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

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

  1. Introduction to Failover Clustering
  2. Cluster Deployment and Upgrades
  3. Cluster Networking
  4. Cluster Storage & Scale-Out File Server
  5. Hyper-V Clustering
  6. Multi-Site Clustering & Scale-Out File Server
  7. Advanced Cluster Administration & Troubleshooting
  8. Managing Clusters with System Center 2012 R2

Failover Clustermanager Cluster Network – Network Interface only shows IPv6 Localloop

The todays post is inspired by some questions I often see when look around in forum for microsoft clustering.

Many people who are using Microsoft Failover Cluster Manager the first time, encounter that they see an unnamed cluster network with an IPv6 Loopback adresse.

Often they see it as a failure in Cluster manager. That is not the case. Mostly the reason is very simple. You have a Networkcard in your system which has no IPv4 or any IP at all.

22-05-_2015_19-45-36

Now you need to find why the reason why you don’t got an IP. The most common reasons are:

– you have no DHCP Server in that network and no static IP configured
– you get no IP from the DHCP server because of wrong VLAN or Port is not cabled correctly

So the easiest and most common issue is, that you forgot to set the IP. So set the IP for that networkcard.

After you set the IP your Failover Cluster Manager sees the new IP and everything looks fine 🙂
