Plexxi

Plexxi, Inc. operated as a provider of hyperconverged networking systems tailored for software-defined data centers. Founded in 2010 by David Husak, Ephraim Dobbins, and Mat Mathews, the Nashua, New Hampshire-based company aimed to modernize data center networking. The founders, described as networking professionals, identified the complexity and inefficiency of traditional data center networks as a core problem to solve. Plexxi's business model revolved around providing a comprehensive suite of tools, from hardware switches to management software and application integrations. This approach was designed to help applications perform more effectively and align with business speed.

The company's core offering was a software-defined data fabric that focused on applications rather than the underlying physical infrastructure. This system challenged traditional hierarchical network topologies, like leaf-spine, by proposing a single-tier design that could reduce the number of required switches. Plexxi's product line included hardware switches, Plexxi Control for workload optimization, and Plexxi Connect for workflow automation. The software could automatically detect workloads from platforms like VMware and Nutanix, and then create isolated topologies with dedicated bandwidth to optimize performance. A key concept was "Affinity Networking," which used algorithms to define relationships between applications and network resources, allowing for dynamic and automated network adjustments based on real-time needs. This enabled a more flexible, scalable, and cost-effective approach to network architecture, allowing clients to build for current needs and scale incrementally.

After raising over $80 million in funding from investors including Lightspeed Venture Partners, Matrix Partners, and Google Ventures, Plexxi established itself in the software-defined networking (SDN) market. The company's trajectory culminated in its acquisition by Hewlett Packard Enterprise (HPE) in mid-2018. The deal, finalized on June 1, 2018, was a strategic move for HPE to bolster its hyperconverged and composable infrastructure offerings. Plexxi's technology was integrated with HPE's SimpliVity and Synergy product lines to create a unified solution combining compute, storage, and data fabric networking under a single management interface.
