(Solved) : 610 Virtualization Software Aggressively Deployed Reduce Costs Managing Today S High Perfo Q36852144 . . . .

6.10 Virtualization software is beingaggressively deployed to reduce the costs of

managing today’s high performance servers. Companies likeVMWare, Microsoft

and IBM have all developed a range of virtualization products.The general concept,

described in Chapter 5, is that a hypervisor layer can beintroduced between the

hardware and the operating system to allow multiple operatingsystems to share

the same physical hardware. The hypervisor layer is thenresponsible for allocating

CPU and memory resources, as well as handling services typicallyhandled by the

operating system (e.g., I/O).

Virtualization provides an abstract view of the underlyinghardware to the hosted

operating system and application soft ware. Th is will requireus to rethink how

multi-core and multiprocessor systems
