Planning Considerations for Fibre Channel Topologies
72 SAN High Availability Planning Guide
■ Consider the data traffic capacity of the department or workgroup (normal and
peak load) as part of the switch planning and installation process.
Such capacity planning:
— Ensures loop traffic is distributed and balanced across servers and storage
devices.
— Identifies traffic bottlenecks and provides for alternate connectivity
solutions if required.
— Assists in calculating scalability to satisfy nondisruptive growth
requirements or eventual connection to a Fibre Channel switched fabric.
Capacity planning is a dynamic activity that must be performed when new
devices, applications, or users are added to the department or workgroup loop
configuration.
