Mellanox Technologies

Chapter 1. Introduction

This chapter introduces the Mellanox InfiniBand-to-10 GbE Gateway (sRB-20210G).

1.1 Overview

The sRB-20210G module (see Figure 1-1 and Figure 1-2) is an InfiniBand-to-10 GbE gateway

module, designed as a plug-in unit for installation in the Mellanox ISR 2004/2012 Grid

Director.

The sRB-20210G module enables multiple virtual networks to span across InfiniBand and

Ethernet-based networks providing network-agnostic enterprise-class connectivity. With this

solution, InfiniBand can be used to accelerate applications without the need to replace

Ethernet-based services and devices while allowing the provision of multiple virtual Ethernet

and storage networks on from same director class switch.

IMPORTANT:

The sRB-20210G module is used as a bridge in the system. It does not run on several

subnets. However, it can be used to interface several subnets using partitions. For more

information, refer to Chapter 13, Partitioning.

1.2 Physical Description

1.2.1 Plug-in Module

1.3 Features

1.3.1 Basic Features

The basic functional features of the sRB-20210G module include:

 High performance InfiniBand-to-10 GbE connectivity using Mellanox-developed silicon

 Extremely low latency using cut-thru architecture (under two [2] microseconds)

 IBTA 1.1 compliant

 Standard IPoIB support

 VLAN support according to 802.1q (up to 64 IB partitions; see New in Version 2.0)

 IP Multicast support – up to 1024 multicast groups

 Layer 2/3/4, traffic filtering, and classification

 Link aggregation, load sharing, and High Availability

 CLI and GUI management via the Mellanox Fabric Manager (VFM) and the Mellanox

Device Manager (VDM).

1.3.2 New in Version 2.0

Version 2.0 includes the following improvements and enhancements:

 Support for different MTU rates on the Ethernet and IB side. This allows the gateway to

work in a Jumbo frame environment on the Ethernet side. It also reduces the burden of

decreasing the default MTU of all IB hosts in the fabric from 2 Kbytes to 1.5 Kbytes.

 A loop prevention mechanism has been added for cases when multiple gateways are

deployed in a specific application, so that the user would be able to configure them

without creating loops on the Ethernet network, while preserving the high-availability

requirements.

 Support for up to 64 partitions/VLANs

 Support for up to 3,000 multicast groups

 Enhanced monitoring capabilities.

1.4 Functional Description

1.4.1 High Performance InfiniBand-to-GbE Connectivity

The sRB-20210G core capabilities rely on the Mellanox in-house developed silicon used for

forwarding traffic between InfiniBand and Ethernet infrastructures. This custom silicon

enables the Mellanox sRB-20210G to achieve wire-speed protocol processing with minimal

latency, while transparently providing upper-layer traffic classification capabilities. In

addition, multiple 10 GbE ports can be aggregated to scale connectivity and meet various

application requirements.

1.4.2 Comprehensive Management

The rich functionality provided by the Mellanox sRB-20210G is fully integrated into

GridVision™ Grid Interconnect Management Software that is embedded in Mellanox

InfiniBand switches and gateways.

GridVision is an easy-to-use management suite that provides access through a Web-based

GUI, a command line interface (CLI) and SNMP.

Out-of-band management includes InfiniBand, Ethernet and EIA/TIA-232 connections. The

Mellanox sRB-20210G Gateway management is also integrated with leading third party grid

and on-demand management platforms.

1.4.3 sRB-20210G Architecture

 All data traffic is handled by the sRB-20210G hardware (Silicon) to achieve the highest

possible throughput, with the lowest possible latency.

 Management traffic is handled in software by the CPU.

1.4.4 Supported Protocols

The sRB-20210G supports the following protocols:

 10 Gigabit Ethernet over fiber - IEEE 802.3ae - 10GBASE-SR and 10GBASE-LR.

 10 Gigabit Ethernet over twin-axial cable – IEEE 820.3ak – 10GBASE-CX4

 InfiniBand 1.1 compliant

 IETF RFC 4391 Transmission of IP over InfiniBand (IPoIB)

 IETF RFC 4392 IP over InfiniBand (IPoIB) Architecture

 SNMP v2c: IETF-RFC190x

 Java 1.6 for the GUI.

IPoIB (IP-over-InfiniBand) is a protocol for encapsulating data requests and responses over

InfiniBand. The sRB-20210G uses IP over InfiniBand (IPoIB) protocols in order to provide IP

link between Ethernet network and InfiniBand based network.

