Nexus 7700 – Supervisor 3 Enhanced
Part Number: N77-SUP3E
The Cisco Nexus® 7000 Series Switches are designed to meet the requirements of mission-critical data centers. These switches deliver exceptional availability, outstanding scalability, and the proven and comprehensive Cisco® NX-OS Software data center switching feature set.
The Cisco Nexus 7700 Switches are an extension of the Cisco Nexus 7000 Series modular switches. With more than 83 Terabits per second (Tbps) of overall switching capacity, the Cisco Nexus 7700 Switches support up to 768 native 10-Gbps ports, 384 40-Gbps ports, or 192 100-Gbps ports. This high system capacity is designed to meet the scalability requirements of the largest cloud environments.
The Cisco Nexus 7700 switches have operational and feature consistency with the existing Cisco Nexus 7000 Series Switches, using common system architecture, the same Application-Specific Integrated Circuit (ASIC) technology, and the same proven Cisco NX-OS Software releases.
The Cisco Nexus 7700 Supervisor 3E (Supervisor 3 Enhanced) Module (see Figure 1) scales the control-plane and data-plane services for the Cisco Nexus 7700 Switches in scalable data center networks. The enhanced supervisor module delivers control-plane and management functions. The supervisor controls the Layer 2 and 3 services, redundancy capabilities, configuration management, status monitoring, power and environmental management, and more. It provides centralized arbitration to the system fabric for all line cards.
The fully distributed forwarding architecture allows the supervisor to support transparent upgrades to I/O and fabric modules with greater forwarding capacity. Two supervisors are required for a fully redundant system, with one supervisor module running as the active device and the other in hot-standby mode, providing exceptional high-availability features such as stateful switchover and In-Service Software Upgrade (ISSU) on mission-critical data center–class products.
