•  Reduced Total Cost of Ownership (TCO) with improved data 
availability. A new thin provisioning software feature improves data 
availability while reducing storage TCO by allowing customers to allocate 
“virtual” disk storage based on their anticipated future needs, with less 
physical disk than initially required. Additional physical disks can be 
purchased later and installed transparently without interrupting application 
services. 
•  Increased Return on Investment (ROI). The USP V increases ROI by 
providing investment protection and longer life for legacy storage, superior 
storage and server utilization, improved application quality of service, 
lower software licenses/costs, and simplified and centralized storage 
management.  
•  Reduced mainframe storage costs. The USP V lets mainframe 
customers exploit SATA storage either internal to the USP V or externally 
attached to improve data protection, cost-effectively store larger amounts 
DFSMS Migration Level 1 data and offload costly DFSMS mainframe 
processing cycles, or deploy a long-term and secure data archive solution 
for regulatory compliance. The USP V’s virtual private storage machines are 
the ideal compliment to mainframe LPARs for providing workload isolation 
and optimum quality of service. 
•  Application data mobility solutions. The USP V is complemented by a 
rich suite of software solutions for managing storage across an entire 
heterogeneous storage pool: 
–  HiCommand Tiered Storage Manager - lets customers continually adjust 
their storage infrastructure to meet their changing business needs.  
–  HiCommand Tuning Manager and HiCommand Device Manager – let 
customers continually monitor and forecast their storage infrastructure 
needs.  
–  Hitachi ShadowImage In-System Replication and Hitachi Universal 
Replication - deliver proven scalable data-protection for meeting the 
most stringent business continuance and compliance requirements of 
the world’s largest financial institutions. 
–  Hitachi Universal Replication and Hitachi ShadowImage now support 
more volumes and replication pairs than before. Performance has also 
been improved, with support added for more consistency groups spread 
across four USP V systems located at each site within a 2- or 3-
datacenter configuration. 
   
 
Note: The availability of the Hitachi USP V features and functions depends on 
the level of microcode installed.
