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.
