Abstract
A redundant controller data storage system having a hot insertion system and method is described. In one aspect, the method of hot inserting a controller in a redundant controller system includes configuring a first controller to include a first memory, a task processor and a system operation processor. The first memory includes a first memory image. The redundant controller system is operated via the first controller. The system operation commands are processed via the system operation processor. A second controller including a second memory, is inserted into the redundant controller system. Background tasks are processed during the processing of system operation commands via the first controller using the task processor, including copying the first memory image to the second memory.
