I'm preparing to upgrade from VShpere 4.1 to 5.0. We have VMware essentials plus. Our environment has 3 hosts and I'm planing on adding memory to each host while I'm at it. From what I can tell we are limited to a total of 192 GB in our VM environment. So if my math is right I would need 64 GB per host.
I'm wondering about fail over. If I put extra #GB in each host and one host fails will VMware see the extra memory and make it available?

No, the only memory available is whatever is 'online' by active, workable hosts. You do have a max of 192GB, but if you don't have that much available, it won't get 'seen'....just whatever's remaining. You only get 'dinged' by what is used by POWERED ON VMs, as well.

The vRAM limit is 192GB in the pool, which is the total memory of VMs which are powered ON.
Essentials is limited at 32GB per processor, total 64GB per host.
I'm looking to add extra memory just in case a host goes down.
Would be beneficial to add more than 64 GB per host as my hosts have 2 processors each?
I'm wondering if VMware will see that the host has failed (two processors) and allow the "extra memory" that I added in the other two hosts to be used.

if you upgrade you servers beyond 64GB, you will be above the vRAM cap of 192GB for Essentials for all three servers.
If upgrading your memory in the servers, you would have to Upgrade to an Acceleration Pack to get you to Standard Level, and then add Additional Processor Licenses to get you to the appropriate level of allowed ram.
