Problems solved by technology

In a virtualized system, such as figure 1 As shown, the local disk of the server is used by the node of SDS through RDM (Raw Device Mappings, Raw Disk Mapping). The intermediate software layer between them can allow multiple operating systems and applications to share hardware). When the SDS created in this way is used by a virtual machine, it can support the normal operation of the virtual machine business. However, for business scenarios with high performance requirements, Disk performance needs to be improved

Abstract

The invention discloses a virtualization system, which comprises a plurality of virtual machines distributed on a plurality of servers, a software-defined storage SDS system comprising a plurality ofSDS nodes, wherein each SDS node corresponds to one of the plurality of servers; wherein the SDS node is used for executing corresponding read-write operation on a disk corresponding to the SDS node by adopting a disk array RAID card straight-through mode when receiving a read-write operation instruction sent by a virtual machine, and feeding back an operation result to the virtual machine; wherein the disk corresponding to the SDS node is one or more local disks in the local disks included in the plurality of servers. Through the scheme of the invention, the SDS node disk in the virtualization system adopts the disk array RAID card straight-through mode to execute the read-write operation, and the use performance of the SDS disk in the virtualization system is improved.

Description

technical field [0001] The invention relates to the field of cloud computing, in particular to a virtualization system and a method for using SDS node disks in the virtualization system. Background technique [0002] With the rapid development of current storage virtualization and virtualization technology, software-defined storage SDS (Software Defined Storage, software-defined storage) has gradually become an important part of the storage virtualization field. The use of software-defined storage abandons the original physical storage device, and puts the typical storage controller and other functions in the storage hardware into the software layer for realization. In the virtualization system, the local disk provided by the server is used to realize the adapter, shared storage, etc. Features. In a virtualized system, such as figure 1 As shown, the local disk of the server is used by the node of SDS through RDM (Raw Device Mappings, Raw Disk Mapping). The intermediate so...
