McDATA 3000 manual Fibre Channel Switches

Network Design

•The UltraNet Edge 3000 does not listen to routing broadcasts. One default gateway can be configured along with multiple host and network specific static routes. Generally the default gateway is defined for the Ethernet maintenance interface and the other static routes are used for the WAN.

•The end-to-end network must have less than 1% packet loss.

•The UltraNet Edge 3000 has SNMP support. SNMP access can be configured to limit Get or Set requests on a host specific basis. Up to six Trap destinations can be defined (see Appendix F, Configure SNMP, for more information).

•The end-to-end network latency must be less than or equal to 200ms round-trip latency with less than 10% jitter.

Fibre Channel Switches

NOTE: The UltraNet Edge 3000 contains an internal Fibre Channel switch (FCSW) application and when configured for F_port, an external Fibre Channel switch is not necessary unless more than two Fibre Channel ports are needed.

•McDATA supports F_port using the McDATA internal Fibre Channel Switch (FCSW) application over an ATM WAN interface.

•McDATA supports E_port extension and Device Extension (FC/SCSI Tape Pipelining) using Brocade and McData Fibre Channel switches over an ATM WAN interface.

•The FCSW application allows remotely connected N_ports to login and see other N_ports via this application using standards compliant services.

•A LC to SC fiber cable is needed to connect the UltraNet Edge 3000 to a Brocade 2000 Series Switch.

•A LC to LC fiber cable is needed to connect the UltraNet Edge 3000 to a Brocade 3000 Series Switch.

•The Brocade switches need specific flash parameters specified (see the chapter on “Brocade Switch Requirements” in the UltraNet Edge Storage Router - 3000 Series Release Notes).

•The FCBB card auto-senses the attached port speed and adjusts accordingly.
