English to French Tech/Engineering IT (Information Technology) data management solutions

XXXX can be configured to **scale** both horizontally and vertically with the addition of disk for larger volumes of data and addition of extra CPUs to a central server.

Je comprends le sens en anglais: 'to scale horizontally (or scale out): to add more nodes to a system' et 'to scale vertically': to add resources to a single node in a system, typically involving the addition of CPUs or memory to a single computer.
Quels sont les equivalents en français ? Peut-on parler de configuration modulaire ou évolutive ? Merci
