Embodiment Construction

[0039] refer to figure 1 Shown is the architecture diagram of the communication system in the embodiment of the present invention. The communication system includes a host, a switching network, and a storage system. The storage system includes at least one hard disk enclosure and at least one control enclosure. A hard disk enclosure includes at least two cascaded boards , a control box includes at least two controllers; and the storage system can be in a disk-control integrated mode or an independent machine head mode.

[0040] The embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0041] refer to figure 2 As shown, the storage system includes a first hard disk enclosure 1 and a first control enclosure 2. The first hard disk enclosure 1 is connected to the first control enclosure 2 through a PCIE bus. The first control enclosure 2 includes a first controller 20. The first hard disk enclosure 1 incl...

Abstract

The invention discloses a storage system and a communication method. According to the method, when a first host interface card in a first hard disc frame receives a first I / O request sent by an upper-layer host, the first I / O request is sent to a first control frame through a PCIE bus, and the first control frame processes the first I / O request. According to the technical scheme, the first host interface card is added in the first hard disc frame, the first host interface card in the first hard disc frame receives the first I / O request sent by the upper-layer host, and therefore the number of host interfaces in the storage system can be increased. Along with increasing of the number of hard disc frames, the number of host interfaces can be increased smoothly, no new device needs to be added, and cost and device transformation complexity in the process of expanding the number of of the host interfaces of the storage system are effectively reduced.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a storage system and a communication method. Background technique [0002] At present, for the host in the communication system, its storage space is a fixed value. When the amount of data to be processed by the host is relatively large, the size of the host storage space will become an important factor restricting the data processing capability of the host. [0003] In order to increase the storage space of the host, a storage system is usually installed outside the host, and the storage system is used as a peripheral storage unit of the host, and data interaction between the storage system and the host is realized through a switching network. The above-mentioned storage system includes a hard disk enclosure and a control enclosure. The hard disk enclosure is used to store all the hard disks storing data. The hard disk enclosure includes hard disk interfaces for interconnection wi...
