I'd like to use BMR (p2v), and am wondering what the performance limitations are. I've read several helpful guides/rules-of-thumb on reasonable performance for client-to-grid, and grid-to-grid (per node), but have seen very little about BMR performance, what impacts it, and how to maximize it.
My first thought is that target (recovery host) disk I/O would very quickly become the limitation; but that restore data transfer rates would be much higher than backup operations, even with 5+ grid nodes. If that's accurate, that would raise a second question of what kind of restore performance is possible with high-speed storage (e.g. pv2 into a VBlock environment).
I have seen what happens when you have low ram.... Slow BMR restores... I have no formula for how much ram. If you can add more ram temporarily it won't hurt!
