(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 will be designed in thefuture to support
the sharing of CPUs and memories by a number of operatingsystems concurrently.
6.10.1 [30] <§6.4> Select two hypervisorson the market today, and compare
and contrast how they virtualize and manage the underlyinghardware (CPUs and
memory).
6.10.2 [15] <§6.4> Discuss what changesmay be necessary in future multi-core
CPU platforms in order to better match the resource demandsplaced on these
systems. For instance, can multithreading play an effective rolein alleviating the
competition for computing resources?
