Selecting and reassigning a blade for a logical partition for service scheduling of a blade server

The present invention discloses a blade server and a service scheduling method of the blade server. The method includes the following steps. According to the requirement for processing capability of a service, a blade is selected for a logical partition storing the service data (A1); an identifier of the logical partition storing the service data is issued to the selected blade (A2); the blade starts the service from the logical partition corresponding to the identifier of the logical partition (A3), realizing the dynamic distribution of blades according to the service requirement, and enabling a high-performance blade to be selected at the peaks of the service, so as to ensure that the service is processed normally; while at the valleys of the service, a blade having relatively low performance is used to release the high-performance blade for processing other services.
