Thank you totallytonto. &nbsp;I just want to make sure I do not over-allocate my VM's when planning how many VM's I can have given the resources and cause performance issues.

Thank you totallytonto.  I just want to make sure I do not over-allocate my VM's when planning how many VM's I can have given the resources and cause performance issues.

<div class="content wysiwyg-content">
If I am allocated a total of 96GHz CPU from my cluster of hosts and I have 9 VM's configured with 2GHz/Dual Core. &nbsp;Am I using 18GHz of my total or 36GHz of my total allocated CPU? Or does the extra cores use more memory? &nbsp;<br />
<br />
In other words how does adding cores affect the resources given to me?

VMware Host Resource Utilization

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.

Server Hardware

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.
