Quick failover of blade server

摘要

Failover process for switching from a “failing” blade server to a “replacing” blade server. This process includes the following steps: (i) booting a replacing blade server to a set of operating system(s) including a first operating system; and (ii) subsequent to the booting of the replacing blade server, sending command data to the replacing blade server. The command data includes a command for the replacing blade server to configure itself to replace the failing blade server.

主权项

1. A computer program product for controlling, at least a portion of, a failover from a failing blade server to a replacing blade server, the computer program product comprising software stored on a non-transitory software storage device, the software comprising:
first program instructions programmed to boot a replacing blade server to a set of operating system(s) including a first operating system; second program instructions programmed to receive, by the replacing blade server, command data while the replacing blade server is in a booted state; and third program instructions programmed to, responsive to the command data, configure the replacing blade server to replace the failing blade server without any rebooting of the replacing blade server; wherein: the software is stored on a software storage device in a manner less transitory than a signal in transit; and the third program instructions are located in an adaptation layer of the replacing blade server.
