Automate the Fabric

If you search the internet for data center automation tools, you will come up with many options. You can easily find software tools that automate server provisioning, network equipment configuration or monitor the different elements. But you cannot find tools for automatic fabric configuration.

Fabrics become more popular these days. If traditional aggregation switching in data centers of Cloud providers, Web 2.0 providers, and large-scale enterprises has been based on modular switches, we now see them being replaced by fabrics – arrays of fixed, 1U switches. These fabrics increase the flexibility and efficiency in data center aggregation – lower cost of equipment, power reduction, better scalability and high resiliency.

Mellanox Virtual Modular Switch™ (VMS) is such a fabric, comprised of Mellanox 10, 40, and 56GbE fixed switches. It provides an optimized approach for aggregating racks. The VMS excels in its flexibility, power savings and performance.  Based on Mellanox switches, the VMS leverages the unique advantages of the SwitchX-2, the highest performing 36-port 40GbE switching IC.

The Need for Automation

The scalability that the fabrics bring drives a change in the way they are configured. The legacy way to configure switches and routers is scripting – each device has its management interface, typically CLI, and when the right configuration script is applied to each switch, they interwork as a single fabric. However, this approach does not scale and one cannot configure big fabrics in mega data centers this way, since creating and maintaining scripts for many fixed switches can become a nightmare. So, fabric creation automation is required – a tool that can do it both automatically and fast, to allow short setup time.
