技术领域technical field
本发明涉及存储技术领域，特别涉及一种多物理层分区计算机体系结构的存储共享系统。The invention relates to the technical field of storage, in particular to a storage sharing system with multi-physical layer partition computer architecture.
背景技术Background technique
现有基于NUMA(NUMA，即Non Uniform Memory Access Architecture，非统一内存访问架构)的多物理层分区计算体系结构中，通过对多处理器计算机系统中的多个CPU和IO资源进行物理层上的划分，可以实现将一个多处理器计算机系统划分成多个独立的分区，每个分区上均包括各自独立的CPU和IO资源。In the existing multi-physical layer partition computing architecture based on NUMA (NUMA, namely Non Uniform Memory Access Architecture, non-uniform memory access architecture), multiple CPUs and IO resources in a multi-processor computer system are allocated on the physical layer. Partitioning can divide a multi-processor computer system into multiple independent partitions, and each partition includes independent CPU and IO resources.
当现有的多物理层分区计算系统工作在多分区模式时，系统中的SAS磁盘阵列会被相应地分成多个独立的小磁盘阵列，不同的小磁盘阵列供不同的分区单独使用，并且每个分区上都需要使用至少一张RAID卡(RAID，即Redundant Arrays of IndependentDisks)，每个分区通过自身对应的RAID卡与相应的小磁盘阵列进行连接，其中，RAID卡的作用是为了在相应的小磁盘阵列上实现RAID功能。图1中示出了传统4分区计算机系统的存储结构示意图。可见，现有技术中，要想在多处理器计算机系统中实现多分区模式，需要为每个分区分配至少一个RAID卡，分区越多，所需的RAID卡的数量也越多，这样会增加系统的硬件成本；另外，由于不同分区对应的小磁盘阵列之间是相互独立的，这样使得不同分区之间无法实现存储数据的共享。When the existing computing system with multiple physical layer partitions works in the multi-partition mode, the SAS disk array in the system will be divided into multiple independent small disk arrays accordingly. Different small disk arrays are used independently by different partitions, and each Each partition needs to use at least one RAID card (RAID, that is, Redundant Arrays of Independent Disks), and each partition is connected to the corresponding small disk array through its own corresponding RAID card. Realize the RAID function on the small disk array. FIG. 1 shows a schematic diagram of a storage structure of a traditional 4-partition computer system. It can be seen that in the prior art, in order to realize the multi-partition mode in a multiprocessor computer system, at least one RAID card needs to be allocated to each partition, and the more partitions, the more the number of required RAID cards, which will increase The hardware cost of the system; in addition, because the small disk arrays corresponding to different partitions are independent of each other, it is impossible to share the stored data between different partitions.
综上所述可以看出，如何实现多分区之间的数据共享并进一步降低系统的硬件成本是目前有待解决的问题。From the above, it can be seen that how to realize data sharing between multiple partitions and further reduce the hardware cost of the system is a problem to be solved at present.
