ExtremeSwitching VDX 8770

Extreme VCS fabric running on the ExtremeSwitching VDX series allow organizations to create data center networks that just work. Together, these technologies provide unmatched automation and resilience in support of the most demanding workloads, such as big data, rich media, and mission-critical applications.

ExtremeSwitching VDX 8770

Scaling Out Extreme VCS fabrics

The ExtremeSwitching VDX 8770 is a highly scalable, low-latency, 1/10/40 Gigabit Ethernet (GbE) modular switch. Designed to easily scale out Extreme VCS fabrics, the ExtremeSwitching VDX 8770 Switch brings new levels of performance to VCS fabric deployments. The ExtremeSwitching VDX 8770 is designed with advanced capabilities, including 100 GbE and hardware-enhanced SDN support, to support data center networking a decade or more into the future.
