Flag for United Kingdom of Great Britain and Northern Ireland asked on

MPIO or Network Teaming

In this scenario:

2 or 3 ESXi Servers
Single Managed Switch
Single SAN

Imagine we have 3 NICs for the DATA network and 3 NICS for the SAN network for each host.

What would be consideration be for Teaming VS MPIO?

The reasoning for MPIO that was presented to me was this:

Teaming can send on all ports but only receive on one - MPIO theoretically can send and receive on each NIC full duplex as each has its own IP address.

Now I'm not convinced that is all there is to it...

What are the Pros and Cons to each, and how are they applied?

Thoughts?

can you add hardware to your san if so go 10gbe copper as thats going to be a major player in the next few years especially for virtualization and you need a spare slot in your server but that will make your san the best it can be as the 10gbe hba's are about £400 at the moment as its usually an £300 option on new servers and its starting to become a viable option especially for storage

why you cannot use mpio or teeming for storage thats why I am saying go 10gbe

Lets pretend 10GBe is out of the question.

Sorry your link seems to be specific for Hyper-V, with VMWare I know Teaming does work as I have it like that right now.

A colleague is setting up another similar install and we were just debating MPIO vs Teaming.

kevinhsieh

MPIO is only available for VMware Enterprise or Enterprise Plus licenses as I understand it, so that might eliminate it from consideration right there.

The reality is that my SAN has 6 network connections, 6 Hyper-V hosts and maybe 60+ VMs, and I rarely see any of the gig ports above 10%, so this is probably more of a theoretical vs a practical discussion.

but wont the san need mpio as well

as its a moot point if it doesn't

You have to check with your SAN vendor to see if it supports MPIO. I know EqualLogic does out of the box.

Ok, so lets say theoretically that everything supports MPIO (licenses, hardware) and that traffic is substantial enough to see a difference (if there is one).

thats why I think 10gb is going to be massive with vmware as it alows a fast san with no teaming if you dont want it so the vmware world is taking stcok of what can be done with 10gbe as thats the furtue of all current servers has an option for a 10gbe nic and the price has dropped so much in the last few years even the san world will be starting to use them as well

I know how awesome 10gbe is...but can we please forget about that bit?

Its not part of the equation right now!
