    Oracle VM Server for SPARC - network multipathing architecture question

    908246
      This is a general architecture question about how to best setup network multipathing

      I am reading the "Oracle VM Server for SPARC 2.2 Administration Guide" but I can't find what I am looking for.

      From reading the document is appears it is possible to:
      (a) Configure IPMP in the Service Domain (pg. 155)
      - This protects against link level failure but won't protect against the failure of an entire Service LDOM?
      (b) Configure IPMP in the Guest Domain (pg. 154)
      - This will protect against Service LDOM failure but moves the complexity to the Guest Domain
      - This means the there are two (2) VNICs in the guest though?

      In AIX, "Shared Ethernet Adapter (SEA) Failover" it presents a single NIC to the guest but can tolerate failure of a single VIOS (~Service LDOM) as well as link level failure in each VIO Server.
      https://www.ibm.com/developerworks/mydeveloperworks/blogs/aixpert/entry/shared_ethernet_adapter_sea_failover_with_load_balancing198?lang=en

      Is there not a way to do something similar in Oracle VM Server for SPARC that provides the following:
      (1) Two (2) Service Domains
      (2) Network Redundancy within the Service Domain
      (3) Service Domain Redundancy
      (4) Simplify the Guest Domain (ie single virtual NIC) with no IPMP in the Guest


      ---

      Virtual Disk Multipathing appears to work as one would expect (at least according the the documentation, pg. 120). I don't need to setup mpxio in the guest. So I'm not sure why I would need to setup IPMP in the guest.
