How can i test CEPH Bonding network

[TND]

Hello,

I'm using Proxmox + CEPH + Switch Cisco 3064x

I was set MTU to 9000 and bonding LACP 2 port 10gbps for CEPH Only.

How can I verify it can reach 20gbps speed?

Thank you!

You can use iperf, but it's no guarantee you reach it with CEPH.

Iperf will only use on a link because of the balancing algo of LACP.
LACP uses the source and the dest as hash input.
Iperf test is static one source on one target.
Ceph uses different sources and dest so LACP will work.
