| 20090267693 | RESISTOR SELF-TRIM CIRCUIT FOR INCREASED PERFORMANCE - In a method and apparatus for trimming values of load resistors to reduce variations there between, a common mode feedback loop (CMFBL) included in a differential amplifier is switched from operating in a closed loop mode to operate in an open loop mode. The CMFBL includes an operational amplifier (OA) generating an output signal. A selector switch, coupled to receive the output signal, is operable to switch a path of the output signal in response to a CAL signal. In the closed loop mode, the selector switch routes the output signal to a feedback loop to provide a regulated current to the load resistors. In the open loop mode, the OA operates as a comparator and the output signal is provided as a digital signal. The selector switch provides the digital signal to a controller to digitally trim the values of the load resistors. | 10-29-2009 |

| 20110153825 | SERVER RESOURCE ALLOCATION - A method, programmed medium and system are disclosed which provide for end-to-end QoS for a set of processes that comprise a workload over nfs. A set of processes that comprise a workload such as the processes of a WPAR, or an entire LPAR are given a class designation and assigned priority/limits. The data are then passed to the server which allocates resources based on the sum total of all the current classes and their priorities and/or limits. This requires re-engineering the nfs client code to be workload-aware and the nfs server code to accommodate the resource allocation and prioritization needs of the nfs clients. | 06-23-2011 |
