Embodiment Construction

[0014] refer to figure 1 Shown is a structure diagram of a preferred embodiment of the disk array card expansion management system of the present invention. The disk array card (RAID Card) expansion management system 10 runs in the server 1 or other electronic devices. The server 1 also includes a motherboard 2 , on which one or more disk array cards 20 are inserted, and the one or more disk array cards 20 are connected to a bus interface 40 . In this embodiment, the bus interface 40 is a PCI Express (PCI-E) bus interface.

[0015] In addition, each disk array card 20 corresponds to a MIO (Multi Input Output, differential signal input and output) interface 30 , which are connected in series through cables or other connection methods to communicate with each other and share computing loads.

[0016] refer to figure 2 Shown is a functional block diagram of a preferred embodiment of the disk array card expansion management system of the present invention.

[0017] The disk a...

Abstract

A disk array card extension managing method includes: calculating the theoretical percentage of the operation load of each disk array card according to the number of the detected disk array cards; acquiring the current actual percentage of the operation load of each disk array card, sensing the current PCI-E frequency width of each disk array card, transferring the operation data in the disk array cards with high actual percentage to other disk array cards with low actual percentage for processing by differential signals through an MIO interface, and transferring the data transmitted in the disk array cards with saturated PCI-E frequency width to other disk array cards with unsaturated PCI-E frequency width. The invention further provides a disk array card extension managing system. By the method and the system, the frequency width flow and operation load of multiple disk array cards can be adjusted.

Description

technical field [0001] The present invention relates to a cloud computing method and system, in particular to a disk array card expansion management method and system in cloud computing. Background technique [0002] With the rise of cloud computing, many enterprise servers and data center architectures have adopted the storage design, so that more than hundreds of hard disks exist in one host at the same time, and hundreds of hard disks are combined into multiple A RAID (Redundant Arrays of Inexpensive Disks, Redundant Array of Independent Disks) can be used by many users at the same time. At this time, the computing power of the disk array card (RAID Card) and the bandwidth of the connected PCI Express interface will not be able to bear such a large demand at the same time. Contents of the invention [0003] In view of the above, it is necessary to provide a disk array card expansion management method that can adjust the bandwidth flow and computing load of multiple dis...
