computer hardware
Virtualisation in the main memory can either take place within the operating system
in the volume manager or in low-level applications such as file systems or databases
(computer hardware). Like all virtualisation locations described previously, virtualisation in the
volume manager takes place at block level; the structure of the data is not known.
However, in virtualisation in the volume manager the cost for the virtualisation is fully
passed on to the computer: internal and external buses in particular are now more heavily
loaded. On the other hand, the CPU load for volume manager mirroring can generally be
disregarded.
