A few years back I know I worked with a tool from VMWare that ran on my physical servers and we used the data to determine how many hosts I needed and how many vms to go on each host. &nbsp;Does anyone know what that tool is called and where I can download it?<br />
<br />
Thanks!

Tool to determine how many vmware hosts are needed

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.
