Convention for Storage Capacity Values
Physical storage capacity values (e.g., data drive capacity) are calculated
based on the following values:
1 KB = 1,000 bytes
1 MB = 1,0002bytes
1 GB = 1,0003bytes
1 TB = 1,0004bytes
1 PB = 1,0005bytes
Logical storage capacity values (e.g., logical device capacity) are calculated
based on the following values:
1 KB = 1,024 (210) bytes
1 MB = 1,024 KB or 1,0242bytes
1 GB = 1,024 MB or 1,0243bytes
1 TB = 1,024 GB or 1,0244bytes
1 PB = 1,024 TB or 1,0245bytes
1 block = 512 bytes

Universal Storage Platform V Family
The Hitachi Universal Storage Platform™ V family, the industry’s highest
performing and most scalable storage solution, represents the first
implementation of a large-scale, enterprise-class virtualization layer combined
with thin provisioning software, delivering virtualization of internal and
external storage into one pool. Users realize the consolidation benefits of
external storage virtualization with the efficiencies, power, and cooling
advantages of thin provisioning in one integrated solution.
The Universal Storage Platform V family, which includes the USP V floor
models and the rack-mounted USP VM, offer a wide range of storage and data
services, including thin provisioning with Hitachi Dynamic Provisioning™
software, application-centric storage management and logical partitioning, and
simplified and unified data replication across heterogeneous storage systems.
The Universal Storage Platform V family enables users to deploy applications
within a new framework, leverage and add value to current investments, and
more closely align IT with business objectives.
The Universal Storage Platform V family is an integral part of the Services
Oriented Storage Solutions architecture from Hitachi Data Systems. These
storage systems provide the foundation for matching application requirements
to different classes of storage and deliver critical services such as:
•Business continuity services
•Content management services (search, indexing)
•Non-disruptive data migration
•Volume management across heterogeneous storage arrays
•Thin provisioning
•Security services (immutability, logging, auditing, data shredding)
•Data de-duplication
•I/O load balancing
•Data classification
•File management services
For further information on storage solutions and the Universal Storage
Platform V and VM storage systems, please contact your Hitachi Data Systems
account team.

Hitachi Universal Storage Platform V/VM User and Reference Guide
New and Improved Capabilities
The Hitachi Universal Storage Platform V and VM storage systems offer the
following new and improved capabilities as compared with the TagmaStore
Universal Storage Platform and Network Storage Controller:
•NEW! Hitachi Data-At-Rest Encryption
The new Hitachi data-at-rest encryption feature provides hardware-based
strong encryption (AES-256) that is compatible with both open and
mainframe systems. Encryption can be applied to some or all of the
internal drives with no throughput or latency impacts for data I/O and little
or no disruption to existing applications and infrastructure. Hitachi data-at-
rest encryption includes integrated key management functionality that is
both simple and safe to use.
The Hitachi data-at-rest encryption feature has the added benefit of being
data-center friendly: it uses very little additional power (equivalent of a 25-
watt light bulb), produces negligible amounts of additional heat, and
requires no additional rack space. For further information on data-at-rest
encryption, please contact your Hitachi Data Systems account team.
•NEW! Hitachi Dynamic Provisioning™
Hitachi Dynamic Provisioning is a new and advanced thin-provisioning
software product that provides “virtual storage capacity” to simplify
administration and addition of storage, eliminate application service
interruptions, and reduce costs.
