Data center switch to power cloud network

Data CenterWith the increase of IT construction costs, the scale is becoming larger and larger, mainly reflected in the increasing demand for data storage, data mining, and high-performance computing. In the next few years, more and more enterprises will begin to adoptCloud computingTechnical data center to improve the efficiency of its IT infrastructure.

For the new features of the next generation of data centers, ruijie network has recently launched a new series of data center switches that support cloud computing. New products provide comprehensive support for the latest network technology standards, making the industry one of the biggest challenges. These new technologies and new features include more bandwidth, lossless low-latency Ethernet, layer-2 routing, and simplified network layers. They seem to be ahead of schedule, but they are all indispensable for the future construction of cloud networks, it is also urgently needed to build a cloud network. The data center product family includes six products in the core and access layer series, all of which are designed based on the G platform and four 40G modules with four ports. The new 40g module mainly includes core layer RG-S12000 Cloud Computing Series and access layer RG-S6000 series, two series are equipped with 40g module equipment, and the hardware chip supports the next generation of data center and Cloud Computing network features.

Taking product RG-S6200-48XS as an example: RG-S6200-48XS is the first box switch in the industry that supports 48 10g line speeds and the next generation data center network features. The host has fixed 0.32 million mb sfp + optical port, including 1 expansion slot and 1 expansion slot. It can expand 16 SFP + 10G modules or 4 40G modules ), the whole machine supports 48 10 Gbit/s or 32 10 Gbit/s + 4 40 Gbit/s line speeds. Full 10 Gigabit Port form, plus scalable 40g port, suitable for access layer of super large data center 10 Gigabit server access), or convergence layer or core layer of Small and Medium data center network.

The new application trend requires that the network of the Next Generation data center should have some key characteristics, including network security integration capabilities, unified switching, 10G port density, 40G/G interface support capabilities, virtualization capabilities, burst traffic absorption capabilities, IPv4/IPv6 support capabilities and energy-saving capabilities. It also needs to support some of the latest standards: FCoE, DCB, VEPA, TRILL and so on.

Key Technology Analysis

FCoEFibre Channel over Ethernet) and DCBData Center Bridging are key standards for data Center network convergence. Although they have not yet been officially promulgated, they are almost completed. VEPA virtual Ethernet port aggregation, one of the edge virtual bridging standards in DCB, is receiving increasing attention. This standard is related to server virtualization and can solve communication problems between virtual machines, unmount the soft switch used by the virtual machine, release server resources, and solve network visibility and deployment of the entire network policy. VEPA is expected to be approved by mid-year.

The TRILL multi-link transparent Interconnection protocol of IETF can meet the network scalability and elasticity requirements of cloud computing. TRILL is equivalent to a layer-2 routing protocol. It has two-layer MAC bridging and three-layer IP routing functions. It applies the multi-path transmission mechanism to forward/route data traffic. The TRILL protocol is proposed to avoid the disadvantages of using IEEE 802.1D to quickly generate a Tree Protocol.

The virtual chassis simplifies the data center network layers from Layer 3 to Layer 2, flattening the data center network and improving the efficiency of Inter-server communication.

New products under the new standard

Currently, the 40/100G Ethernet standard has been officially approved. The establishment of this standard puts forward more stringent and advanced technical requirements for next-generation data center network equipment, such as port capacity and interface density. In terms of products, Extreme Networks, Force10 networks, and BLADE networks have announced that vswitches support 40G Ethernet port modules, cisco, Juniper, brocade, and Arang announced the release of G Ethernet interfaces in their routers.

According to Xiang Xiaosheng, product line director of ruijie network switch, ruijie's switch product line for next-generation data centers has the following features: Unified Exchange, integrated storage and Ethernet, FCoE support for all products, and line rate products for all products, suitable for large-traffic data centers, which can help build a non-blocking performance switching network. All products support the virtualization feature of data centers and re-return the switching function of virtual machines to network devices according to the VEPA standard, effectively integrate the entire data center into a network, making the network simpler. The entire line of products can build a TRILL transparent exchange network, laying the foundation for virtualized cloud computing.
