Hitachi Universal Volume Manager

What Hitachi Universal Volume Manager is
Hitachi Universal Volume Manager (UVM) connects external block storage to a local storage system and presents mapped volumes to hosts like local volumes. Documented uses include assigning external capacity to hosts, backup, and moving data from older storage. External paths use Fibre Channel; iSCSI is also available for VSP One Block. UVM documents compatible systems from other vendors and provides a generic Fibre Channel profile for systems conforming to part of the standard SCSI Primary Commands. Operations can be managed through REST API, Storage Advisor Embedded, or CCI. Mapped volumes can be used with related products such as Dynamic Provisioning, Global-active device, ShadowImage, TrueCopy, Universal Replicator, 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. Each mapped volume is limited to 256 TB; data beyond that limit cannot be accessed. UVM requires a license on the local storage system, and pricing is on request.
Who it suits
UVM is for teams configuring storage connections and volumes on a local storage system, with hosts accessing external volumes through it. It may suit storage administrators managing supported block systems or planning storage migration.
What it does well

What to know first
- Only block storage can connect as external storage.
- Mapped external volumes are limited to 256 TB each.
- Requires a local storage system license.
- Pricing is available on request.
Limits
UVM requires a license on the local storage system. Each mapped external volume is limited to 256 TB, and data beyond that capacity cannot be accessed.

Getting started
- Visit Hitachi Vantara’s Virtual Storage Platform page.
- Confirm that the local storage system has a Universal Volume Manager license.
- Connect compatible external block storage using Fibre Channel; iSCSI is also available for VSP One Block.
- Configure UVM operations through REST API, Storage Advisor Embedded, or CCI.
- Contact Hitachi customer support for connection type details or installation using the generic UVM profile.
- Request pricing from Hitachi.
Verdict
UVM can bring compatible external block storage under a local system's management and expose its mapped volumes to hosts. Check supported systems, connection types, license requirements, and the per-volume capacity limit.
Questions
What does Universal Volume Manager do?
It virtualizes external storage so different storage system models can be used as one storage system. Hosts can use mapped external volumes like local volumes.
Which storage can it connect?
Only block storage is supported as an external storage system. Connections use Fibre Channel; iSCSI is also available for VSP One Block.
Which storage systems are supported?
The documented platforms include Hitachi VSP systems and systems from HPE, Fujitsu, IBM, Dell EMC, Seagate, Sun, and SGI, among others.
How much does UVM cost?
Pricing is on request. A Universal Volume Manager license is required on the local storage system.
What is the mapped volume capacity limit?
The documented maximum is 256 TB per mapped external volume. Data above that capacity cannot be accessed.
How can UVM be managed?
The documentation identifies REST API, Storage Advisor Embedded, and CCI as interfaces for UVM operations.
