Embodiment Construction

[0028] The principle of the present invention will be described below with reference to the accompanying drawings.

[0029] figure 1 Represents an outline of a computer. The computer 1 is connected to a source computer 2 , a destination computer 3 , an activation server 4 , and an address management server 5 through a network 6 . The computer 1 includes an operation reception block 1a, an execution information reception block 1b, an address reception block 1c, and a processing block 1d. The source computer 2 and the destination computer 3 have the same functions as the computer 1 .

[0030] The boot server 4 stores operating system programs. When the computer 1, the source computer 2 and the destination computer 3 are started, the address management server 5 assigns them a unique floating MAC address in addition to their own inherent MAC addresses.

[0031] If the process is migrated from the source computer 2 to the computer 1, the operation receiving block 1a of the comp...

Abstract

A migration program which reduces a service suspension time, ensures access transparency and position transparency, and enables normal operation without degrading the performance. When processing is migrated from a source computer, an operating reception block receives an operating system program through a network. An execution information reception block receives execution information needed to resume a process of the source computer, through the network from the source computer. An address reception block receives a floating MAC address assigned to the source computer in addition to the inherent MAC address, from the source computer. A processing block executes processing to restore the state of the source computer in accordance with the received operating system program and execution information, and performs subsequent communication by using the received floating MAC address of the source computer.

Description

technical field [0001] The present invention relates to a migration program, an information processing device, a computer system, and a computer-readable recording medium storing the migration program, and more particularly, to a migration program, an information processing A device, a computer system, and a computer-readable recording medium storing a migration program. Background technique [0002] With the development of computer networks such as the Internet and intranets in recent years, the scale of related servers has been increasing. The increase in the scale of the server makes it necessary to construct a large-scale cluster system, which combines a large number of processor nodes. [0003] Large-scale cluster systems have a high packing density, ie contain a large number of processor nodes in a single physical rack, as seen in so-called blade servers. Some processor nodes share hardware resources. [0004] When a processor node needs to be maintained in such a c...
