Open Compute Project Spec 3.0The OCP NIC 3.0 specification extends the capabilities of OCP NIC 2.0 design specification. OCP 3.0 defines a different form factor and connector style than OCP 2.0. The OCP 3.0 specification defines two basic card sizes: Small Form Factor (SFF) and Large Form Factor (LFF). Mellanox OCP NICs are currently supported in a SFF.*

* Future designs may utilize LFF to allow for additional PCIe lanes and/or Ethernet ports,

OCP3.0

I/O Virtualization and Virtual SwitchingMellanox ConnectX Ethernet adapters provide comprehensive support for virtualized data centers with Single-Root I/O Virtualization (SR-IOV), allowing dedicated adapter resources and guaranteed isolation and protection for virtual machines within the server. I/O virtualization gives data center managers better server utilization and LAN and SAN unification while reducing cost, power and cable complexity.

Moreover, virtual machines running in a server traditionally use multilayer virtual switch capabilities, like Open vSwitch (OVS). Mellanox’s ASAP2 - Accelerated Switch and Packet Processing® technology allows for the offloading of any implementation of a virtual switch or virtual router by handling the data plane in the NIC hardware, all the while maintaining the control plane unmodified. This results in significantly higher vSwitch/vRouter performance without the associated CPU load.

RDMA over Converged Ethernet (RoCE)Mellanox RoCE doesn’t require any network configurations, allowing for seamless deployment and efficient data transfers with very low latencies over Ethernet networks — a key factor in maximizing a cluster’s ability to process data instantaneously. With the increasing use of fast and distributed storage, data centers have reached the point of yet another disruptive change, making RoCE a must in today’s data centers.

Flexible Multi-Host® TechnologyMellanox’s innovative Multi-Host technology provides high flexibility and major savings in building next generation, scalable, high-performance data centers. Multi-Host connects multiple compute or storage hosts to a single interconnect adapter, separating the adapter PCIe interface into multiple and independent PCIe interfaces, without any performance degradation. Mellanox’s OCP 3.0 Small Form Factors (SFF) cards may support up to 4 different hosts (4x4 on SFF) or up to 8 hosts on a Large Form Factor (LFF) card. The technology enables designing and building new scale-out heterogeneous compute and storage racks with direct connectivity among compute elements, storage elements and the network. This enables better power and performance management, while achieving maximum data processing and data transfer at minimum capital and operational expenses.

Mellanox Socket Direct®

Mellanox Socket Direct technology brings improved performance to multi-socket servers by enabling direct access from each CPU in a multi-socket server to the network through its dedicated PCIe interface. With this type of configuration, each CPU connects directly to the network; this enables the interconnect to bypass a QPI (UPI) and the other CPU, optimizing performance and improving latency. CPU utilization improves as each CPU handles only its own traffic, and not the traffic from the other CPU. Mellanox’s OCP 3.0 cards include native support for socket direct technology for multi-socket servers and can support up to 8 CPUs.

Accelerated StorageMellanox adapters support a rich variety of storage protocols and enable partners to build hyperconverged platforms where the compute and storage nodes are co-located and share the same infrastructure. Leveraging RDMA, Mellanox adapters enhance numerous storage protocols, such as iSCSI over RDMA (iSER), NFS RDMA, and SMB Direct to name a few. Moreover, ConnectX adapters also offer NVMe-oF protocols and offloads, enhancing utilization of NVMe based storage appliances.

Other storage related hardware offloads are the Signature Handover mechanism based on the advanced T-10/DIF implementation, and the Erasure Coding offloading capability enabling the building of a distributed RAID (Redundant Array of Inexpensive Disks).

Host ManagementMellanox host management sideband implementations enable remote monitor and control capabilities using RBT, MCTP over SMBus, and MCTP over PCIe – Baseboard Management Controller (BMC) interface, supporting both NC-SI and PLDM management protocols using these interfaces. Mellanox OCP 3.0 adapters support these protocols to offer numerous Host Management features such as PLDM for Firmware Update, network boot in UEFI driver,UEFI secure boot, and more.

Enhancing Machine Learning Application PerformanceMellanox adapters with built-in advanced acceleration and RDMA capabilities deliver best-in-class latency, bandwidth and message rates, and lower CPU utilization. Mellanox PeerDirect® technology with NVIDIA GPUDirect™ RDMA enables adapters with direct peer-to-peer communication to GPU memory, without any interruption to CPU operations. Mellanox adapters also deliver the highest scalability, efficiency, and performance for a wide variety of applications, including bioscience, media and entertainment, automotive design, computational fluid dynamics and manufacturing, weather research and forecasting, as well as oil and gas industry modeling. Thus, Mellanox adapters are the best NICs for machine learning applications.

Secure Network AdaptersMellanox ConnectX OCP 3.0 adapters implement a secure firmware update check, which means that the devices verify – using digital signatures – the firmware binaries prior to their installation on the adapters. This ensures that only officially authentic images produced by Mellanox can be installed, regardless whether the installation happens from the host, the network, or a BMC. Starting from ConnectX-6 Mellanox offers the option for Hardware Root of Trust which introduces secure boot as well.
