hyper-v server and file server out of scale RRS feed

  • Question

  • Hi guys,

    I didn't work for years in Hyper-v, I was a huge fan but ... Now I want to ask you if a have 9 hosts 5 Intel and 4 AMD and a new VMM env. from scratch can I use this host to be hyper-v servers to host VMs and same time file server scale out.

    Because I have those different  cpu types is better to have a cluster for each cpu type or a large cluster but no live migration and dynamic resource allocation, etc. If I enable cpu compatibility mode for VM's do I have any performance deteriorations or functions/features not available.

    For file server cluster make sense to use hardware raid or is better just to expose all the drives to failover cluster file server. If I have ssd and sas drives what is the best usage, on golden tier storage all flash and one silver sas raid 10, bronze raid 5 or is any other better solution to use them like vSAN with cache on flash.

    Thanks a lot for any advices.

    P.S. cant wait to have finally a robust VMM environment is boring only VMware, VMware, VMware :)

  • Hi Sir,

    >>do I have any performance deteriorations or functions/features not available.

    I will affect virtual machine performance .

    It is difficult to quantify the overall performance effects of processor compatibility mode. The performance loss is primarily dependent on the workload running in the virtual machine. Some workloads will be completely unaffected, while others will show a noticeable difference. Software that heavily relies on hardware optimizations (such as encryption, compression, or intensive floating-point calculations) will be impacted the most.

    The following example describes how AES encryption is affected by using processor compatibility mode, and there are many more.

    I want to know what is the type of storage .

    My suggestion :

    If it is JBOD , you may consider the later , just to expost all the drives to cluster nodes .

    If it is a SAN , you may consider building a normal cluster (creating hyper-v cluster directly or SOFS ).

    If neither of them , Please check this article regarding tier:
