Abstract
Once a ceph cluster has been assembled, how do you know the bandwidth capabilities of the cluster? What if you want to compare your cluster to one of the clusters in a vendor whitepaper? Use the Ceph Benchmarking Tool (CBT). Learn about CBT so that you can measure the performance of your cluster. You can simulate Openstack, S3 /Swift via CosBench, or an application written against the librados API. The tool is config file based with parametric sweeping to test a range of values in one file, ties in with collectl and blktrace, and will re-create a ceph cluster if desired.
