Abstract: Multivariate analysis can be performed to determine whether a computing environment is encountering a business disruption (e.g., relatively long end-user response times) or other problem. Cluster analysis (comparing more recent data with a particular cluster of good operating data), predictive modeling, or other suitable multivariate analysis can be used. A probable cause analysis may be performed in conjunction with the multivariate analysis. A probable cause analysis may be used when one or more abnormal instruments, abnormal components, abnormal load patterns, suspicious actions (such as resource provisioning or deprovisioning activities), software or hardware updates or failures, recent changes to the computing environment (component provisioning, change of a control, etc.), or any combination thereof.

Abstract: An optimal printed circuit board input/output switching system is provided and includes a printed circuit board having multiple input/output ports with communication channels coupling the input/output ports to a switching fabric located thereon. Two printed circuit boards may be connected with a board connector for providing switching between input/output ports of the printed circuit boards in a dual-board switching system. The switching fabrics of each printed circuit board can function as an aggregate switching fabric to provide communication channel switching between the input/output ports of the two printed circuit boards. A dual-board switching system may include a single printed circuit board having the switching fabric located thereon. A board connector facilitates modification of the switching configuration.
