5.4.3 Performance The Performance pane reports the general system statistics that relate to processor (CPU)  utilization, host and internal interfaces, volumes, and MDisks. You can switch between MBps  or IOPS, or even drill down in the statistics to the node level. This capability might be useful  when you compare the performance of each node in the system if problems exist after a node  failover occurs. See Figure 5-34. The performance statistics in the GUI show, by default, the latest 5 minutes of data. To see  details of each sample, click the graph and select the time stamp, as shown in Figure 5-35. The charts that are shown in Figure 5-35 represent 5 minutes of the data stream. For in-depth  storage monitoring and performance statistics with historical data about your SVC system,  use IBM Spectrum Control (enabled by former IBM Tivoli Storage Productivity Center for Disk  and IBM Virtual Storage Center) or IBM Storage Insights. This menu provides an overview of currently running tasks triggered by the administrator. In  contrast to the Running jobs and Suggested tasks indication in the middle of the top pane, it  does not list the suggested tasks that administrators should consider performing.  5.4.4 Background tasks Figure 5-34 Performance statistics of the SVC Figure 5-35 Sample details 174  Implementing the IBM System Storage SAN Volume Controller with IBM Spectrum Virtualize V8.2.1
