Access Gateway allows a switch to operate in a special agmode that allows simplified connectivity between large numbers of servers and the SAN. Access Gateway leverages NPIV (N_port ID virtualization) to hide the complexity of the servers (both physical and virtual) attached to it while allowing easy SAN connectivity. The edge fabric switch provides all the fabric services while Access Gateway connects to the edge switch by what appears as a Host Bus Adapter (HBA) connection. This architecture allows the deployment of many additional servers without requiring a domain and the associated fabric rebuild traffic that is prevalent when switches are powered on, or added, or removed from a fabric. Refer to the Brocade Access Gateway Administrator's Guide available on http://www.hp.com/go/san for more information. Access Gateway support in McData fabrics In addition to being supported in Brocade fabrics, Access Gateway is supported for connectivity to McDATA fabrics running E/OS 09.00.00. Dynamic Ports on Demand (DPOD) IMPORTANT: DPOD is supported only in the following HP product: • Brocade 4Gb SAN Switch for HP c-Class BladeSystem (Brocade 4024) Please check http://www.hp.com for the latest updates. DPOD is an optional feature on the embedded switches listed above. DPOD takes the expansion capability of fixed Ports on Demand (PODs) and adds the flexibility of connecting to any available port as long as a valid license is available. Previously, POD allowed only specific ports to be utilized. With DPOD, any physically available port can be made active as long as a valid license is available. This allows customers the flexibility of automatically changing port assignments where previously the port assignments were fixed and inflexible. Reliability, Availability, Serviceability (RAS) • Audit logging provides logs per user-generated events, such as security violation, zoning, firmware download, and configuration changes. • Configuration management enhancements improve switch availability by allowing Fabric Watch and SNMP parameter changes to be non-disruptive. • Firmware upgrade enhancements provide clearer error messages and remove the need to enter release.plist in the command line. • Daemon restart/monitoring restarts management daemons automatically when they fail without switch reboot: • Simple Network Management Protocol Daemon (SNMPD) • Web Server Daemon (Webd) • Common Access Layer Daemon (CALD) • Remote Procedure Call Daemon (RPCD) • Event Monitor Daemon (EVMD) • Asynchronous Response Router Daemon (ARRD) sends management data to hosts when the switch is accessed via FA API or SMi-S. • Track Changes Daemon (Trackd) • Port Mirroring captures traffic between two devices for non-disruptive traffic analysis (available on the SAN Switch 4/32, 4/64 SAN Switch, 4/256 SAN Director, and 400 MP Router).

as long as a valid license is available. Previously, POD allowed only speci

DPOD, any physically available port can be made active as long as a valid license is available. This

Reliability, Availability, Serviceability (RAS)
•
Audit logging
provides logs per user-generated events, such as security violation, zoning,
fi
rmware
download, and con
fi
guration changes.
•
Con
fi
guration management enhancements
improve switch availability by allowing Fabric Watch
and SNMP parameter changes to be non-disruptive.
•
Firmware upgrade enhancements
provide clearer error messages and remove the need to enter
release.plist
in the command line.
•
Daemon restart/monitoring
restarts management daemons automatically when they fail without
switch reboot:
•
Simple Network Management Protocol Daemon (SNMPD)
•
Web Server Daemon (Webd)
•
Common Access Layer Daemon (CALD)
•
Remote Procedure Call Daemon (RPCD)
•
Event Monitor Daemon (EVMD)
•
Asynchronous Response Router Daemon (ARRD) sends management data to hosts when
the switch is accessed via FA API or SMi-S.
•
Track Changes Daemon (Trackd)
•
Port Mirroring captures traf
fi
c between two devices for non-disruptive traf
fi
c analysis (available on
the SAN Switch 4/32, 4/64 SAN Switch, 4/256 SAN Director, and 400 MP Router).
