Clariion - Product Lineup - CX4 UltraFlex Series

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 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 8GBit Fibre Channel and 10GBit Ethernet/iSCSI.

Famous quotes containing the word series:

    There is in every either-or a certain naivete which may well befit the evaluator, but ill- becomes the thinker, for whom opposites dissolve in series of transitions.
    Robert Musil (1880–1942)
