Summary

Hitachi Universal Volume Manager (UVM) lets a local storage system connect external block storage and present mapped volumes to hosts as though they were local. Documented uses include assigning external volumes to hosts, backup and migration from an older storage system. Connections use Fibre Channel, with iSCSI also available for VSP One Block. UVM documents supported external systems from other vendors and a generic Fibre Channel profile for systems that conform to part of the standard SCSI Primary Commands set. Operations are available through REST API, Storage Advisor Embedded and CCI. Mapped volumes can also be used with products such as Dynamic Provisioning, TrueCopy, ShadowImage, Universal Replicator, Global-active device and Volume Migration. On VSP One Block, up to 4,096 external storage systems can be connected, with up to eight mapping paths per external volume. The documented maximum mapped volume capacity is 256 TB; data beyond that limit cannot be accessed. A license on the local storage system is required, and pricing is on request.

Who it is for

UVM is for teams configuring and managing storage connections and volumes on a local storage system, with hosts accessing external volumes through it. It supports block-storage workloads and migration, backup and provisioning uses.

What is good

Hosts can use mapped external volumes like local volumes
Supports backup and migration use cases
Provides REST API, Storage Advisor Embedded and CCI interfaces
Documents supported third-party storage systems

What to know first

Only block storage can connect as external storage
Mapped volumes are limited to 256 TB
A local storage system license is required

Verdict

UVM presents external block storage through a local storage system and supports several storage-management workflows. Check storage compatibility and the 256 TB per-volume limit before planning a connection.
