The CX4-240 is a Dell EMC CLARiiON storage array from the fourth generation of the CX series. The Dell EMC CX4-240 connects to 240 hard drives and to as many as 512 highly available hosts in a SAN, offers 8 UltraFlex I/O slots for connectivity customization, and supports enterprise flash drives. All CX4 arrays offer data in-place upgrades within the CX4 family and from previous generations.
UltraFlex technology lets the CX4-240 be customized for the network interconnect and the number of ports. The three base models are four 4Gbit Fibre Channel with four 1Gbit iSCSI, four 8Gbit Fibre Channel with four 1Gbit iSCSI, and four 8Gbit Fibre Channel with four 10Gbit iSCSI. Optional UltraFlex I/O modules add 4Gbit or 8Gbit Fibre Channel and 1Gbit or 10Gbit iSCSI.
Two storage processors share 8GB of system cache as standard, and the cache reaches up to 100GB with the optional FAST Cache. Raw capacity reaches 144TB with Fibre Channel drives and 459TB with high-capacity SATA drives. Available drives are enterprise flash, 15k and 10k rpm Fibre Channel, 7.2k rpm SATA II and 5.4k rpm low-power SATA II, and fully automated storage tiering moves 1GB chunks of data between these tiers. RAID levels are 0, 1, 1/0, 3, 5 and 6.
Unisphere is the management interface for the array and controls current and legacy CX environments. Available software includes SnapView, MirrorView, PowerPath, SAN Copy, Thin Provisioning and LUN Compression. Operating system support covers Windows 2000 Server, Windows Server 2003 and 2008, Linux, Solaris, VMware, AIX and HP-UX, and the supported servers are all dual- and quad-socket Dell PowerEdge servers plus a variety of Compaq, HP, IBM and Sun servers validated by EMC.
The storage processing enclosure with standby power supplies is 3 EIA units, 5.25 in. (13.33 cm) high, 17.5 in. (44.45 cm) wide and 24.25 in. (61.6 cm) deep, and weighs up to 99.5 lb (45.4 kg). The 4Gbit Fibre Channel point-to-point disk array expansion enclosure is also 3 EIA units high and weighs up to 68 lb (30.9 kg) in its maximum configuration.
