutions, which oer tested
and validated reference architectures to
help solve your messaging and database
challenges.
* Based on drive specifications. Actual power consumption will vary based on configuration, usage,
and manufacturing variability.
1Virtual Provisioning/ 450GB 15k FC drive are expected to be available in Oct/Nov 2008. Date is
an estimate only and subject to delays.
2For hard drives, one TB = one trillion bytes; one GB means 1 billion bytes. Actual capacity varies
with preloaded material and operating environment and will be less.
