A method for efficient utilization of centralized storage in cloud platform

Abstract

The invention relates to the field of cloud computing, in particular to a method for efficiently utilizing centralized storage in a cloud platform. The method comprises the following steps: logging into centralized storage equipment through a management network, performing LUN (Logical Unit Number) partitioning on the centralized storage equipment, and providing storage resources outwards according to LUNs by means of an SAN (Storage Area Network); finding and logging into LUN equipment on the physical node of each centralized storage resource to be used, and localizing the LUN equipment; creating a logical volume group on one of the nodes by using the localized storage equipment, and sharing the volume group between the node and other nodes; creating a virtual machine; and realizing free expansion management of the capacity of the logical volume group in which a virtual machine disk and a disk are positioned through an LVM (Logical Volume Manager) mechanism. Through the method for easily and efficiently utilizing the centralized storage in the cloud platform provided by the invention, a high-performance virtual machine can be created.

Description

technical field [0001] The invention relates to the field of cloud computing, in particular to a method for efficiently utilizing centralized storage in a cloud platform. Background technique [0002] In the environment of cloud computing and big data, in order to save a large amount of data that has increased rapidly, the storage space provided by the storage devices produced by various storage manufacturers is generally very large, reaching PB or even EB level; while each node in the cloud computing environment The required storage space depends on the situation, and is generally less than TB level, so a solution is needed to reasonably allocate large-capacity centralized storage to nodes for use. [0003] The current general method is to divide the large space of centralized storage into LUNs (LogicalUnit Numbers) of different sizes, and then mount each LUN to each node separately. After the nodes obtain their respective LUNs, format and mount them. load to use. This me...
