Unity XT 380F/380 Unified Storage

Unity XT 380F/380 Unified Storage Overview

The Unity XT 380F/380 is a unified storage array from the Dell Unity XT family. The pair covers both ends of the flash spectrum: the all-flash 380F model is built for latency-sensitive block and file workloads, while the hybrid 380 model mixes SSDs with 10K and 7.2K NL-SAS drives for workloads that do not need the speed and low latency of an NVMe architecture. Both are built on the same platform: dual-active storage processors with two Intel CPUs (12 cores per array, 1.7 GHz), 128 GB of system memory and cache per array, and a 2U disk processor enclosure holding twenty-five 2.5-inch drives with full 12 Gb SAS back-end connectivity.

Unity XT delivers up to twice the IOPS of the previous Dell Unity models and supports up to 50% more drives, and every array includes a rich set of all-inclusive enterprise software for block, file and VMware vVols. The Unity XT 380F/380 scales to 500 drives and 2.4 PB of raw capacity, and reaches up to 600K IOPS on all-flash configurations. It targets small-scale unified workloads: SMB file serving, virtualisation, databases, and file and print services.

Compute and Memory

• Processors: 2 x Intel CPUs, 12 cores per array, 1.7 GHz
• Memory: 128 GB system memory and cache per array
• Controller design: dual-active storage processors with full 12 Gb SAS back-end connectivity and a multicore architected operating environment

Expansion Capacity

Capacity is added through Disk Array Enclosures (DAEs). All-flash models use 2.5-inch drives in a 2U twenty-five drive tray; hybrid models also support 3.5-inch NL-SAS drives in a 3U fifteen drive tray. All models require four system drives. 107 GB per system drive is consumed by the operating environment software and data structures on the 380F/380 (150 GB per system drive on the 480, 680 and 880 models).
