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.

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.
