Abstract
A redundant array of independent drives controller and board controlled cache off-loading during a power failure is described. Methods associated with the use of the redundant array of independent drives controller and board for controlled cache off-loading during a power failure are also described.
Claims15
A method for controlling cache offload during a power failure comprising:
- monitoring a power supply from a host peripheral component interconnect express connector unit to a redundant array of independent drives controller;
- identifying when a power failure from said power supply to said redundant array of independent drives controller has taken place;
- identifying whether a cache offload is required from said redundant array of independent drives controller cache to a non-volatile storage device at the time of power loss;
- preparing said redundant array of independent drives controller for a cache off-load during said power failure;
- off-loading said cache from said redundant array of independent drives controller during said power failure;
- and
- proceeding to boot or power down said redundant array of independent drives controller after said cache offload from said redundant array of independent drives controller has been completed.
