Changing application environments are placing new demands on your IT infrastructure. With application workloads deployed across a mix of virtualized and nonvirtualized server and storage infrastructure, your network must provide constant connectivity, security, and visibility across bare-metal, virtualized, and cloud computing environments. For example:
● Application instances are created dynamically, so provisioning, modification, and removal of application network connectivity also need to be dynamic.
● With business units demanding accelerated application deployments, your IT department needs to provide a shared IT infrastructure that addresses time-to-market needs and an increased Return On Investment (ROI).
● When you deploy a mix of custom, open-source, and off-the-shelf commercial applications, your IT department must manage security and Quality of Service (QoS) for environments that support multitenancy.
● With applications transitioning to a less monolithic, scale-out, multinode model, your IT infrastructure must scale with the speed of business and provide support for 100 Megabit Ethernet connectivity and 1, 10, 25, 40, 50, and 100 Gigabit Ethernet connectivity.
The Cisco Nexus® 9000 Series Switches include modular and fixed-port switches that overcome these challenges with Cloudscale Technology enabled infrastructure that is flexible, agile, and programmable.
The Cisco Nexus 9500 platform, part of the Cisco Nexus 9000 Series (Figure 1), offers three modular options: the Cisco Nexus 9504 Switch with 4 slots, the Cisco Nexus 9508 Switch with 8 slots, and the Cisco Nexus 9516 Switch with 16 slots. All three switches use the same supervisor, system controller, power supplies, and line cards. The Cisco Nexus 9500 platform consists of Layer 2 and 3 nonblocking Ethernet switches with backplane bandwidth of up to 115.2 Terabits per second (Tbps). The Cisco Nexus 9504, 9508, and 9516 Switches support 1, 10, 25, 40, 50, and 100 Gigabit Ethernet interfaces through a comprehensive selection of modular line cards. Configurable with up to 2304 x 10 Gigabit Ethernet ports, 2048 x 25 Gigabit Ethernet ports, 576 x 40 Gigabit Ethernet ports, 1024 x 50 Gigabit Ethernet ports, or 512 x 100 Gigabit Ethernet ports, they provide ample capacity for both access- and aggregation-layer deployments.
