Components
The MSA1000 Controller is a drive array controller specifically designed for
installation in the MSA1000. The MSA1000 comes equipped with one MSA1000
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. See the “Recovery ROM” and
“ROM Cloning” sections for more information.
