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

Currently,{{When|date=February 2011}} two models are available the AX4 and the AX150.
The AX150 supports up to 12 [[Serial ATA]] disks with either 250, 500 or 750 [[Gigabyte|GB]] (1 GB = 10<sup>9</sup> [[byte|B]]) at a throughput of 150 (250&nbsp;GB disks) or 300&nbsp;MB/s (500, 750&nbsp;GB disks) and, optionally, [[Native Command Queuing|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&nbsp;Gbit/s (with both [[Arbitrated loop|AL]] and [[Switched fabric|SW]] configurations), iSCSI is physically limited to max. 1&nbsp;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&nbsp;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&nbsp;Gbit/s) and iSCSI (max. 1&nbsp;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|date=February 2011}} 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 Channel 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 fibre channel solid state flash drives introduced by EMC for the Symmetrix DMX-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 8&nbsp;GBit Fibre Channel and 10&nbsp;GBit Ethernet/iSCSI.
