Embodiment 1

[0040] Such as figure 1 , image 3 Shown, a kind of high-performance mass storage system of the present invention, mass storage system comprises file server and network disk array group, and network disk array group comprises multiple network disk arrays, and all network disk arrays are connected through peripheral channel by DAS mode Connected to the file server, and then all network disk arrays and file servers are connected to the switching network through network channels; network users are connected to the switching network, and network users interact with file servers and network disk arrays through the switching network; the file server is responsible for Monitor all operations in the mass storage system, and provide data description for network users; network disk array is responsible for data access of network users; peripheral channel is SCSI bus or FC bus or network channel.

[0041] The software structure in the mass storage system is divided into three levels: ch...

Embodiment 2

[0046] A high-performance mass storage system of the present invention, the mass storage system includes a file server and a network disk array group, the network disk array group includes a plurality of network disk arrays, and all network disk arrays are connected to the file system through a peripheral channel in a DAS manner. On the server, all network disk arrays and file servers are connected to the switching network through network channels; network users are connected to the switching network, and network users interact with file servers and network disk arrays through the switching network; the file server is responsible for monitoring the massive All operations in the storage system, and provide data description for network users; network disk array is responsible for data access of network users; peripheral channel is SCSI bus or FC bus or network channel.

[0047] The software structure in the mass storage system is divided into three levels: channel control layer, ...

Embodiment 3

[0055] Such as figure 2 As shown, a high-performance mass storage method of the present invention uses a mass storage system to store data, and the file organization method is divided into two types:

[0056] (1) Independent file organization mode: network disk array is an independent storage unit, each network disk array has a separate directory node on the file server, and different file systems can be established on each directory node to store different types of files. Files (such as audio-visual, text, etc.), and each handle network user data access and network transmission; when network users send requests to different directory nodes, multiple requests can be served in parallel on multiple network disk arrays;

[0057] (2) Distributed file organization method: the storage space on the storage nodes of multiple network disk arrays is virtualized into a single logical view of the storage space, and the data is stored in blocks on multiple storage nodes; When a small amo...

Abstract

The invention discloses a high-performance mass storage system and a high-performance mass storage method, and belongs to the technical field of storage. The mass storage system comprises a file server and a network disk array group, wherein the network disk array group comprises a plurality of network disk arrays, all network disk arrays are mounted onto the file server through a peripheral channel in a DAS mode, and then, all network disk arrays and the file server are connected onto a switching network through network channels; a network user is connected onto the switching network, and realizes interaction with the file server and the network disk arrays through the switching network; the file server is in charge of monitoring all operations in the mass storage system and provides data description for the network user; the network disk arrays are in charge of the data access of the network user; and the peripheral channel is an SCSI bus or an FC bus or a network passage. The high-performance mass storage system and the high-performance mass storage method have the beneficial effects that the advantages of a centralized storage system and a distributed storage system are simultaneously achieved, and the file centralized management and the data distributed storage are realized.

Description

[0001] technical field [0002] The invention relates to the technical field of storage, in particular to a high-performance mass storage system and a storage method. Background technique [0003] The rapid development of modern information technology has led to the explosive growth of users' demand for storage products and storage services. The performance of the current computer storage system is far from meeting the needs of many practical applications, so how to build a high-performance storage system has become the focus of attention. [0004] However, the network requests of traditional mass storage systems adopt a server-centered circuitous transmission mode, that is, all network requests are managed by the server in a unified manner, resulting in the data flow being transmitted and forwarded back and forth between the server and the storage device. There is a potential bottleneck in the / O bus, which greatly affects the system bandwidth and the average response spee...
