The AX series is considered the entry-level disk array.

Currently two models AX4 and the AX150 are available. The AX150 supports up to 12 Serial

ATA disks with either 250, 500 or 750 GB (1 GB = 109 B) at a throughput of 150 (250 GB

disks) or 300 MB/s (500, 750 GB disks) and, optionally, NCQ. Supported RAID levels are RAID

5 (with min. 3 disks) and RAID 1/0 (min. 4 disks). The Fibre Channel connection supports

transfer speeds of up to 2 Gbit/s (with both AL and SW configurations),iSCSI is physically

limited to max. 1 Gbit/s. The AX150 is available in four configurations which differ in

connection and number of controllers.

The AX4 is the successor of the AX150 and can support up to 60 Serial ATA or Serial Attached

SCSI disks (with "Expansion Pack"). The base version has only place for 12 disks. Similar to the

AX150 it is available in iSCSI or Fibre Channel configurations. Opposed to the AX150 the AX4

supports Fibre Channel transfer speeds of up to 4 Gbit/s.

CX series

The CX series supports both SATA and Fibre Channel disks. Supported RAID levels are 1/0, 0,

1, 3, 5, and 6; the disks can be configured into groups with different RAID levels.

Models of the CX series come in two configurations: Fibre Channel (transfer speeds max. 2

Gbit/s) and iSCSI (max. 1 Gbit/s). The exception is the CX700, which is FC only. The names of

the iSCSI models end with an i, e.g.CX500i.

CX3 series

The CX3 series originally consisted of CX3-20, CX3-40, and CX3-80 models. Later the series

was refreshed to include the CX3-10 and the 'i' and 'f' identifiers.

CX4 UltraFlex series

The CX4 UltraFlex series contains multiple models which differ in the maximum number of

disks (SATA or Fibre Channel) and the number of iSCSI and FC connections. The PCI Express

connection between the FC interface and the storage processor allows transfer speeds of up to 4

Gbit/s, while iSCSI supports speeds of max. 1 Gbit/s. All current[when?] models support RAID 0,

1, 1/0, 3, 5, and 6; as with the CX series, groups with differing RAID levels can be created.

Each CX4 array consists of dual redundant hot-swappable components including storage

processors, mirrored cache and battery backup, as well as redundant power supplies. The CX4

series supports Fibre Chanel and iSCSI host connectivity.

Major New Features in the CX4 UltraFlex Series include support for solid state flash drives, 64-

bit FLARE Operating Environment and PCI-Express based SLIC I/O cards. The CX4-480 and

CX-960 support fibrechanel solid state flash drives introduced by EMC for the SymmetrixDMX-4 in January 2008. Solid State Flash drives offer a significant performance advantage over

mechanical drives and provide a new storage tier which EMC calls Tier-0. The new version of

the FLARE operating environment that ships with the CX4 series includes support for the 64-bit

Intel Xeon CPUs in the Storage Processors. The CX4 Series is also the first product to use the

new PCI Express based SLIC I/O cards. The product-agnostic SLIC I/O cards provide more

flexibility for future upgrades as new technologies become available, such as 8GBit Fibre Chanel

and 10GBit Ethernet/iSCSI.
