N7K-M324FQ-25L特點和優(yōu)勢
由久經(jīng)考驗且廣泛部署的 NX-OS 操作系統(tǒng)提供支持。這些模塊集成了廣泛的數(shù)據(jù)中心交換技術(shù),包括行業(yè)標(biāo)準(zhǔn)和思科自己的創(chuàng)新,例如:
● 通用分組無線服務(wù) (GPRS) 隧道協(xié)議 (GTP) 哈希:此功能使用 M3 系列模塊的高級數(shù)據(jù)包解析功能,為 GTP 數(shù)據(jù)包提供增強的端口通道和等價多路徑 (ECMP) 負(fù)載平衡。
● 虛擬可擴展局域網(wǎng) (VXLAN):VXLAN 使組織能夠為虛擬化環(huán)境構(gòu)建高度可擴展的虛擬覆蓋網(wǎng)絡(luò)。它還提供了所需的架構(gòu)靈活性和敏捷性,以在不同的第 2 層域中使用可重復(fù)的 Pod 擴展云部署,以及跨第 3 層網(wǎng)絡(luò)在服務(wù)器之間遷移虛擬機。
● 高級數(shù)據(jù)中心互連 (DCI) 協(xié)議:思科覆蓋網(wǎng)絡(luò)傳輸虛擬化 (OTV)、定位器/ID 分離協(xié)議 (LISP)、多協(xié)議標(biāo)簽交換 (MPLS) 和虛擬專用 LAN 服務(wù) (VPLS) 等高級協(xié)議為客戶提供了廣泛的技術(shù)選擇,以透明地互連其數(shù)據(jù)中心,并在地理位置分散的數(shù)據(jù)中心站點之間擴展應(yīng)用。
● 虛擬設(shè)備上下文 (VDC):此功能支持將單個物理設(shè)備虛擬化為多個邏輯設(shè)備。每個預(yù)配的邏輯設(shè)備都像單獨的物理設(shè)備一樣進行配置和管理。
● 卓越的集成硬件安全功能:
MAC 安全 (MACsec) 以線速在所有端口上提供 128 位和 256 位加密,在硬件中支持密鑰協(xié)議協(xié)議(安全關(guān)聯(lián)協(xié)議 [SAP] 和 MACsec 密鑰協(xié)議 [MKA])

N7K-M324FQ-25L
★★★英語介紹:
N7K-M324FQ-25L24 Port 40 Gb Ethernet module
The N7K-M324FQ-25L is a versatile I/O module with a comprehensive feature set that delivers wire-speed performance on every port. The module provides deep buffers and high-capacity terad content addressable memory (TCAM), making the module an excellent choice for building high-density, low-latency, scalable data centers.
Product overview
The Cisco Nexus 7000 Series switches are the foundation of the Cisco Unified Fabric solution. Designed to meet the requirements of mission-critical data centers, these switches offer superior availability, excellent scalability, and the proven and comprehensive Cisco NX-OS software data center switching feature set. ?
The Cisco Nexus 7000 Series is the first product in the next generation of data center switching platforms, offering integrated resiliency combined with features optimized for availability, reliability, scalability, and ease of management. The Cisco Nexus 7000 Series switching Matrix architecture scales to more than 17 TBPS and is designed to support high-density 10, 40, and 100 Gigabit Ethernet deployments. Table 1 summarizes the 40 Gb Ethernet port density of switches in this platform.
N7K-M324FQ-25L Features and advantages
Powered by the proven and widely deployed NX-OS operating system. These modules integrate a wide range of data center switching technologies, including industry standards and Cisco’s own innovations, such as:
General Packet Radio Service (GPRS) Tunneling Protocol (GTP) hashing: This feature uses the advanced packet resolution capabilities of the M3 series modules to provide enhanced port channel and equivalent multipath (ECMP) load balancing for GTP packets.
Virtual Extensible Local Area Network (VXLAN) : VXLAN enables organizations to build highly scalable virtual overlay networks for virtualized environments. It also provides the architectural flexibility and agility needed to scale cloud deployments with repeatable Pods in different Layer 2 domains, as well as to migrate virtual machines between servers across Layer 3 networks.
Advanced Data Center Interconnect (DCI) protocol: Cisco covers advanced protocols such as Network Transport Virtualization (OTV), Locator /ID Separation Protocol (LISP), Multiprotocol Label Switching (MPLS), and Virtual Private LAN Services (VPLS) to provide customers with a wide range of technology options to transparently interconnect their data centers. And scale applications across geographically dispersed data center sites.
Virtual Device Context (VDC) : This feature allows you to virtualize a single physical device into multiple logical devices. Each pre-configured logical device is configured and managed like a separate physical device.
● Excellent integrated hardware security features:
?MAC Security (MACsec) provides 128-bit and 256-bit encryption on all ports at wire speed, with support for key protocol protocols (Security Association Protocol [SAP] and MACsec Key Protocol [MKA]) in hardware
