Providing incomparable flexibility for high-performance datacenters. As the bandwidth demands of modern computing and smart device applications continue their exponential growth, data centers must maintain the flexibility necessary to continually enhance the density and reliability of their existing networking environments. The technology most critical to such network flexibility and enhancement consists of dense 40 and 100 Gigabit Ethernet switching devices, among which only a limited number possess the required technological capacity to facilitate the development of both leaf and spine networking tiers. The S9280-64X is one such data center switch allowing for the assembly of high-performance, high-density, fixed-configuration, data center networks offering speed layer 2 and layer 3 features. For data centers evolving from existing 10GE and 40GE to 25GE, 50GE, and 100GE, the S9280-64X provides the seamless transition necessary to maintain and enhance both interface speed and density. The flexibility offered by the S9280-64X is most apparent in its capacity to support speeds including 10GE, 25GE, 40GE, 50GE, and 100GE, a capacity which in turn meets the demands of all manner of applications and east-west traffic loading challenges. Simply put, the S9280-64X is a purpose-built, high-density switch with 64 QSFP28 100GE ports and an overall throughput of up to 12.8Tbps, a latency of under 800ns, and 40MB of buffer. Each QSFP28 port supports flexible configurations between 4 x 10GE, 4 x 25GE, or 2 x 50GE modes for up to 128 ports without limitation.
