See Figure 49. Each Enterprise Storage System includes a pair of HSV100
controllers.

High Availability Features
Two interconnected HSV100 controllers ensure that the failure of a controller
element (such as transceiver, cable, Fibre Channel port, and so forth) does not
disable the system. The complete data redundancy includes two Loop A data
paths.
A single controller can fully support an entire system until the defective controller,
or controller element, is repaired.
If a blower or power supply fails, it can be replaced without shutting down the
system.
Each controller has two lead-acid cache battery assemblies that provide power to
the cache memory dual in-line memory modules (DIMMs). Each battery
assembly has three lead-acid, nonspillable cells. When both battery assemblies are
fully charged, they can provide power to the DIMMs for up to 96 hours.
