For context, I'm working in cloud infrastructure. Due to customer demand (esp. from customers with large in-memory DBs), our newest set of ultra-large VM flavors goes up to 3 and 6 TiB RAM. I'm not directly involved with compute, but from what I gather, it's an interesting challenge esp. on the operations side. You can migrate a 4 GiB VM in a pinch if the hypervisor is looking bad. Migrating a 6 TiB VM, however, takes a substantial amount of time (22 minutes if you have a 40 Gbps link and can saturate it, which you usually can't).
