Even if they would be cheaper, which I strongly doubt, you will get less performance out of them. More cores won't give you any benefit in Ceph, but having much faster cores is somewhat of a game changer. Just use a good AMD Epyc for best price/performance/power ratio. > Has anyone tested Ceph in such scenario? Is the Ceph software really > optimised for the ARM architecture ? What do you think about this ? If you choose ARM for your Ceph, you are one of very very few people and will most properly hit some crazy bugs that will cause trouble. A high price to pay in my opinion just for an "imaginary" performance or power reduction benefit. Storage has to run 24*7 all year long without a single incident. Everything else in my world is inacceptable. -- Martin Verges Managing director Mobile: +49 174 9335695 E-Mail: [email protected] Chat: https://t.me/MartinVerges croit GmbH, Freseniusstr. 31h, 81247 Munich CEO: Martin Verges - VAT-ID: DE310638492 Com. register: Amtsgericht Munich HRB 231263 Web: https://croit.io YouTube: https://goo.gl/PGE1Bx Am Di., 24.
