HP 3PAR T-Class Installation and Deinstallation Guide

F Fibre Channel Adapter Installation Order
This appendix describes the Fibre Channel adapter installation order for T-Class storage system
controller node hardware upgrades. Use this appendix to determine which PCI slots to use for
installing additional Fibre Channel, iSCSI, and Ethernet adapters.
Three types of adapters are used in a T-Class system:
• Fibre Channel adapters. External connections to some hosts as well as all internal connections
between controller nodes and drive chassis require the use of Fibre Channel adapters. Fibre
Channel adapters have four ports (quad-port adapters).
• iSCSI adapters. T-Class nodes can optionally use iSCSI adapters for host connections.
• Ethernet adapters. HP 3PAR Remote Copy using Ethernet requires one pair of Ethernet adapters
in the primary system and another pair of Ethernet adapters in a backup or target storage
system.
There are six PCI slots to hold a maximum of six adapters each (Figure 121 (page 210)).

Table 31 (page 211) summarizes the adapter installation order for T-Class controller nodes. Numbers
denote PCI slots (see Figure 121 (page 210)) and numbers in parentheses denote PCI slots to be
used only when necessary.
