Build microsoft cluster vmware

Five node clusters are possible only two nodes in vSphere 5. You must use at least VM hardware version 7. Shared disks need to be the thick provision eager zeroed. Only fibre channel SANs are supported. Update: in vSphere 5. Third-party multipathing using round robin may be supported but check with your storage vendor. Note: In vSphere 5. Memory overcommitment is not recommended, overcommitment can be disruptive to the clustering mechanisms optionally set VM, memory reservations.

Pausing or resuming the VM state is not supported. Use Cases: Invariably it depends on the application, the application needs to be cluster-aware, not all applications support Microsoft Cluster Services. Web, DHCP, file and print services Implementation Options: Before we look at the various implementation options it may be worth covering some of the basic requirements of an MSCS cluster, a typical clustering setup includes the following: Drives that are shared between clustered nodes, this is a shared drive which is accessible to all nodes in the cluster.

A private heartbeat network that the nodes can use for node-to-node communication. A public network so the virtual machines can communicate with the network. The shared disks or quorum either local or remote is shared between the virtual machines. CIB can be used in test or development scenarios, this solution provides no protection in the event of hardware failure. This protects against both software and hardware failures. Physical RDMs are the recommended disk choice.

This mode can be used in order to migrate from a physical two node deployment to a virtualised environment. Physical RDMs are the recommended disk option here. SCSI bus-sharing setting: virtual sharing policy or physical sharing policy or none. Virtual: Use this value for cluster in box deployments CIB. ESXi 5. If you want to learn more about it, this one is a really good starting page. There are some configurations and steps that need to be taken to make it run inside virtual machines.

The final result is going to be a 4 nodes cluster, as this is the minimum amount of nodes that is required. This is paramount to guarantee the correct identification of the disks by the Storage Spaces wizards.

So, be careful about the storage consumption as these disks are going to be completely inflated from the beginning.

On a virtual machine, this can be done by adding:. Windows also properly identifies the other disks. Without the Physical Bus sharing in fact, there will be for each disk this error during the cluster validation:.

In fact, without setting this option, during the validation of a new node in the cluster, you will see this error in the Storage Spaces Direct configuration:. This can also be appreciated using Powershell. With regular disks and no BUS Sharing, this is the output:. Windows TP5 is installed on all the four nodes, and they are all joined to my domain. There are two networks on each node, and the final configuration is like this:. Also, you will see later there are some steps that need specific options that may not be available via the graphical interface.

I will not go too deep into the subject here since most of the settings and configurations were covered in the previous section, the CAB section , so if you need extra information, please read that section.

The most important thing in making this work is to map the same LUNs to the physical and virtual machines. During the Windows Failover Cluster validation configuration wizard, everything should be good and green. In the end, I will leave it up to you to choose which type of Windows clusters you want to build on your VMware infrastructure, but take advantage of this for your sensitive applications and services so you have at little as possible of downtime.

Of course this is just anon internet guy advice, you always choose yourself what to fu…fun with in production. Thanks a lot for creating this blog with a lot of good information. Would you mind to make two changes to the content: 1. Add a mention that starting with vSphere 7. This is an interesting article. Would it be possible to adapt this type of clustering for printing?

Hi, Sure, it works. The cluster service does not know if it is a virtual environment or not. Would any of the steps change if my nodes are Server ? You began with and OS. Also, a previous comment mentioned writing about adding the disks within Windows.

Did you do that? Would be helpful as you said. Thank you again! Hi, It will work great for Server , as for the other article I did not get a chance yet, but it on my table. Given that WSFC anyway cares to make the shared disk usable on one node only?

You can give it a try with some pilot users and see how it works, but on some heavy clusters I will not try this. Hi, Thanks for the idea. I will start creating an article about this, just make sure you are subscribed to my newsletter to be notified when is published.

Are you able to provide the information you found from VMware regarding the compliance of this in a production environment? At least the official vmware documentation does not say that it has to be established. Hi John, I followed the VMware docs just to be sure and it is supported. I also tested it and it works great.

Let me know if you have any other doubts and I will try to explain them. Which doc? Hi Richard, Link works, try again and clear your browser cache.
