Embodiment Construction

[0034] figure 1 This is a schematic structural diagram of a storage system provided by an embodiment of the present invention. like figure 1 As shown, a storage system usually includes multiple storage devices, and each storage device is a physical node. For ease of management, the storage system is usually set to a pluggable rack structure, and a storage system includes multiple racks , a rack is provided with a switch and multiple slots, each slot is equipped with a storage device, each storage device is respectively connected to the port of the switch, and connected to the network through the switch, so as to realize distributed storage. Exemplary, figure 1 The storage system includes two racks, and each rack includes 8 slots. The number of ports on the switch is not less than the number of slots in the rack where the switch is located. Optionally, each rack may be further divided into multiple layers, and each layer is provided with a switch and multiple slots. In thi...

Abstract

The embodiment of the invention provides a method and a device used for acquiring positioning mapping relations of physical nodes in a storage system. The method comprises steps that first mapping relations among identities and media access control addresses of various physical nodes are acquired; second mapping relations among the media access control addresses of the various physical nodes and switch ports are acquired; the physical networking rule of the storage system is acquired, and comprises third mapping relations among the switch ports and physical slots; and according to the first mapping relations, the second mapping relations, and the third mapping relations, fourth mapping relations among the identities of the various physical nodes and the physical slots are acquired, and areused for the positioning of the various physical nodes. The manual recording of the mapping relations among the identities of the various physical nodes and the physical slots is prevented, and therefore heavy workload, low efficiency, and high error rates are prevented.

Description

technical field [0001] Embodiments of the present invention relate to computer technologies, and in particular, to a method and device for obtaining a location mapping relationship of physical nodes in a storage system. Background technique [0002] With the development of computer technology, the ability of computers to transmit, process and store data has gradually increased, resulting in a rapid increase in the amount of data. To meet the requirements of data capacity and reliability, users usually use massive cluster storage systems that support big data for data storage. Cluster storage systems usually adopt a fully symmetric distributed architecture, including thousands or even tens of thousands of physical nodes. A common cluster storage system includes multiple racks, one rack is provided with multiple slots, each slot is inserted with a storage device as a physical node, and each storage device is connected to the network through a switch interface. middle.