The tunneling functionality is achieved by Layer II address translation of an InfiniBand

address to an Ethernet address (MAC) and vice versa.

1.4.5 sRB-20210G Application Diagram

Figure 1-4 shows an example of an IPoIB network.

Figure 1-4. IPoIB Network Response/Request Routing

The sRB-20210G provides transparent bridging of Ethernet traffic to servers on the InfiniBand

fabric and vice versa, as if they were directly attached to the clients over a local network. This

network behavior resembles a bridge methodology.

1.4.6 Traffic Flow Management Overview

The Traffic Flow Management (TFM) feature allows a network administrator to determine

rules for handling IP packets arriving at the sRB-20210G, based on their source or destination

IP address and ports. The administrator can define services and rules to control how the

sRB-20210G processes these packets. This processing includes:

 Forwarding – the packet is forwarded to a destination host either on the Ethernet side

or the InfiniBand side

 Drop – the packet is discarded.

The CLI

add

and

remove

CLI commands are used for managing the packet handling rules in

the sRB-20210G. The user can define rules or use the default rules. If no new rule was added

or if there was no change to the default rules, the packets are handled by a default method. For

further details, refer to the Traffic Flow Manager (TFM), Chapter 8.

Chapter 2. Initial Configuration

This chapter provides instructions on how to perform the basic initial configuration settings for

the sRB-20210G. These steps are typically performed when installing a new device.

2.1 Prerequisite Installation Tasks

IMPORTANT:

Before configuring the Mellanox sRB-20210G for the first time, make sure you have

completed the hardware installation according to the relevant Mellanox Installation Manual.

The sRB-20210G is managed through the Switch chassis management, via either inband

(through the InfiniBand interface) or out-of-band (through the Ethernet interface)

connection. For more information on Inband/out-of-band management, refer to the switch

(ISR 2xxx) user manual.

2.2 Configuring the sRB-20210G Gateway in the ISR 2XXX

NOTES:

Do not physically connect any of the sRB-20210G GbE ports to the same physical network

as the switch’s Ethernet management port. In order to prevent broadcast packet loops, the

switch’s Ethernet management port must be physically-separated from the GbE network

and InfiniBand fabric.

The management interface of the sRB-20120G (smb-mng) must be configured with a

unique IP address on the same network with the Ethernet/InfiniBand management

interface of the switch. Refer to the GridVision Integrated Documentation Suite (First-Time

Configuration) for further details.

2.2.1 Managing the Unit over Fast Ethernet (Out-of-Band) or InfiniBand

(Inband)

When the system is configured to manage a chassis containing an sRB-20210G, and the Fast

Ethernet is the selected management interface in the ISR 2XXX Grid Director, the sMB

automatically enters into Proxy-ARP mode. This allows the connection between the manager

that resides on the ETH network and the sRB-20210G residing on the InfiniBand network.

IMPORTANT:

 Make sure to configure the sRB-20210G management (smb-mng) interface on the

same subnet that was defined for the switch management (Fast Ethernet) interface.

 The management interface of the sRB-20120G (smb-mng) must be configured with a

unique IP address on the same network with the Ethernet/InfiniBand management

interface of the switch. Refer to the GridVision Integrated Documentation Suite

(First-Time Configuration) for further details.

Step 1

Configure the Switch sMB Fast Ethernet interface (IP address, subnet mask), as described in

the Switch User Manual (First-Time Configuration Section).

Step 2

Configure the Switch InfiniBand interface to the same values of the Fast Ethernet interface,

the same IP address and same subnet mask, as described in the Switch User Manual

(First-Time Configuration Section).

Step 3

Make sure that the IP address of each I/O Gateway module is set on the same subnet

defined for the Fast Ethernet interface.

Step 4

Configure the gateways as detailed in the following procedure.

NOTE:

If you are setting the management through fast Eth

(inband) then you must set the default gateway

address to the smb-mng management interface.

This command sets the default gateway as shown in

the example below. This will add the default gateway

to the Route Table.

Set the default gateway of the management as

shown in the following examples. This will add the

default gateway to the Static Route Table.

IMPORTANT:

If you are setting the management through fast

Ethernet interface (out-of-band), then you must set

the default gateway address to the smb-mng

management interface.

If you are setting the management through InfiniBand

(inband), then you must set the default gateway

address to the if0 management interface.

Example (Out-of-band – Ethernet Interface):

10G-Card(config-route)# default-gw set 1

172.30.0.1 smb-mng
