Cisco Nexus™ 7000 VDC与Juniper逻辑路由器作者：Shiyu Meng五一节确实应该勤劳一点，当然按照惯例得先帖一段概述性语言，不单纯为了写blog，更重要的是以后用来写标书的时候还用得上。

VDC与逻辑路由器的设计理念，其实大部分都相同，所以你完全可以参考两家的概念去描述同一个对象。

同时，也没必要真的去比较谁更优秀或者谁先谁后的问题了，技术真正的价值在于应用部署而不仅仅在实验室内部。

所以假如你之前了解过Juniper JUNOS上实现的逻辑路由器的概念，那么很容易就能将相关的经验迁移到Cisco N7K的VDC当中去。

由于维护不断扩大的IT基础设施不仅成本高昂，而且效率很低，因此很多企业都开始实施大规模的基础设施整合计划。

虚拟化技术让IT部门可以在多个逻辑职能之间共享一台物理设备，最大限度地利用现有资源。

这可以避免将整个设备专门用于单一职能，导致物理设备的利用率过低。

不同的虚拟化级别根据故障遏制和管理分离的层次要求，可以对设备执行多种不同级别的虚拟化。

决定网络设备虚拟化级别的主要组件包括：控制平面：创建多个独立控制平面例程的能力让用户可以创建多个逻辑拓扑和故障域。

∙数据（或者转发）平面：用户可以通过对转发表和其他数据库进行分区，实现数据隔离。

∙管理平面：可以为每个虚拟设备独立提供精简的管理环境。

∙软件分区：可以将模块化软件进程合并到专门用于特定虚拟设备的分区之中，从而创建明确定义的故障域。

∙硬件组件：用户可以对硬件组件进行分区，将某个分区专门用于特定的虚拟设备，从而以可预测的方式，将硬件资源分配给不同的虚拟设备。

系列可以通过虚拟交换机技术（VDC），支持所有这些不同对于虚拟化的需求计算、存储和网络基础设施资源的容量和功耗在最近几年中大幅增加。

与此同时，对于这些资源的需求也在不断增长。

这两个因素导致分布式基础设施资源的迅速扩散，但同时也使得一些过剩的、没有得到充分利用的基础设施容量散布于整个网络之中。

Data SheetCisco Nexus 7700 Platform Power SuppliesThe Cisco Nexus® 7700 platform switches are the latest extension to the modular Cisco Nexus 7000 Series Switches. The Cisco Nexus 7700 switches have operational and feature consistency with the existing Cisco Nexus 7000 Series Switches, using a common system architecture, the same application-specific integrated circuit (ASIC) technology, and the same proven Cisco® NX-OS Software releases.The Cisco Nexus 7700 AC and DC power supply modules (Figures 1 and 2) deliver fault tolerance, high efficiency, load sharing, and hot-swappable power features to the Cisco Nexus 7700 switches. The Cisco Nexus 7700 switches use 3.0-kilowatt (kW) power supplies that are 90 percent efficient or greater, so less power is dissipated as heat, and more power is available to the system to use than with typical power supplies. The high-efficiency 3.0-kW power supplies allow a smaller power configuration and provide flexible power provisioning.The maximum output for the 3.0-kW AC power supplies is 1400 or 3000 watts (W) if input power is 110 or 220 VAC respectively, and the dual input 3.0-kW DC power scale is 1500 or 3000W if one or two inputs respectively are active. Both the AC and DC versions support multiple system-level redundancy options for greater availability. Designed to address high-availability requirements, the power supplies incorporate internal component-level monitoring, temperature sensors, and intelligent remote-management capabilities.The power supplies are fully hot swappable, helping ensure no system interruption during installation or upgrades. They are fitted at the bottom front of the Cisco Nexus 7700 chassis, allowing installation and removal without disturbing the network cabling of the I/O modules.Figure 1. Cisco Nexus 7700 3.0-kW AC Power Supply ModuleFigure 2. Cisco Nexus 7700 3.0-kW DC Power Supply ModuleCisco Nexus 7700 3.0-kW AC Power SupplyThe 3.0-kW AC power supply module for the Cisco Nexus 7700 switch is a single 20-ampere (A) AC input power supply. Connection to high line nominal voltage (220 VAC) will produce a power output of 3000W. Connection to low line nominal voltage (110 VAC) will produce a power output of 1400W. Table 1 shows the available power output for the input options.Table 1. Available Output Based on Input PowerCisco Nexus 7700 3.0-kW DC Power SupplyThe 3.0-kW DC power supply has two isolated input stages, each delivering up to 1500W of output power. Each stage uses a -48V DC connection. The power supply will deliver 1500W when only one input is active and 3000W when two inputs are active.Table 2 shows the available power output for the input options.Table 2. Available Output Based on Input PowerFigure 3 shows the connections to the power supply inputs.Figure 3. Cisco Nexus 7700 3.0-kW DC Power Supply Module Connections and Power RatingsCisco Nexus 7700 Platform Power Supply RedundancyThe power supplies on the Cisco Nexus 7700 chassis provide multiple load sharing and fault tolerance and are hot swappable. A maximum of 2 power supplies are supported on the Cisco Nexus 7700 2-Slot Switch, a maximum of 4 power supplies are supported on the Cisco Nexus 7700 6-Slot Switch, a maximum of 8 power supplies are supported on the Cisco Nexus 7700 10-Slot Switch, and a maximum of 16 power supplies are supported on the Cisco Nexus 7700 18-Slot Switch. The 2, 4, 8, and 16 power supply bays for the 6-slot, 10-slot, and 18-slot Cisco Nexus 7700 platform chassis, respectively, are designed for redundancy and future growth.Use of multiple smaller power supplies provides flexible power provisioning and redundancy in the event of power supply failure. These power supplies also support grid redundancy to allow for grid failure or failure of facility components such as an uninterruptible power supply (UPS) or a circuit breaker.Cisco Nexus 7700 systems can operate in four user-configurable power-redundancy modes, summarized in Table 3, to meet the redundancy needs of the environment.Table 3. Power-Redundancy ModesThe total amount of power available to the Cisco Nexus 7700 switch depends on the type of power supplies installed and the configured power supply redundancy mode. The 3.0-kW AC power supply supports operation with 110 and 220V, which results in different levels of output power for the different redundancy modes. The 3.0-kW DC power supply supports single or dual input, which results in different levels of output power for the different redundancy modes.Features and BenefitsTable 4 summarizes the features and benefits of the Cisco Nexus 7700 3.0-kW AC power supply modules.Table 4.

