This thesis describes the exploration and description of the storage spaces and the implementation of storage spaces failover. The initial introduction is followed by the description of storage spaces and the way they function. It describes the components of storage spaces, how they function and what are they made of. Storage is the foundation of any failover system. Without storage there are no services to be provided and data becomes unavailble. Furthermore, thesis describes how to prepare storage pools, virtual disks and volumes. Such a system is available to all users as it is financially sound and reliable. Resiliency types which are used in creating virtual disks are described in full detail. The elements of which failover clusters are made of are described in detail. The method of making the failover cluster with associated storage spaces is described and illustrations show its implementation. Reliability, cost effectiveness, easy implementation and administration are the key guidelines for further development of storage spaces-a.
