1.5.5 IBM Flex System FC5022 16 Gb SAN Scalable Switch
The IBM Flex System FC5022 16 Gb SAN Scalable Switch is a high-density, 48-port 16 Gbps
Fibre Channel switch that is used in the Enterprise Chassis. The switch provides 28 internal
ports to compute nodes by way of the midplane, and 20 external SFP+ ports. These SAN
switch modules deliver an embedded option for IBM Flex System users deploying storage
area networks in their enterprise. They offer end-to-end 16 Gb and 8 Gb connectivity.
The N_Port Virtualization mode streamlines the infrastructure by reducing the number of
domains to manage while enabling the ability to add or move servers without impact to the
SAN. Monitoring is simplified by an integrated management appliance, or clients using
end-to-end Brocade SAN can leverage the Brocade management tools.
Two versions are available, a 12-port switch module and a 24-port switch with the Enterprise
Switch Bundle (ESB) software. The port count can be applied to internal or external ports
using a a feature called Dynamic Ports on Demand (DPOD).
With DPOD, ports are licensed as they come online. With the FC5022 16Gb SAN Scalable
Switch, the first 12 ports reporting (on a first-come, first-served basis) on boot-up are
assigned licenses. These 12 ports can be any combination of external or internal Fibre
Channel (FC) ports. After all licenses have been assigned, you can manually move those
licenses from one port to another. As it is dynamic, no defined ports are reserved except ports
0 and 29. The FC5022 16Gb ESB Switch has the same behavior, the only difference is the
number of ports.

1.5.6 IBM Flex System FC3171 8 Gb SAN Switch
The IBM Flex System FC3171 8 Gb SAN Switch is a full-fabric Fibre Channel switch module
that can be converted to a pass-thru module when configured in transparent mode. It can be
done using the switch GUI or CLI and then the Module can be converted back to a full
function SAN switch at some future date. The switch requires a reset when turning
transparent mode on or off.
The I/O module has 14 internal ports and 6 external ports. All ports are licensed on the switch
as there are no port licensing requirements.
On this switch, when in Full Fabric mode, access to all of the Fibre Channel Security features
is provided. Security includes additional services available, such as Secure Socket Layer
(SSL) and Secure Shell (SSH). In addition, RADIUS servers can be used for device and user
authentication. After SSL/SSH is enabled, then the Security features are available to be
configured. This allows the SAN administrator to configure which devices are allowed to login
to the Full Fabric Switch module, by creating security sets with security groups. They are
configured on a per switch basis. The security features are not available when in pass-thru
mode.
