Who doesn’t loves a high performing Ceph storage cluster. To get this you need to tame it , i mean not only Ceph tuning but also Network needs to be tuned. The quickest way to tune your network is to enable Jumbo Frames.
What are they :
They are ethernet frames with payload more than 1500 MTU
Can significantly improve network performance by making data transmission efficient.
Requires Gigabit ethernet
Most of the enterprise network device supports Jumbo Frames
Some people also call them ‘Giants’
Enabling Jumbo Frames
Make sure your switch port is configured to accept Jumbo frames
On server side , set your network interface MTU to 9000
# ifconfig eth0 mtu 9000
Make changes permanent by updating network interface file and restart network services
