System, method, architecture, and computer program product for dynamic power management in a computer system
First Claim
1. In a system having a plurality of physical network devices, a method for grouping said plurality of physical network devices into a logical network device for operation and control, said method comprising:
- coupling said physical network devices that are to be grouped together as a logical device for communication;
identifying a manager to supervise operation of said logical device;
identifying a number of said plurality of physical network devices that are configured to perform a task;
receiving at least one request for performance of the task; and
determining demand for the task; and
based on the demand, executing a procedure within said manager to coordinate and control operation of said logical device to increase or decrease the number of physical network devices that are configured to perform the task.

Abstract
Network architecture, computer system and/or server, circuit, device, apparatus, method, and computer program and control mechanism for managing power consumption and workload in computer system and data and information servers. Further provides power and energy consumption and workload management and control systems and architectures for high-density and modular multi-server computer systems that maintain performance while conserving energy and method for power management and workload management. Dynamic server power management and optional dynamic workload management for multi-server environments is provided by aspects of the invention. Modular network devices and integrated server system, including modular servers, management units, switches and switching fabrics, modular power supplies and modular fans and a special backplane architecture are provided as well as dynamically reconfigurable multi-purpose modules and servers. Backplane architecture, structure, and method that has no active components and separate power supply lines and protection to provide high reliability in server environment.

57. A method of reducing power consumption in a computer system having a mirroring data storage subsystem, said method comprising steps of:
-
selecting a first set of disc drives from among a plurality of sets of disc drives as a currently active set;
selecting a second set of disc drives as a currently inactive set and placing said selected inactive set in a power conserving mode;
using said first set of disc drives to retrieve data in response to read data requests;
activating said second set of disc drives in response to a write data request prior to performing said requested write operation;
performing said write operation to both said first and second set of disc drives; and
selecting one of said first set and second set as the inactive set and deactivating said selected inactive set after performing said write operation. - View Dependent Claims (58, 59, 60, 61)
