Server virtualization technology: virtual machine optimization tips

Virtual infrastructure often suffers from inefficiencies in simple solutions. The lack of virtual machine execution hinders the popularity of virtualization technology. The following top ten virtual machine optimization tips can help users easily solve every problem. The ten tips outlined in this article improve efficiency, reduce unexpected downtime and make your virtualization efforts worthwhile.
1. Replacing Hardware

While using the latest hardware systems on your virtual infrastructure can significantly optimize performance, upgrading hardware is primarily an upgrade to the firewall and BIOS. Track key upgrades in both areas and ensure regular patch maintenance of hardware. Hardware patch maintenance is often overlooked by users as part of the overall support plan. Ignoring the patching of hardware can lead to system failures or security breaches. Performance optimization is often a positive effect of hardware updates.

2. Host License Authorization

Host license authorization does not improve performance. However, purchasing licenses from your vendor or extending the license life can release features that are not available in the free or standardized versions. For example, upgrading from VMware vSphere Enterprise to Enterprise Plus can provide scalability features that greatly extend the performance of hosts and virtual machines.

3. Private migration network

When configuring the virtual infrastructure, be sure to pay special attention to the network settings. Create a separate network for the migration of workloads between hosts, an internal private network. This private network should have GB or multiple GB capacity. This independent performance creates a network between virtual host systems, providing a fast and secure foundation for workload and storage migration.

4. Separate Disk Image

When creating multiple virtual hard disks for a single virtual machine, the default behavior is to ensure that all virtual hard disks on the same LUN or disk array are placed together. . Separating these drives will give faster hard drive feedback. For example, dividing a Windows server into C: and D: virtual hard disks on different LUNs can achieve better performance.

5. Limited Virtual Central Processing

Perhaps the most insufficiency of all virtual machine optimization is the idea of ​​reducing the number of virtual CPUs to improve virtual machine performance. But it is true. There is no need to go through complex algorithms, just accept the fact that each virtual machine's individual virtual CPU can improve performance, because doing so can reduce the latency of host resources. If a virtual machine with multiple processors experiences performance problems and you are unable to find out why, reducing the number of virtual CPUs to two or one can achieve performance gains.

6. Thin Provisioning

Streamlined configuration from storage is a good idea. This can better improve the utilization of storage resources and transfer storage processes from the virtual infrastructure to the storage area network. While virtualization vendors claim that thinning virtual infrastructure configurations will not degrade performance, storage experts will tell you that storage infrastructure can handle system issues more efficiently.

7. Grading Service Levels

This optimization approach seems obvious, but it is not. Divide your virtual machine service levels into three different levels of testing, development, and production. Administrators should be able to logically and physically differentiate between different service levels so that each application environment can remain independent of each other. Test systems and R&D systems have a very significant negative impact on the production system. Some administrators separate all aspects of their application environment: storage, networking, and peripheral systems. Web Teaching Network

8. Virtual Machine Naming

This method may surprise you, but by better naming the virtual machine, the efficiency of these virtual machines will be significantly improved. . For example, if your virtual machines are named like VMDTTW01, VMDTDW01, and VMDTTV01, you can see how the administrator made mistakes when managing, patching, rebooting, and repairing those systems. Mixing the name of a virtual machine or starting a similar name makes support more difficult. It will also make the discussion of the system more complicated.

9. Templates

Virtual machine templates allow administrators to quickly configure virtual machines. Fast configuration improves efficiency. Increasing the frequency of using templates is a virtual machine where templates can be easily converted to upgrade patches, new software installations, and password changes. The new virtual machine created from the template can be synchronized with the changed environment.

10. Host Mode

Compared to any other virtual solution, VMware is the concept of host mode. Host mode allows administrators to create host systems with higher efficiency and continuity. With host mode, administrators can create new hosts that match virtual LAN and storage configurations in seconds or create them by compressing files without stepping.
