Dedicated CSV Network and Single iSCSI 10 GB Link?


i need information on including csv dedicated network or if on kill?  designing 2012 r2 environment 4 blades host.  on end have 2 modules redundancies give 8 usable nics.  routed through 2 redundant switches.  10 gb switch, etc..... 

  • management network
  • vm network (client data)
  • csv network
  • live migration network
  • cluster heartbeat network
  • iscsi (san)
  • backup network

question hyper-v peers this, understand reasoning behind csv network.  allowing data move between 4 host if 1 of san networks goes down.  however, needed?  if use plan use live migration network csv network. 

so, think?  should keep csv network , combine live migration network , make sure network card set lowest priority? 

1 more question.  our current design gives 10 gb iscsi connection.  again on plane redundant , connected redundant switches.  problem see have since host sees 1 network warnings don't have redundancy?  should need worry mpio , ignore warnings?

this looks good. published best practices guide recommends min. 5 networks, you're good. 

about iscsi , mpio, need mpio if there's more 1 path between initiator (your server using iscsi lun) , target (the san that's unmasking lun). so, if have 1 iscsi nic on hyper-v host (initiator) , 1 iscsi nic on san, there's no need mpio, since there's 1 path. if have 2 iscsi nics on host, , 2 iscsi nics on san, have 4 paths between particular initiator , target. depending on san vendor may have manually spell out 4 path in mpio config (simply pointing out ipv4 address of each of 4 nics. not nic team or port channel iscsi nics. installing mpio require reboot. default mpio algorithm round robin, can changed, need so.