Data SheetCisco Nexus 7000 Series 32-Port 1 and 10 Gigabit Ethernet ModuleProduct OverviewThe Cisco Nexus® 7000 Series 32-Port 1 and 10 Gigabit Ethernet Module offers outstanding flexibility and performance, with extensive virtualization and multipath capabilities. The module enables the deployment of high-density, low-latency, scalable data center architectures.The Cisco Nexus 7000 Series 32-Port 1 and 10 Gigabit Ethernet Module (Figure 1) is the first of the Cisco Nexus 7000 F-Series Ethernet Modules, extending the capabilities of the Cisco Nexus 7000 Series in the data center. Powered by the F1 Forwarding Engine, the module delivers 480 million packets per second (mpps) of distributed Layer 2 forwarding and up to 320 Gbps of data throughput through a custom dedicated forwarding application-specific integrated circuit (ASIC), enabling the creation of extensible data centers. A Cisco Nexus 7000 18-Slot Switch fully populated with Cisco Nexus 32-Port 1 and 10 Gigabit Ethernet Modules has the capability to deliver upto 10.2 terabits per second (Tbps) of switching performance, with a typical power consumption of less than 10 watts (W) per port.Figure 1. Cisco Nexus 7000 Series 32-Port 1 and 10 Gigabit Ethernet Fabric ModulePowerful access control list (ACL) processing supports 32,000 per module, ingress and egress, with the ACL entries addressing Layer 2, 3, and 4 fields. The F1 forwarding engine also supports applications requiring port mirroring with integrated hardware support for 16 simultaneous unidirectional switched-port analyzer (SPAN) sessions per module.Additionally, the F1 series delivers integrated hardware support for Fibre Channel over Ethernet (FCoE) and IEEE Data Center Bridging (DCB) features, greatly simplifying the network infrastructure and reducing costs by enabling the deployment of unified data center fabrics to consolidate data center traffic onto a single, general-purpose, high-performance, highly available network.The Cisco Nexus 7000 F-Series modules, when combined with the powerful Cisco® NX-OS Software, deliver Cisco FabricPath multipath Ethernet technologies based on IETF Transparent Interconnection of Lots of Links (TRILL). Cisco FabricPath comprises a set of multipath Ethernet technologies combines the reliability and scalability benefits of Layer 3 routing with the flexibility of Layer 2 Ethernet networks. With Cisco FabricPath, organizations can now build massively scalable, flexible networks that efficiently use available bandwidth between nodes, offering improved network resiliencyCisco FabricPath offers a topology-based Layer 2 routing mechanism that provides an equal-cost multipath (ECMP) forwarding model. Cisco FabricPath implements an enhancement that resolves the MAC address table scalability challenge characteristic of switched Layer 2 networks. Enhanced virtual PortChannel (vPC+) is another technology offered by Cisco FabricPath. Similar to vPC, vPC+ allows the redundant interconnection of the existing Ethernet infrastructure to a Cisco FabricPath fabric without relying on Spanning Tree Protocol.The benefits of Cisco FabricPath include:●Operational simplicity: Cisco FabricPath embeds an autodiscovery mechanism that does not require anyadditional platform configuration. By offering Layer 2 connectivity, this “VLAN anywhere” characteristicsimplifies provisioning and offers workload flexibility across the network.●High resiliency and performance: Since Cisco FabricPath is a Layer 2 routed protocol, it offers stability,scalability, and optimized resiliency along with network failure containment.●Massively scalable fabric: By building a forwarding model on 16-way ECMP, Cisco FabricPath helps preventbandwidth bottlenecks and allows capacity to be added dynamically, without network disruption.The Cisco Nexus 7000 Series 32-Port 1 and 10 Gigabit Ethernet Module delivers up to 512 ports per chassis, capable of flexibly supporting both Gigabit and 10 Gigabit Ethernet on a per-port basis. Both Small Form-Factor Pluggable (SFP) and SFP+ optics are available for long- and short-haul applications, including Twinax support, for rack-to-rack data center applications, enabling migration and support for numerous deployment scenarios requiring different media types. Table 1 summarizes the features and benefits of the Cisco Nexus 7000 Series 32-Port 1 and 10 Gigabit Ethernet Module.Table 1.

Use of an ordinary patch cord with MMF, 1000BASE-LX/LH SFPs, and a short link distance (tens of meters) can cause transceiver saturation, resulting in an elevated bit error rate. In addition, when using the LX/LH SFP with 62.5-micron-diameter MMF, you must install a mode-conditioning patch cord between the SFP and the MMF cable on both the transmit and receive ends of the link. The mode-conditioning patch cord is required for link distances greater than 300m. ***** 1000BASE-ZX SFP can reach up to 100 km by using dispersion-shifted SMF or low attenuation SMF; the distance depends on fiber quality, number of splices, and connectors.Note: See the SFP optics data sheet for additional information:/en/US/prod/collateral/modules/ps5455/ps6577/product_data_sheet0900aecd8033f885.html.
