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, and a blade server subsystem comprising multiple blades, 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:
determine a standby blade of a first blade when it is determined that the first blade is in abnormal operation,to deliver, based on an access relationship between a startup card of the first blade and a first storage partition, a first configuration command to the storage system, wherein the first configuration command comprises information of an access relationship between a startup card of the determined standby blade and the first storage partition,to deliver a startup command to the determined standby blade,to save system configuration data, wherein the system configuration data comprises a blade startup card identification, a storage partition identification, and a blade state that has a mapping relationship,to monitor a state of the active storage system,to remove a mapping relationship between a blade and the active storage system when detecting that the active storage system is in abnormal operation,to deliver a second configuration command to the standby storage system based on a mapping relationship between a startup card identification of the blade and a corresponding storage partition identification in the active storage system, wherein the second configuration command comprises information of a mapping relationship between the startup card identification of the blade and a corresponding storage partition identification in the standby storage system, andto deliver a restart command to the blade; wherein the storage system comprises multiple storage partitions, an active storage system, and a standby storage system and is configured to:
save an operating system, an application program and configuration data that are required by the multiple blades, andto respond to the first configuration command to configure the access relationship between the startup card of the standby blade and the first storage partition, so as to enable the standby blade to access the first storage partition; wherein the standby blade is configured to:respond to the startup command, andafter the startup card of the standby blade is started, to load, from the accessible first storage partition in the storage system, the operating system, the application program and the configuration data; wherein the standby storage system is configured to:
respond to the second configuration command to configure the mapping relationship between the startup card identification of the blade and the corresponding storage partition identification in the standby storage system; and wherein the blade is further configured to: respond to the restart command, and after the startup card of the blade is started, to load the operating system, the application program and the configuration data from a storage partition in the standby storage system identified by the storage partition identification associated with the startup card identification.
