Deployment Guide 11
Verify that the following tasks have been completed for your cluster:
• All hardware is installed in the rack.
• All hardware interconnections are set up as shown in Figure 1-1 and listed in Table 1-4.
• All logical unit numbers (LUNs), RAID groups, and storage groups are created on the Dell | EMC
Fibre Channel storage system.
• Storage groups are assigned to the nodes in the cluster.
Before continuing with the following sections, visually inspect all hardware and interconnections for correct
installation.
Fibre Channel Hardware and Software Configurations
• Each node must include the following minimum hardware peripheral components:
– One or two hard drives (36 GB minimum) in the internal hard-drive bay
– Three Gigabit NIC ports
– Two Fibre Channel HBAs
• Each node must have the following software installed:
– Red Hat Enterprise Linux software (see Table 1-1)
– Fibre Channel HBA driver
Each Dell|EMC Fibre
Channel storage system
Two CAT 5e or CAT 6 cables connected to the LAN
One to four optical connections to each Fibre Channel switch; for
example, for a four-port configuration:
• One optical cable from SPA port 0 to Fibre Channel switch 0
• One optical cable from SPA port 1 to Fibre Channel switch 1
• One optical cable from SPB port 0 to Fibre Channel switch 1
• One optical cable from SPB port 1 to Fibre Channel switch 0
Each Dell|EMC Fibre
Channel switch
One to four optical connections to the Dell | EMC Fibre Channel
storage system
One optical connection to each PowerEdge system’s HBA
Each Gigabit Ethernet switch One CAT 5e or CAT 6 connection to the private Gigabit NIC on
each PowerEdge system
One CAT 5e or CAT 6 connection to the remaining Gigabit Ethernet
switch
