Hyper-V|W2k12R2|4x10GB

Hyper-V Cluster Network configuration with following parameters:

The following configuration leverages 4x 10GB 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
– High Bandwidth for VM- Good Bandwidth for Storage
– Software Defined Network can be fully controlled from the Hypervisor
– Full fault redundant
– 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
– Combination between Hardware Defined and Software Defined Network is sometimes hardly to understand

 Switches

10GBE SW01 10 GBit/s physical stacked or independed
10GBE SW02 10 GBit/s physical stacked or independed
SoftSW01 10 GBit/s Software defined / converged
