Switching and server port speed transitions Upward evolution of the PCIe bandwidth driving higher Ethernet port speeds in the NIC.Upward evolution of switch ASICS enabling greater bandwidth connectivity in the rack. Switching and server port transitions to higher speeds.Let’s look at some of the trends within the data center infrastructure-switch architecture, compute to network PCIe bandwidth evolution and switch to server connectivity speeds and deployment models: To address the bandwidth requirements or potential bottlenecks within the data center, the switching, compute to network bandwidth, and cabling infrastructure needs to evolve both in terms of speed and network placement. In this paper, Cisco and Panduit will describe some of the trends in data center connectivity and the impact this compute-intensive workload have on cabling and network infrastructure design with corresponding deployment guidelines.Īpplications like machine learning or AI are compute intensive and are processed across multiple servers, physical and virtual, all interconnected locally within or across multiple racks requiring bandwidth to be distributed within and across multiple facilities. These emerging workloads, which may span different geographical areas, need greater bandwidth and higher efficiency when having to interconnect compute, storage, and memory across and/or within a rack at higher speeds. Data centers consisting of hundreds of thousands of servers process massive amount of data driven by cloud computing and big data applications as well as new and emerging workloads such as AI/ML (artificial intelligence/machine learning).
