business networking
In the previous chapters we have introduced all the necessary techniques for storage
networks. Many of these techniques deal with the virtualisation of storage resources like
RAID, instant copy, remote mirroring, volume manager, file systems, and file system
snapshots. All these business networkingvirtualisation techniques have in common that they present given
storage resources to the upper layers as logical resources which are easier to use and
administrate and which very often are also more performant and more failure tolerant.
The next chapter will discuss how the concept of storage virtualisation changes in a
storage-centric IT architecture.
