Configuring NVMeoF RoCE For SUSE 15
The blog is taken from Configuring NVMeoF RoCE For SUSE 15.
The purpose of this blog post is to provide the steps required to implement NVMe-oF using RDMA over Converged Ethernet (RoCE) for SUSE Enterprise Linux (SLES) 15 and subsequent releases.The blog is taken from Configuring NVMeoF RoCE For SUSE 15.
An important item to note is that RoCE requires a lossless network, requiring global pause flow control or PFC to be configured on the network for smooth operation.
All of the below steps are implemented using Mellanox Connect-X4 adapters.
