Method for utilizing accelerator cards to accelerate cluster deployment

Abstract

The invention provides a method for utilizing accelerator cards to accelerate cluster deployment. A plurality of servers where peripheral component interconnect-express (PCI-E) solid-state accelerator cards are installed and rear-end storages of the servers form a completed cluster, data writing services can be performed on a single server at the same moment through corresponding cluster management software, and when the written data quantity of the PCI-E solid-state accelerator cards of a first server reaches 90%-100% of the volume of memory module solid state disks (SSDs) in the PCI-E solid-state accelerator cards, the cluster management software can migrate the data writing services to a second server; and when the data storage quantity in the PCI-E solid-state accelerator cards of the second server reaches the same state, the data writing services are transferred to a next server, and no matter which server the data writing services are positioned in, operation of enabling data in the memory module SSDs in the PCI-E solid-state accelerator cards of each server to be written to a rear-end storage array is not influenced.

Description

technical field [0001] The present invention relates to data storage acceleration technology, in particular to a cluster deployment solution that solves the problem that an accelerator card cannot provide acceleration for continuous high-speed data writing services, or a method for accelerating cluster deployment by using an accelerator card. Background technique [0002] With the explosive growth of digital devices, applications, and content, the demand for high-bandwidth, high-IO applications is increasing. Storage accelerator cards are high-end storage products customized and developed for various high-bandwidth and high-IO applications. Currently common accelerator cards are mainly PCI-E solid-state storage accelerator cards integrated with storage module SSDs. Its main writing acceleration principle is to use the high-speed advantages of the solid-state storage module SSD and the PCI-E standard to temporarily store the data to be written in the solid-state storage mod...

Problems solved by technology

[0003] However, there is a problem that cannot be ignored in the application of storage accelerator cards, that is, it can only be applied to network environments where the amount of data written continuously at high speed is not particularly large.

Because when the amount of data written continuously at high speed is large, the solid-state storage module SSD in the accelerator card will gradually be filled with data and cannot transfer all the data to the disk drive in time, and cannot continue to provide cache space for the data to be written

In this case, external data can only be written to the solid-state storage module SSD after waiting for the data in some solid-state storage module SSDs to be slowly transferred to the disk drive. Therefore, the data writing speed at this time will not be faster than The writing speed of the local disk drive is high, or even lower, and the phenomenon of "stuck" occurs
