vsphere virtual switch

I have asked a similar question before, although came to this solution.  Right now I have several zone I need to use, would this virtual switch configuration make sense or let me know any other variations that may work better:

6 nic's on the physical servers

zones
Management, vMotion - 1 port
iSCSI -2 ports
Trust - 2 ports
DMZ - 1 port

Also, does iSCSi need to be on a vm kernel port?

Also, can I do without FT?  I was also thinking of doing the DMZ at a later date.  Let me know any improvements on this setup.

Hello,

You may want to change the settings as such:

zones
Management - 1 port
vMotion - 1 port [You can then have a redundant management network over this]
iSCSI -2 ports
Trust - 1 ports
DMZ - 1 port

I split vMotion out as it's kind of important to have a dedicated network for that, also depending on version 1GB vMotion port limits you to 4 concurrent vMotion migrations and to achive 8 you need to go 10GB. I have heard you can get 8 via 2 independent 1GB vmkernel ports sounds logical.

And yes vMotion needs a vmkernel port, FT is overrated and intensive on resource.

iSCSI does need to use a VMKernel Portgroup, because this is a special portgroup which carries the traffic.

this looks fine, however, you have no resilience or teaming for your management network?

what network do your VMs use?

okay, thanks; the vm's use trust and dmz networks

You do not have any resilience/teaming for your Trust of DMZ networks.

Two NICs is better than One, single point of failure!

you could create a vSwitch with Trust, DMZ and Management Network, trunk and VLAN?

does your Management Network use the same network as Trust?

no different networks than trust; i prefer not to change, i guess i could try and get 2 more nic's  per server even and do without the dmz for the interim

It's up to your network design, if you want to add additional nics for resilience, teaming, throughput and availability, whether active/active, or active/standby.

We always recommend at least two nics per service, but depends on your network arrangement, if you only have a single physical switch it all connects to, you need to look at entire network design.

this is where VLANs and Trunks have advantages, less nics, less cables, but slightly more configuration required.
