Workload-to-Resources Mapping
Having described the resources and workload managed by the N1 Grid OE, it is now appropriate to explore how the workload is mapped onto the resources. In a traditional system, the operating system scheduler, memory manager, and device driver components map workloads onto processors, memory, and I/O resources based on simple policies. The operating system virtualizes the underlying resources and provisions the workloads onto them. In an N1 Grid system, virtualization and provisioning are also fundamentally important mechanisms that enable the N1 Grid OE to map workload onto resource.
Today, both terms are used to describe work being undertaken to solve the data center management problems enumerated in Chapters 1
