Chapter 2: Planning for Using Disk S helves with a Gateway 19
topology Disk shelves are directly
connected to the gateway
through a loop-based
technology. The gateway is connected a
storage array either directly or
through a Fibre Channel
switched fabric.
gateway neighborhood The concept of gateway
neighborhood does not apply to
native disk shelves attached to a
gateway. However, when disks
are attached to a system in the
neighborhood that uses both
disks and array LUNs, you must
count the disks toward the
visible limit. See the gateway
Installation Requirements and
Reference Guide
for more
information.
All gateways in the
neighborhood see each other’s
array LUNs.
gateway FC ports Gateway FC ports must be set as initiators to access storage on native
disk shelves and array LUNs.
