Abstract
If a hardware-based RAID (redundant array of independent disks) engine fails, the system can use a driver-based RAID engine in place of the hardware-based RAID engine. Using the driver-based RAID engine may reduce system downtime, and provide redundancy for the RAID system without requiring extra hardware.
Claims20
A method comprising:
- receiving, at a device driver associated with a storage adapter implementing a hardware-based redundant array of independent disks (RAID) engine, an indication of a malfunction preventing the storage adapter from implementing the hardware-based RAID engine;
- and
- implementing a driver-based RAID engine in response to receiving the indication of the malfunction.
An information handling system comprising:
- a processor;
- memory operably coupled to said processor;
- an operating system (OS) to be stored in said memory and executed by said processor;
- a storage adapter operably coupled to implement a hardware-based RAID engine;
- and
- a device driver associated with said storage adapter, said software driver comprising a program of executable instructions to be stored in said memory and executed by said processor, said program of instructions comprising:
- at least one instruction executable to interface between said OS and said storage adapter;
- and
- at least one instruction executable to implement a driver-based RAID engine
6 more elements
A computer readable medium tangibly embodying a program of executable instructions, said program of instructions comprising:
- at least one instruction executable to receive an indication of a malfunction preventing the storage adapter from implementing the hardware-based RAID (redundant array of independent disks) engine;
- and
- at least one instruction executable to implement a driver-based RAID engine in response to receiving the indication of the malfunction.
