Are you looking for a new CPU to use for virtualization? If so, you’re in luck! In this blog post, we will be discussing the best CPUs for virtualization. We’ll be covering both consumer and enterprise processors, so no matter what your needs are, you’ll find the perfect option. So without further ado, let’s get started!
Here’s The Shortlist To Save Your Time:
7 Best CPUs for Virtualization Available In The Market
5 Things You Must Know While Choosing The Best CPUs for Virtualization
1. Know your workloads
It’s important to know what you need from your CPU cores and how much money you have allocated for this investment. Why? Well because if you buy 16 core CPUs now and later on discover that what you really need is only 8 cores, then those other CPU cores will be a total waste of money.
2. Consider future workloads and compatibility
When you are buying CPUs for virtualization, it’s always good to have some headroom so that your VM Host can also run other workloads on the same host. For example, if you buy Intel Xeon E5 2600 series, then these CPUs will work on any server from 2011 onward. However, if you consider using a Quad socket system, then make sure that not only will your current but also future workloads be compatible with this solution.
3. Know what CPU sockets exist in your servers
An important thing is to know which CPU architectures are supported by the CPU sockets in your server chassis. It might happen that you decided to save some money by getting a used server with older CPUs, but didn’t know about the socket type. Then you find out that not only are your current CPUs too slow, but this server will also become obsolete sooner because it won’t support future CPU architectures.
4. Know what kind of NUMA architecture exists in your servers
Non-uniform Memory Access (NUMA) is an efficient way to increase performance using multiple processors in a single system through Local memory access. But since allocating local memory for virtual machines can be difficult, VMware introduced NUMA spanning which enables virtual machines to span multiple physical CPUs and have access to processors’ local memory or remote memory depending on their resource usage profile. Just keep in mind that if your server has a NUMA architecture, then you must ensure that your VM will be allocated to the same NUMA node as the physical CPU. What this means is that if you have 2x Quad-Core CPUs in your host and they both belong to the same NUMA node, then all your VMs must also have 4 cores. This applies even if those VMs are not using their full resources at any given time of course.
5. Know what kind of Hyperthreading exists in your servers
When it comes to virtualization, hyperthreading is a big help since it effectively doubles the amount of vCPUs available on a single socket. Be careful though because not all CPUs offer hyperthreading and some even implement an alternative technology such as Turbo Boost which can effectively increase the number of cores available for virtual machines.
Why Do You Need CPUs for Virtualization
1. Allows for scalability
CPUs are integral in allowing businesses to be able to scale their IT infrastructure efficiently, and in a timely manner if they look into incorporating new technologies into their datacenters. If your goal is to improve VM performance and hardware utilization in terms of the number of VMs on a host machine over time, then having access to CPUs that can scale accordingly will go a long way. Not all machines with similar specs will provide the same level of performance when it comes to hosting VMs; certain CPUs may allow you to add more VMs than others depending on how they perform when running multiple applications simultaneously.
2. Allows for more processing power on a host machine
Some applications are very resource-intensive, which means they need a lot of computational power in order to run smoothly. If you’re looking to run business-critical software that requires ample resources, then it’s important that your hosts have CPUs that can handle the number of VMs you want to deploy on them over time. Not all CPUs are created equal when it comes to virtualization capabilities — so depending on what kind of software you need to run, choosing the right CPU is critical if you want your VMs to perform at their fullest potential. This is why some server manufacturers try extra hard to market certain platforms as being specifically suited for running “virtualization” or “cloud” applications — you’ll want to look for CPUs that are feature-rich enough to handle the VMs on your hosts without slowing them down.
3. Allows for more processing power on a single VM
Last but not least, your choice of CPU can also affect how much performance is available per VM on a physical host machine. Not all CPUs are created equal when it comes to virtualization capabilities — so depending on what kind of software you need to run, choosing the right CPU is critical if you want your VMs to perform at their fullest potential. This is why some server manufacturers try extra hard to market certain platforms as being specifically suited for running “virtualization” or “cloud” applications; you’ll want to look for CPUs that are feature-rich enough to handle the VMs on your hosts without slowing them down.
