[cisco-voip] ESXi RAM Requirements

The tested reference solutions, I believe, take into account only the specific VM memory overhead requirements for the number and size of UC VMs that are supported by the TRC; plus the overhead requirements of ESXi itself and, I believe, a certian amount of "buffer".
The additional features that you can access with enterprise licensing (vMotion .... etc) have addition requirements that would scale beyond the minimum 4GB.

I'm trying to understand the concept of ESXi's RAM requirements, and with 5.5 VMWare says the minimum is 4GB, but they do recommend 8GB for "full features."
When I look at this one guide as an example:
It shows that 48GB of RAM is installed inside, but only 44GB is available to VMs. That makes me think Cisco is only accounting for a 4GB minimum, and not the 8GB recommended.
Is that what you read that as, as well? And how does one allocate 8GB to ESXi? Do you just not use it for your VMs and leave it on the table, a la CUC core reservation?
A little late Friday evening thoughts right before a holiday weekend. That's how you know I'm in this job deep. Thanks and have a great weekend.
