1.2 Features and Benefits

Table 6 - Features

Virtual Protocol

Interconnect (VPI)

VPI-enabled adapters facilitate any standard networking, clustering, storage, and

management protocol to seamlessly operate over any converged network with the

same software infrastructure.

InfiniBand Architecture

Specification v1.2.1

compliant

ConnectX-3 delivers low latency, high bandwidth, and computing efficiency for

performance-driven server and storage clustering applications. ConnectX-3 is

InfiniBand Architecture Specification v1.2.1 compliant.

PCI Express (PCIe)

Uses PCIe Gen 3.0 (1.1 and 2.0 compatible) through an x8 edge connector up to

8GT/s

10/40/56 Gigabit Ethernet

Mellanox adapters comply with the following IEEE 802.3* standards:

IEEE Std 802.3-2008 Ethernet

IEEE Std 802.3ae 10 Gigabit Ethernet

IEEE Std 802.3ba 40 Gigabit Ethernet

IEEE Std 802.3ad Link Aggregation and Failover

InfiniBand FDR

A pre-standard InfiniBand data rate, where each lane of a 4X port runs a bit rate

of 14.0625Gb/s with a 64b/66b encoding, resulting in an effective bandwidth of

54.54Gb/s.

InfiniBand FDR10

An InfiniBand transport and link layer running over a physical layer using the

PCS encoding of 64b/66b and a bit rate of 10.3125Gb/s per lane.

InfiniBand QDR

A standard InfiniBand data rate, where each lane of a 4X port runs a bit rate of

10Gb/s with an 8b/10b encoding.

Memory

PCI Express - stores and accesses InfiniBand and/or Ethernet fabric connection

information and packet data

SPI - includes one 16Mb SPI Flash device (M25PX16-VMN6P device by ST

Microelectronics)

EEPROM - accessible through the I

2

C-compatible interface. The EEPROM

capacity is 4Kb.

RDMA over Converged

Ethernet (RoCE)

Leveraging Data Center Bridging capabilities, RoCE provides efficient low

latency RDMA services over Layer 2 Ethernet.

CPU offload

Adapter functionality enabling reduced CPU overhead allowing more available

CPU

GPUDirect RDMA

Using GPUDirect RDMA, adapters can directly read and write CUDA host and

device memory, eliminating unnecessary system memory copies and CPU over-

head, resulting in significant performance improvements.

Sockets Acceleration

Applications utilizing TCP/UDP/IP transport can achieve industry leading

throughput over InfiniBand or 10 or 40GbE. The hardware-based stateless offload

engines in ConnectX-3 reduce the CPU overhead of IP packet transport. Sockets

acceleration software further increases performance for latency sensitive applica-

tions.

Quality of Service (QoS)

Support for port-based Quality of Service enabling various application require-

ments for latency and SLA

Hardware-based I/O

virtualization

ConnectX-3 provides dedicated adapter resourcesand guaranteed isolation and

protection for virtual machines within the server.

SR-IOV

ConnectX-3 Pro SR-IOV technology provides dedicated adapter resources and

guaranteed isolation and protection for virtual machines (VM) within the server.

I/O virtualization with ConnectX-3 Pro gives data center managers better server

utilization while reducing cost, power, and cable complexity.

Storage Acceleration

A consolidated compute and storage network achieves significant cost-perfor-

mance advantages over multi-fabric networks. Standard block and

file access protocols can leverage InfiniBand RDMA for high-performance stor-

age access.

3 Hardware Installation

3.1 System Requirements

3.1.1 Hardware

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

3.1.2 Operating Systems/Distributions

Please refer to Section 1.3, “Operating Systems/Distributions,” on page 16.

3.1.3 Software Stacks

Mellanox OpenFabric software package - MLNX_OFED for Linux, WinOF for Windows and

ESX 5.1 for VMware. See

Chapter 4, “Driver Installation”.

3.2 Safety Precautions

1. Remove any metallic objects from your hands and wrists.

2. Make sure to use only insulated tools.

3. Verify that the system is powered off and is unplugged.

4. It is strongly recommended to use an ESD strap or other antistatic devices.

3.3 Pre-installation Checklist

1. Verify that your system meets the hardware and software requirements stated above.

2. Shut down your system if active.

3. After shutting down the system, turn off power and unplug the cord.

4. Remove the card from its package. Please note that the card must be placed on an antistatic

surface.

5. Check the card for visible signs of damage. Do not attempt to install the card if damaged.

3.4 Bracket Installation Instructions

The card is usually shipped with a tall bracket installed. If this form factor is suitable for your

requirements, you can skip the remainder of this section and move to

Section 3.5, “Card Installation

Instructions,” on page 22

. If you need to replace it with the short bracket that is included in the

shipping box, please follow the instructions in this section.

To replace the bracket you will need the following parts:

• The new bracket of the proper height

• One new gasket

The adapter is being installed in a system that operates with voltages that can be lethal.

Before opening the case of the system, observe the following precautions to avoid

injury and prevent damage to system components.

• The 2 screws saved from the removal of the bracket

• The 2 fiber washers saved from the removal of the bracket

3.4.1 Removing the Existing Bracket

Figure 2: Bracket Screws

1. Remove the two screws holding the bracket in place. The bracket comes loose from the card.

2. Save the two screws and the two fiber washers.

3.4.2 Installing the New Bracket

3.4.2.1 Gasket Installation

Note: The following instructions relate to the installation of the gasket for adapter cards that are

not shipped with a gasket already installed. Mellanox Technologies now provides all ConnectX-

3 adapter cards with the gasket already installed unto the bracket.

Note: Due to risk of damaging the EMI gasket, it is not recommended to replace the bracket

more than three times.

1. Remove the paper to expose the adhesive on the gasket.

2. Place the gasket onto the new bracket. Make sure to correctly align the gasket with the hole in

the bracket.

3. If the old gaskets are still on the card, remove them before installing the new bracket.

Be careful not to put stress on the LEDs.
