Enabling the URz Option(s)
To operate the URz software, PC for the USP V Storage Navigator is required.
For further information on USP V Storage Navigator operations, please refer to
the Storage Navigator User's Guide, or contact your Hitachi Data Systems
account team.
Using Multiple Primary and Secondary Storage Systems
System configuration of up to four primary storage systems and up to four
secondary storage systems is allowed for URz operations. URz can copy data
from more than one primary storage system to more than one secondary
storage system, while maintaining consistency in data update sequence. Even
when a failure occurs in a large computer system consisting of more than one
storage system, you can continue your business tasks by using data in
secondary storage systems.
The following figure illustrates an example of using URz in a system
configuration of three primary storage systems and three secondary storage
systems.
