Abstract

The invention provides a storage control redundancy method based on multiple NUMA physical layer partitions. The method relates to a plurality of SAS disk arrays arranged in a server system, and each SAS disk array comprises a master port and a slave port. The method is specifically achieved through the steps that single-partition or multi-partition selection is conducted on a logic controller through a main board jumper or single-partition or multi-partition selection is conducted on the logic controller in a management and monitoring service interface, and the logic controller is detected; according to different detection results, different storage control allocation methods are adopted. Compared with the prior art, the storage control redundancy method based on the multiple NUMA physical layer partitions is characterized in that physical-layer partition can be conducted on a plurality of processors and IO resources of a computer system, and therefore the computer system with multiple processors is partitioned into a plurality of independent multi-processor systems, and a complete computer system can be formed by coupling the partitioned computer systems. The storage control redundancy method based on the multiple NUMA physical layer partitions is strong in practicability and easy to popularize.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a storage control redundancy method based on NUMA multi-physical layer partitions. Background technique [0002] Ordinary NUMA processor architecture or single processor architecture usually has only one storage control device. Although data is placed on multiple hard drives using RAID technology, I / O operations can overlap in a balanced manner, improving performance. Storing redundant data also increases fault tolerance because multiple hard drives increase the mean time between failures (MTBF). However, it is far from enough to rely solely on the fault tolerance between hard disks in server systems that require high reliability. Once the RAID device fails, the entire system disk storage array will collapse. Greatly affects the reliability of the entire system. Therefore, realizing the storage control redundancy design of the server system will be the future development tr...
