GPU RAID A Hierarchical RAID's Parity Generation System using Pass-through GPU in Multi Virtual-Machine Environment

摘要

The present invention relates to a hierarchical RAID parity generation system using pass-through GPUs in a multi-virtual machine environment, in which parity of data requested to be written is stored and parity is stored together with requested data. Pass-through GPU; A plurality of data nodes constituted of a plurality of storage media, in which requested data and parity are stored; The method of claim 1, further comprising: chunking the requested data with a plurality of data chunks, chunking the requested data to be grouped into N (N is a natural number) division, and generating and storing parity (hereinafter referred to as outer parity) Master virtual machine; And a slave virtual machine for generating parity (hereinafter referred to as internal parity) of data chunks belonging to one group and storing data chunks and internal parities of the group in one data node. With such a system, it is possible to reduce data copy overhead and perform high performance encoding by using multiple virtual machines.
