POWER MANAGEMENT METHOD USING FABRIC NETWORK AND FABRIC NETWORK SYSTEM USING POWER MANAGEMENT METHOD
First Claim
1. A power management method using a fabric network, the power management method comprising:
- monitoring a status of at least one of a number of external interfaces between the fabric network and at least one host, and monitoring a status of at least one of a plurality of internal interfaces between the fabric network and at least one storage device, the at least one host configured to access the at least one storage device through the fabric network;
calculating aggregate information of bandwidths of the plurality of internal interfaces based on the monitoring of the status of the at least one of the number of external interfaces and the at least one host; and
adjusting the bandwidths of the plurality of internal interfaces such that the aggregate information of the bandwidths of the plurality of internal interfaces is within a threshold range, the threshold range being based on a bandwidth of the at least one of the number of external interfaces connected to the at least one host.

Abstract
A power management method includes monitoring a status of an external interface of external interfaces between the fabric network and at least one host, and a status of an internal interface of internal interfaces between the fabric network and at least one storage device of a plurality of storage devices. The power management method further includes calculating aggregate information of bandwidths of internal interfaces of the plurality of storage devices based on the monitoring, the at least one storage device connected to the at least one host. The method further includes adjusting the bandwidths of the internal interfaces such that the aggregate information of the bandwidths of the internal interfaces is within a threshold range, the threshold range based on a bandwidth of the external interface connected to the at least one host.

12. A fabric network system comprising:
-
a fabric network including a plurality of ports, the fabric network configured to support communication between a host and a plurality of storage devices, the plurality of storage devices connected to access the plurality of ports, a monitor configured to, monitor a status of an external interface connected to the host, and monitor statuses of internal interfaces connected to the plurality of storage devices; and a controller configured to, adjust bandwidths of the internal interfaces based on the monitored status of the external interface and the monitored statuses of the internal interfaces such that a bandwidth used by the host is maintained and power consumption of the plurality of storage devices is reduced. - View Dependent Claims (13, 14, 15)
