Abstract

A server device having a server module and a cooling fan in a chassis includes: a single management unit configured to control the server module and the cooling fan; and a monitoring unit configured to monitor the running status of the management unit. The monitoring unit is configured to execute thermal control of the inside of the chassis on the basis of the result of monitoring of the management unit.

First claim

The invention claimed is:

1. A server device having a server module and a cooling fan in a chassis, the server device comprising:
a management unit configured to control the server module and the cooling fan; and
a monitoring unit configured to monitor a running status of the management unit, the monitoring unit being different from the management unit and having a limited function compared to a function of the management unit,
wherein the monitoring unit is configured to execute thermal control of an inside of the chassis based on a result of monitoring of the management unit, and
wherein the monitoring unit is configured to execute temperature control on the server module based on a result of the monitoring.

2. The server device according to claim 1 , wherein the monitoring unit is configured to control a number of rotations of the cooling fan on a basis of a result of monitoring of the management unit.

3. The server device according to claim 1 , wherein the monitoring unit is configured to execute control to increase a number of rotations of the cooling fan when it is determined that there is a failure in the management unit on a basis of a result of monitoring of the management unit.

4. The server device according to claim 1 , wherein the monitoring unit is configured to execute control to put an upper limit on power consumed by the server module on a basis of a result of monitoring of the management unit.

5. The server device according to claim 1 , wherein:
the monitoring unit is configured to, when it is determined that there is a failure in the management unit on a basis of a result of monitoring of the management unit, give notification of the failure to the server module; and
the server module is configured to put an upper limit on power consumed thereby on a basis of the notification.

6. The server device according to claim 5 , comprising a plurality of server modules,
wherein each of the server modules puts an upper limit on power consumed thereby in accordance with a predetermined degree of priority.

7. The server device according to claim 5 , wherein the server module has a temperature measurement part configured to measure a temperature and is configured to, when receiving notification from the monitoring unit, put an upper limit on power consumed thereby on a basis of a result of measurement by the temperature measurement part.

8. The server device according to claim 5 , wherein the server module is configured to obtain load information showing a load on the server module itself and is configured to, when receiving notification from the monitoring unit, put an upper limit on power consumed by the server module itself on a basis of the load information.

9. A server control method executed by a server device having a server module and a cooling fan in a chassis, the server device including a management unit configured to control the server module and the cooling fan, the server control method comprising:
monitoring, by a monitoring unit, a running status of the management unit, the monitoring unit being different from the management unit and having a limited function compared to a function of the management unit,
executing thermal control of an inside of the chassis on a basis of a result of monitoring of the management unit, and
executing temperature control on the server module based on a result of the monitoring.

10. A non-transitory computer-readable medium storing a program comprising instructions for causing a server device having a server module and a cooling fan in a chassis to realize:
a management unit configured to control the server module and the cooling fan; and
a monitoring unit configured to monitor a running status of the management unit, the monitoring unit being different from the management unit and having a limited function compared to a function of the management unit,
wherein the monitoring unit is configured to execute thermal control of an inside of the chassis based on a result of monitoring of the management unit, and
wherein the monitoring unit is configured to execute temperature control on the server module based on a result of the monitoring.
