Lenovo 44W4404 BladeCenter 1-10Gb Uplink Ethernet Switch Module

Product Guide (withdrawn product)

The BladeCenter 1/10Gb Uplink Ethernet Switch Module is a switch option that enables administrators to offer full Layer 2 and 3 switching and routing capability with combined 1 Gb and 10 Gb uplinks in a BladeCenter chassis. Such consolidation simplifies the data center infrastructure and helps reduce the number of discrete devices, management consoles, and management systems. In addition, the nextgeneration switch module hardware can support IPv6 Layer 3 frame forwarding protocols by using a future firmware upgrade.

This Ethernet Switch Module delivers port flexibility, efficient traffic management, increased uplink bandwidth, and strong Ethernet switching price/performance. Figure 1 shows the switch module.

Figure 1. BladeCenter 1/10Gb Uplink Ethernet Switch Module

Did you know?
The switch module’s six 1 Gb RJ45 links can be seamlessly deployed in existing Gigabit networks, while its three 10 Gb small form-factor pluggable plus (SFP+) ports provide an easy migration path to 10 Gb networks. The switch also support all nine uplinks being active at the same time, which can also allow for a simply migration without downtime. All nine uplink ports provide line- rate performance with zero packet drop.
VMready allows the switch to dynamically configure itself to coexist with all leading virtual machine providers such as VMware, Microsoft, Citrix XenServer, PowerVM, and Red Hat KVM.

Benefits
The BladeCenter 1/10Gb Uplink Ethernet Switch Module offers the following benefits:

All 1 Gb and 10 Gb uplink ports can be active at the same time.
The switch consumes only 40 Watts, which is ideal for clients with power limitations or for those who simply want to reduce operating cost and be more environmentally friendly.
It has a large L2 forwarding table (16K), which allows the switch to accommodate a larger flat network with minimum aging activity.
Advanced L3 functions, such as OSPF and BGP, allow the switch to integrate seamlessly into a large routed network environment.
L3 functions allow the switch to segregate traffic into segments to improve latency and security within each segment of the network.

Popular configurations
This section shows how the BladeCenter 1/10Gb Uplink Ethernet Switch Module can be used in configurations.

Basic two-port configuration
Figure 2 shows basic use of the BladeCenter Ethernet Switch Modules to route the two-port Ethernet controller that is integrated onto the blade server. Two Ethernet Switch Modules are installed in bay 1 and bay 2 of the BladeCenter chassis. The connections between the controller and the switch modules are internal to the chassis. No cabling is needed.

---|---|---|---
1| Varies| BladeCenter HS23 or other supported servers| 1 to 14
2| None| 1 Gb Ethernet controller on the system board of the server| 1 per server
3| Varies| Any BladeCenter server (see Table 2)| 1
4| 44W4404| BladeCenter 1/10Gb Uplink Ethernet Switch Module| 2

Four-port configuration

Figure 3 shows the use of BladeCenter Ethernet Switch Modules to route four Ethernet ports from each server: the two integrated ports plus two ports supplied by a compatible CFFv or CIOv expansion card. Four Ethernet Switch Modules are installed in bay 1, bay 2, bay 3, and bay 4 of the BladeCenter chassis. All connections between the controller and card and the switch modules are internal to the chassis. No cabling is needed.

The expansion card can be installed in servers in the BladeCenter S (8886). However, by doing so, you lose the ability to connect to the BladeCenter S Disk Storage Modules (DSMs). The Ethernet expansion card go in the place of the SAS expansion card that is needed to connect to the DSMs. This might be appropriate for clients that wants to use external iSCSI storage or need more than four Ethernet ports per blade. If you are simply looking for redundant Ethernet switches or four Ethernet ports per blade consider using the 2/4 Port Ethernet Expansion Card (CFFh), part number 44W4479.

Maximum configuration: Eight Ethernet ports per server

Since BladeCenter servers support a CFFh expansion card plus either a CFFv or CIOv card (depending on the model of the server), you can install up to eight BladeCenter 1/10Gb Uplink Ethernet Switch Modules in a BladeCenter H chassis or BladeCenter HT. Figure 4 shows this eight-port solution. All connections between the cards and the switch modules are internal to the chassis. No cabling is needed.

Connectors and LEDs

Figure 5 shows the front panel of the BladeCenter 1/10Gb Uplink Ethernet Switch Module.

Lenovo 44W4404 BladeCenter 1-10Gb Uplink Ethernet Switch
Module-4

The front panel contains the following components:

LEDs that display the status of the switch module and the network. These LEDs are OK, which indicates that the switch module has passed the power-on self-test (POST) with no critical faults and is operational, and switch module error, which indicates that the switch module has failed the POST or detected an operational fault.
One USB RS-232 console port that provides an additional means to install software and configure the switch module. This USB-style connector enables connection of a special serial cable that is supplied with the switch module.
Six external 1000BASE-T Ethernet ports for 10/100/1000 Mbps connections to external Ethernet devices.
Three external SFP+ port connectors to attach SFP+ modules for 1000 Mbps connections to external Ethernet devices.
An Ethernet link OK LED and an Ethernet Tx/Rx LED for each external port on the switch module.
