Paging device management method for shared memory pool, electronic device and storage medium

Abstract

The invention discloses a paging equipment management method of a memory-sharing pool. The method comprises the following steps: searching idle paging equipment according to the memory size of a memory-sharing partition; if the paging equipment for starting the memory-sharing partition is unsearched, firstly calling a sharing storage manager to create disk paging equipment for starting the memory-sharing partition, and then normally starting the memory-sharing partition after recording the paging equipment state and the relation between the paging equipment and the memory-sharing partition. The invention further discloses electronic equipment in which the management method is stored. The invention further discloses a computer readable storage medium for executing the management method. Through the paging matching algorithm disclosed by the invention, the logic partitions can be automatically distributed to the appropriate paging equipment when using the memory-sharing pool, a user is unnecessary to manually configure the paging equipment, the error probability of the manual configuration is greatly lowered, the maintenance cost is reduced, and the execution efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a paging device management method of a shared memory pool, an electronic device and a storage medium. Background technique [0002] The physical memory of IBM Power System can be assigned to multiple logical partitions in dedicated or shared mode. Shared memory pool (Active Memory Sharing) is an advanced memory virtualization technology of IBM PowerVM, which provides system memory virtualization function to IBMPower Systems and allows multiple logical partitions to share a common physical memory pool. [0003] When using the shared memory mode, the system automatically determines the optimal distribution of physical memory to logical partitions, and adjusts memory allocation based on memory page requirements. The administrator reserves only physical memory for the shared memory pool and assigns logical partitions to the shared memory pool. Shared memory pools can be use...

Problems solved by technology

[0007] That is, when using the shared memory pool function, there are cumbersome and error-prone configuration work

For users who do not understand the function of the PowerVM shared memory pool, they often have no way to start. There are often many problems such as configuration errors, configuration failures, and unclear how to specify a suitable paging device for the partition, which leads to giving up the advanced function of using the shared memory pool.
