Abstract

SMB 3.0 has been growing in popularity for critical applications in Windows environments. It can be deployed on standard or RDMA networks. Previous presentations have shown excellent performance for SMB Direct on InfiniBand but have not directly compared InfiniBand to 40Gb RoCE Ethernet or non-RDMA networks. Mellanox presents SQL Server benchmark results that compare SMB 3.0 performance on FDR 56Gb InfiniBand with 10 and 40Gb Ethernet using both RoCE (RDMA on Converged Ethernet) and non-RDMA TCP/IP, including IOPS, throughput, latency, and CPU utilization.

Learning Objectives

SMB Direct performance on FDR InfiniBand
SMB Direct on 40GbE, RoCE and TCP
SMB Direct on 10GbE, RoCE and TCP
IOPS, throughput, latency, and CPU utilization comparisons
