Universal Storage Platform

Universal Storage Platform (USP) was the brand name for an Hitachi Data Systems line of computer data storage disk arrays circa 2004 to 2010.

History
The Hitachi Universal Storage Platform was first introduced in 2004. An entry-level enterprise and high-end midrange model, the Network Storage Controller was introduced in 2005. The Universal Storage Platform was one of the first disk arrays to virtualize other disk arrays in the appliance instead of in the network.

The second generation Universal Storage Platform V replaced the original Universal Storage Platform in 2007 and the Universal Storage Platform VM replacing the original Network Storage Controller also in 2007.

Architecture
At the core of the Universal Storage Platform V and VM is a fully fault tolerant, high performance, non-blocking, silicon based switched architecture designed to provide the bandwidth needed to support infrastructure consolidation of enterprise file and block-based storage services on and behind a single platform.

Notable features include:


 * Supports online local and distance replication and migration of data non disruptively internally and between heterogeneous storage, without interrupting application i/o through use of products such as Tiered Storage Manager, ShadowImage, TrueCopy  and Universal Replicator.
 * Enables virtualization of external SAN storage from Hitachi and other vendors into one pool
 * Storage partitioning provides the ability to host multiple applications on a single storage system without allowing the actions of one set of users to affect the Quality of Service of others.
 * Supports thin provisioning and storage reclamation on internal and external virtualized storage
 * Provides encryption, WORM and data shredding services, data resilience and business continuity services and content management services.

Storage management
The Hitachi Storage Command Suite (formerly the HiCommand Storage Management Suite) provides integrated storage resource management, tiered storage and business continuity software solutions allowing customers to align their storage with application requirements based upon metrics including Quality-of-Service, Service Level Objectives, Recovery Time Objectives and Recovery Point Objectives.

Open Standards management interfaces such as SNMP and SMI-S are also supported.
