Monitoring Network: Accessibility
Storage networks need to be monitored to ensure proper communication between the server and
the storage array. Uninterrupted access to data over the storage network depends on the
accessibility of the physical and logical components in the storage network. The physical
components of a storage network include switches, ports, cables, and power supplies. The logical
components include constructs, such as zones. Any failure in the physical or logical components
causes data unavailability. For example, errors in zoning, such as specifying the wrong WWN of a

port, result in failure to access that port, which potentially prevents access from a host to its
storage.
