• 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. • For more information on zoning best practices, refer to the Networked Storage Concepts and Protocols techbook: https:// support.emc.com/docu33913_Networked-Storage-Concepts-and-Protocols-TechBook.pdf • PowerStore supports direct attachment of hosts to the appliances.
