Good morning all ,

This is a long one so please bear with me.

We intend to have nodes setup in a mobile platform.
Each node will comprise of , 6-8 VM’s , 2 NIC cards (teamed) , some storage . one of the VMs will be a File Share VM.

The nodes will have failover cluster setup using cluster Qorom and we would like the storage setup as spaces direct. The intention is to use the File Share VM as a witness.

The questions we have are as follows :

  1. Can cluster Qorom (failover cluster ) and pool Qorom (storage spaces) run simultanousely on the same node or do we have to go with one.
  2. if one of the node drops out of the cluster can it still support the clients attached to it with its local services.
  3. If a client moves into a closer range of another node within that cluster will it use the services from that cluster.
  4. From the shared storage ( storage spaces ) could this then be stretch clustered with a centralised static node.

I appreciate this is a weird scenario but for context imagine at a large festival several veichle with servers dotted around a large geographical location.
Both the veichles and clients have the ability to move around the area. All will be networked using sime form of wirkess tecgnology . With the clients avcessing the network via a handheld device / tablet / notebook.

Any help will be greatly appreciated

stay safe

    Hi,

    Generally, Windows failover cluster use physical steady servers as cluster nodes, if we want to use space direct, we connect physical disks to cluster nodes directly and create storage pool.

    Can cluster Qorom (failover cluster ) and pool Qorom (storage spaces) run simultanousely on the same node or do we have to go with one.

    It's recommended to put cluster quorum on a separated host instead of putting it on the clustered VM file share. If the VM is down or the VM's owner node down suddenly, we have the risk to lose the quorum.

    if one of the node drops out of the cluster can it still support the clients attached to it with its local services.

    Cluster services can failover between the cluster nodes, if one node is down, the cluster service will move the other running nodes.

    If a client moves into a closer range of another node within that cluster will it use the services from that cluster.

    If the services have two IP addresses, when the client move to the same IP address of the node, it will be. Such as mulit-subnet SQL cluster.

    From the shared storage ( storage spaces ) could this then be stretch clustered with a centralised static node.

    I'm not very clear about this question. If you want to do stretch cluster, please check the following article:

    Thanks for your time!
    Best Regards,

    Hi,

    What I was wondering cluster / pool and qorom both have different statistics on how many nodes / drives you can lose whilst still maintaining the cluster / storage space .

    You may check the following about the learn the detailed information about Fault tolerance of Storage space:

    https://learn.microsoft.com/en-us/windows-server/storage/storage-spaces/storage-spaces-fault-tolerance

    I’m addition what’s the minimum network requirements in terms of bandwidth for the cluster to function

    As far as I'm concerned, it's recommended to set at least two cluster networks, one for heartbeat packets, and another for other network.

    If you want to know more about cluster network, please refer to the following article:
