Switch zoning limitations for the IBM Enterprise Storage Server

When you zone the IBMEnterprise Storage Server to the system, consider the following limitations.

To avoid a single point of failure on the IBM Enterprise Storage Server, you must have a minimum of two SAN connections from two separate adapter bays. The maximum number of IBM Enterprise Storage Server SAN connections in the system switch zone is 16.
Note: The IBM Enterprise Storage Server provides ESCON, FICON, and Ultra-SCSI connectivity; however, only a 1 or 2 Gb Fibre Channel SAN attachment is supported by the system.
