Corosync performance tuning on 10Gbe

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

I run 3 nodes corosync cluster with cman, and above it run qpidd cluster mode service.
All the packages is from CentOS 6.5 repo and MRG clone repo, http://glitesoft.cern.ch/cern/mrg/slc6X/x86_64/RPMS/.

I test the cluster system with qpid-send and qpid-receive tools, the max bandwidth is about 117-119MB/s.

When I run standalone qpid performance test, the bandwidth will reach more than 9Gb/s, so I think the operating system and hardware tuning is good.

Corosync' s totem protocol has many options,  maybe the default configuration is suit for Gbe network, could you give any advices, let corosync cluster run full speed on 10Gbe?

Thanks in advance.

Bests.
An Yang
