Essentially, The Cisco Nexus 9508 switch is the first modular chassis-based switch in the Cisco Nexus 9500 switches series. The Cisco Nexus 9508 is a modular, 8-slot, 13 RU high, layer 2 and 3 non-blocking Ethernet and Fiber Channel over Ethernet-capable Cisco switch. With more than 30 Tbps of backplane bandwidth, this platform supports 1/10/40 and 100 Gigabit Ethernet interfaces through a comprehensive selection of modular line cards.
Configurable with up to 1152 10G Ethernet ports or 288 40G Ethernet ports, the switch provides sufficient capacity for both access and aggregation layer deployments. The Cisco Nexus 9508 is a modular chassis that supports up to eight-line cards, has two redundant supervisor modules, two redundant system controllers, three fan trays, up to six fabric modules, and up to eight power supplies. All major components are redundant, including the supervisors, the system controllers, the power supplies and the fan trays.
The switch line cards use a mix of merchant and Cisco ASIC provide innovative functionality, low complexity and cost-optimized design. One of examples here is the hardware will support not only VXLAN bridging but also VXLAN routing functionality on the same switch which is very important for modern cloud data centers where customers expect end-to-end visibility and control across their virtual and physical switch infrastructure. Furthermore, the buffer memory is integrated into the forwarding ASICs, avoiding the need for a large number of external memory modules. All transceivers are pluggable to support the highest possible availability for the switch.
The Cisco Nexus 9500 platform is the first switch chassis designed without mid-plane. Line cards and fabric modules connect directly. This design approach provides optimal front-to-back airflow helps the switch operate using less power. Therefore, the typical power consumption per 10 Gigabit Ethernet port is less than 3.5W and the typical power consumption for each 40 Gigabit Ethernet port is less than 14W.
