San-Attached Cabling - Dell PowerVault MD3600f Configuration Manual

Figure 7. Four Host Servers With Single-Port HBAs Connected to a Dual-Controller
(Duplex) Storage Array Using Cluster Cabling
PowerVault MD3600f series storage array
Figure 7 shows a four-cluster node connected to two RAID controller
modules. Since each cluster node has redundant paths, loss of a single path
still allows access to the storage array through the alternate path.

SAN-Attached Cabling

SAN-attached cabling configurations provide the highest level of redundancy
and alternate-path connectivity between the host server and storage array. A
SAN configuration using a Fibre Channel compatible switch fabric allows you
to establish multiple redundant paths to data on the storage array.
NOTE:
A SAN configuration using a supported Fibre Channel switch hardware is
required if the Remote Replication premium feature is activated on the storage
array. Remote Replication is not supported in a direct-attached configuration. For
specific cabling requirements for Remote Replication, see "Remote Replication
Cabling Example" on page 19.
