PCI Express (PCIe)

Uses PCIe Gen 3.0 (8GT/s) and Gen 4.0 (16GT/s) through an x8 or x16 edge

connector. Gen 1.1 and 2.0 compatible.

Up to 100 Gigabit Ethernet

Mellanox adapters comply with the following IEEE 802.3 standards:

– 100GbE/ 50GbE / 40GbE / 25GbE / 10GbE / 1GbE

– IEEE 802.3bj, 802.3bm 100 Gigabit Ethernet

supporting all FEC modes

– IEEE 802.3ba 40 Gigabit Ethernet

– IEEE 802.3by 25 Gigabit Ethernet

– IEEE 802.3ae 10 Gigabit Ethernet

– IEEE 802.3ap based auto-negotiation and KR startup

Memory

PCI Express - stores and accesses Ethernet fabric connection information and

packet data.SPI Quad - includes 128Mbit SPI Quad Flash device

(W25Q128FVSIG device by ST Microelectronics)

VPD EEPROM - The EEPROM capacity is 128Kbit.

Overlay Networks

In order to better scale their networks, data center operators often create overlay

networks that carry traffic from individual virtual machines over logical tunnels

in encapsulated formats such as NVGRE and VXLAN. While this solves net

work scalability issues, it hides the TCP packet from the hardware offloading

engines, placing higher loads on the host CPU. ConnectX-5 effectively

addresses this by providing advanced NVGRE and VXLAN hardware offload

ing engines that encapsulate and de-capsulate the overlay protocol.

RDMA and RDMA over

Converged Ethernet (RoCE)

ConnectX-5, utilizing IBTA RDMA (Remote Data Memory Access) and RoCE

(RDMA over Converged Ethernet) technology, delivers low-latency and high-

performance over Band and Ethernet networks. Leveraging data center bridging

(DCB) capabilities as well as ConnectX-5 advanced congestion control hard

ware mechanisms, RoCE provides efficient low-latency RDMA services over

Layer 2 and Layer 3 networks.

Mellanox PeerDirect™

PeerDirect™ communication provides high efficiency RDMA access by elimi-

nating unnecessary internal data copies between components on the PCIe bus

(for example, from GPU to CPU), and therefore significantly reduces applica

tion run time. ConnectX-5 advanced acceleration technology enables higher

cluster efficiency and scalability to tens of thousands of nodes.

CPU Offload

Adapter functionality enabling reduced CPU overhead allowing more available

CPU for computation tasks.

Each adapter card includes the following interfaces:

• “Ethernet SFP28 and QSFP28 Interface”

• “PCI Express Interface”

• “LED Interface”

• “Heatsink Interface”

• “SMBus Interface”

• “Voltage Regulators”

2.1 Ethernet SFP28 and QSFP28 Interface

The network ports of the ConnectX®-5 adapter card are compliant with the IEEE 802.3 Ethernet

standards listed in

Table 7. Ethernet traffic is transmitted through the cards' SFP28 and QSFP28

connectors.

2.2 PCI Express Interface

2.3 LED Interface

There is one bi-color I/O LED per port to indicate link status. See Table 9.

Table 9 - Physical and Logical Link Indications (Ethernet Mode)

2.4 Heatsink Interface

The heatsink is attached to the ConnectX-5 IC in order to dissipate the heat from the ConnectX-5

IC. It is attached either by using four spring-loaded push pins that insert into four mounting

holes, or by screws.

ConnectX-5 IC has a thermal shutdown safety mechanism which automatically shuts down the

ConnectX-5 card in cases of high temperature event, improper thermal coupling or heatsink

removal.

2.5 SMBus Interface

ConnectX-5 technology maintains support for manageability through a BMC. ConnectX-5 PCIe

stand-up adapter can be connected to a BMC using MCTP over SMBus or MCTP over PCIe pro

tocols as if it is a standard Mellanox PCIe stand-up adapter. For configuring the adapter for the

specific manageability solution in use by the server, please contact Mellanox Support.

2.6 Voltage Regulators

The voltage regulator power is derived from the PCI Express edge connector 12V supply pins.

These voltage supply pins feed on-board regulators that provide the necessary power to the vari

ous components on the card.

3.1 System Requirements

3.1.1 Hardware Requirements

A system with a PCI Express x8 or x16 slot is required for installing the card.

3.1.2 Airflow Requirements

ConnectX-5 adapter cards are offered with two airflow patterns: from the heatsink to the network

ports and vice versa.

Table 11 provides an airflow color legend. Please refer to “Specifications” for

airflow numbers per OPN.

Table 11 - Airflow Color Legend

Unless otherwise specified, Mellanox products are designed to work in an environmentally

controlled data center with low levels of gaseous and dust (particulate) contamination.

The operation environment should meet severity level G1 as per ISA 71.04 for gaseous con-

tamination and ISO 14644-1 class 8 for cleanliness level.

For proper operation and performance, please make sure to use a PCIe x8 or x16 slot that can

supply sufficient power to your card. Refer to Section 7.9, “Airflow Specifications”, on page 71

for more power requirements.

All cards in the system should be planned with the same airflow direction.

2. Shut down your system if active.

Turn off the power to the system, and disconnect the power cord. Refer to the system documen-

tation for instructions. Before you install the ConnectX-5 card, make sure that the system is dis-

connected from power.

3.4 Bracket Replacement Instructions

The ConnectX-5 [Ex] cards are shipped with assembled high-profile brackets. If this form factor

is suitable for your requirements, you can skip the remainder of this section and move to

Section 3.5, “Installation Instructions”, on page 21. If you need to replace the high-profile

bracket with the short bracket that is included in the shipping box, please follow the instructions

in this section.

To replace the brackets you will need the following parts:

Please note that if the card is removed hastily from the antistatic bag, the plastic ziplock may

harm the EMI fingers on the networking connector. Carefully remove the card from the anti

static bag to avoid damaging the EMI fingers.

Due to risk of damaging the EMI fingers, it is not recommended to replace the bracket more

than three times.
