NVM Express over Fabrics (NVMe-oF) is the concept of using a transport protocol over a network to connect remote NVMe devices, contrary to regular NVMe where physical NVMe devices are connected to a PCIe bus either directly or over a PCIe switch to a PCIe bus.
NVMe over Fabrics refers to the ability to utilize NVMe protocol over existing network infrastructure like Ethernet (Converged or traditional), TCP, Fibre Channel or InfiniBand for transport (as opposite to run NVMe over PCI). NVMe is SAN block level data storage protocol.
NVMe-oF: an equivalent mechanism, exposing block devices as NVMe namespaces over TCP, Fibre Channel, RDMA, &c., native to most operating systems; Loop device: a similar mechanism, but uses a local file instead of a remote one; DRBD: Distributed Replicated Block Device is a distributed storage system for the Linux platform
It is a general-purpose enterprise storage system with two controllers for SAN protocols such as Fibre Channel, iSCSI, SAS and InfiniBand (includes SRP, iSER, and NVMe over Fabrics protocol). NetApp E-Series platform uses proprietary OS SANtricity and proprietary RAID called Dynamic Disk Pool (DDP) alongside traditional RAIDs like RAID 10, RAID ...
A community of developers from hardware manufacturers, software vendors, system integrators, government agencies and academia continue to work on OFED. The OpenFabrics Alliance provides architectures, software repositories, interoperability tests, bug databases, workshops, and BSD- and GPL-licensed code to facilitate development.
NetApp FAS3240-R5. Modern NetApp FAS, AFF or ASA system consist of customized computers with Intel processors using PCI.Each FAS, AFF or ASA system has non-volatile random access memory, called NVRAM, in the form of a proprietary PCI NVRAM adapter or NVDIMM-based memory, to log all writes for performance and to play the data log forward in the event of an unplanned shutdown.
EDSFF provides a pure NVMe over PCIe interface. One common way to provide EDSFF connections on the motherboard is through MCIO connectors. EDSFF SSDs come in four form factors: E1.L (Long) and E1.S (Short), which fit vertically in a 1u server, and E3.L and E3.S, which fit vertically in a 2u server. [2]
Servers may access storage from multiple storage devices over the network as well. SANs are often designed with dual fabrics to increase fault tolerance. Two completely separate fabrics are operational and if the primary fabric fails, then the second fabric becomes the primary.
