Method for hot swapping a programmable storage adapter using a programmable processor for selectively enabling or disabling power to adapter slot in response to respective request signals

摘要

A software architecture for the hot add and swap of adapters. The software architecture allows users to replace failed components, upgrade outdated components, and add new functionality, such as new network interfaces, disk interface adapters and storage, without impacting existing users. The software architecture supports the hot add and swap of off-the-shelf adapters, including those adapters that are programmable.
