    Description

      The performance testing is intended to measure create and unlink workload scaling as the number of MDS nodes and MDTs is increased. Testing will be done with a single MDS/MDT to provide baseline performance, and then the number of MDTs will be increased to show performance scaling. Testing will be done with both a single MDT per MDS as well as multiple MDTs per MDS to explore likely deployment configurations in production environments.

      1. Configure Lustre with 1, 2, 3, then 4 MDS nodes, each with 1, 2, 3, 4 MDTs per MDS, with the number of clients available on the OpenSFS test cluster.
      2. Configure clients with multiple mountpoints to allow more concurrent metadata RPCs
      3. For each test create a single directory striped over all MDTs
      4. Create 20000 files per client within the striped directory, measure aggregate create rate.
      5. Unlink all files created by each client, measure aggregate unlink rate.
