Comparing Lustre Performance using Myricom 10G Dual Protocol NICs

Abstract : In this paper, we look at how Lustre performs using Myricom's 10 Gb/s NICs. Lustre clients and servers can use these programmable NICs in either native Ethernet mode or in Myrinet mode. Lustre provides metrics for measuring metadata retrieval (small message) performance as well as for bulk read and write operations. We show that with multiple clients Lustre can achieve 95% of line-rate performance using Ethernet (TCP) when reading but only 50% when writing. We show that Lustre achieves a 95% of line-rate with a single client when using the NIC in Myrinet mode. In both cases, Lustre can serve up to 45,000 metadata requests per second using multiple clients.
