System and method for activity or event base dynamic energy conserving server reconfiguration
First Claim
1. An information processing system comprising:
- a frame or enclosure for mounting a plurality of devices;
a backplane having a plurality of backplane electrical connectors disposed within said frame or enclosure;
a plurality of devices, each including a device electrical connector, matingly coupled to said backplane electrical connectors, said plurality of devices including at least one network device for coupling said system with an external network, wherein said at least one network device is configured to operate in a first mode having a first maximum performance level and a first power consumption rate, and a third mode having a third maximum performance level lower than said first maximum performance level and a third power consumption rate lower than said first power consumption rate; and
a power manager disposed within said frame or enclosure and coupled to said at least one network device, said power manager being configured to determine an operating mode for said at least one network device selected from said first and third modes based on predetermined policies, and to direct said at least one network device to operate in said determined operating mode;
and further wherein said network device includes a processor and said system further includes an activity monitor configured to detect a level of activity of said processor, said activity monitor configured to monitor network layer activity in the form of TCP/IP protocol data packets, and the performance of the processor is incrementally lowered by said power manager using said mode control until data packets start dropping indicating that the processor performance is at the limit of adequacy and then increasing the processor performance by a specified increment to act as a safety margin to provide reliable communication of the packets.

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.
