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.
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]
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.
Disaggregated storage is a form of scale-out storage, built with some number of storage devices that function as a logical pool of storage that can be allocated to any server on the network over a very high performance network fabric. Disaggregated storage solves the limitations of storage area networks or direct-attached storage.
As the platform has been around since 2008, Oracle has published information related to the end-of-support for older Exadata generations. In Oracle's published document titled Oracle Hardware and Systems Support Policies, [8] they mention "After five years from last ship date, replacement parts may not be available and/or the response times for sending replacement parts may be delayed."

Management Component Transport Protocol (MCTP) is a protocol designed by the Distributed Management Task Force (DMTF) to support communications between different intelligent hardware components that make up a platform management subsystem, providing monitoring and control functions inside a managed computer system.
