ESXi Layout, NIC Assignment, and Switch Config

After a lot of researching and imput from people I think I have a decent looking layout for our new virtual enviroment (see attached image for layout). I have 3 EXSi Host each containing 6 physical NICs. This configuration and the diagram below are just for a single EXSi host, all host will be configured the exact same. pNIC 0 will handle Management and pNIC 1 will handle VMotion, they will be configured on vSwitch0. pNIC 2 & 3 will be just VM Network traffic and they will be configured on vSwitch1. pNIC 4 & 5 will handle iSCSI traffic and they will be configured on vSwitch2. All pNICs are configured with a active connection and a standby connection. I have 2 physical switches that will be configured identically. They will be configured with 2 VLANs. VLAN 50 will handle iSCSI traffic and VLAN 60 will handle vMotion traffic. Here is the switch config..

Current configuration:

!

ver 07.0.01cT7e1

!

module 1 fws1g-24-port-copper-base-module

!

!

!

!

vlan 1 name DEFAULT-VLAN by port

!

vlan 50 by port

tagged ethe 0/1/1 to 0/1/12

ip-subnet 10.10.11.0 255.255.255.0 name iSCSI

  no dynamic

!

vlan 60 by port

tagged ethe 0/1/13 to 0/1/23

ip-subnet 10.10.12.0 255.255.255.0 name VMotion

  no dynamic

!

vlan 99 by port

tagged ethe 0/1/24

ip-subnet 10.16.X.X 255.255.255.0 name MGT

Any input on the switch configuration would be appreciated!

The EMC SAN unit has two seperate processors, each containg 2 NICs for a total of 4. The SAN will have a connection from each proccesors NIC to each switch (see diagram for clarification).

Alot of this has been a learning curve for me, any input on the setup would be great!

Thanks

I changed your design to how I would do this.

vSwitch0: Management and vMotion, both on different VLANs, active/standby configuration on the port groups

vSwitch1: VM Network, both vmnics active with default policy "Route based on originating port id"

vSwitch2: iSCSI: Only one vmnic must be active on each iSCSI port group, otherwise you will not be able to configure software iSCSI

I also changed the vmnic's, so the vSwitches use ports on different network adapters/asics.

So your saying under no circumstance run the VMotion traffic through the iSCSI switches, even if they are segregated?

Well, you could use the iSCSI switches for vMotion, but in this case the active/standby configuration with the Management network wouldn't make much sense, would it!?

PS: I just saw I mixed up the vmnics Smiley Wink

vSwitch0: vmnic0 + 3

vSwitch1: vmnic1 + 4

vSwitch2: vmnic2 + 5

Andra, you are right, I didn't even think of that.. it made no sense! The main reason I was going to put the VMotion traffic on the iSCSI Switches was because I don't have enough ports in my core switch right now. I'm getting new switches in a month or so but I was needing to get this setup before then. It could be changed later.
