In a storage area network having a host device and a consolidated storage array (CSA), one of the storage arrays of the CSA acts as a primary device of the CSA to form logical data volumes across one or more of the total storage arrays of the CSA. The logical data volumes typically have performance requirements that cannot be met by a single storage array. Upon receipt of a command from the host device to create one of the logical data volumes, the CSA primary device analyzes the storage arrays to determine a combination thereof, across which the logical data volume will be striped, that best satisfies the performance requirements. The CSA primary device configures these storage arrays to form the logical data volume and sends striping information, which defines the logical data volume, to the host device. Striping software based on the host device responds to the striping information to access the logical data volume. The CSA primary device also manages the storage arrays and the logical data volume by monitoring the storage arrays to determine whether any of the storage arrays is about to reach its saturation point, typically due to changing performance requirements of all of the logical data volumes on the storage arrays. The CSA primary device then migrates a portion of one of the logical data volumes from one storage array to another to balance the data transfer loads on the storage arrays.

The design of integrated circuits, i.e., semiconductor products, is made easier with a semiconductor platform having versatile power mesh that is capable of supporting simultaneous operations having different frequencies on the semiconductor product; e.g., higher frequency operations may be embedded as diffused blocks within the lower layers or may be programmed from a configurable transistor fabric above the diffused layers. Preferably the power mesh is located above the layers having the operations requiring the different frequencies, and may be fixed in an application set given to a chip designer or may be configurable by the designer her / himself. For example, to support high speed communications adjacent an embedded high speed data transceiver, the transistor fabric may be programmed as a data link layer having higher performance requirements than the rest of the integrated circuit. The data link layer may be connected to one of the localized grids of the versatile power mesh which may have an increased density and / or wider strap width of a power / ground grid. Additional decoupling capacitance can be embedded in the lower layers of the semiconductor product and / or can be programmed from the configurable transistors fabric.

Described herein are the materials, mechanisms and procedures for optimizing various performance parameters of HPDLC optical devices in order to meet differing performance requirements. These optimization tailoring techniques include control and independent optimization of switchable HPDLC optical devices to meet the demanding requirements of anticipated applications for, inter alia, the telecommunications and display industries.

In a computing system where multiple servers are connected through a network and one or more jobs are run, a power reduction facility of a supervisory server relocates jobs according to predetermined conditions, thereby reducing the amount of power consumed by the computing system. For relocating the jobs, the power reduction facility obtains server-related information such as the power properties of the servers constituting the computing system and job-related information such as performance requirements for the jobs which are run in the computing system, and searches for one or more jobs to be relocated and destination servers, based on these server-related information and job-related information, to the extent that the performance requirements for each job are fulfilled. Based on the search results, the jobs are relocated to the destination servers, and servers on which no job is running, in consequence of the relocation, are powered off.

An integrated circuit includes a plurality of functional blocks. Utilization information for the various functional blocks is generated. Based on that information, the power consumption and thus the performance levels of the functional blocks can be tuned. Thus, when a functional block is heavily loaded by an application, the performance level and thus power consumption of that particular functional block is increased. At the same time, other functional blocks that are not being heavily utilized and thus have lower performance requirements can be kept at a relatively low power consumption level. Thus, power consumption can be reduced overall without unduly impacting performance.

A circuit arrangement and method utilize a plurality of execution units having different power and performance characteristics and capabilities within a multithreaded processor core, and selectively route instructions having different performance requirements to different execution units based upon those performance requirements. As such, instructions that have high performance requirements, such as instructions associated with primary tasks or time sensitive tasks, can be routed to a higher performance execution unit to maximize performance when executing those instructions, while instructions that have low performance requirements, such as instructions associated with background tasks or non-time sensitive tasks, can be routed to a reduced power execution unit to reduce the power consumption (and associated heat generation) associated with executing those instructions.

Systems and methods are disclosed for providing memory channel interleaving with selective power / performance optimization. One such method comprises configuring an interleaved zone for relatively higher performance tasks, a linear address zone for relatively lower power tasks, and a mixed interleaved-linear zone for tasks with intermediate performance requirements. A boundary is defined among the different zones using a sliding threshold address. The zones may be dynamically adjusted, and / or new zones dynamically created, by changing the sliding address in real-time based on system goals and application performance preferences. A request for high performance memory is allocated to a zone with lower power that minimally supports the required performance, or may be allocated to a low power memory zone with lower than required performance if the system parameters indicate a need for aggressive power conservation. Pages may be migrated between zones in order to free a memory device for powering down.

The method is low in feature design complexity, avoids explicit feature extraction, has high classification correctness, and can be applied to communication systems having high recognition performance requirements.

The present invention provides methods for using time domain analysis of NEXT, Return Loss and the like, in conjunction with the application of time or distance referenced limits to verify and determine compliance of the performance requirements of connections in a typical link. Time domain analysis of NEXT, Return Loss data and the like, suitably provides the performance characteristics of a link as a function of time or distance. When coupled with time or distance performance curves for connections, it can be determined if the transmission fault is at a connection or in the cable. The time limit curves for connections can be generated based on the frequency domain performance requirements for connecting hardware of a specific level of performance. The connection time limit curves thus provide an interpretation means to determine if the connection is within performance standards, allowing improved isolation of the fault condition.

A method of controlling operation of a train (T) for passage of the train through a tunnel. The train has a plurality of locomotives (L1-Ln) pulling the train. The position of the lead locomotive relative to the tunnel entrance is determined, as is the amount of time before the train enters the tunnel. Each locomotive is separately configured for passage through the tunnel as a function of performance characteristics of the locomotive and the locomotive's current operating status, as the train approaches the tunnel. Once the train enters the tunnel, the performance characteristics of each locomotive are continually monitored. The performance requirements for one or more of the locomotives are then dynamically changed as a function of conditions within the tunnel and the current performance characteristics of each locomotive. This is done to maintain a sufficient combined performance capability from the locomotives to move the train through the tunnel. Upon exiting the tunnel, the locomotives' full operating capabilities are quickly restored by enhancing their thermal recoveries.
