34 Cabling Your Cluster Hardware
c
Connect a cable from Fibre Channel switch 0 (sw0) to the second
front-end fibre channel port on SP-A.
d
Connect a cable from Fibre Channel switch 0 (sw0) to the second
front-end fibre channel port on SP-B.
e
Connect a cable from Fibre Channel switch 1 (sw1) to the third front-
end fibre channel port on SP-A.
f
Connect a cable from Fibre Channel switch 1 (sw1) to the third front-
end fibre channel port on SP-B.
g
Connect a cable from Fibre Channel switch 1 (sw1) to the fourth
front-end fibre channel port on SP-A.
h
Connect a cable from Fibre Channel switch 1 (sw1) to the fourth
front-end fibre channel port on SP-B.
NOTE: Additional cables can be connected from the fibre channel switches to the
storage system if there are available front-end fibre channel ports on the storage
processors.
Zoning Your Dell/EMC Storage System in a Switched Environment
Dell only supports single-initiator zoning for connecting clusters to a
Dell/EMC storage system in a switched environment. When using EMC
PowerPath, a separate zone is created from each HBA port to the SPE.
Connecting a PowerEdge Cluster to Multiple Storage Systems
You can increase your cluster storage capacity by attaching multiple storage
systems to your cluster using a redundant switch fabric. Failover Clusters can
support configurations with multiple storage units attached to clustered nodes. In
this scenario, the Microsoft Cluster Service (MSCS) software can fail over disk
drives in any cluster-attached shared storage array between the cluster nodes.
NOTE: Throughout this document, MSCS is used to refer to either the Microsoft
Windows Server 2003 Cluster Service or the Microsoft Windows Server 2008
Failover Cluster Service.
When attaching multiple storage systems with your cluster, the following
rules apply:
• There is a maximum of four storage systems per cluster.
• The shared storage systems and firmware must be identical. Using dissimilar
storage systems and firmware for your shared storage is not supported.
