SAN Zoning in Power dual fabric, dual VIOS, NPIV and SVC or V7000 environments

Good presentation from Bill Wiegand (thanks !)

This presentation covers SAN zoning in a dual fabric, dual VIOS Power, NPIV and SVC or V7000 environment to achieve 4 paths per LUN and to ensure zoning such that an application can continue to run in a dual failure scenario (failure of two of a VIOS, SAN fabric and SVC/V7000 node). It examines all possible 4 path configurations and shows those that meet these objectives.

  1. Looked really interesting, too bad the presentation is in .pptx :s
    What’s wrong with .pdf?

    I know this is kinda old post but I have a doubt….
    right now we have 2 brocade 300 switch (24 ports) and a v7000.
    We need to add some more servers….. so we want to know
    1. if 4 switch is a supported configuration for v7000?
    2. if so how must be connected? from Caniter 1 each port to each brocade 300? 4 = 4
    3. does the switch need to be stacked in pairs? or they can work independently?

    sorry to bother you but I don’t any documentation regarding 4 fabrics for a v7000

  3. Hi

    You can have more then 2 FC switches in front of the V7000. Here you should find the information you need ->

    Please let me know if you need further advise.

    Thanks !

      thanks a lot pretty helpful now I gotta understand the connectivity for all these 4 switches


  4. Hi, nice post.
    To complete your post, find here what happens when some of these components of SAN zoning fail.
