云网络解决方案

云网络的特点如下:

 

  • 可伸缩性: 云网络可以扩展至成千上万个节点,并在整个云内提供无阻塞 Fabric。
  • 低延迟: 延迟时间是改进应用性能的关键所在。 网络需要在大型环境内提供超低的延迟时间。
  • 保证交付: 云必须为包括 HPC 应用、web、视频和数据在内的大量服务提供可预测和可靠的性能。
  • 可扩展的管理: 云网络跨越服务器、企业网络和服务提供商网络之间的所有传统界限。 它们需要在混合型环境下进行管理,通常要求具备针对个体部署的定制能力。 网络管理需要可扩展和可定制,以实现这类应用。
  • 自修复弹性: 随着规模的扩大,网络变得越来越关键,网络故障需要自动得到遏制和修复。

Arista Networks 提供满足上述要求的独特云网络平台。 更多详细信息,请参阅我们的产品和服务部分。

云网络平台

服务器、存储和网络构成了现代 IT 基础架构的锚点。 世界各地的公司都在不断地试图增强这一基础架构。 而使用 10GbE 连接的新基础架构要求则截然不同,与传统企业的 IT 需求在许多方面存在差异。 新环境通常要求独特的计算密度、功率密度和超低的延迟时间。 这类超大型的计算环境(这种环境下通过多达数百万台服务器、存储和网络设备衡量部署状况)正在改变它们与 IT 对接并驱动增长和降低运营费用的方式。

Routing

The foundation of Arista's Routing solutions is to apply the cloud principles of "scale-out, simplify, software-driven networking" to Routing. Arista's Routing solutions allow customers to leverage Arista's 7500R Universal spine platforms powered by EOS for roles that required high performance internet scale routing, with high port density, low power, programmability and automation, which traditional router platforms are unable to offer. Leveraging innovations in platform and EOS to enable features and scale not natively available in merchant silicon, these solutions offer a unique approach to transform legacy routing architectures.
