Verifying the WAN and the LAN Infrastructure
After the on-site Discover phase, review the collected data for all of the network routers
that will be used for the remote mirroring services.
·
Make sure that sufficient additional bandwidth is available for remote mirroring traffic.
·
Make sure that additional ports are available to connect the storage systems.
·
Determine whether any Quality of Service (QoS) settings are in place.
·
Make sure that the correct IP addressing schema is in place.
·
Review the discovery data for the WAN hardware, if any discovery data exists.
·
Determine the current capabilities of the hardware and whether sufficient bandwidth is
available to support remote mirroring services.
·
Make sure that the equipment is on the supported compatibility list.
·
Make sure that the equipment firmware is current.
