Is vSphere 5.5 supported?
The End of General Support for vSphere 5.5 is September 19, 2018. To maintain your full level of Support and Subscription Services, VMware recommends upgrading to vSphere 6.5, vSphere 6.7 or to a newer version.
What is the minimum number of ESXi hosts per cluster?
ESXi 6.0 or later is required. A minimum of three ESXi hosts is strongly recommended. Each vCenter HA node can then run on a different host for better protection.
How does ESXi cluster work?
vSphere HA clusters enable a collection of ESXi hosts to work together so that, as a group, they provide higher levels of availability for virtual machines than each ESXi host can provide individually.
What is ESXi cluster?
A cluster in vSphere is a collection of ESXi hosts configured to share their resources. Clusters are used to enable some of the more powerful features in vSphere, such as High Availability (HA), Distributed Resource Scheduler (DRS), Fault Tolerance (FT), and vMotion.
How many VMs can I run per core?
The maximum number of virtual processor sockets assigned to a VM is 128. If you want to assign more than 128 virtual processors, configure a VM to use multicore processors. The maximum number of processor cores that can be assigned to a single VM is 768 in vSphere 7.0 Update 1.
What’s the latest version of VMware?

Can vCenter 6.5 Manage ESXi 5.5 hosts?
vCenter Server 6.5 can manage ESXi version 5.5 or 6.0 hosts in the same cluster with ESXi 6.5 hostsvCenter Server 6.5 cannot manage ESXi 5.1 or earlier hosts.
How do I move esx05 to the compatibility cluster?
Move ESX05 into the compatibility cluster while it is in maintenance mode with no VMs. Configure and thoroughly test ESX05 (see topic below). vMotion some VMs onto ESX05, in preparation for upgrading ESX04 (the next lower generation server) next.
What is a VMware cluster and how does it work?
Once created, a vSphere cluster enables “cluster only” features such as HA (high availability) and DRS (distributed resource scheduler). Each of these features contributes to the tolerance of the VMware cluster withstanding failures as well as distributing resources across the VMware ESXi hosts.
Can You overallocate RAM on an ESXi host?
Note: You CAN overallocate RAM on ESXi hosts. They will page the less-used memory to disk. This normally won’t hurt performance much as long as you don’t over-allocate too many resources.
What is the risk of a VMware vSphere ESXi upgrade?
What is the risk of a vSphere ESXi upgrade? First, heads-up. You can’t upgrade directly from 5.5 to 6.7. You will need to upgrade to 6.0 or 6.5 first, then perform the jump to 6.7. The steps for vSphere ESXi are the same. vCenter can be a pain to upgrade.
