Cabling a SAN-Attached Cluster to an MD36
The cluster nodes attach to the storage system using a redundant switch
fabric and Fibre optic cables with duplex LC multimode connectors.
The switches, the HBA ports in the cluster nodes, and the RAID controller
module ports in the storage system use duplex LC multimode connectors.
The connectors consist of two individual fibre optic connectors with indexed
tabs that must be inserted and aligned properly in the small form-factor
pluggable (SFP) module connectors on the Fibre Channel switches and the
connectors on the cluster nodes and storage systems.
Each HBA port is cabled to a port on a Fibre Channel switch. One or more
cables connect from the outgoing ports on a switch to a RAID controller
module on an MD36x0f storage system.
NOTE:
Adding more cables from the storage system to the switches can increase
the I/O bandwidth and high availability of data.
Figure 2-8 illustrates a method for cabling a SAN-attached cluster to an
MD36x0f storage system.
Cabling a SAN-Attached Cluster to the MD36x0f Storage System
1 Connect cluster node 1 to the SAN:
Connect a cable from HBA port 0 to the Fibre Channel switch (Switch
a
fabric A).
Connect a cable from HBA port 1 to the Fibre Channel switch (Switch
b
fabric B).
2 Repeat step 1 for each additional cluster node.
3 Connect the storage system to the SAN:
Connect a cable from Fibre Channel switch (Switch fabric A) to the
a
Fibre Channel port on the MD36x0f RAID controller module 1, port
In-1.
Connect a cable from Fibre Channel switch (Switch fabric A) to the
b
Fibre Channel port on the MD36x0f RAID controller module 1, port
In-3.
Connect a cable from Fibre Channel switch (Switch fabric A) to the
c
Fibre Channel port on the MD36x0f RAID controller module 0, port
In-0.
