Interconnect Switch Architecture

The ProLiant BL e-Class C-GbE Interconnect Switch contains the ProLiant BL e-Class Integrated Administrator module and two redundant interconnect switch modules (Switch A and Switch B).
Figure 1-2: ProLiant BL e-Class C-GbE Interconnect Switch architecture
1-4 HP ProLiant BL e-Class C-GbE Interconnect Switch User Guide

Integrated Administrator

The ProLiant BL e-Class Integrated Administrator provides centralized, remote management and monitoring for the ProLiant BL e-Class server blade enclosure, interconnect switch module, and 20 server blades. The Integrated Administrator acts as a combination terminal server and remote power controller, enabling out-of-band, secure, serial console connections to all server blades in the enclosure.
The Integrated Administrator serves as a single access point for administrative functions. It provides remote and local setup, deployment, and administrative support, as well as monitoring and health reporting of server blades, interconnect switch modules, and other components in the enclosure, such as power supplies and fans.

Interconnect Switch Modules

Two interconnect switch modules (Switch A and Switch B) in the interconnect switch provide switch redundancy and redundant paths to the network ports on the server blades.
Each interconnect switch has two GB uplink ports and direct connections to one of the two network interface cards (NICs) (NIC 1 and NIC 2) on each server blade. The interconnect switch reduces as many as forty 10/100 Ethernet ports on the server blade into as few as one (up to four) Gigabit uplink ports on the back of the system.
Introduction

Redundant Crosslinks

The two interconnect switch modules are connected through redundant 100-Mb crosslinks. These two crosslinks provide an aggregate throughput of 200 Mb for traffic between the switch modules.

Redundant Paths to Server Blades

The NICs of each server blade are routed through the enclosure’s centerwall assembly to different switch modules. By default, NIC 1 on each server blade is routed to Switch A and NIC 2 on each server blade is routed to Switch B. This configuration provides redundant paths to each server.
IMPORTANT: On a heavily used system, using a single uplink port for all 40 NICs can cause a traffic bottleneck. For example, if uplink 1 on Switch A is the only uplink used, all traffic to and from NIC 2 on any of the server blades must travel over the crosslinks between Switch A and Switch B. This path to the server blade NICs is intended as a failover route and should not be used as a primary path. For optimum performance, use uplink ports from both switch modules.
HP ProLiant BL e-Class C-GbE Interconnect Switch User Guide 1-5
Introduction

Supported Technologies

The ProLiant BL e-Class C-GbE Interconnect Switch supports the following technologies.

Layer 2 Switching

The ProLiant BL e-Class C-GbE Interconnect Switch uses 10/100/1000 Gigabit Layer 2 switching technology. Layer 2 refers to the Data Link layer of the Open Systems Interconnection (OSI) model, which is concerned with moving data packets across a network by enforcing Carrier Sense Multiple Access with Collision Detection (CSMA/CD). This layer performs:
•
Ethernet packet framing
•
MAC addressing
•
Physical medium transmission error detection
•
Medium allocation (collision avoidance)
•
Contention resolution (collision handling)
Layer 2 switch technology allows the interconnect switch to look into data packets and redirect them based on the destination MAC address. This technology reduces traffic congestion on the network, because packets, instead of being transmitted to all ports, are transmitted to the destination port only.

IEEE 802.1Q-Based Virtual Local Area Network

The ProLiant BL e-Class C-GbE Interconnect Switch provides support for a total of 255 IEEE 802.1Q Virtual Local Area Networks (VLANs) (including user configurable and/or dynamic registered), for server grouping and isolation. A VLAN is a network segment configured according to a logical scheme rather than a physical layout. VLANs can be used to combine any collection of LAN segments into an autonomous user group that appears as a single LAN. VLANs also logically segment the physical network into different broadcast domains so that packets are forwarded only between ports within the VLAN. This technology enhances performance by conserving bandwidth and improves security by limiting traffic to specific domains.
IMPORTANT: The greater the number of VLANs, the greater the interconnect switch CPU utilization. For maximum interconnect switch performance, HP recommends that you be judicious when configuring the number of VLANs.

Spanning Tree Protocol

The interconnect switch supports Spanning Tree Protocol (STP), which allows the blocking of links that form loops between switches in a network. When multiple links between switches are detected, a primary link is established. Duplicated links are blocked from use and become standby links. If the primary link fails, the standby link is activated. Refer to Appendix D for more information.
1-6 HP ProLiant BL e-Class C-GbE Interconnect Switch User Guide

Simple Network Management Protocol and Remote Monitoring

Each switch module can be configured and monitored remotely from a Simple Network Management Protocol (SNMP)/Remote Monitoring (RMON) based Network Management Station. The switch modules support industry-standard SNMP Management Information Bases (MIBs), HP Switch MIBs, and RMON groups 1 (statistics), 2 (History), 3 (Alarm), and 9 (Event) for fault detection, configuration, and monitoring of switch functionality. In addition, the interconnect switch supports various environmental traps such as temperature and fan failure traps.
To secure the management interface, the switch administrator can configure community strings with two levels of access. Access can be restricted to a limited number of Management Stations by configuring a list of IP addresses of those stations that can access the interconnect switch. Refer to Appendix E for more information.

