With VMware ESXi 5. X, we run a maximum of 24 VMs on each node, usually working with about 15 VMs per host.

How many VMs can I run on a physical server?
You may be able to fit as many as 100 VMs on a single host, or as few as two.
How many VMs can I run on ESXi free?
How many VMs can I run on ESXi free? There is no limit to the number of VMs you can run on ESXi free, but keep in mind the limitation of 480 logical CPUs. You cannot deploy more than 480 logical CPUs on an ESXi host.
What is the maximum number of virtual machines?
A: The max is 50, which is the same number of virtual machines that can be in a single cloud service (see the Microsoft Azure Virtual Machine Limits page). However, note that all virtual machines must reside in the same cloud service and therefore the same Azure scale unit (cluster).
Is an ESX host a physical server?
A Host is the virtual representation of the computing and memory resources of a physical machine running ESX Server.
What is the maximum number of virtual machines that a vSphere ESXi host can handle use of the maximum 6.0 Guide will be allowed?
Maximum number of virtual machines per host: 1024.
How many VMs can I run with 6 cores?
A good rule of thumb that we have seen empirically is that with a dual 6 core server, you may run up to 7 virtual machines and with a quad 6 core machine, you would be able to run 15 virtual machines.
How many VMs can an 8 core processor run?
Theoretically, if you have small VMs that barely use any CPU time, you could easily get 20-30 VMs from an 8-core server. However, if you have larger workloads such as a database server, you will have far fewer VMs from that same 8 core server.
How much RAM do I need for multiple virtual machines?
8 GB RAM should be good for most situations. With 4 GB you can have a problem, depending on what you intend to do with the client OS and what else the host will be used for. Most client operating systems will need at least 1 GB RAM but that only for light use. Modern versions of Windows will want more.
What is the difference between ESX and ESXi?
ESX: The functionality and performance of VMware ESX and ESXi are the same; the difference between the two hypervisors resides in their packaging architecture and operational management. VMware ESXi is the latest hypervisor architecture from VMware.
What is the difference between ESXi 6.7 and 7?
vCenter 7 supports a higher number of VMs and ESXi hosts than vCenter 6.7: In the standalone mode, vCenter 7 supports up to 2,500 ESXi hosts and 40,000 powered-on VMs (45,000 registered VMs). In the linked mode, vCenter 7 supports 15 vCenters per SSO domain, 15,000 ESXi hosts and 150,000 powered-on VMs.
Can I use ESXi without vSphere?
Yes it is possible to directly manage the ESXi host via vsphere client, but you will not be able to get the unique and good features of vCenter server like HA and DRS.
How many VMs can be created in a Availability set?
An availability set is a logical grouping of VMs that allows Azure to understand how your application is built to provide for redundancy and availability. We recommended that two or more VMs are created within an availability set to provide for a highly available application and to meet the 99.95% Azure SLA.
What is the maximum number of application VMs that you can host on one of your new servers?
To add to the above suggestions, with an exact idea of what Hardware (no. of processors and amount of ram) you can divide it amongst your Virtual machines, leaving some for the HOST too. Maximum are 384 VMs, have a look at the links above will give you good insight into it.
Which is main factor that determines the number of virtual machines?
CPU. The number and speed of host machine CPUs determine the performance of multiple virtual machines.
How physical resources are presented to multiple virtual machines?
When multiple virtual machines run on the same host, each virtual machine is allocated a portion of its physical resources. The hypervisor allows multiple operating systems to share a single hardware host.
What OS does ESXi use?
ESXi is a Type 1 hypervisor, meaning it runs directly on system hardware without the need for an OS. Type 1 hypervisors are also referred to as bare-metal hypervisors because they run directly on hardware.
What is the maximum RAM supported by ESXi 6.5 for virtual machine?
EXPLANATION. The maximum memory for each virtual machine has increased from 4 TB in Vsphere 60o to 6 TB in Vshere 6.5.
How many virtual cores does a physical core have?
For vSphere 6.0, there is a maximum of 32 vCPUs per physical core, and vSphere administrators can allocate up to 4,096 vCPUs to virtual machines on a single host, although the actual achievable number of vCPUs per core depends on the workload and specifics of the hardware.
Can I run multiple virtual machines simultaneously?
Using virtualization software, you can run multiple operating systems on one physical machine. The technology is now mainstream enough that it is a built-in feature in Windows 7 Professional (and above) and in Windows Server 2008 R2.
How many virtual machines can I run on 8GB RAM?
Virtual Machines need memory too. 8GB would work for a couple of normal machines and may a third small one if 8GB is your maximum memory.
How many virtual processors are in a core?
Each core very safely support 8 virtual processors. Logical processors are abstractions of time of the physical processors and really muddy the thinking as they apply to a physical machine one way and to a hypervisor in a different way.
Is vCPU the same as core?
Each vCPU is seen as a single physical CPU core by the VM’s operating system. If the host machine has multiple CPU cores at its disposal, then the vCPU is actually made up of a number of time slots across all of the available cores, thereby allowing multiple VMs to be hosted on a smaller number of physical cores.
How many virtual machines can I run on 16GB RAM?
16 GB RAM is not a big amount. A maximum of 4 VMs should be possible, but in such a case each system did not have an own processor, if there is a heavy load on the VMs this did not work very well.
Do I need 32GB RAM for virtual machines?
Yes 32GB would be recommended however if it is just 1 VM and you are not doing anything intensive on it, you will be fine with 16GB.
