Hi Guys,
I've got a best practice question.
I have an ISCSI unit with two controllers. Each controller has two ports. The configuration is as follows:
Controller A:
P1: 192.168.7.1/24
P2: 192.168.8.1/24
Controller B:
P1: 192.168.7.2/24
P2: 192.168.8.2/24
Each controller is connected to two switches. P1 -> SW1, P2 -> SW2.
Each server has two NICs dedicated for ISCSI traffic. The question is, how many VMKs should I be running per physical NIC? One? Or two?
I could set it up either way, but I'm not sure which way it should be done. Currently all the hosts have one VMK per NIC. My argument is despite how many VMKs I have, the throughput is still limited to 1GB/s per server port(the ISCSI unit is 10GB/s per port).
Option 1:
Server A:
- NIC3
- VMK1: 192.168.7.20/24
- VMK2: 192.168.8.20/24
- NIC4:
- VMK3: 192.168.7.21/24
- VMK4: 192.168.8.21/24
Option 2:
Server A:
- NIC3:
- VMK1: 192.168.7.20/24
- NIC4:
- VMK2: 192.168.8.20/24
Is it unwise to have a physical NIC with two VMKs? I'm just not sure if two VMKs per physical NIC is "right" as it might result in performance loss?
TIA!
