What it is
GreenLake puts HPE infrastructure in your datacentre and bills it by consumption. A buffer of capacity sits installed and ready, you pay for what you actually use, and the meter reads monthly.
What it is for
Data that has to stay in the building for legal or operational reasons, where demand cannot be forecast three years out.
The hardware is the same as if you bought it.
What to watch
A consumption model moves capital expenditure into operating expenditure. The arithmetic works when demand genuinely varies. Under a stable, predictable load, buying is often cheaper, and that calculation belongs before the signature.
