    Abstract: A digital system and method of operation is provided in which several processors (400[]) are connected to a shared resource (432). Each processor has a translation lookaside buffer (TLB) (310[]) that contains recently used page entries that each includes an access priority value. Access priority values are assigned to regions of address space, typically pages, according to the program or data that is stored on a given page. Access priority values are maintained in page tables with address translations, such that when a translated page address is loaded into a TLB, the access priority associated with that page is included in the TLB page entry. Arbitration circuitry (430) is connected to receive a request signal from each processor along with an access priority value (353[]) from each TLB in response to the requested address. The arbitration circuitry is operable to schedule access to the shared resource according to the access priority values provided by the TLBs.

    Abstract: A recording medium which is readable by a computer stores a performance analyzing program for searching for a node that is peculiar in performance in a cluster system, as well as unknown problems. The performance analyzing program enables the computer to function as various functional units. A performance data analyzing unit collects performance data of nodes which make up the cluster system from performance data storage unit for storing a plurality of types of performance data of the nodes, and analyzes performance values of the nodes based on the collected performance data. A classifying unit classifies the nodes into a plurality of groups by statistically processing the performance data collected by the performance data analyzing unit according to a predetermined classifying condition. A group performance value calculating unit statistically processes the performance data of the respective groups based on the performance data of the nodes classified into the groups, and calculates statistic values for the respective types of the performance data of the groups. A performance data comparison display unit displays the statistic values of the groups for the respective types of the performance data for comparison between the groups.

    Abstract: System, method and program for managing a storage server comprising first and second clusters of storage controllers. The first cluster comprises one or more storage controllers each controlling one or more storage arrays. The first cluster also comprises a first cache memory and a first nonvolatile storage (“NVS”) shared by the one or more storage controllers of the first cluster. The second cluster comprises one or more storage controllers each controlling one or more storage arrays. The second cluster also comprises a second cache memory and a second nonvolatile storage shared by the one or more storage controllers of the second cluster. There is monitoring of an amount of time that data controlled by each of the clusters is held in the cache memory of the cluster before being outpaged to the storage arrays. There is monitoring of an amount of requests to access storage arrays of a cluster that were delayed due to insufficient NVS. A level of impairment of access to each of the storage arrays is determined based on the amount of time that data controlled by each of the clusters was held in the cache memory of the cluster before being outpaged to the storage arrays, and the amount of requests to access the storage arrays of a cluster that were delayed due to insufficient NVS. When access to a storage array is excessively impaired, data is moved from the access-impaired storage array to another storage array with a lower level of access impairment.
