In computer science, memory virtualization decouples volatile random access memory (RAM) resources from individual systems in the data centre, and then aggregates those resources into a virtualized memory pool available to any computer in the cluster. Explain memory and storage virtualization? Storage virtualization is the process of grouping the physical storage from multiple network storage devices so that it looks like a single storage device. The only limit is the number of bits in a storage address. These are: Private Virtual Disk: is used by one client only like that of a local hard disk. At the operating system level, a page cache can utilize the pool as a very large memory resource that is much faster than local or networked storage. It replaces controllers and takes over at the disk level. In the approach, the virtualization is done at the host level, where we present the user with virtual storage with different capacity sets where the hosts are multiple, irrespective of whether the end-user is using a virtual machine or a personal computer that accesses the cloud storage. 6 Configuring and Managing Virtual Storage Found inside – Page 413.2.2 Virtualization of Resources In a computer system, different resources can be virtualized.

Virtualization is the "creation of a virtual (rather than actual) version of something, such as a server, a desktop, a storage device, an operating system or network resources".. Software on the memory pool nodes (servers) allows nodes to connect to the memory pool to contribute memory, and store and retrieve data. In this case, the operating system connects to the memory pool, and makes pooled memory available to applications. The most common example of virtualization is partitioning a hard disk during OS installation, where the physical hard drive is split into multiple logical disks to provide better data storage and retrieval (a category known as 'data virtualization'). With both physical and virtual assets demanding memory resources, there is a need to claim, release and reclaim memory in a variety of ways.
