IBM Flex System V7000 Storage Node Introduction and Implementation Guide
– Fabric ports (F_Port), these ports are found in Fibre Channel switched fabrics. They
are not the source or destination of IU’s, but instead function only as a “middle-man” to
relay the IUs from the sender to the receiver. F_Ports can only be attached to N_Ports.

– Expansion ports (E_Port), these ports are found in Fibre Channel switched fabrics and
are used to interconnect the individual switch or routing elements. They are not the
source or destination of IUs, but instead function like the F_Ports to relay the IUs from
one switch or routing elements to another. E_Ports can only attach to other E_Ports.

The E-Port is not strictly used within the chassis but as shown in the example in Figure 11-19
on page 459 it may be used to connect to external SAN fabric switches. Thus allowing
integration of the SAN fabric at switching level for IBM Flex System V7000 Storage Node to
access and manage external storage controllers.

11.5.3 Zoning a Compute Node for Storage Allocation
Connectivity over Fibre Channel between the compute nodes and IBM Flex System V7000
Storage Node is achieved through the adapter in the computer node and Fibre Channel
switches in the IBM Flex System Enterprise Chassis I/O Module slots. In this section we will
look at the connectivity between the FC switches in IBM Flex System Enterprise Chassis I/O
Module slots 3 and 4 and configure zones to an IBM Flex System x240 Compute Node. The
FC switches used are the IBM Flex System FC3171 8Gb SAN Switch models.

Although the SAN connecting components are within the IBM Flex System Enterprise
Chassis with both FC switches in I/O Module slots, the result is a basic and small pair of SAN
fabrics. Each have the capability of connecting to external SAN fabrics as they have external
ports (label 2 in Figure 11-21 on page 461). Also, within the chassis there will be a
requirement to segregate FC initiators from each other and maintain separation of compute
nodes. For this reason SAN zoning rules must be applied and the IBM Flex System FC3171
8Gb SAN Switch in each slot must be zoned.

In the example below we show how to connect to, log in and start the zoning configuration
process on one FC3171 8Gb SAN Switch. The procedure has to be repeated on the second
switch in the IBM Flex System Enterprise Chassis. To access the switch we used browser
option for ease of use, although there is CLI which can be accessed via a SSH session. The
browser we used below was Firefox which used Java to create the configuration windows.

The switches IP address can be ascertained from the CMM as shown in 3.2.4, “Accessing I/O
Modules using CMM” on page 94.

From your chosen browser enter the IP address of the switch:
https://xxx.xxx.xxx.xxx
Figure 11-20 on page 461 shows the login prompt from the Java window, the default user is
‘USERID’ with the password ‘PASSW0RD’ (the ‘0’ in the password is a ‘zero’).
