SCVMM2012 to manage all Hyper-V 2012 ?

I've been testing several scenarios.  On a Windows 2012 environment (cluster Hyper-v 2012) I started to test SCVMM 2012.  I set up the fabric: logical switch, logical network...  

SCVMM takes over the Hyper-V servers.

In the event that something goes wrong in SCVMM it can be a problem as far as I can see.   If the virtual switch is deleted in SCVMM, it's gone everywhere else.  Of course nobody will ever delete a virtual switch like that.  

But I'm concern.  How dependent are we on SCVMM when almost all configuration is done from SCVMM?

SCVMM 2012 SP1 handles all the Network Virtualisation, (which is a new feature of SP1) if it fails, you will have issues with networking, hence why Microsoft encourages you to have resilient SCVMM 2012s.

Hi Andrew

I can see that.

So I need resilient SCVMMs and hardware Gateways if I want to create an hybrid cloud.   More layers again.  I think I'll stick with the old model.  Unless we need to provide cloud service to clients I don't think handling all the networking from SCVMM is a good bet.

Hyper-V 2012 cluster is very stable.  Configuring all VLANs for VMs within the Hyper-V Virtual Network Switch is quite easy (powershell) SVMM is useful to create templates and for live migration.  As we don't need to create a lot a VMs everyday

But that aside overall it's easier - or at least safer -  to manage the networking in Hyper-V 2012.

Unless you can give me a good reason not to, I think it's still better to keep the networking out of SCVMM for small and medium business like us (about 150 to 250 users)

Otherwise SCVMM SP1 handling all the networking virtualisation is a feature to use only in large organizations or to provide cloud services.  

Thanks again

I'm still puzzling over the benefits of SCVMM 2012 SP1, which has become overly complex, at the networking layer.

Unless you need the features of SCVMM 2012 SP1, or our considering a Mult-Tenant Cloud Solution......

So I am.  

I think we're not alone to think that SCVMM SP1 has brought new layers of conmplexity in the game.  

Microsoft was promoting SCVMM SP1 as the most easier way to get into the cloud ever.  But the more I'm reading on technet and books, the more it gets as you said overly complex.  

When I learned that I had to add gateways !  Hybrid cloud was no longer a solution we were after.  

I have my answer thanks to you.

What we do like, but I'm not sure if it's applicable to everyone, it very much depends on your Network Infrastructure and Management, and who is responsible for Network Configurations.

Microsoft is keen to let you configure your VLANs for your DATACENTER Networking Backbone ONLY, e.g. Storage, Live Migration Clustering, Management Network....

and then use Network Virtualisation "inside SCVMM SP1" to handle Client Networks, this is a good idea, where Clients, DO NOT HAVE access, or Network Engineers on hand to configure VLANs, also you do not need any Layer 3 switches, that handle VLANs to do this.

So, in conclusion, for the Large DATACENTER, CLOUD Builder, Multi Company, Tenated networks, I can understand the concept.

But it would seem, Microsoft are trying to play catchup with VMware vSphere Enterprise Plus and Distributed Virtual Switches, which allows you to present the same configuration across all hosts within your FARM, which is a good idea for Hyper-V Hosts!

and, when you compare VMware vSphere versus Hyper-V, it looks good, like for like, tickbox for tickbox, and you get Network Virtualisation, Logical Switches for FREE *unlike VMware.

BUT, it's a real shame, for the smaller Business, not interested in Virtual Networks (not VLANs), because they have easy access to do VLAN config, or do not use VLANs, you cannot enable,

Basic Network Mode or Advanced Network Mode.
