From Wikipedia, the free encyclopedia Dell EMC Unity is one of Dell EMC ’s mid-range storage array product lines. It is marketed as software-defined storage. 2008. Emergency Medical Care, a Canadian ambulance service; Endoplasmic reticulum membrane protein … It can extend existing cache capacities up to 2 terabytes.Subsequent processor and bandwidth upgrades led to a new CX lineup (CX300, CX500, CX700) and a low-end, SATA-based CLARiiON array, the AX100 (now updated to AX150). LenovoEMC (formerly Iomega), sometimes styled Lenovo | EMC², is a producer of external, portable, and networked storage products.Established in the 1980s in Roy, Utah, as Iomega, LenovoEMC has sold more than 410 million digital storage drives and disks.It was formerly a public company. The first CLARiiON was developed in 1992 by Data General Corporation, one of the first minicomputer companies. The operating environment, FLARE (Fibre Logic Array Runtime Environment), resides on the first four disks of the first DAE (bus 0 enclosure 0), which is also supplied by the integrated UPS. EMC Elastic Cloud Storage (ECS), formerly Project Nile, is an object storage software product marketed by EMC Corporation. The Zip drive was Iomega's most notable product. Supported RAID levels are 1/0, 0, 1, 3, 5, and 6; the disks can be configured into groups with different RAID levels.The CLARiiON was a dual controller active/passive array, meaning that it had a mirrored write cache, but only one controller was actively serving requests for any single LUN presented to initiators.This could cause issues with unsuspecting clients, one path would always appear dead.

The CX4-480 and CX-960 support fibre channel solid state flash drives introduced by EMC for the Symmetrix DMX-4 in January 2008. It provides a cluster-based storage array based on industry standard hardware, and is scalable to 50 petabytes in a single filesystem using its FreeBSD -derived OneFS file system. Storage is connected via back-end loops with up to 120 drives per loop, the drives are contained in Disk Array Enclosures (DAEs) of 15 drives each.The CX3 series originally consisted of CX3-20, CX3-40, and CX3-80 models. The CX4 series supports Fibre Channel and iSCSI host connectivity.Crashes were uncommon when the use of FC fabrics become common place, but the general issue of trespassing lived on until a certain firmware (FLARE) level with ALUA support was released, ca.
