Hi everybody,

last week something awesome happend to me. I was ask by the European Commission (the Executive of the European Union) to join their expert panel regarding Software Defined Network and Network Function Virtualisation. Therefor I will travel to brussel for some workshops and take part in some online surveys. I don’t know how I deserved it but I really love to take chance to meet other experts and discuss with them.

If you want to read more about that project, please click on the picture.

Hyper-V Cluster Network configuration with following parameters:

The following configuration leverages 8x 1GB Ethernet NICs and LOM (LAN on Motherboard) and 2x 10GB Ethernet NICs. The storage can be connected via iSCSI with MPIO or SMB 3.x.x without RDMA. The configurations uses physical configuration and software defined / converged network for Hyper-V.

 Pro’s and Con’s of that solution

 Pro Con
– Good Bandwidth for VM
– Good Bandwidth for Storage
– Separated NICs for Livemigration, Cluster and Management
– Full fault redundant
– Can be used in switch independent or LACP (with stacked switches) teaming mode
– Only one Hardware Technology is used		 – Network becomes limited by a large number of VMs
– Combination between Hardware Defined and Software Defined Network is sometimes hardly to understand

Done use that configuration in production! It’s only for lab use!

This configuration is very similar to the 4x 10Gb Ethernet config but not useable for production.

Hyper-V Cluster Network configuration with following parameters:

The following configuration leverages 3x 1GB Ethernet NICs and LOM (LAN on Motherboard). The storage can be connected via iSCSI with MPIO or SMB 3.x.x without RDMA. The configurations uses physical configuration and software defined / converged network for Hyper-V.

 Pro’s and Con’s of that solution

 Pro Con
– Easy to build and good for lab use
– enougth bandwidth for test workloads
– fully converged		 – limited bandwidth
– no production use
– cheap to build

 Pro’s and Con’s of that solution

 Pro Con
– High Bandwidth for VM- Good Bandwidth for Storage
– Software Defined Network can be fully controlled from the Hypervisor

– Can be used in switch independent or LACP (with stacked switches) teaming mode
– Only one Hardware Technology is used		 – Becomes limited by a large number of VMs
– Network admins won’t like it

Hyper-V Cluster Network configuration with following parameters:

The following configuration leverages 4x 1GB Ethernet, 2x 10GB Ethernet NICs and LOM (LAN on Motherboard) and 2x Fibre channel connections. The storage can be connected via Fibre Channel with MPIO. The configurations uses physical configuration and software defined / converged network for Hyper-V.

 Pro’s and Con’s of that solution

 Pro Con
– High Bandwidth for VM- Good Bandwidth for Storage
– Separated Management and Heartbeat Interface
– Full fault redundant
– Can be used in switch independent or LACP (with stacked switches) teaming mode
– Fibrechannel ist most common SAN technology		 – Limited Bandwidth for Livemigration
– a lot of NICs and Switches needed
– a lot of technologies involved
– expensiv
