inventory asset management software
shows the interaction between the primary data centre and its backup data
centre based upon the case study 'protection of an important database'. In the case study,
all the measures discussed in this section for protection against the failure of a component
are used.
In the primary data centre all components are designed with built-in inventory asset management software redundancy. The
primary server is connected via two independent Fibre Channel SANs (Dual SAN) to
two disk subsystems, on which the data of the database is stored. Dual SANs have the
advantage that even in the event of a serious fault in a SAN (defective switch, which
floods the SAN with corrupt frames), the connection via the other SAN remains intact.
The redundant paths between servers and storage devices are managed by appropriate
multipathing software.
