Facebook Rethinks In-Region Data Center Interconnection “East-west” traffic volume outstrips capabilities of the most powerful switches on the market. With a speedy, reliable connection in place, physically separate data centers can more easily share resources and balance workloads. Because EoMPLS is a transparent service, technologies such as VSS and vPC can be supported over the pseudo wire. If an organization owns its own fiber or rents dark fiber, then any DCI technology would be supported. Facility location affects data center interconnection more than you might expect. I understand I can unsubscribe at any time. In this blog, I'll look at different options for DCI and how well they fulfill our design requirements for a DCI.

Data Center Interconnection: As a neutral supplier of data center services, we enable you to access a large diversity of high quality international IP-transit providers. Virtual Extensible LAN (VXLAN) is a technology used to scale beyond 4096 VLANs and build L2 networks over a L3 infrastructure -- a so-called overlay protocol. IDC explains how creating value, growth, and competitive advantage through new offerings, new business models and relationships requires 3rd Platform IT and interconnection-oriented architectures. There are five key challenges to consider when implementing DCI: DCI technology sits at the center of the burgeoning web-scale world—an unforgiving marketplace in which there’s one chance to get it right. This solution is completely standards-based and can be deployed over existing routed TCP/IP transport networks.. This site is operated by a business or businesses owned by Informa PLC and all copyright resides with them. Does EoMPLS fare any better than VSS or vPC as a DCI? 4.2.4 Interconnection of Modular Data Centers. The implementation of VXLAN may or may not support caching of ARP responses and it’s an optional feature that has to be enabled for broadcast reduction. OTV helps control unicast flooding because it works  on the assumption that there are no silent hosts, so all hosts should be known. Informa PLC is registered in England and Wales with company number 8860726 whose registered and head office is 5 Howick Place, London, SW1P 1WG. Copyright © 2020 Ciena Corporation.

While it is true that some VM mobility … Drittens Software, die die Übertragung steuert. Most network designers would prefer that data center interconnection over wide area networks (WAN) be performed at layer 3, without layer-2 connectivity spanning data centers. Learn about who we are and what we do. Interconnection networks are composed of following three basic components − 1. Think power systems, cooling, solutions, data center contracts and more. I will focus on Layer 2 DCI technologies because these are more complex to implement and have more design considerations than Layer 3 DCI technologies. The most connected data centers at the network core in preeminent locations throughout the USA. VSS turns two physical devices into single logical device by sharing the control plane between the devices. Aimed predominantly at short-reach, single-span fiber optic links for Data Center Interconnect (DCI), 400ZR is an interoperable networking Implementation Agreement (IA) in progress by the OIF. In that case, OTV is your best current option. LONG-TERM STABILITY . The data center interconnect application has emerged as an important and fast-growing segment in the network landscape. in datacenter network design ... social networking, and large-scale scientificand data-intensive applications (such as weather forecasting, healthcare, bioinformatics, and data mining). These data centers don’t exist in isolation. You have subscribed successfully. Capacity: Data centers store and deliver the data applications require. With VSS, a loop-free topology is created between the data centers. Don't miss out! Virtual Private LAN Service (is a multipoint-to-multipoint technology that also uses MPLS for encapsulating frames. Switches− A switch is composed of a set of input and output ports, an internal “cross-bar” connecting all input to all output, internal buffering, and control logi… But one of the most common uses of DCI is to pool resources to scale data center capacity as demand ebbs and flows. This is the most expensive option. It’s also possible for an organization to deploy VPLS in their network. Fortunately, DCI technology enables the smooth transit of critical assets over short, medium and long distances between data centers. This design guide describes an Arista solution for providing simple, robust, and cost-effective datacenter interconnection (DCI) that enables layer-2 services to be bridged between multiple sites over existing layer-3 IP networks. Data Center Interconnect (DCI) technology connects two or more data centers together over short, medium or long distances using high-speed packet-optical connectivity. OTV does not have built-in policers for BUM traffic at the data center edge, but since it separates STP domains and does not flood unknown unicasts, a Layer 2 storm would not have the same impact as it would with the other  technologies. … vPC and VSS create loop-free topologies, but it’s important to note that they are simply VLAN extension technologies without any optimizations designed for DCI. Businesses depend on the reliability of a data center to ensure that their daily IT operations are always functioning. Today’s centralized cloud is comprised of more than 10,000* data centers scattered across the globe. Do you want to learn more about Ciena's products? … Network Computing is part of the Informa Tech Division of Informa PLC. Data centers have proliferated in recent years—there are now more than 7,500 around the globe, with 2,600 packed into the top 20 global cities alone. All data centers are essentially buildings that provides space, power and cooling for network infrastructure. If all hosts are known, then there is no need to flood frames. Any DCI technology can be used over fiber, such as Ethernet over MPLS, Virtual Private LAN Service, Cisco Overlay Transport Virtualization, and also support running link bundles between the data centers. a Facebook datacenter under the control of Facebook. In fact, neither will help with controlling of unicast flooding. It defines a footprint-optimized solution for transporting 400Gb Ethernet over