This article is suitable for anyone who has decided to create or upgrade their own IT infrastructure for virtualization. It will provide specific advice on selecting a physical virtualization server, but without delving into the software.
What is server virtualization?
- Server virtualization is the software division of a server (computer) into several independent and isolated virtual machines (VMs). Simply put, it is a kind of box with several compartments inside for storing different or identical things.
The server that is partitioned into virtual machines is called the host machine (the box), and the resulting virtual machines are called guest machines (all the internal compartments).
Benefits of server virtualization
- Reducing server downtime;
- Reducing the cost of server maintenance;
- IT infrastructure can be made smaller and simpler;
- Easy cloning and migration of VMs;
- Accelerated deployment of workloads.
5 reasons why you need server virtualization:
- To save money - A productive server or cluster with VMs will be more profitable in large projects than separate servers for each task.
- To use different environments - Virtualization allows you to create multiple VMs on which you can deploy different operating systems, their versions, and incompatible software within a single server. VMs are often used as testbeds for platforms and solutions - quickly deployed, tested, and shut down.
- To isolate users, their actions and data from each other - Virtualization allows you to isolate users from each other. They can store important personal data and do whatever they want, even deploy virtualization within virtualization.
- To avoid capacity downtime - Virtualization allows you to avoid capacity downtime when, for example, only a small part of the 100% server capacity is used. For example, 10% of the server resources are allocated for mail, 30% for databases, and the remaining 60% for the terminal server.
- To evenly distribute the load between multiple servers - Virtualization allows you to avoid uneven load distribution when, for example, one server is loaded at 20%, and two neighboring servers in the rack are at 100% (and there are still a bunch of tasks in the queue).
How to choose a server for virtual machines
Choosing the right hardware for virtualization is just as important as choosing the right software. Hardware has a significant impact on infrastructure flexibility and efficiency, consolidation ratio, performance, cost of ownership, and availability of business applications. Irrelevant solutions reduce profitability and limit freedom of action.
1. Determine your needs:
- Number of virtual machines: How many virtual machines do you plan to run at once? This will affect the number of processors, RAM, and disk space you need.
- Virtual machine workload: What tasks will the virtual machines perform? It could be web hosting, database servers, software development, or gaming. Different tasks require different amounts of resources.
- Operating system: What operating systems will you use on your virtual machines? Some operating systems require more resources than others.
2. Equipment:
- Processor: Choose a processor with enough cores and clock speed to support the expected workload.
- RAM: Provide enough RAM to run all virtual machines simultaneously.
- Disk space: Choose the type and amount of disk space that meets your storage needs. SSDs offer better performance, but they also cost more.
- Network: Make sure the server has a network interface with enough bandwidth to support the traffic of your virtual machines.
3. Virtualization type:
- Hardware virtualization: Provides the best performance, but also costs more.
- Software virtualization: More affordable, but may have slightly worse performance.
- Container virtualization: Easy and cost-effective, but may not be suitable for all tasks.
4. Operating system:
- Windows Server: A popular choice for virtualization due to its flexibility and wide range of features.
- Linux: A more affordable option that offers high performance and stability.
- VMware ESXi: An enterprise-grade virtualization platform that offers a wide range of management features.
5. Additional factors:
- Reliability: Choose a server with reliable components and a manufacturer's warranty.
- Support: Make sure the server provider offers quality technical support.
- Cost: Compare prices of different servers, taking into account the cost of hardware, software, and support.
Hardware technologies for server virtualization:
For effective server virtualization, the following hardware components are required:
Processor:
- Multi-core: The number of processor cores is one of the most important factors affecting virtualization performance. The more cores, the more virtual machines can be run simultaneously.
- Clock speed: A high processor clock speed also improves virtualization performance.
- Virtualization support: Make sure your processor supports virtualization technologies such as Intel VT-x or AMD-V. This will allow virtual machines to use processor resources more efficiently.
Random Access Memory (RAM):
- Amount: The amount of RAM required for virtualization depends on the number and resource intensity of virtual machines you plan to run. As a general rule, it is recommended to have at least 8 GB of RAM for virtualization.
- Speed: Fast RAM, such as DDR4, can improve virtualization performance.
Disk space:
- Type: SSDs offer significantly better performance than hard disk drives (HDDs) and are recommended for virtualization.
- Capacity: The amount of disk space required for virtualization depends on the size of your virtual machines and their data.
Chain:
- Bandwidth: Make sure the server has a network interface with enough bandwidth to support the traffic of your virtual machines.
- Gigabit Ethernet: Gigabit Ethernet or better network interface is recommended for virtualization.
Additional components:
- Hardware RAID: A RAID array can provide data reliability and availability for your virtual machines.
- Backup power supply: A UPS (uninterruptible power supply) can protect your virtual machines from power surges and outages.
Recommendations:
- Choose a server with quality components from reliable manufacturers.
- Don't skimp on RAM and disk space.
- Consider using hardware RAID and a UPS for increased reliability.
- Update your server firmware and software regularly.
Remember that choosing the right hardware technologies for virtualization is essential to ensuring optimal performance, reliability, and security of your virtual machines.
