IBM SAN256B-6, Installation, Service And User Manual

Page: 143 / 292

Following are considerations for using these blades in SAN256B-6 and SAN512B-6 directors:
v
Port and extension blades can be mixed in device slots 3, 4, 7, and 8, but CR32-4 blades must be
installed in slots 5 and 6. Up to four hot-swappable port blades can be installed in a single chassis to
provide up to 192 32 Gbps FC ports.
v It is recommended that at least two fan assemblies be installed the SAN256B-6 if FC32-64 blades are
being used.
Port blades contain the following LED indicators. For details on interpreting LED operation, refer to
“Interpreting FC32-64 port blade LEDs” on page 83.

FlexPort allows you to configure individual ports on the FC32-64 blade for Fibre Channel (FC) or Fibre
Channel over Ethernet (FCoE) connections when qualified FC or Ethernet transceivers are installed in the
ports. Configure FC (default) or Ethernet operation for a port using the
portcfgflexport command.
v FC operation allows connection of blades to fabric storage, servers, and switches. An FC transceiver
must be installed in a port to configure FC operation for that port. Supported FC transceivers include
4x32 Gbps QSFP28 and 4x16 Gbps QSFP+ transceivers.
v FCoE operation allows connection of blades to FCoE devices as part of a unified fabric. The FCoE
devices can be servers, and the FCoE devices can be connected through a FCoE Initialization Protocol
snooping bridge (FSB). An Ethernet transceiver must be installed in a port to configure FCoE operation
for that port. Supported Ethernet transceivers include 40 GbE, 4x10 GbE, and 4x25 GbE QSFP+
transceivers.
Breakout capability allows four SFP+ front ports on qualified Fibre Channel and Ethernet QSFP
transceivers to operate at multiple speeds. For example, SFP+ front ports on a FC 4x32 Gbps SWL QSFP+
transceiver each operate at 32 Gbps or four SFP+ front ports on a 40 GbE QSFP+ transceiver can each
operate at 10 GbE. By default Ethernet ports operate in non-breakout mode, so you must enable breakout
mode for ports containing Ethernet transceivers using the
portcfgbreakout --enable
command.
Reference the following resources for more information:
v For a complete list of qualified transceivers for this blade, refer to the “Supported transceivers and
cables” on page 65.
v For more details on FCoE, FlexPort, and breakout mode features and commands, refer to the Fabric OS
Administration Guide and Fabric OS Command Reference.
FC32-64 port blade numbering and trunking
The following illustration shows how ports are numbered on the blade.
Note: Numbering (0-63) on this illustration accounts for the quad ports available for 16 installed QSFP+
transceivers. The physical QSFP+ ports are numbered 0-15 from right to left.
