A Method of Dynamic Load Storage with Soft-Hard Coordination

Abstract

The invention discloses a soft and hard synergic dynamic load storage method. The method comprises the steps of adopting a cold and hot tree in a data disk layout for recording disk strips, and dynamically allocating the disk strips. The energy is saved on the condition that the requirement for data transmission bandwidth is met, the xor computing part which is originally conducted through a CPU is achieved through an FPGA hardware algorithm, and the method is very suitable for a large-sized storage system for dynamic load change. According to the method, a novel disk layout mode is adopted and combined with hardware to be in charge of dynamic storage in the software and hardware combination mode, an opened disk is more reasonably utilized, the extra energy consumption brought by conversion of the disk is reduced, the address computing part is achieved through a software algorithm, the xor computing part is achieved through hardware, the disk energy consumption and the CPU resource when the data is stored are reduced, and the performance of an entire RAID storage framework is improved.

Problems solved by technology

However, when the algorithm selects the stripes, it does not take into account the use of the disks that have been turned on as much as possible, and the algorithm all uses the traditional RAID architecture, and the XOR calculation in the traditional RAID architecture will consume a lot of CPU resources.
