How do you implement VM resource allocation changes and migrations?

2 Define your VM resource allocation policies

After you assess your current VM resource utilization, you need to define your VM resource allocation policies, which are the rules and settings that control how much CPU, memory, disk, and network resources each VM can access and consume. You can use various methods to define your VM resource allocation policies, such as reservations, limits, shares, affinity rules, resource pools, or Distributed Resource Scheduler (DRS). You should also consider the trade-offs and implications of each option, such as the impact on performance, availability, scalability, and flexibility. By defining your VM resource allocation policies, you can ensure that your VMs have appropriate resources for their workload and priority.

3 Implement your VM resource allocation changes

After you define your VM resource allocation policies, you need to implement your VM resource allocation changes, which are the actions that modify the amount or type of CPU, memory, disk, and network resources assigned to each VM. You can use various tools and commands to implement your VM resource allocation changes, such as vSphere Client, PowerCLI, or third-party solutions. You should also consider the best practices for each type of resource change, such as the impact on performance, availability, compatibility, and security. By implementing your VM resource allocation changes you can optimize the efficiency and effectiveness of your VMs and their workload.

4 Test and validate your VM resource allocation changes

After you implement your VM resource allocation changes you need to test and validate the changes to confirm that your VMs are functioning properly and meeting your expectations and requirements. You can use various methods to test your VM resource allocation changes, such as benchmarks, stress tests, load tests, or performance monitoring. You should also consider the best practices for each type of testing, such as the scope, duration, frequency, and criteria. By testing and validating your VM resource allocation changes, you can ensure that your VMs are delivering the desired results and outcomes.

5 Plan your VM migrations

After you test and validate your VM resource allocation changes, you need to plan your VM migrations, which are the processes that move your VMs from one host machine to another within or across data centers. You can use various tools and features to plan your VM migrations, such as vMotion, Storage vMotion, or Cross vCenter vMotion. You should also consider the recommendations for each type of migration, such as the impact on performance, availability, compatibility, and security. By planning your VM migrations, you can prepare for the successful execution and completion of your VM movements.
