<div>
checked those links.. just general concept<br />
<br />
<br />
&nbsp;for instance if we put 0 in : Host &nbsp;Failures Cluster tolerates <br />
<br />
there will be no reservation of resources for the hosts, they can provide up to 100 % of resources available<br />
<br />
and &nbsp;if one ESX fails, then VMs that can be restarted on other ESX hosts they will be restarted and the ones that do not find enough Resources will not be restarted. ?<br />
<br />
for other options:<br />
<br />
Cluster Resources Percentage: this is clear<br />
Slot Policy (Power on VMs) : this is <b>NOT</b> clear<br />
<br />
Dedicated Failover Hosts : I believe they mean by putting ESX host as spare, it will not be used at all unless one of the ESX hosts in production fails<br />
<br />
Performance Degradation VMs tolerate : &nbsp;is the degradation on the VM or on the ESX host ? I believe they mean degardation on the ESX Host

Thank you Guys...<br />
I will come back to this &nbsp;topic when I re-use the LAB

vSphere

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.
