IBM System Networking RackSwitch G8124E
IBM Redbooks Product Guide
The IBM®System Networking RackSwitch™G8124E 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 1G or 10G, this switch is designed for those clients that are leveraging 10G Ethernet
today or have plans to in the future. This is the first Top of Rack 10Gb switch for IBM System x®
designed to support IBM 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 10G adapter, in
addition to reducing the number of cables and upstream switch ports required. Virtual Fabric allows
clients to carve up a dual-port 10G 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. Figure 1 shows the IBM
System Networking RackSwitch G8124E.

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.
IBM 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.
IBM is a leader in helping clients reduce the complexity of managing VMs and VM migration with
their IBM VMready®product, which makes the network VM aware.

With the flexibility of the G8124E switch, clients can take advantage of the technologies that they
require for multiple environments. For 10 Gb uplinks, they have a choice of either SFP+ transceivers
(SR or LR) for longer distances or more cost-effective and lower-power-consuming options such as
SFP+ direct-attached cables (DAC or Twinax cables), which can be 1 - 8.5 meters in length and are
ideal for connecting chassis together, connecting to a Top of Rack switch, or even connecting to an
adjacent rack.

Benefits
The IBM System Networking RackSwitch G8124E offers the following benefits:
High performance: The 10G Low Latency (as low as 570 nanoseconds) switch provides the best
combination of extremely low latency, non-blocking line-rate switching and ease of management.
Lower power and better cooling : The G8124E uses as little power as two 60 W light bulbs, which
is a fraction of the power consumption of most competitive offerings. Unlike side-cooled switches,
which can cause heat recirculation and reliability concerns, the G8124E rear-to-front cooling
design reduces data center air conditioning costs by having airflow match the servers in the rack.
In addition, variable speed fans assist in automatically reducing power consumption.
Virtual Fabric can help customers address I/O requirements for multiple NICs while also helping
reduce cost and complexity. Virtual Fabric for IBM allows for the carving up of a physical NIC into
multiple virtual NICs (2 - 8 vNICs) and creates a virtual pipe between the adapter and the switch
for improved performance, availability, and security while reducing cost and complexity.
VM aware Networking: VMready software on the switch helps reduce configuration complexity
while significantly improving security levels in virtualized environments. VMready automatically
detects virtual machine movement from one physical server to another, and instantly reconfigures
each VM’s network policies across VLANs to keep the network up and running without interrupting
traffic or impacting performance. VMready works with all leading VM providers such as VMware,
Citrix, Xen, IBM PowerVM
®
, and Microsoft.

IBM System Networking RackSwitch G8124E 6
Layer 3 functionality: The switch includes Layer 3 functionality, which provides security and
performance benefits as inter-VLAN traffic stays within the chassis. This switch also provides the
full range of Layer 3 protocols from static routes for technologies such as Open Shortest Path
First (OSPF) and Border Gateway Protocol (BGP) for enterprise customers.
Seamless Interoperability : IBM switches interoperate seamlessly with other vendors' upstream
switches. For more information, see Tolly Reports: Tolly Functionality and Certification:
RackSwitch G8000 and G8124 and Cisco Catalyst Interoperability Evaluation. For more
information, visit the following website:
http://ibm.co/ZRwiR0
Fault tolerance: These switches learn alternate routes automatically and perform faster
convergence in the unlikely case of a link, switch, or power failure. The switch uses proven
technologies, such as L2 trunk failover, advanced VLAN-based failover, VRRP, HotLink, Uplink
Failure Detection (UFD), IGMP V3 snooping, and OSPF.
Converged fabric: The switch is designed to support CEE/DCB and connectivity to FCoE
gateways. CEE helps enable clients to combine storage, messaging traffic, VoIP, video, and other
data on a common data center Ethernet infrastructure. FCoE helps enable highly efficient block
storage over Ethernet for consolidating server network connectivity. As a result, clients can deploy
a single server interface for multiple data types, which can simplify both deployment and
management of server network connectivity, while maintaining the high availability and
robustness required for storage transactions.
Transparent networking capability : With a simple configuration change to Easy Connect mode,
the RackSwitch G8124E becomes a transparent network device, invisible to the core, eliminating
network administration concerns of Spanning Tree Protocol configuration/interoperability, VLAN
assignments and avoids any possible loops.
By emulating a host NIC to the data center core, it accelerates the provisioning of VMs by
eliminating the need to configure the typical access switch parameters.

Virtual Fabric configuration
IBM Virtual Fabric for IBM System x is built using industry standards and is an ideal solution for
customers that require more than two NICs per server. Over the past couple of years many clients
have seen their I/O requirements per server increase anywhere from four to six to eight, or even more,
NICs per server, especially with the adoption of virtualization. IBM Virtual Fabric allows clients the
ability to use a virtual NIC approach using10G Ethernet technology to help reduce cost and
complexity, and achieve better performance and more flexibility. For example:
Reduce costs: (acquisition and operating) by using fewer adapters, cables, and upstream switch
ports.
Reduce complexity: Fewer items to manage, based on industry standards making thing easier to
manage with the addition of high availability and better security.
Better performance: Significantly more I/O bandwidth per server and lower latency than traditional
1G Ethernet.
Flexibility: The ability to carve up a dual-port 10G adapter into 4 - 8 virtual NICs and create virtual
pipes between the adapter and switch for higher availability and security. Not only can customers
dynamically allocate I/O bandwidth to each virtual NIC, Virtual Fabric also provides the ability to
change those allocations as needed. For example, a customer may have one configuration for
workload during the day and another during the evenings. Virtual Fabric has the ability to make
those changes on the fly without downtime.
