Associates physical paths with logical devices.Manages claiming and unclaiming physical paths.The NMP provides many capabilities for the ESXi hypervisor and how it interacts with storage, such as: There are two sub-plugins that are provided for by NMP:īoth of these sub-plugins (SATP and PSP) can be provided by VMware or a third-party provider. It is an extensible module that enables having sub-plugins controlled by the module. The Native Multipathing Plug-in (NMP) is the plugin included with ESXi that handles multipathing by default. Let's first take a look at the native storage plugin, which is a generic multipathing module provided by default by VMware, prior to and including ESXi 6.7 and higher. The PSA is a modular framework built on open standards that allows for coordinating the software modules that are responsible for multipathing operations. ![]() How does VMware ESXi handle storage management, specifically multipathing? VMware makes use of what is referred to as Pluggable Storage Architecture (PSA), which is a special VMkernel layer component. ESXi supports the NVMe protocol to connect to local and networked storage devices. With NVMe, production workloads benefit from the extremely low latency, high-bandwidth, and queue-depth advantages it offers. NVMe is actually a storage protocol designed specifically for very high-performing, multi-queue storage communication. ![]() NVMe devices have become increasingly popular across the board in the modern data center and provide incredible performance advantages over traditional spinning disk and even flash storage.
