Table 14 HP 5820X CN switch fabric rules (continued)
Description
Rule
number
Up to two 5820 FCoE modules are supported in a single 5820X switch. However, when using two A5280
FCoE modules, consider the following:
6
• When two 5820 FCoE modules are connected to the same SAN, the FCoE modules attempt to load
balance the server load across the two FCoE modules as servers are added by distributing the CNA
logins between the two modules. Failover from one module to the other is supported in this configuration,
but failback is not supported.
• The current Emulex CNA firmware does not support the load balancing method used when two 5820
FCoE modules are connected to the same SAN, so the distribution of the CNA logins may not be optimal.
This issue will be corrected in a future Emulex CNA firmware release.
Connection to Brocade 8 Gb/s switches and ARB(FF)/ARB(FF) mode setting: HP recommends all 8 Gb/s
Brocade switches running FOS V6.3.1a and later be set to mode 3 using the portcfgfillword command.

For more information, see the Fabric OS Command Reference Manual supporting FOS V6.4 and the FOS
release notes.
When connecting the 5820 to multiple SANs, unique discovery and data VLANs are required for each
SAN.

Firmware, CNA, operating systems, and storage products support
For current information on supported 5820X firmware, operating systems, and options, see the
SPOCK website at http://www.hp.com/storage/spock. You must sign up for an HP Passport to
enable access.
B-series FCoE Converged Network switch
This section describes support for B-series FCoE CN switches, switch model, and FCoE fabric rules.
For more information on configuring B-series FCoE CN switches, see “FCoE switch configuration
quick-setup instructions” (page 390).
NOTE: The naming scheme for the HP 2408 Converged Network Switch, which has 24 CEE
ports and 8 Fibre Channel ports, is slightly different from the typical B-series switch naming scheme.
Table 15 (page 83) describes the B-series FCoE CN switch.

Features
Features of the 2408 FCoE Converged Network Switch are the same as the B-series 8Gb switches,
but the following features are not supported:
• Advanced Zoning (port-based and QoS)
• Extended Fabrics
• Adaptive Networking with QoS
• Virtual Fabrics
