FlexSDS is a high-performance storage solution designed for HPC, cloud computing, edge computing and databases. It offers high availability, scale-out, redundant and auto-recovery storage options through n-ways replication or EC (erasure coding). Users can create single-node, two-node HA, or multi-node storage clusters and export dynamic volumes to VMWare vSphere ESXi via NVMe-oF, iSER and iSCSI.
This chapter explains how to set up NVMe-oF, iSER and iSCSI adapters in ESXi and connect to FlexSDS’s NVMe over Fabrics, iSER and iSCSI volumes. It also compares the performance of NVMe-oF, iSER and iSCSI interfaces, with NVMe over RDMA and iSER showing much higher performance than iSCSI and NVMe over TCP due to its use of RDMA transport, as that enables full stack of kernel bypass, zero copies of FlexSDS software.
This document provides step-by-step guide for build FlexSDS high availability and scale-out storage cluster for VMware vSphere, and exporting storage service via NVMe-oF, iSER or iSCSI.
