NVMe over Fabrics (NVMe-oF) is a network protocol that allows solid-state storage devices to communicate with the host computer using the NVMe protocol. This technology enables fast data transfer between the host and the storage device over a network, making it ideal for data centers or cloud-based storage systems.
How does NVMe-oF work?
NVMe-oF works by creating a communication bridge between the host computer and the target storage device or system. The protocol uses a message-based command to facilitate data transfers between the devices. The NVMe-oF specification allows for various methods of carrying data, including Ethernet, Fibre Channel (FC), and InfiniBand.
Benefits of NVMe-oF
- Reduced Latency: NVMe-oF significantly reduces latency by enabling direct access to shared storage devices over a network.
- Improved Performance: This technology enhances the performance of storage devices by reducing the communication overhead that comes with traditional data transfer protocols.
- Increased Scalability: NVMe-oF extends the benefits of NVMe technology to a large number of devices, enabling improved overall performance and productivity.
What is NVMe protocol?
NVMe is a storage protocol that was developed to improve the efficiency and performance of solid-state storage devices. It is designed to take advantage of the low latency of modern solid-state storage drives and uses a streamlined interface to significantly reduce overhead and boost performance.
What is a network fabric?
A network fabric refers to a high-speed, interconnected network that provides a reliable communication channel between devices, components, or systems. It typically uses switches, routers, and network cards to connect devices, enabling them to communicate with one another.
NVMe over Fabrics (NVMe-oF) is a network protocol that enables fast and efficient data transfer between the host computer and solid-state storage devices or systems. It reduces latency, enhances performance, and increases scalability, making it ideal for data centers and cloud-based storage applications.
