IBM RackSwitch G8124E

Highlights

The IBM® RackSwitch G8124E is a 10 Gigabit Ethernet switch specifically designed for the data centre (DC), providing a virtualised, cooler and easier network solution. The G8124E offers twenty-four 10 GbE 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 DC grade buffers to keep traffic moving.

The G8124E is virtualised–providing rack-level virtualisation of networking interfaces. VMready software enables movement of virtual machines (VMs) – providing matching movement of virtual local area network (vLAN) assignments, access control lists (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 maximise DC layout and provisioning. Its superb airflow design complements the hot-aisle and cold-aisle DC cooling model. G8124E models come in either rear-to-front or front-to-rear airflow models, allowing customers to design their DC 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 command line interface (CLI), along with seamless interoperability, simplifies configuration for those familiar with Cisco environments.
