Simplify the path to IT transformation and unlock the full potential of your data capital with the new Dell EMC Unity XT storage arrays that feature up to 2X more IOPS, more memory, and up to 50% more drives than previous Dell EMC Unity models. These All-Flash and Hybrid storage systems with dual-active controller architecture and enterprise-class features are designed for performance, optimized for efficiency with up to 5:1 data reduction, and built to simplify your multi-cloud journey.

Architecture

Based on the powerful family of Intel Xeon™ processors, Dell EMC’s Unity XT storage systems implement an integrated architecture for block, file, and VMware VVols with concurrent support for native NAS, iSCSI, and Fibre Channel protocols. Each system leverages dual storage processors, full 12 Gb SAS back end connectivity and Dell EMC’s patented multicore architected operating environment to deliver unparalleled performance & efficiency. Additional storage capacity is added via Disk Array Enclosures (DAEs).

Min/Max Drives 6/500 6/750 6/1000 6/1500
Array Enclosure A 2U Disk Processor Enclosure (DPE) with twenty five 2.5” drives
Drive Enclosure (DAE – Disk Array Enclosure) All-Flash (F) models support 2.5” drives in 2U twenty five drive and 3U eighty drive trays.
Hybrid models support 2.5“ drives in 2U twenty five drive and 3U eighty drive trays; and 3.5” drives in 3U fifteen drive trays.
Standby Power System Dell EMC Unity systems are powered by 2 power supplies (PS) per DPE/DAE. Each power supply can provide power to the entire module if the peer PS has been removed or is faulted. DPE power during a power failure is provided by a Battery Back Up (BBU) module. BBU is located within the SP enclosure and provides power to a single module (power zone)
