Hello, > I'm curious however if the ARM servers are better or not for this use case (object-storage only). For example, instead of using 2xSilver/Gold server, I can use a Taishan 5280 server with 2x Kungpen 920 ARM CPUs with up to 128 cores in total . So I can have twice as many CPU cores (or even more) per server comparing with x86. Probably the price is lower for the ARM servers as well. 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: martin.verges@xxxxxxxx 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.
