    Over the past week I have been putting together an overview/study guide for ESXi networking as I'm preparing for my VCP 5 exam.

    I have tried to cover the points that I find appropriate and use language that means something to me!

    Hopefully it might help a few people out.

    I'm surprised no one has commented on this. I thought there were some interesting topics on your blog and gave them a read. I'll probably read anything vm at the moment tho :D

    A couple of comments on part 1, for clarity:

    - you can't trunk a vSwitch with another vSwitch
    - the default port group name has a space in it - it's "VM Network"
    - port group name consistency across hosts is required for VM migration and failover

    - - - Updated - - -

    And comments on part 2:

    - VMkernel ports are also used for HA heartbeats
    - multiple VMkernel ports enables VMkernel networking across multiple IP subnets and VLANs
    - technically, VMkernel ports do not require an uplink to work - uplinks are there to connect the vSwitch to an equivalent uplink port on a physical switch

    And part 3:

    - what do you mean by "connections" in the first sentence? The load balancing policy determines what happens
    - ESXi can only load balance on traffic that leaves the host through an uplink, but the physical network can still load balance on what comes into a host
    - you are not guaranteed an even balance of VMs to uplink with the default load balancing policy
    - a VM NIC can be assigned to a new port ID if you alter the VM NIC is connected to an alternate port group then back to the original port group
    - you don't have to have all the uplinks connected to the same physical switch to use the IP hash policy if your switches are stackable - the key requirement is the physical switch ports must be aggregated using 802.3ad, or Etherchannel as Cisco would call it
    - the notify switches option causes the transmission of a RARP when those events occur
    - your definition of the security options isn't clear
    - you didn't discuss the fail back policy

    I shouldn't post so late at night, I forgot to say that I actually like the articles - easy to read/consume :-)
