Product Overview
The Cisco Nexus® 7000 Series Switches are the foundation of the Cisco® Unified Fabric solution. 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 the latest extension to the Cisco Nexus 7000 Series modular switches. With more than 83 terabits per second (Tbps) of overall switching capacity, the Cisco Nexus 7700 Switches delivers the highest-capacity 10, 40, and 100 Gigabit Ethernet ports in the industry, with 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 Fabric-2 modules (Figures 1, 2 and 3) for the Cisco Nexus 7700 Series switches are separate fabric modules that provide parallel fabric channels to each I/O and supervisor module slot. Up to six simultaneously active fabric modules work together, delivering up to 1.32 Tbps per slot. Through the parallel forwarding architecture, a system capacity of more than 42 Tbps is achieved with the six fabric modules. The fabric module provides the central switching element for fully distributed forwarding on the I/O modules.
Features and Benefits
Switch fabric scalability is made possible through the support up to six concurrently active fabric modules for increased performance as your needs grow. All fabric modules connect to all module slots. The addition of each fabric module increases the bandwidth to all module slots up to the system limit of six fabric modules. The architecture supports lossless fabric failover, with the remaining fabric modules load balancing the bandwidth to all the I/O module slots, helping ensure graceful removal and insertion.
The combination of the Cisco Nexus 7700 fabric module, the supervisor and I/O modules supports the virtual output queue (VOQ) feature and credit-based arbitration to the crossbar switch to increase the performance and efficiency of the distributed forwarding system. VOQ and credit-based arbitration facilitate fair sharing of resources when a speed mismatch or contention for an uplink interface exists. The fabric architecture also supports Fiber Channel over Ethernet (FCoE) capabilities. Table 1 summarizes the features and benefits of the Cisco Nexus 7700 Fabric-2 modules.
Table 1. Features and Benefits
Feature |
Benefit |
High availability and redundancy |
The fabrics support multilevel redundancy, in which all available fabrics are active, and provide redundancy for all other fabric modules. All I/O module slots receive a fair share of the total fabric bandwidth, helping ensure lossless forwarding in the event of failover. |
Scalable fabric |
The combined fabric modules deliver 24 channels per I/O module and 12 channels per supervisor module, for a scalable capacity of more than 42 Tbps for forwarding performance, which can provide up to 768 x 1 and 10 Gigabit Ethernet, 384 x 40 Gigabit Ethernet, and 192 x 100 Gigabit Ethernet nonblocking ports. |
Non-disruptive addition and removal of fabric modules |
The switch capacity can scale as more fabric modules are added to the system, with transparent upgrades for continuous operations. |
Arbitrated crossbar for unicast |
Class-of-service-aware forwarding is delivered in a fully distributed forwarding system that allows fair scheduling in the event of congestion as well as lossless Ethernet capabilities for FCoE requirements. |
VOQ |
In conjunction with the supervisor module, VOQ provides a quality-of-service (QoS)-aware lossless fabric, avoiding the problems associated with head-of-line blocking. |
Multistage crossbar fabric |
System forwarding performance is enhanced by a combination of local fabric switching between ports on the same module and centralized forwarding through the fabric for ports on different modules. |
Super-framing and frame segmentation |
Crossbar efficiency is optimized by the use of super-framing and frame segmentation to provide deterministic latency and throughput. |
ID LED |
Using the beacon feature, the administrator can clearly identify the chassis and fabric module. |
