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

virtua lization) 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 m a ny 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.

Access Gate

way support in McData fabrics

In addition

to being supported in Brocad e fabrics, Access Gateway is suppor ted for connectivity to

McDATA fabr

ics running E/OS 09.00.00.

Dynamic Ports on Demand (DPOD)

IMPORTANT:

DPOD is supported only in the following H P product:

• Brocade 4 Gb SAN Switch for HP c-Class BladeSystem (Brocade 4024)

Please check h

ttp://www.hp.com for the latest updates.

DPOD is an optional feature on the embedded switches listed above. DPOD takes the expansion

capability of ﬁ xed 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 ava ilable port can be made a ctive 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 p er user-genera ted events, such as security violation, zoning, ﬁrmware

download, and conﬁguration changes.

• Conﬁguration management enhancem ents 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 Pro ce dure Call Da em on (RPCD)

• Event Monitor Daemon (EVMD)

• Asynchronous Response Router Daemon (ARRD) sends management data to hosts when

the switch is accessed via FA A PI 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).
