Most of the SAN is based on SSDs, and the rest is enterprise SAS disks. I have mostly discounted PCIe based flash on account of the problems with host CPU usage

Are you going straight from ms latency (spinning rust or network) to RAM, or do you have some us latency SSDs in there too? Because it sounds like a perfect application for a TB or so enterprise drive.

The problem is if you need 800 GB per VM. Not many physical machines can host a plausible number of VMs regardless of the Hypervisor at that rate
As you don’t ask, I will tell you ??? the servers in question run financial industry applications and the RAM is used for in memory database functions. The central data warehouse has ~800 TB of data, so 800 GB is not really big by comparison. Anyways, the desire is for latency in the microsecond range for calculations across arbitrary portions of this data - not always possible, but it does keep life interesting

Impressive numbers. I won’t even ASK what you need 800GB of memory for.
In terms of VMs, 800GB of memory on ESX Server… no problem.