Port Mirroring

The interconnect switch allows the user to mirror a port to another port for network monitoring and troubleshooting purposes. This technology offers a way for network packet analyzers to view the traffic moving through the switch modules by providing a copy of the traffic that is currently being passed through any other port. The packets are normally sent to a network packet analyzer or other monitoring device attached to the mirror port.
Introduction

Port Trunking and Load Balancing

The interconnect switch port trunking feature allows several ports to be grouped together and act as a single logical link called a trunk. This feature provides a bandwidth that is a multiple of a single link’s bandwidth. It also improves reliability since a configurable type of load balancing is automatically applied to the ports in the trunked group. A link failure within the group causes the network traffic to be directed to the remaining links in the group.

Trivial File Transfer Protocol Support

The Trivial File Transfer Protocol (TFTP) service feature allows the interconnect switch firmware to be upgraded by downloading a new firmware file from a TFTP server to the switch modules. A configuration file can also be loaded into a switch module from a TFTP server, configuration settings can be saved to the TFTP server, and a history log can be uploaded from the switch module to the TFTP server.

Store and Forward Switching Scheme

The interconnect switch provides a store and forward switching scheme that allows each packet to be buffered (stored) before it is forwarded to its destination. While this method creates latency, it improves reliability in a heavily used interconnect switch. Packets that cannot be forwarded are saved immediately, rather than dropped, and packets behind it are less likely to be dropped in periods of heavy usage.
HP ProLiant BL e-Class C-GbE Interconnect Switch User Guide 1-7
Introduction

IEEE 802.1p-Based Class of Service for Packet Prioritization

Class of Service (CoS) for packet prioritization allows switch administrators to set priority levels on the interconnect switch for forwarding packets based on the priority setting information in the packets. The interconnect switch supports four classes of traffic (buffers or queues) for implementing priority. The interconnect switch allows administrators to map eight priority levels to four classes. Traffic from a specific server port can be given priority over packets from other devices according to this range of priority levels. For example, with multiple packets in a buffer, the packet with the highest priority would be forwarded first, regardless of when it was received.

Internet Group Management Protocol Snooping

Internet Group Management Protocol (IGMP) snooping, when enabled and configured properly, manages multicast traffic in a switch module by allowing directed switching of the IP multicast traffic. The interconnect switch can use IGMP snooping to configure switch module ports dynamically, so that IP multicast traffic is forwarded only to those ports associated with IP multicast hosts.
IGMP snooping allows the switch module to recognize IGMP queries and reports sent between network stations or devices and an IGMP host that belongs to a specific multicast group. When enabled for IGMP snooping, the switch module can open or close a port to a specific device based on IGMP messages passing through the module. This feature further limits unnecessary broadcasts. The GbE Interconnect Switch can be configured to use either IGMP version 1 or version 2 when making queries

Dynamic Host Configuration Protocol or Bootstrap Protocol

A switch module can be configured to obtain an IP address from a Dynamic Host Configuration Protocol (DHCP) or Bootstrap Protocol (BOOTP) server during the boot process. By default, the interconnect switch is configured for DHCP. The IP settings can be manually configured through the console interface. The IP settings are also configurable from other interfaces, such as the Web, but since the connection is based on an IP address for these interfaces, users have to reconnect with the newly assigned IP address.
1-8 HP ProLiant BL e-Class C-GbE Interconnect Switch User Guide

Simple Network Time Protocol

The interconnect switch can maintain the current date and time. This information displays on the management interfaces and is used to record the date and time of switch events. Current date and time information can be manually set on the interconnect swithc or can be obtained through Simple Network Time Protocol (SNTP). SNTP allows the interconnect switch to send a request to a primary or secondary SNTP server in each polling period asking for the Greenwich Mean Time (GMT). If the primary SNTP server is not available, the request is sent to a secondary SNTP server.

User Account Management

For increased security, separate user accounts can be set up with various levels of permission.

External Components

This section describes the external panel and LED indicators of the ProLiant BL e-Class C-GbE Interconnect Switch.
Introduction

External Panel

The external panel of each interconnect switch has four RJ-45 connectors with Gigabit Ethernet uplink connectivity for network cabling.

Planning the Interconnect Switch Configuration

Before you configure the switch modules, HP recommends that you plan the configuration. As you plan, keep in mind the default settings, security issues and privileges, and whether you want to configure each switch module manually or configure multiple switch modules at the same time.

