20080244213 | WORKLOAD MANAGEMENT IN VIRTUALIZED DATA PROCESSING ENVIRONMENT - A system, method and computer-readable medium for balancing access among multiple logical partitions to the physical system resources of a computer system employing system virtualization. Each of the logical partitions is classified, initially during a startup period, in accordance with a level of allocated dispatch window utilization. Performance metrics of one or more of the physical system resources are determined in association with one or more of the logical partitions. The performance metrics determination is performed at a hardware level independent of programming interrupts. During a dispatch window in which a given set of the physical system resources are configured for allocation to one of the logical partitions, the given set of physical system resources are re-allocated to a replacement logical partition in accordance with the determined performance metrics associated with the replacement logical partition and the dispatch window utilization classification of the replacement logical partition. | 10-02-2008 |

20080244568 | METHOD TO CAPTURE HARDWARE STATISTICS FOR PARTITIONS TO ENABLE DISPATCHING AND SCHEDULING EFFICIENCY - A method, system and computer program product enables the granular collection and utilization of hardware statistical samples for the efficient scheduling and allocation of data processing resources. In particular, a Partition Statistics Capture and Analysis (PSCA) utility utilizes special purpose registers to collect statistical samples, such as: (1) instructions completed; (2) Level2 (L2) cache misses; (3) cycles per instruction (CPI); and/or (4) other statistics selected based on the programming of the PSCA utility. Further, these statistical samples are utilized for the several purposes, including: (1) determining how long (time) the footprint of a partition takes to become established during the “cold start” period, i.e., during system instantiation; (2) detecting movement of the CPI curve in order to determine the (shifted) location of the onset of steady state (i.e., the knee) on the CPI curve; and (3) utilizing the statistical samples to guide dispatch decisions and make tuning recommendations. | 10-02-2008 |
20090186494 | APPARATUS, SYSTEM, AND METHOD FOR A CONFIGURABLE BLADE CARD - An apparatus, system, and method are disclosed for a configurable blade card. A base card is in physical and electrical communication with a blade connector. The blade connector is in physical and electrical communication with a blade enclosure connector. A secondary card is in physical and electrical communication with the base card to form a blade card. A coupler physically couples the base card and the secondary card. The base card and the secondary card are co-planar and compatible with a blade card form factor. | 07-23-2009 |
20090252057 | WIRELESS SERVICE PROCESSOR CONNECTIONS - A method and system for replacing physical connections within a large enterprise system with wireless connections. A first wireless transceiver is associated with a node, wherein the node comprises one or more system service processors. A second wireless transceiver is associated with a main system service processor. System service processors associated with the node, referred to as node service processors, are assigned a unique identification (ID), e.g., a name and/or number, to identify the node service processors during wireless connection. An Ethernet cable is utilized to connect the node service processors to the main system service processor. The unique identification is transferred from the main system service processor to the node service processor, and then the Ethernet cable is disconnected. When the Ethernet cable is disconnected, the node service processor(s) communicate with the main system service processor via a wireless network utilizing the transceivers and unique IDs. | 10-08-2009 |
20110093861 | Assigning A Portion Of Physical Computing Resources To A Logical Partition - A data processing system includes physical computing resources that include a plurality of processors. The plurality of processors include a first processor having a first processor type and a second processor having a second processor type that is different than the first processor type. The data processing system also includes a resource manager to assign portions of the physical computing resources to be used when executing logical partitions. The resource manager is configured to assign a first portion of the physical computing resources to a logical partition, to determine characteristics of the logical partition, the characteristics including a memory footprint characteristic, to assign a second portion of the physical computing resources based on the characteristics of the logical partition, and to dispatch the logical partition to execute using the second portion of the physical computing resources. | 04-21-2011 |
20120216212 | ASSIGNING A PORTION OF PHYSICAL COMPUTING RESOURCES TO A LOGICAL PARTITION - A computer implemented method includes determining first characteristics of a first logical partition, the first characteristics including a memory footprint characteristic. The method includes assigning a first portion of a first set of physical computing resources to the first logical partition. The first set of physical computing resources includes a plurality of processors that includes a first processor having a first processor type and a second processor having a second processor type. The first portion includes the second processor. The method includes dispatching the first logical partition to execute using the first portion. The method includes creating a second logical partition that includes the second processor and assigning a second portion of the first set of physical computing resources to the second logical partition. The method includes dispatching the second logical partition to execute using the second portion. | 08-23-2012 |
20130091509 | OFF-LOADING OF PROCESSING FROM A PROCESSOR BLADE TO STORAGE BLADES - A processor blade determines whether a selected processing task is to be off-loaded to a storage blade for processing. The selected processing task is off-loaded to the storage blade via a planar bus communication path, in response to determining that the selected processing task is to be off-loaded to the storage blade. The off-loaded selected processing task is processed in the storage blade. The storage blade communicates the results of the processing of the off-loaded selected processing task to the processor blade. | 04-11-2013 |
