Indeed, I've no idea if those numbers are correct or not. But I think I can still answer the actual concern based on more general knowledge.
If you're talking about migrating an existing Socket customer, then that's not how migration from Sockets to VUL works. First, you don't need to purchase new licenses, as we will convert those existing Socket licenses into VUL. Second, there's the migration policy that ensures migrating customers see little to no increase in their annual Veeam renewals costs (depending on the edition). This is achieved by providing them a discount in perpetuity (for the life of customer) as to convert the remaining value of the "perpetuity" factor of their existing Socket license.
If you're talking about a brand new prospect: normally you should drive all your clients to VUL Subscription, which is our primary offering. It is priced most attractively comparing to other options to encourage buying behavior. While VUL Perpetual is designed for rare scenarios when prospects are subject to regulation requiring CAPEX purchases (usually governments) in which case Veeam sales team is always involved. So VUL Perpetual deals are rarely done with simple multiplication of MSPR: this same types of customers always expect massive upfront discounts, so list price no longer means all that much.
Most importantly though, here's the bigger picture you are missing above: 64 VMs on 3 sockets means more than 21:1 VM to Socket ratio, which is insane comparing to industry average. So what we're looking at here is an outlier, and its crazy density is exactly what makes Socket license looks so good here, not surprisingly. However, the reality is that half of the hypervisor hosts protected by Veeam today have less than 6:1 density ratio, which would in turn require 12 sockets to run the same number of VMs, resulting in 4 times higher Socket price.
You're correct that for customers with very high VM per Socket density, our Socket licensing provides a deal that is too good to be true. But this gives all the more reasons for you to get them on Veeam while we still carry Socket licenses on our books! Everyone wins, right?
