Dell EMC Unity XT – Product Analysis

Last updated April 30th, 2019 for new models. 28-page deep dive into the EMC Unity Product. Includes highlights, functionality, architecture and more.

Dell EMC announced the midrange unified storage system called Unity XT in May of 2016. The Dell EMC Unity XT system is derived from the Dell EMC VNX/VNXe series of storage systems with a new operating environment and new hardware configuration. Unity XT systems have both all flash and hybrid models and are scale-up systems with dual active controllers. The unified systems support block and file with the file software originally released in the VNXe3200.

There are 8 models, 380/380F, 480/480F, 680/680F, 880/880F.

Many of the software functions of the Dell EMC Unity XT systems were extracted from VNX software. The Unity XT systems use a SuSE Linux kernel and support Docker containers. The filesystem software supports multiple NAS Servers, which were previously called virtual data movers. Unisphere is the element manager as a web GUI, implemented with HTLM5.

The dual controllers are packaged in a 2U enclosure along with either 25 2.5” devices or 12 3.5” devices that are SAS attached. Additional devices can be added with Device Array Enclosures of either 15 3.5” devices in a 3U enclosure or 80 2.5” devices in a 3U enclosure. Software features are included in the base price and include snapshots, synchronous and asynchronous remote replication, VVOLs and VASA support. Telemetry data is collected and analyzed with a SaaS product called CloudIQ. Health checks are done and proactive maintenance is scheduled based on the analytics.

The SSDs in the Dell EMC Unity XT have a lifetime warranty as long as a maintenance contract is in place. In addition, the maintenance price is guaranteed not to be increased from the initial purchase.

The Unity XT systems provide a wide set of connectivity options for block access and for file access as a NAS system.
