[LU-6786] Performance test for DNE2 on OpenSFS cluster

Blocker — Thu, 16 Jul 2015 15:03:23 +0000

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.

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.
Configure clients with multiple mountpoints to allow more concurrent metadata RPCs
For each test create a single directory striped over all MDTs
Create 20000 files per client within the striped directory, measure aggregate create rate.
Unlink all files created by each client, measure aggregate unlink rate.
