DISTRIBUTED BLADE SERVER SYSTEM, MANAGEMENT SERVER AND SWITCHING METHOD

摘要

A distributed blade server system, a management server and a switching method are provided. The method includes: determining a standby blade of a first blade when it is determined that the first blade is in abnormal operation; delivering, based on an access relationship between a startup card of the first blade and a first storage partition, a first configuration command to a storage system, the first configuration command including information of an access relationship between a startup card of the standby blade and the first storage partition, so that the storage system configures the access relationship between the startup card of the standby blade and the first storage partition; and delivering a startup command to the standby blade.

1. A distributed blade server system, comprising:
a management server, a storage system comprising an active storage system and a standby storage system, and a blade server subsystem comprising multiple blades which are mapped to the active storage system, the management server being in connection with the blade server subsystem and the storage system through a network; wherein the management server is configured to:
remove the mapping between all the blades and the active storage system when it is determined that the active storage system is in abnormal operation,to deliver a configuration command to the standby storage system based on a mapping relationship between a blade and a corresponding storage partition in the active storage system, wherein the configuration command comprises information of a mapping relationship between the blade and a corresponding storage partition in the standby storage system, andto deliver a restart command to the blades; wherein the standby storage system is configured to:
save operating system, application program and configuration data that the blades required, andto respond to the configuration command to configure the mapping relationship between the blade and the corresponding storage partition in the standby storage system; wherein the blades is configured to:
respond to the restart command to restart and load, respectively, the operating system, the application program and the configuration data from the corresponding storage partitions in the standby storage system.
