High availability features
Two interconnected controllers ensure that the failure of a controller c omponent does not disable the
system. A sing le controller can fully support an entire system until the defective controller, or controller
component, is repaired. For EVA5000 config urations, the complete data redundancy configuration
includes two Loop A and two Loop B data paths. For EVA3000 configurations, data redundancy is
accomplished with t wo Loop A data paths.
Each controller has two lead-acid cache batteries that provide power to the cache memory. W hen the
batteries a re fully charged, they can provide power to the cache for up to 96 hours.
Operator control panel
The operator control panel (OCP) provides a direct interface to e ach controller. From the OCP you
can display storage system status and configuration information, shut down the storage system, a nd
manage
the password.
The OCP
includes a 40-character LCD alphanumeric display, four push buttons, and four status indicators
See Figure 23.
HP Command View EVA is the tool you will typically use to display storage system status and confi guration
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.
