more virtual servers, the only option would be to convert that virtual machine into an actual
server so that it can have access to a powerful CPU, or a whole set of them.
Storage Virtualization Storage virtualization is essentially creating virtual disks from a
large-capacity pool that is a conglomeration of the storage capacity of all the hosts, servers,
and SANs in the system. A single file format is created that the virtual machine can see as
an actual disk. All of the files, operating system, and applications of a virtual machine are
located in this single virtualized storage. It makes a virtual machine very portable because
you only have to copy or transfer this virtual disk file to other environments in order to
have the same virtual machine, provided you have configured for the new virtual machine
to have the same settings as the old one.
