New workloads (mobile, analytics and cloud) are placing heavy demands on information infrastructure (systems, storage, networks and related software). As a result, Quality-of-Service (QoS – latency/response times, performance, security, reliability and more) is being heavily tested. Further, the management and troubleshooting of complex, virtualized, heavy input/output (I/O) environments using human labor only has become almost impossible. There are just too many data points to analyze; too many speeds and feeds to examine; too many information systems layers (systems, storage, networks, operating environments, middleware, applications, databases, etc.) to handle.
