Abstract

The invention discloses an NVMe-based multi-path load balancing implementation method. The method comprises the following steps: adding configuration items of bandwidth, IOPS and names in configuration of a server; encoding a character string in the name, and generating a 20-bit hex value; obtaining MAC addresses in a server network card through a server side to form a 12-bit character string, and performing operation; converting the operation result into a 32-system numerical value, and performing block coding to regenerate a new 12-bit character string; combining the new 12-bit character string and the 20-bit hex value to serve as a globally unique name of the disk; and enabling the client to perform reverse analysis on the globally unique name of the disk. The invention has the beneficial effects that the limitation of IOPS and bandwidth on the disk is increased, the user can perform resource isolation of storage performance, and the resource reliability of each user is ensured in a multi-user scene.

Description

technical field [0001] The invention relates to the field of storage protocols, in particular to an implementation method of NVMe-based multipath load balancing. Background technique [0002] Storage is one of the cores of IT hardware infrastructure. With the increasing popularity of SSD based on Flash and the new generation of PCM solid-state storage, the performance of storage is getting higher and higher. At the same time, the density of solid-state storage is getting higher and higher, resulting in superior storage capacity and performance of a single server. For a single application, its value cannot be fully utilized. [0003] SCSI (Small Computer System Interface, small computer system interface) depends on the TCP protocol, and the TCP protocol itself is expensive, so its performance is not good under the usual configuration. iSER is still extended based on the SCSI storage protocol, so the organization of the protocol stack is still limited by the SCSI protocol, s...
