Switch zoning limitations for the IBM ESS
Consider the following limitations when you zone the IBM® Enterprise Storage Server® (ESS) to the IBM Spectrum Virtualize™.
To avoid a single point
of failure on the IBM ESS, you
must have a minimum of two SAN connections
from two separate adapter bays. The maximum number of IBM ESS SAN connections in the IBM Spectrum Virtualize switch
zone is 16.
Note: The IBM ESS
provides ESCON, FICON® and Ultra SCSI connectivity; however,
only a 1 or 2 Gb Fibre Channel SAN
attachment is supported by the IBM Spectrum Virtualize.
