Cisco UCS 2304 Fabric Extenders provides up to 160 Gbps of bandwidth to each of the two fabrics in a Cisco UCS 5108 Blade Server Chassis, for up to 320 Gbps of bandwidth using two fabric extenders and only eight cables.Cisco UCS 6300 Series Fabric Interconnects provide 40 Gigabit Ethernet connectivity upstream to access-layer switches and downstream to Cisco UCS servers.Your upgrade concerns are addressed with a new family of 40-Gbps fabric components that can be swapped into existing systems or provisioned with new Cisco UCS instances: The third generation of Cisco Unified Fabric for the Cisco Unified Computing System ™ (Cisco UCS ®) makes the transition to 40 Gigabit Ethernet smooth and cost effective. With traditional infrastructure, each server would need new network interfaces and cabling to top-of-rack switches, and then new fiber from top-of-rack switches to aggregation-layer switches-requiring tasks taking hours of administrator time per server and significant recabling time and expense. Existing servers need to be accommodated, and a plan needs to be in place to support new servers. The problem is how to join servers with a need for 40 Gbps of bandwidth with a 40-Gbps-ready data center network so that the transition can be graceful, with minimal cost and disruption. This approach delivers more consistent latency and greater east-west bandwidth while helping maintain security and Quality of Service (QoS) through policy-based network infrastructure deployment and management. Many organizations are accommodating this shift by adopting the leaf-and-spine network topology provided by Cisco ® Application Centric Networking (Cisco ACI ™). With virtualization now the norm, massive east-west scalability is required, as well as the ability to handle more bandwidth between servers in virtualization clusters. Today, the power of Intel ® Xeon ® processors combined with massive amounts of memory allow servers to saturate 10 Gigabit Ethernet links, increasing the demand for more network bandwidth and for more headroom to absorb spikes in workload demands.ĭata center networks are transitioning to 40 Gigabit Ethernet to accommodate the increased network and storage traffic imposed by an increasing number of application workloads. A decade ago, servers became powerful enough to saturate Gigabit Ethernet interfaces, prompting a move to 10 Gigabit Ethernet. Continuous progress in data center technology is propelling a transition to 40 Gigabit Ethernet.