DCI links targeting a minimum of 80 km. Before moving onto DCI technologies, let's look at two clustering technologies that can be used to remove the physical loop caused by the Spanning Tree Protocol (STP). With VXLAN, controlling of unicast flooding  is somewhat controlled by having the tunnel endpoints join a multicast group, but it doesn’t truly prevent flooding of frames. But you may not be able to avoid the complexity of a L2 DCI, either because of poorly designed application or virtualized workloads. Equinix,Inc. They can snoop ARP responses and cache locally so that when the next host ARPs for the MAC, it will already be known by the OTV device, which can answer locally. The multi-tier data center model is dominated by HTTP-based applications in a multi-tier approach. Thank you! Informa PLC's registered office is 5 Howick Place, London SW1P 1WG. It’s also possible to create the same design with Nexus switches and vPC, which makes two Nexus switches appear as one to neighboring devices, but the switches do not actually share the control plane. An organization can either deploy EoMPLS itself or buy a circuit from a service provider. VLANs can then be extended over the port channel between the data centers. Integrated building ownership and Meet Me Room management protect your business for the long-term. View all. Natürlich ist e… Number 8860726. As a network designer or operator, therefore, it is imperative to first understand the needs of the modern data center, and the network topology that has been adapted for the data centers. Equinix offers the best platform needed to leverage 3rd Platform … However, without a strategic location, these benefits can be compromised. This is where our journey begins. The multi-tier approach includes web, application, and database tiers of servers. They also don't help with broadcast reduction at the data center edge since they don't implement any form of proxying of ARP messages, or policing of BUM traffic at the DC edge. In recent years, the scale of the DCN has constantly increased with … Some large operations use DCI to connect their own data centers within their extended enterprise infrastructures, while others connect to partners, cloud providers or data center operators to enable simpler data and resource sharing or handle disaster recovery needs. 4.2 Data-Center Design and Interconnection Networks. Overlay Transport Virtualization (OTV) is one of the few technologies designed for DCI. The most effective transport for DCI is high-speed packet-optical connectivity built on technological innovations such as coherent optics. OTV devices also help reduce broadcasts. Subscribe now for the latest Network Insights. In fact, it arguably performs worse since it sends anything out that comes in. Copyright © 2020 Informa PLC. These technologies -- virtual switching system (VSS) and virtual Port Channel (vPC) -- decrease the role of STP but do not completely remove it from the network. Design > Networks. However, VPLS doesn't help control unicast flooding, reduce broadcasts, or police BUM traffic. There is no policing of BUM traffic; manual policers would have to be implemented and these would normally be per port and not per VLAN. I agree to subscribe to Ciena's communications. Extending L2 between data centers will always add the risk of both data centers collapsing at the same time. Registered in England and Wales. Data Center Frontier, in partnership with Open Spectrum, brings our readers a series that provides an introductory guidebook to the ins and outs of the data center and colocation industry. An analysis of the various technologies available for Layer 2 DCI, including Cisco Overlay Transport Virtualization. Future releases of VXLAN and Ethernet VPN (EVPN) may prove to be as good as OTV or at least good enough for L2 DCI. Unchecking this box will prevent you from subscribing to Ciena's communications. Gartner, Magic Quadrant for Data Center and Cloud Networking, Andrew Lerner, Evan Zeng, Jonathan Forest, 30 June 2020. Before extending L2 between your data centers, make sure that your business drivers and recovery objectives require this added complexity. Preferably, there should be support for multicast, but it can run in unicast mode as well. where he focused on the development and verification of the best practices for Network Virtualization and Identity related technologies for Cisco Campus Networks. Our low-profile building design allows a high level of security within the data center. Marketplace. In the next five years, driven by a need to get data and applications closer to end-users, both humans and machines, tens of thousands of additional scaled-down data centers will sprout up at the edge of the network to form the Edge Cloud. They need to talk to each other—share data and content, and provide back-ups and redundancy. A fiber or dense wavelength division multiplexing-based solution is often needed to extend storage between two data centers. Curry noted that interconnection and network design are the foundation of a successful hybrid environment, but it is easy for people to not think about network, as it is often bundled with a solution from a provider. Jake Howering, Product Manager, Systems Development Unit (SDU), Cisco Systems Jake Howering, a 12 year Cisco veteran, is the Data Center Interconnect (DCI) Product Manager in the Cisco Sys-tem Architecture and Strategy Unit. Links− A link is a cable of one or more optical fibers or electrical wires with a connector at each end attached to a switch or network interface port. In another example of inter-data center interconnect, is if a certain video is getting a lot of views, the video is not only kept in its central location, but copies of the video are pushed to metro data centers where access is quicker because it’s stored closer to the user, and the traffic doesn’t tie up long haul networks. RESOURCE LIBRARY CUSTOMER STORIES CONNECT[ED] BLOG Carrier list. Enabled by advanced coherent optical technology design targeting small, pluggable form factor modules such as QSFP-DD and OSFP, 400ZR proposes a technology-driven solution for high capacity data transport, matched to 400GE switch port market introduction. Watch a video, read a customer testimonial, reference white paper research and review collateral covering our data center facilities and industry topics.
