RackSwitch G8124E

Lenovo Press Product Guide

The RackSwitch™ G8124E (shown in Figure 1) delivers exceptional performance that is both lossless

and low latency. In addition, the G8124E delivers excellent cost savings as you consider acquisition

costs, energy costs, plus its feature-rich design with when it comes to virtualization, CEE/FCoE, high

availability, and its enterprise class Layer 2 and Layer 3 functionality.

With support for 1 Gb Ethernet or 10 Gb Ethernet, the G8124E switch is designed for those clients that

are leveraging 10 GbE today or have plans to in the future. This is the first top of rack (TOR) 10 GbE

switch designed to support Virtual Fabric, which helps clients significantly reduce cost and complexity

when it comes to the I/O requirements of most virtualization deployments today. Virtual Fabric can help

clients reduce the number of multiple I/O adapters down to a single dual-port 10 GbE adapter, in addition

to reducing the number of cables and upstream switch ports required. Virtual Fabric allows clients to

carve up a dual-port 10 GbE adapter into eight virtual NICs (vNICs) and create dedicated virtual pipes

between the adapter and the switch for optimal performance, plus higher availability and better security.

This functionality provides the ability to dynamically allocate bandwidth per vNIC in increments of 100 Mb,

while being able to adjust over time without downtime.

Did you know?

The G8124E switch is designed to support a number of separate types of configurations from a server or

downstream switches: 1 Gb, 10 Gb, virtual NIC, Converged Enhanced Ethernet (CEE/FCoE), and iSCSI.

This single switch can handle all these workloads and can connect to an upstream 1 Gb or 10 Gb

infrastructure, or both.

The G8124E is designed to support data center bridging (DCB), which is the IEEE's group of protocols

that provide Lossless Ethernet and allows for clients to reduce the costs of implementing FCoE by

leveraging port aggregation before connecting to more costly upstream gateway devices.

The G8124E can be configured in "easy connect" mode to allow for transparent and simple connectivity to

the upstream network, enabling easy connectivity to upstream Cisco, Juniper or other networks without

having to change those networks.

Virtual Fabric helps clients reduce costs and complexity in environments where they need four or more

NICs per server. A perfect example is virtualization, where clients often need as many as eight NICs per

server.

The G8124E can help clients reduce the complexity of managing VMs and VM migration with VMready

feature that makes the network VM-aware.
