High availability features
Two i nterconnected controllers ensure that the failure of a c ontroller component does n ot disable the
system. A single controller can fully suppor t an entire system until the d efective controller, or controller
component, is repaired. For EVA8000 configurations with more than four disk drive enclosures, the
complete data redundancy configuration includes two Loop A and two Loop B data paths. For EVA4000
and EVA6000 configurations, data redundancy is accomplished with two Loop A data paths.
Each HSV210 controller has two lead-acid cache batteries that provide power to the cache memor y.
Each HSV200 controller has one battery. 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 (OCP ) provides a direct interface to each controll
er. From the OCP you
can display storage system status and configuration information, shut down the storage system, and
manage the password.
The OCP includes a 40-character LCD alphanumeric display, six pushbuttons, and five status indicators
