They offer extensive network traffic reporting to help IT team optimize network architecture and adjust resource deployment. Even multi-core servers are supported with bandwidth, low latency, and low-jitter through the top-of-rack switches. They can improve server traffic latency and data throughput issues, providing better stability. Here are the other advantages of TOR switches bring:
High-performance TOR data center switch can handle L2 and 元 traffic forwarding, data center bridging, and fibre channel over ethernet (FCoE) for the entire server rack. Also, TOR switches can use both ethernet and optical ports. Top-of-rack switches support 25G/40G/50G/100G port types, as well as managed ports, featuring high backplane bandwidth. Of course, they also have high capacity forwarding features and supports 32/48/64/128 ports high-density ethernet boards. The top-of-rack switches adopt a distributed cache architecture, which can accurately identify and control data to achieve zero packet loss. EVPN is one of the extensions of BGP that allows the network to carry network layer reachability information (NLRI) and provides multipath forwarding and redundancy through an all-active mode, and convergence with VXLAN can greatly improve network performance.Ĭache and capacity. The applications of virtualization technologies are PFC, EVPN-VXLAN, MLAG, and ECN. Further, the operating system also offers some basic features, such as L2/元/ACL/QoS/security, as well as open RPC API. TOR switches, undertaken by box switches of 1U to 2U in height, have powerful CPU performance and switching chips, which can provide reliable and stable L2/元 network switching services. What are the essential performance characteristics of a top-of-rack switch in a high-density data center network? Here is the answer for you. It can be used as an access switch or an aggregation switch to connect user data or aggregate data from the access layer.
Generally speaking, deploying the switch on the top of the cabinet is the most conducive to routing, so the top-of-rack architecture is most widely used. In fact, the core of TOR is to deploy the switch in the server cabinet, whether on the top of the cabinet, in the middle of the cabinet, or on the bottom of the cabinet. Top-of-rack switch, called a TOR switch, is placed on the top of a rack cabinet. What Do You Know About the Top-of-rack Switches? This article will focus on top-of-rack switches. End-of-rack switches are more suitable for traditional data centers that do not require high scalability, while top-of-rack switches are more suitable for access switches or aggregation switches in modern data centers with high scalability. The applications of these two network architectures are different. With the development of data centers, two network architectures have been derived: TOR and EOR.
