Hi We have some oldish servers with ssds - all on 25gbit nics. R815 AMD - 2,4ghz+ Is there significant performance benefits in moving to a new NVMe based, new cpus? +20% IOPs? + 50% IOPs? Jesper Sent from myMail for iOS
Depends on your current SSDs and the new SSDs. It is highly likely that most performance increase will come from choosing good new NVMe. In addition higher clock frequency will increase IO as well but only if it is a bottleneck. -- Martin Verges Managing director Hint: Secure one of the last slots in the upcoming 4-day Ceph Intensive Training at https://croit.io/training/4-days-ceph-in-depth-training.

Is there significant performance benefits in moving to a new NVMe based, new cpus?
+20% IOPs? + 50% IOPs?

Hello Jesper, Assuming your SSDs are server ones with capacitors I'd say the biggest impact will come from CPUs, up to twice lesser latency, up to twice... or maybe 1.5x more iops in parallel mode. If your SSDs are desktop then new server NVMes will be a significant improvement for writes, too. 17 февраля 2020 г. 21:54:27 GMT+03:00, jesper@krogh.cc пишет:
