IBM System Networking RackSwitch G8124E

Ultra-low-latency, high-performance 10 Gb top-of-rack switch


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 airflow 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.

The G8124E is easier—with server-oriented provisioning via point-and-click management interfaces. Its industry standard CLI, along with seamless interoperability, simplifies configuration for those familiar with Cisco environments.
