Recommended Zoning Configuration for Fibre Channel
Consider the following recommendations when setting up a Fibre Channel SAN infrastructure.
● You can zone the host to 1-4 appliances. It is recommended to zone the host to as many appliances as possible to allow
volume migration to and from all appliances.
● Use two separate fabrics. Each fabric should be on a different physical FC switch for resiliency.
● Balance the hosts between the two nodes of the appliance.
● The PowerStore cluster can be shipped with various extension modules for Fibre Channel. If your PowerStore cluster
contains more than one extension I/O module per node, distribute the zoning among all I/O modules for highest availability
and performance.
● Use single initiator zoning scheme: Utilize single-initiator per multiple-target (1:many) zoning scheme when configuring
zoning with a PowerStore cluster.
● Host I/O latency can be severely affected by FC SAN congestion. Minimize the use of ISLs by placing the host and storage
ports on the same physical switch. When this is not possible, ensure that there is sufficient ISL bandwidth and that both the
Host and PowerStore cluster interfaces are separated by no more than 2 ISL hops.

PowerStore supports direct attachment of hosts to the appliances.
