High availability features
Two interconnected controllers ensure that the failure of a controller component does not disable the
system. A single controller can fully support an entire system until the defective controller, or controller
component, is repaired. For EVA5000 congurations, the complete d a ta redundancy conguration
includes two Loop A and two Loop B data paths. For EVA3000 congurations, data redundancy is
accomplished with two Loop A data paths.
Each controller has t wo lea d-acid cache batteries that provide power to the cache memor y. When the
batteries are fully charged, they can provide power to the cache for up to 96 hours.
Operator control panel
The operator control panel (O CP) provides a direct interface to each controller. From the OCP you
can display storage system status and conguration information, shut down the storage system, and
manage
the password.
The OCP
includes a 40-character LCD alphanumeric display, four push buttons, and four status indicators
See Figure 23.
HP Command V i ew EVA is the tool you w ill typically use to display storage system status and conguration
information or perform the tasks available from the OCP. However, if HP Command View EVA is not
available, the OCP can be used to perform these tasks.
