PCI Slot Installation Order
The exact order for installing Fibre Channel adapters into the PCI slots of T-Class nodes depends
on the number of adapters used and the types of connections required (host or drive cage). In
addition, the presence of iSCSI and Ethernet adapters can impact the use of the remaining PCI
slots.
The following guidelines apply to T-Class nodes.
Fibre Channel Adapters
Fibre Channel adapters are used for drive chassis and host connections.
Drive Cage Connections
For T-Class nodes, the optimal Fibre Channel adapter loading order for drive cage connections
are PCI slots 0, 2, and 4.
Host Connections
• For T-Class nodes, the optimal Fibre Channel adapter loading order for host connections is
PCI slots 5,3, 1, and then slot 4 (when available).
• When making more than one connection from a single host, you should connect to ports in
Fibre Channel adapters installed in different nodes. Optimally, these nodes should be
horizontally adjacent, such as nodes 0 and 1 or nodes 2 and 3.
Ethernet Adapters
When present, Ethernet adapters should be installed in PCI slot 4 or 3 of the highest numbered
controller node pair of each storage system.
iSCSI Adapters
When present, iSCSI adapters should be installed in PCI slots 5, 3, and 4 of the controller node.
Node Connection Matrix
See Table 32 (page 212) to determine the correct Fibre Channel adapter configuration for the
controller nodes in a system. The diagrams in the right column of the table represent the PCI slots
in each controller node. In these diagrams, an X represents a PCI slot not occupied by a Fibre
Channel adapter.
NOTE: The following diagrams may not be accurate when Ethernet adapters or iSCSI adapters
are installed.
