represents. In most virtual storage systems a metadata mapping table is held which translates the incoming (virtual)

applications as if it were a physical computer. A virtual machine behaves exactly like a physical computer and

customer's production servers. Server replication, disaster recovery test, and disaster recovery invocation are
automated when selecting the desired options from the portal.
