Can DHCP sever clustering in this way?

Question

1. Assume DHCP Servers using general purpose clustering with file share witness, DHCP servers are in Hyper V

at the same Can Hyper V also use scale out clustering ?

2. Assume SQL Servers using scale out clustering with file share witness, SQL servers are in Hyper V

at the same Can Hyper V also use scale out clustering ? outside and inside both use scale out clustering?

3. besides above doing , can veeam backup do the same way as SQL server using outside and inside both use scale out clustering
4. outside and inside both use clustering in above two situations, if I put Hyper V in VMware using VMotion and Diaster Recovery manager, is there any advantage using three layers , Guest, Host, VSphere ? any concern about this ?
5. standard version has 2 VM license, is this a clue to imply nowadays hardware can only VMotion Hyper V with 2 VM in limited time? is 2 VM the optimal number of VM in Hyper V for VSphere? Is there any best practice number of VM in Hyper V for VMotion to work efficiently?

Hi Admin,

Hope you're doing well.

1. Yes, Hyper-V can use both general-purpose clustering with a file share witness and scale-out clustering simultaneously. Scale-out clustering is typically used for scenarios where you need to scale the virtualized workload across multiple nodes for increased performance and availability.
2. Similarly, Hyper-V can host SQL Servers using scale-out clustering with a file share witness. SQL Server itself can also utilize scale-out clustering for high availability and load balancing of database workloads. Both technologies can coexist and complement each other to provide robust infrastructure for SQL Server deployments.
3. Veeam Backup can work effectively with SQL Server deployments using scale-out clustering, both inside and outside Hyper-V environments. Veeam provides comprehensive backup and recovery solutions that can seamlessly integrate with clustered environments to ensure data protection and availability.
4. Integrating Hyper-V clusters hosted on VMware using technologies like VMotion and Disaster Recovery Manager can provide additional flexibility and redundancy to your virtualized environment. It adds an extra layer of virtualization abstraction but can offer advantages in terms of workload mobility, resource optimization, and disaster recovery capabilities.
5. The number of VMs supported by a Hyper-V license doesn't necessarily dictate the optimal number of VMs for VMotion or efficient Hyper-V operation. The optimal number of VMs depends on various factors such as hardware resources, workload characteristics, performance requirements, and management overhead. VMotion capabilities may be limited by hardware resources and network bandwidth rather than licensing constraints. It's essential to design your Hyper-V environment based on workload requirements and best practices to ensure efficient operation and VMotion capabilities.

Answer 2

Is there a reference table to show how much cpu and memory and disk space for different number of VM to work properly in Hyper V and VMotion and DRM?

Answer 3

Hi Admin,

Unfortunately, I haven't found any documentation stating this yet.

Answer 4

One of reason is that No head of IT and No manager think and require these in this world when no knowledge in mind.

Another reason is that people like to use tight budget as reason.

Third reason is that this is conceptual integration similar with common sense to integrate network devices with the knowledge.

This is basic thing to have high availability many years ago in 2008 or even earlier.

When there is clear documentation, there will be no business made.

Documentation may be internal documents that never found.

Documentation is made by yourself, otherwise no effort and no money paid.

This is the job of consultant doing. Of course, no one made documentation. It has been in somewhere of company that you have never found.

If you afraid of short sighted, then you had better change to non-IT careers.
