The 8400: A Core Switch that Makes Every Network Device Better

篮球是我最喜欢的运动。我吸引it on many levels. Individual skills are to be marveled at, of course, but more important is teamwork. A player who makes everyone else on the team better is truly great. Magic Johnson comes to mind. He understood the characteristics of every player on his team and made sure they each got the ball so they could do the things they did best.

网络很像篮球。网络开关应该像一个出色的路人,将每个连接的设备视为具有独特目的的智能网络播放器。就像在篮球中一样,这些网络玩家正在移动 - 迅速在球场各地移动。

Today, mobile devices are the way people connect to their apps and services. And mobile users and their traffic might be anywhere, at any time. A large number of wireless users in one room all accessing video will create large amounts of highly localized traffic. That traffic could disperse to different locations, only to regroup later somewhere else.

除了移动设备外,物联网(IoT)设备在企业边缘的数量越来越多。根据IDC高级副总裁兼首席分析师弗兰克·盖斯(Frank Gens)的说法,到2025年,将有800亿个连接的物联网设备。设备类型的多样性及其相关的安全概况和行为非常高。我们需要新的方法来动态细分它们,并监视它们是否有可能由企业内较高价值资产的黑客利用的潜在漏洞。

这些流动性和物联网的双重趋势共同以深刻的方式改变了网络。他们使我们重新考虑了较旧的建筑和管理网络模型。

At Aruba, a Hewlett Packard Enterprise company, our experience with connecting mobile devices has taught us lessons that apply to the entire access network. Traditional wired network design principles are based on the premise that topology changes in the network are few and far between. This sufficed in a world where IT dictated pace and control over all devices and apps. With the introduction of mobility, a new overlay architecture was necessary to handle the rapid topology changes expected from mobile devices. The overlay separated mobile devices into a more flexible security and policy domain that was independent of the rigid underlying infrastructure.

覆盖体系结构的能力丰富性提出了有趣的问题,围绕着为什么无法将其扩展到所有设备,而与网络连接无关。完全接受这个概念,使我们研究了边缘的核心和聚合层。我们需要灵活的开关,以锚定完整的边缘底层,以简化网络操作并支持由移动性和物联网定义的不断发展的连接世界。

引入Aruba 8400开关

今天我们正在介绍Aruba 8400开关,第一个核心和聚合开关在移动领先时代的地面上从头开始设计。Aruba 8400并没有支持当今的动态用例和过去的平台限制,而是一个全新的起点,旨在满足现代世界的需求。

With 19.2 Tbps of switch capacity and carrier-class high availability, the Aruba 8400 is up to the task of playing team anchor at the core. Its features include:

  • 冗余管理模块
  • 冗余面料
  • 单独的现场更换风扇和电源
  • 被动中间平面
  • 多线卡支持10G,40G和100G端口。

就像硬件功能一样令人印象深刻,我对Arubaos-CX启用的新可能性感到非常兴奋,现代的操作系统为8400供电。Arubaos-CX专门为摆脱了旧操作系统供电的旧操作系统的刚性和不灵活性而设计常规的核心/聚合开关。

Arubaos-CX的一些亮点包括:

以数据库为中心的设计:由于操作系统是从头开始构建的,因此这确实是现代时代的转换。借助以数据库为中心的设计和整个数据库架构的程序化接口,网络运营商可以在交换机内访问基于REST的API,以便在交换机内访问每个网络功能和状态。这些API可以访问一组丰富的遥测数据,这些数据可以无缝合并到外部管理平台和服务中,以进行高级可见性和故障排除,从而提高了问题检测速度,诊断和解决方案的速度,

Programmability: Brittle and stateless CLI scripts for configuration and management are now headaches of the past. The use of true REST API's allows integration into many systems, for example, spreadsheet functions, bringing the power of programmability to the non-programmer. And since the configuration is stored in a structured database instead of a text file, rolling back changes is easier than ever, thus dramatically reducing a risk of downtime and performance issues.

可扩展性:Arubaos-CX包括一个网络分析引擎,该引擎支持微服务扩展功能以对网络和特定业务关键应用程序进行故障排除。Arubaos-CX网络分析引擎(NAE)包括一个Python沙盒,可完全访问内部数据库和Prometheus时间序列数据库,以获取任何相关细节。这使操作员可以在交换机上编程代理,监视事件,在事件发生时收集数据以及实时对它们做出反应。整个Aruba 金宝搏188合伙人Airheads社区将合作创建这些代理商。

New extensions can be created and deployed in the field to enhance monitoring, visibility, and troubleshooting needs for custom apps.

As you can see, we have now brought the flexibility and programmability of the mobility overlay down to the bare metal of our foundational core and aggregation layers powering the edge. With this new architecture, our customers will be able to accelerate innovation. Thanks to its highly programmable software approach, the Aruba 8400 has the orchestration capabilities needed to bridge a new world of end-user mobility and smart-building IoT. As it turns out, many of the innovations we created for wireless make the wired world work better too. A lot like Magic Johnson, the Aruba 8400 makes every network device better.