Default Settings

IMPORTANT: Refer to Appendix C for detailed default configuration settings.
The interconnect switch ships with a default configuration with all ports (of both Switch A and Switch B) enabled and assigned the same virtual LAN (VLAN). In addition, the Integrated Administrator management connector (connected to internal port 23 of Switch A) is assigned to the same default VLAN.
This default configuration simplifies your initial setup by allowing you to use a single uplink cable (from any external Ethernet connector) to connect the server blade enclosure and its server blades to your network. Keep in mind that your environment may require other configurations.
When planning the configuration, consider the defaults for the following parameters:
•
Switch IP settings
•
Virtual Local Area Network (VLAN) and GARP VLAN Registration Protocol (GVRP) settings
•
Spanning Tree Protocol (STP) settings
•
Port names and types
•
Port trunking settings
•
Class of Service (CoS) settings
•
Interswitch X-connect port settings
•
Simple Network Management Protocol (SNMP)/Remote Monitoring (RMON) settings
•
User name and password settings
•
Default access to various management interfaces
•
Internet Group Management Protocol (IGMP) Snooping settings
•
Simple Network Time Protocol (SNTP) settings

Interconnect Switch Security

When planning the configuration for a switch module, secure access to the management interface by:
•
Creating users with various access levels to the local console, remote Telnet, and Web interface. Refer to Table 2-1 for the three levels of user access privileges.
•
Enabling or disabling access to various management interfaces to fit the security policy.
•
Changing default SNMP/RMON community strings for read-only and read-write access.
Root, User+, and User Privileges
There are three levels of user privileges: Root, User+, and User. Some menu selections available to users with Root privileges may not be available to those with User+ and User privileges.
The following table summarizes user privileges.
Table 2-1: User Privileges
Setting up and Installing the Interconnect Switch
Privilege Root User+ User

Network Monitoring Yes Read-only Read-only
Community Strings and Trap Stations Yes Read-only Read-only
Update Firmware and Configuration Files Yes No No
System Utilities Yes Ping-only Ping-only
Factory Reset Yes No No
Reboot Switch Yes Yes No
Add/Update/Delete User Accounts Yes No No
View User Accounts Yes No No

Manually Configuring a Switch Module

A switch module can be configured manually using a local console interface, a remote Telnet console interface, a Web interface, or an SNMP interface. Refer to the management interface reference guides for information on how to configure the switch modules.
After a switch module is configured, you can back up the configuration as a binary file to a TFTP server. The backup configuration file can then be downloaded from the TFTP server to restore the switch module back to the original configuration, under one of the following conditions:
• • The switch module configuration gets corrupted during operation.
The switch module needs to be replaced due to hardware failure.

Setting up and Installing the Interconnect Switch

Configuring Multiple Switch Modules

You can configure multiple switch modules by using scripted Command Line Interface (CLI) commands through Telnet or by downloading a configuration file using a TFTP server.
Using Scripted CLI Commands through Telnet
The CLI, provided with the interconnect switch, allows you to execute customized configuration scripts on multiple switch modules. A configuration script can be tailored to one of the multiple switch modules, and then that configuration can be deployed to other switch modules from a central deployment sever.
Using a Configuration File
If you plan for the base configuration of multiple switch modules in your network to be the same, you can manually configure one switch module, upload the configuration to a TFTP server, and use that configuration file as a base configuration template. This base configuration file can then be downloaded to multiple switch modules.
Small configuration changes can be pushed out to multiple switch modules by creating a configuration file with just the configuration items desired. The configuration file can be downloaded to each switch module needing the change. Refer to Appendix H, XML Configuration, for additional information regarding the XML configuration file.
Switch module IP addresses are acquired by default using DHCP, therefore, each module has a unique IP address. Each switch module can be remotely accessed from a central deployment server and an individual switch module configuration can be downloaded to meet specific network requirements. Refer to the management interface reference guides for more information on using a TFTP server to upload and download configuration files.

Cabling the Interconnect Tray

After installing the interconnect switch hardware and planning the configuration, cable the interconnect tray to your network.
CAUTION: In order to avoid damaging the server blade enclosure, observe the following guidelines when cabling:
• Connect the AC power cords last.
• Be sure to connect both AC power cords for redundancy and proper cooling.
• Bundle all cables and route them to the edge of the rack for proper cooling and airflow.
2-10 HP ProLiant BL e-Class C-GbE Interconnect Switch User Guide
Setting up and Installing the Interconnect Switch
To cable the interconnect tray:
Figure 2-13: Connecting the Integrated Administrator module
1. Connect the Integrated Administrator module to your network by using the management
connector (10/100 Ethernet).
Figure 2-14: Connecting the network cables
2. Install the network cables. By default, each server blade has PXE enabled on Ethernet
Port 1. Since the Ethernet Port 1 of every server blade physically routes through Switch A, HP recommends that either Port 25 or 26 of Switch A be used for PXE functions.

Setting up and Installing the Interconnect Switch
Figure 2-15: Connecting the power cables
3. Install the power cords. The server blade enclosure and interconnect switch power up as soon as power is applied to the enclosure.
CAUTION: Because the server blade enclosure uses both power supplies for power redundancy and proper cooling, be sure that both power cords are connected at all times.
Figure 2-16: Routing the cables
4. Bundle the network and power cables together and route them to the outer edge of the rack.
