How to make Nexus 5k work with HP SAN

[GREG FRISINGER]

I have a Nexus 5548 wth a 8X10GE + 8x1/2/4/8G FC Module installed.  The server guys purchased a HP SAN "

HP P2000 G3 FC 24x600GB SAS SFF"  with a HP blade chasis and they want to know if they can use the 5k to connect from the blade server via the C N A cards to the HP SAN.  From what I find on the Internet, I can't seem to get a straight answer.  I keep reading I may or may not need a MDS.

Has anyone done this ?

What would the config look like connecting to the SAN ????

sure, you will need to configure VSAN and FCOE enabled VLAN. P2000 ports will need to go into that VSAN, once you setup vfc interfaces for CNA adapters you will need to add them to the VSAN as well. At that point it's simple zoning.

CNA adapters connection will go the FCoE enabled VLAN then setup VFC interfaces ; is my understanding correct?

Greg,

does p2000 have any FCoE port

[GREG FRISINGER]

Our server guys just responed and said that is has a FCOE port.

thanks for the reply.  My problem is I'm not a SAN guy and this is our 1st attempt at adding a SAN to our 5K.  So this is all new to me.  the below is what I think I need to do.  I've been using this as an example, but he also talks about using an MDS.

Configure the ports to the MDS -  If I'm not using an MDS then how does this work
Nexus5k(config)# interface san-port-channel
Nexus5k(config-if)# channel mode active
Nexus5k(config-if)# switchport trunk mode on
Nexus5k(config-if)# switchport mode NP [E]
(Note: Pick either NP or E depending on your deployment.  NP would be for NPV mode and E would be for Fabric Switch mode (or whatever they are calling it now))
Nexus5k(config-if)# switchport trunk allowed vsan 1
Nexus5k(config-if)# switchport trunk allowed vsan add
Nexus5k(config-if)# exit
Nexus5k(config)# int , , etc…
Nexus5k(config-if)# channel-group force
(Note: We are using force, make sure that your config for port-channel is the same on both ends.  A lot of it depends on the exact setup and what features (LACP, etc..) the gear supports)
Nexus5k(config-if)# no shutdown

!!!! Map VSAN to LAN  - where do I get the VSAN number ?

Nexus5k(config)# vlan

Nexus5k(config-vlan)# fcoe vsan

!!!! VFC Interface

Nexus5k(config)# interface vfc
Nexus5k(config-if)# bind interface port-channel
Nexus5k(config-if)# no shutdown

!!!! VSAN and map to interface  -  This inteface connects to SAN

Nexus5k(config)# vsan database

Nexus5k(config-vsan-db)# vsan

Nexus5k(config-vsan-db)# vsan interface vfc

Nexus5k(config-vsan-db)# vsan interface san-port-channel

!!!! CNA Card

Nexus5k(config)# interface Ethernet

Nexus5k(config-if)# switchport mode trunk

Nexus5k(config-if)# switchport trunk allowed vlan ,,

Nexus5k(config-if)# spanning-tree port type edge trunk

Nexus5k(config-if)# speed 10000

Nexus5k(config-if)# channel-group mode active

Nexus5k(config-if)# exit

Nexus5k(config)# interface port-channel

Nexus5k(config-if)# spanning-tree port type edge trunk

Greg,

How your config went?
