Driving Innovation with OpenEthernet

Authored by: Amir Sheffer, Sr. Product Manager

For years, data center Ethernet switching equipment has been based on closed, proprietary vendor implementation, providing very limited flexibility for the user. The progress made in open source applications and software can be leveraged in Ethernet switches to create a new generation of open, flexible and customizable solutions.

Switches based on the OpenEthernet approach will replace traditional closed-code switches and will allow data center customization for optimized and efficient operation. The OpenEthernet switch is based on functionality developed by the equipment vendor and integration with public, open cores and tools that can be freely downloaded from the internet.

As a leader of this approach, Mellanox is investing in the integration and development of such tools, which when combined, can provide complete functionality. Examples for such tools can be OpenFlow–for flow configuration; Puppet and Chef–for switch configuration, Quagga for routing protocols, etc.

Open Ethernet

Mellanox switch software runs over Linux.  Even if the Linux kernel provides good infrastructure for the switch, it lacks functionality to connect it to the switching and routing functions. For example, a routing reflector unit is required to synchronize between the Linux kernel, the routing stack and the silicon data path. For this purpose, we are developing and opening such “reflector” units to the open community.

Another example can be the hardware driver or the software development kit (SDK) application interface (API) for the switch. By opening the API to the community, we will be the first ones to enable full flexibility and ease-of implementation to our customers and we believe other will follow.

In parallel, Mellanox is participating in industry-wide groups that are taking a similar approach.  One example can be the OpenStack community, in which Mellanox is an active member. Another example for such group can be the Open Compute Project (OCP), which is defining open and standard equipment for data centers. Mellanox already builds OCP-compatible NICs and has recently contributed the hardware design documents of the SX1024 switch system to OCP.

So far, we have briefly touched several aspects of OpenEthernet. An important feature that will be explained in the coming weeks is the hardware – software separation.

The Storage Fabric of the Future Virtualized Data Center

Guest post by Nelson Nahum, Zadara Storage

It is evident that the future data center will be based on cutting-edge software and virtualization technologies to make the most effective use of hardware, compute power, and storage needs to perform essential analytics and to increase the performance of media-related and advanced web applications. And it turns out that the wires that will connect all this technology together are no less crucial to next-generation data centers and clouds than the software and virtualization layers that run within them.


There are multiple storage fabrics and interconnects available today, including Fibre Channel, Ethernet and SAS. Each has various pros and cons, and fabrics were chosen according to need of performance, compatibility and cost efficiencies.

 

As an enterprise storage as-a-service provider, delivering a software-based cloud storage solution for public, private and hybrid cloud models based on commodity hardware, Zadara Storage provides storage as-a-service in multiple public cloud and colocation facilities around the globe. Consistency, high availability and predictability are key in supplying the scalable, elastic service our customers expect, regardless of their location, facility or the public cloud they employ. The hardware we use needs to be dependable, pervasive and cost-efficient in order to sustain the performance and cost-level of our service, anywhere and at any scale.

 

When choosing our fabric, Ethernet came as a clear choice. Ethernet is likely to become the new standard, and boasts several advantages vital to our product:

  • Ethernet’s speed roadmap is aggressive: from 10GbE to 40GbE, and upcoming 100GbE
  • Ethernet is ubiquitous: we can employ it with no complication at any data center or colocation facility around the globe
  • The latency we have found to be more than manageable, specifically as we use advanced techniques such as IO virtualization and data passthrough
  • Ethernet is the most cost effective: an as-a-service company needs to have a competitive pricing edge.

The future of enterprise storage
The future of Enterprise Storage lies in software and a choice of hardware (premium or commodity). Software-defined storage can scale performance more easily and cost effectively than monolithic hardware, and by combining the best of hardware of software, the customer wins. Ethernet is a critical element of our infrastructure, and Mellanox switches offer significant higher performance and consistent dependability that enables our storage fabric and meets our customer’s needs.
