APPLICATIONS
These 10 Gigabit Ethernet interface modules are suitable for distribution, core, and data center traffic aggregation, or for interbuilding, points of presence (POPs), WAN edge, and MAN connections. Examples of these applications include data center campus connectivity applications, storage networking applications, and GRID computing applications.
Data Center Campus Connectivity Applications
Productivity and business continuity are top concerns of companies today. Applications like e-learning and video broadcasting help improve corporate communications and information sharing anytime, anywhere. Daily desktop backups can be scheduled over the corporate network to ensure that critical information is not lost when computer hard drives fail. With improved video cameras and picture cameras, digital files are becoming larger and larger. Having a 10 Gigabit Ethernet data center connectivity prepares the network for e-learning, video broadcasting, and wide-scale desktop backups applications (Figure 2).
Figure 2. Applications: Data Center Campus Connectivity
Storage Networking Applications
Storage networking is another application that demands high-bandwidth connection. The growing number of client-server applications, the vast amount of information on internal Web sites, and the importance of information sharing among teams have expanded the requirements for enterprise storage and the need for consolidated storage. 10 Gigabit Ethernet with Jumbo frame support is ideal for network attached storage (NAS) consolidation. To ensure business continuity, companies are also building mirror sites for their data centers at two separate locations. Data stored at both sites can be synchronized periodically using 10 Gigabit Ethernet or 10 Gigabit EtherChannel connections to provide instant disaster recovery (Figure 3).
Figure 3. Applications: Storage Networking
GRID Computing Applications
GRID Computing-using the network to connect clusters of computers together for parallel processing-is an early adopter of 10 Gigabit Ethernet. National laboratories, research departments in universities, multimedia companies, oil companies, and financial institutions are building supercomputers for research, simulation, computer graphics processing, geographic modeling, and financial analyses respectively. 10 Gigabit Ethernet can be used for aggregation and connection to the supercomputers to provide a fast GRID computing network (Figure 4).

Superior Traffic Management and Queuing Characteristics
Cisco Catalyst 6500 Series 10 Gigabit Ethernet modules support multiple queues per port for quality of service. Each port supports Weighted Random Early Detection (WRED) for congestion avoidance within each queue, and Weighted Round Robin (WRR) for scheduling between queues and a strict priority queue for voice traffic. Additionally, multiple thresholds can be configured to manage differentiated levels of service. Ideal for handling mission-critical, bursty, or low-latency traffic such as enterprise resource planning (ERP) or voice applications, the CEF720-based WS-X6704-10GE enable scaling of network performance and intelligent services.
Cisco EtherChannel Technology Increases Link Resiliency and Provides Scalable Bandwidth Aggregation
Cisco Catalyst 6500 Series modules can aggregate up to eight physical Fast Ethernet, Gigabit Ethernet, or 10 Gigabit Ethernet links into a single virtual link using the Cisco Port Aggregation Protocol (PAgP) or IEEE 802.3ad technology. This capability provides network managers a reliable high-speed solution for the campus network backbone.
Cisco Catalyst 6500 Series modules also support multimodule channeling technology, providing even greater resiliency by creating channels across ports on separate modules in the same chassis. As a result, connectivity is maintained even if one module (and corresponding ports) fails. This capability is ideal for deployments requiring scalable, flexible bandwidth within the network. Additional benefits of Cisco EtherChannel capabilities include automatic recovery and redistribution of loads across remaining links; easing management; and making the technology transparent to network applications.
CISCO CATALYST 6500 SERIES 4-PORT 10 GIGABIT ETHERNET INTERFACE MODULE, CEF720
Designed for distribution to core and data center interconnections in networks, the 4-port CEF720-based 10 Gigabit Ethernet interface modules deliver highly scalable high-performance 10 Gigabit Ethernet forwarding capabilities with optional fully distributed forwarding. The WS-X6704-10GE provides higher system port density at an affordable price, encouraging the migration from Gigabit EtherChannel deployments to 10 Gigabit Ethernet. These modules provide the following operational advantages:
• Centralized Forwarding Architecture-The supervisor's (Cisco Express Forwarding) engine performs all forwarding decisions; optional distributed forwarding is supported as an upgrade
• Forwarding Performance-Forwards up to 30 mpps per system (Cisco Express Forwarding) or when equipped with the optional dCEF daughter card for full local forwarding, can deliver up to 48 mpps sustained throughput per slot with sustained system throughput of up to 400 mpps
Note: When two of four ports (ports 1 and 3, 2 and 4, 2 and 3, or 1 and 4) are used on this interface module, equipped with the distributed forwarding card, nonblocking performance is achieved. When all four ports are active, these ports are up to 98 percent nonblocking.
• Distributed Forwarding Upgrade Option-Increases system throughput by allowing all forwarding decisions to be locally distributed to the DFC-equipped interface module; requires a WS-F6700-DFC3BXL or WS-F6700-DFC3B or WS-F6700-DFC3A and Cisco IOS native mode operation on the Supervisor Engine 720
• Fabric Connection-Connects through dual 20-Gbps serial-channel connections to fabric on the Supervisor Engine 720 (40 Gbps total per slot, for 80 Gbps total per slot full duplex)
• Supervisor Engine-Requires the Supervisor Engine 720
• Slot and Chassis Requirements-Can occupy any slot in Cisco Catalyst 6503-E, 6506, 6506-E, 6509, 6509-E or 6509-NEB-A chassis; requires slots 9 through 13 when used in the Catalyst 6513
• Optics-Supports hot-pluggable XENPAK optical modules (see Table 2 for XENPAKs supported and Table 3 for cables available)
