Mellanox network adapter and switches supported remote direct memory access (RDMA) and RDMA over Converged Ethernet. Product names included: The ConnectX product family of multi-protocol ASICs and adapters supports virtual protocol interconnect (VPI), enabling support for both Ethernet and InfiniBand traffic at speeds up to 200 Gbit/s. The ...
At introduction, typical speeds were 1 Gbit/s for Ethernet SFPs and up to 4 Gbit/s for Fibre Channel SFP modules. [4] In 2006, SFP+ specification brought speeds up to 10 Gbit/s and the later SFP28 iteration, introduced in 2014, [5] is designed for speeds of 25 Gbit/s. [6] A slightly larger sibling is the four-lane Quad Small Form-factor ...
Nvidia BlueField is a line of data processing units (DPUs) designed and produced by Nvidia. Initially developed by Mellanox Technologies, the BlueField IP was acquired by Nvidia in March 2019, when Nvidia acquired Mellanox Technologies for US$6.9 billion. [1] The first Nvidia produced BlueField cards, named BlueField-2, were shipped for review ...
Direct attach SFP28-to-SFP28 copper cables in 1-, 2-, 3- and 5-meter lengths are available from several manufacturers, and optical transceiver manufacturers have announced 1310 nm "LR" optics intended for reach distances of 2 to 10 km over two strands of standard single-mode fiber, similar to existing 10GBASE-LR optics, as well as 850 nm "SR ...
RDMA over Converged Ethernet (RoCE) [1] is a network protocol which allows remote direct memory access (RDMA) over an Ethernet network. There are multiple RoCE versions. RoCE v1 is an Ethernet link layer protocol and hence allows communication between any two hosts in the same Ethernet broadcast domain.
At GTC2017, Nvidia presented its Volta generation of GPUs and indicated the integration of a revised version 2.0 of NVLink that would allow total I/O data rates of 300 GB/s for a single chip for this design, and further announced the option for pre-orders with a delivery promise for Q3/2017 of the DGX-1 and DGX-Station high performance ...
EZchip was later acquired by Mellanox Technologies for $811 million. [1] Mellanox developed BlueField, integrating ARM cores with the mesh interconnect of TILE, but was acquired by Nvidia in 2019 for $6.9 billion. Nvidia continues to ship BlueField products as of 2024.
Announced May 2023, the DGX GH200 connects 32 Nvidia Hopper Superchips into a singular superchip, that consists totally of 256 H100 GPUs, 32 Grace Neoverse V2 72-core CPUs, 32 OSFT single-port ConnectX-7 VPI of with 400 Gbit/s InfiniBand and 16 dual-port BlueField-3 VPI with 200 Gbit/s of Mellanox. Nvidia DGX GH200 is designed to handle ...
