Virtual Fabric capability allows for the
carving up of a physical NIC into multiple
virtual NICs
The IBM® RackSwitch™ G8124E is a 10 Gigabit Ethernet switch
specifically designed for the data center, providing a virtualized,
cooler and easier network solution. The G8124E offers twenty-four
10 Gigabit Ethernet ports in a high-density, 1U footprint. Designed with
top performance in mind, the RackSwitch G8124E provides line-rate,
high-bandwidth switching, filtering and traffic queuing without delaying
data and large data-center grade buffers to keep traffic moving.
The G8124E is virtualized—providing rack-level virtualization of
networking interfaces. VMready software enables movement of virtual
machines—providing matching movement of VLAN assignments,
ACLs and other networking and security settings. VMready works
with all leading VM providers, such as VMware, KVM, Citrix, Xen,
IBM PowerVM® and Microsoft Hyper-V®. The G8124E also supports
Virtual Fabric, which allows for the carving up of a physical NIC into
2 - 8 virtual NICs (vNICs) and creates a virtual pipe between the adapter
and the switch (using the IBM Networking® OS) for improved performance,
availability and security, while reducing cost and complexity.
The G8124E is cooler—implementing server-like directional cooling to
maximize data center layout and provisioning. Its superior airf low design
complements the hot-aisle and cold-aisle data center cooling model.
G8124E models come in either rear-to-front or front-to-rear airflow
models, allowing customers to design their data center based on their
hot- and cold-aisle implementation.

Data Sheet
IBM Systems and Technology
The G8124E is easier—with server
-oriented provisioning via
point-and-click management interfaces. Its industry standard
CLI, along with seamless interoperability, simplifies configura
-
tion for those familiar with Cisco environments.
The low latency offered by the G8124E makes it ideal for
latency-sensitive applications, such as high-performance
computing clusters and financial applications. The G8124E also
supports the newest protocols, including Converged Enhanced
Ethernet (CEE) and Data Center Bridging for support of
Fibre Channel over Ethernet (FCoE) and can be leveraged for
NAS or iSCSI.

Power
The AC-powered G8124E has dual load-sharing internal power modules, 50 - 60 Hz, 100 - 240 V AC auto-switching
per module.
The DC-powered G8124E has dual load-sharing internal -48 V DC power supplies, input voltage ranging from
42 V dc to 60 V dc per module.
The nominal power for AC or DC G8124E models ranges from 115 W to 168 W depending upon the speed of the port
(1 Gb/10 Gb), type of transceivers (SR or DAC) and number of active ports.
