With release of vSphere 7, VMware takes NVMe-oF mainstream

VMware has added support for shared storage using NVMe-oF technology with the release of vSphere version 7. This represents an important moment for IT infrastructure design because NVMe over Fabrics can dramatically accelerate data storage environments. IT leaders, if they haven't already, need to understand what this development means to their environments and how to prepare for the adoption of NVMe-oF. By now, you are probably familiar with NVMe technology. For those who need a quick refresher, NVMe is an open logical device interface designed to access nonvolatile storage media such as flash storage or SSDs attached via PCIe. Because this interface standard is designed for flash storage rather than much slower-spinning hard drives, the NVMe protocol maximizes the performance benefits of flash, significantly reducing I/O latencies and increasing performance. NVMe-oF technology extends the low-latency performance of NVMe over the entire storage network. VMware's announcement calls out its new support for NVMe over Fibre Channel...
