(thread: Maybe some tuning for bonded network adapters)
CEPH works well with LACP bonds. The problem described in that thread is
the fact that LACP is not using links in a round robin fashion, but
distributes network stream depending on a hash of certain parameters
like source and destination IP address. This is already set to layer3+4
policy by the OP.
Regarding the drops (and without any experience with neither 25GBit
ethernet nor the Arista switches):
Do you have corresponding input drops on the server's network ports? Did
you tune the network settings on server side for high throughput, e.g.
net.ipv4.tcp_rmem, wmem, ...? And are the CPUs fast enough to handle the
network traffic?

Burkhard
