MSA1000 Hardware Components

MSA1000 Controller

The MSA1000 Controller is a drive array controller specifically designed for
installation in the MSA1000. The MSA1000 comes equipped with one Controller
installed. An additional controller for redundancy can be purchased separately.
To ensure uninterrupted service, two copies of the controller firmware are stored
in Read Only Memory (ROM) on the controller.

MSA1000 Controller Display

Each array controller in an MSA1000 contains an integrated Liquid Crystal
Display (LCD). This module is used for displaying informational and error
messages, showing the status of the module, and for providing user input when
required. Traditional Power-On Self-Test (POST) messages issued by PCI-based
array controllers have been combined with runtime event notification messages to
create a new set of controller display messages.
The following figure and supporting table illustrate and define the features of the
MSA1000 controller display panel.
