I would start with 8 total NICs in each server and if you can afford it, even consider 10 NICs (NIC ports). Use a setup like this: - 2 Ports in a team for host management - 2 Ports in a team for VM-to-LAN traffic - 2 Ports in a team for heartbeat/CSV/Live Migration traffic - 4 Ports non-teamed for iSCSI with 4 unique subnets If you have to limit it to 8 ports on your server, you could limit host management to just 1 port and also limit the heartbeat/CSV/Live Migration traffic to 1 port. On an extreme budget, you could use 1 port for host management and VM-to-LAN traffic and then 1 port for heartbeat, but I'd reduce iSCSI to just 2 ports before doing this option to get to just 6 ports. When teaming, it's best to use 2 or more ports from the same NIC vendor (Intel or Broadcom), even if opting for Windows native teaming.
I'm trying to connect a SAN: I'm aware of the technical guides, deployment guides, etc. But all I can find is a addressing schema for the disk arrays. I've been searching these forums for simular questions, but mostly they are about configuring the controllers and iscsi ports, but not about the servers. I've connected the disk array controllers with the management ports per array (1 per controller) to the LAN-switch (management vlan). The eight iscsi ports per array (4 per controller) are connected to the dedicated SAN-switches. Half the ports to the first SAN-switch. The other ports to the second SAN-switch. But I can't get the idea about how to connect the Hyper-V hosts. The Hyper-V hosts are at this time 3 exact similar PER710 servers. There will be 2 more in a few months. Therefor I did choose for a cabling schema with switches, and not directly conntected to the disk arrays. My Hyper-V hosts all have two dedicated NICs (not teamed, jumbo frames, multipath) for ISCSI traffic. What will be the perfect addressing scheme for this setup? I've read about different subnets for the disk array iscsi ports. Lets call them subnet A, B, C, D. And there is an other subnet for the management ports, connected to the management vlan on my LAN-switches. Lets call this subnet E. In which subnet do I have to put the iscsi ports of my Hyper-V hosts?
