Abstract

In a server system, functions of blade servers can be visually recognized at a glance. A change in load due to a failure can be detected to modify the system configuration by changing functions of blade servers. The server system includes a blade system including servers having different function types, the servers being installed in one or more stages in one enclosure, and a managing server for managing the blade system. The managing server includes a first managing section for classifying the servers into groups, a second managing section for managing a state of arrangement of the servers in the enclosure, and an arrangement changing section for changing functions of the servers discretely and for changing arrangement of the servers in the enclosure by replacing functions of the servers. The arrangement changing section arranges the servers in the enclosure on a function basis of the servers.

Claims

1. A server system, comprising:

a blade system including a plurality of servers, the servers being installed in one or more stages in one enclosure and including servers of different function types; and

a managing server for managing the blade system,

wherein the managing server changes a function of each of the servers.

2. The server system according to claim 1, wherein at change of a function of a server, the managing server delivers an image collected in the system or an image beforehand obtained to a server to thereby change the function of the server.

3. The server system according to claim 1, wherein the managing server is one of the servers of the blade system.

4. A server system, comprising:

a blade system including a plurality of servers, the servers being installed in one or more stages in one enclosure and including servers of different function types; and

a managing server for managing the blade system, wherein;

the managing server includes a first managing section for classifying the servers into groups to thereby manage the servers, a second managing section for managing a state of arrangement of the servers in the enclosure, and an arrangement changing section for changing functions of the servers discretely and for changing arrangement of the servers in the enclosure by replacing functions of the servers, and

the arrangement changing section arranges the servers in the enclosure in blocks on a function basis of the servers.

5. The server system according to claim 4, wherein:

the managing server includes a load state monitoring section for monitoring a state of load on each of the servers; and

the load state monitoring section activates the arrangement changing section when a failure occurs in one of the servers and loads on servers having a same function as the failed server becomes larger than a reference value.

6. The server system according to claim 4, wherein:

the managing server is connected to a display; and

the display is used to display a state of arrangement of the servers in the enclosure in different colors for the functions of the servers.

7. The server system according to claim 4, wherein each of the servers in the blade system includes a lighting section of a color corresponding to the function thereof.

8. A server arrangement method for use in a server system comprising:

a blade system including a plurality of servers, the servers being installed in one or more stages in one enclosure and including servers of different function types; and

a managing server for managing the blade system, the method executed by the managing server comprising the steps of;

classifying the servers into groups to manage the servers;

managing a state of arrangement of the servers in the enclosure; and

changing functions of the respective servers discretely and changing arrangement of the servers in the enclosure by replacing functions of servers,

whereby, through the arrangement change by the managing server, the servers are arranged in the enclosure in blocks on a function basis of the servers.

9. The server arrangement method according to claim 8, the method of executed by the managing server further comprising the steps of:

monitoring a state of load on each of the servers; and

replacing functions of servers, when a failure occurs in one of the servers and load on servers having a same function as the failed sever becomes larger than a reference value.

10. A storage device medium for storing on a computer-readable medium a program to execute the server arrangement method according to claim 8.
