Pluribus Networks Releases Open Netvisor 2.3 to Support the Ericsson HDS8000 Hyperscale Cloud Offering

Pluribus Networks, the company which provides Netvisor (nvOS), the industry’s most programmable, open-source based operating system for network connectivity, announced the release of Open Netvisor 2.3, which includes direct support for hyperscale data centers used by service-providers. Supporting the Ericsson HDS8000 Hyperscale cloud offering based upon Intel Rack Scale Architecture, Open Netvisor 2.3 enables both out-of-band and in-band management, fabric wide rolling software upgrades, and fast convergence of Layer 3 protocols using BFD (often used to deploy leaf/spine PODs and similar topologies).

Pluribus Open Netvisor 2.3 provides a unique opportunity for the service provider industry by enabling them to allow businesses to drive their foundational infrastructure topology, rather than the other way around. Key features within Open Netvisor 2.3 include:

  • Security enhancements to allow the use of TLS and redundant out-of-band management to secure the control plane for Telco Datacenter needs, which complements the existing SSL support. This secured redundant management is a critical need for service providers as their business is driven by SLA performance.
  • High Availability Cluster-Fabric enhancements include a fabric wide rolling upgrade capability to allow software and security upgrades without any downtime. Pluribus’ Netvisor Cluster-Fabric offers single point of management and control, and now the entire fabric can be upgraded with a single command while the fabric remains in service, eliminating the need for scheduled downtime.
  • The Pluribus Netvisor Cluster-Fabric control plane now operates independent of Layer 2, Layer 3, or VXLAN based overlay networks. Netvisor offers broadcast and loop free Layer 2 topologies (necessary for server virtualization) that can scale to over 1 million MAC entries or Virtual Ports (“vports”) enabling customers to build large Layer 2 networks or build large Layer 3 networks based on BGP/ECMP and use overlays to support Virtual Machine migration. The Open Netvisor 2.3 release also adds BFD support to improve Layer 3 convergence for customers deploying large clouds.

By incorporating this new set of service-provider specific capabilities, Pluribus Open Netvisor 2.3 is now being used by Ericsson within its HDS8000 cloud platform to drive its silicon photonics based switches, as referenced by Intel’s Rack Scale Architecture (RSA). The RSA architecture disaggregates compute, storage, and network resources; introduces the ability to pool these resources; simplifies management of compute, storage, and network resources; and creates the ability to dynamically compose resources based on workload-specific demands.

“Pluribus innovative approach to networking in a hyperscaled data center fits with our vision in creating not only the best in class data center but the tools and capabilities from a network analytics perspective to lay the foundation for a data centric infrastructure. We are very excited to be working with the Pluribus team in building this,” said Howard Wu, Head of Product Line, Hyper Cloud Solution, Business Unit Cloud & IP, Ericsson.

“Ericsson’s use of silicon photonics-based systems allows the Netvisor Distributed and Multi-threaded control plane to offer fabric wide APIs for fine grained control and easy integration into Openstack and other cloud management systems,” said Sunay Tripathi, Pluribus Networks’ CTO and co-founder. “As a result, Netvisor Application level Analytics and Time Machine helps debug and secure the entire infrastructure in a very easy manner.”

The RSA architecture supports the use of Ethernet, SAS, and PCI-Express over Optical links for higher performance, scale and allows individual components in the rack to be upgraded independently from each other. HDS8000 Top of the Rack switches use silicon photonics as integrated circuit components to efficiently convert digital signals to Optical and back to digital, allowing Netvisor running on these switches to create a plug and play fabric that works as one logical control plane independent of the Layer 2, Layer 3, or overlay based connectivity.

Open Netvisor 2.3 will be available in early September 2015.
