Appreciate the input. Looking at those articles they make me feel like the 40G they are talking about is 4x Bonded 10G connections. Im looking at 40Gbps without bonding for throughput. Is that still the same? [ https://www.fs.com/products/29126.html | https://www.fs.com/products/29126.html ] Yep most of this is based on the white paper with a few changes here and there.

In ceph a 50% of the latency comes from Network commits and the other 50% from disk commits.

They just need 4 cores / 16GB RAM and 2x128GB SSD or NVME M2 . _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
