Overview
Silver Peak Systems was a United States networking technology company that developed products for improving the performance, reliability, and manageability of wide area networks. Its portfolio initially centered on WAN optimization, a category designed to make applications, data replication, storage traffic, and virtual desktop workloads perform more effectively across geographically dispersed networks. The company later expanded into software-defined wide area networking, or SD-WAN, through its Unity EdgeConnect platform. David Hughes founded Silver Peak in 2004. The company shipped its first product, the NX-series hardware appliance, in September 2005. These appliances were designed to optimize traffic across wide area links and became the foundation of the company’s early product business. Silver Peak subsequently broadened its deployment options with the VX series of virtual appliances and introduced the GMS Global Management System for centrally managing NX and VX installations. The company’s later strategy reflected the movement of enterprise networking away from dedicated hardware and toward software-defined, centrally orchestrated infrastructure. In June 2015, Silver Peak introduced its first SD-WAN solution, EdgeConnect. The platform was subsequently marketed within the Unity family as Unity EdgeConnect, with physical and virtual deployment choices. Related products included Unity Boost, an optional WAN-optimization package, and Unity Orchestrator, a management platform offered as a virtual appliance, cloud-hosted service, or software-as-a-service subscription. Silver Peak built an enterprise ecosystem through partnerships and resale arrangements with major technology companies. Dell resold Silver Peak WAN-optimization products in more than 30 countries for use with Dell storage, networking, server, and virtual desktop environments. Silver Peak also partnered with VMware to make virtual WAN-optimization capabilities available through VMware vCloud Air. EMC resold Silver Peak products through its EMC Select program and qualified them for use with several storage replication and data-protection environments. Hitachi Data Systems likewise resold Silver Peak products for deployment alongside its backup and replication offerings. On July 13, 2020, Hewlett Packard Enterprise announced its intention to acquire Silver Peak for $925 million. The transaction closed on September 21, 2020. Silver Peak then became part of Aruba Networks, an HPE subsidiary, ending Silver Peak’s independent operation as a company. Its technology and product capabilities were incorporated into HPE’s Aruba networking portfolio, particularly the company’s SD-WAN and edge-networking activities.
History
Silver Peak Systems was founded in 2004 by David Hughes as an enterprise networking company specializing in wide area network performance. Its initial market was WAN optimization, where organizations use purpose-built hardware and software to reduce the effects of latency, limited bandwidth, and distance on business applications and data movement. This positioning was relevant to enterprises operating distributed offices, data centers, storage systems, and virtual desktop environments. The company shipped its first product, the NX-series hardware appliance, in September 2005. The NX line formed the company’s early hardware platform for WAN optimization. Silver Peak later added the VX series of virtual appliances, allowing customers to deploy comparable optimization functions in virtualized environments rather than relying exclusively on dedicated physical equipment. To manage these deployments, the company offered the GMS Global Management System for NX and VX appliances. Silver Peak’s product strategy expanded as enterprise networking increasingly adopted virtualization, cloud services, and software-defined control. In June 2015, the company introduced EdgeConnect, its first SD-WAN solution. EdgeConnect represented a move beyond point optimization of WAN traffic toward a broader platform for implementing and managing software-defined connectivity across enterprise locations. The offering was later presented within the Unity product family as Unity EdgeConnect, available in physical and virtual appliance forms. The Unity portfolio also included Unity Boost, an optional WAN-optimization package, and Unity Orchestrator. Orchestrator provided centralized management and was available in several delivery models, including a virtual appliance, a cloud-hosted implementation, and a software-as-a-service subscription. Together, these products reflected Silver Peak’s attempt to combine WAN optimization with centrally controlled SD-WAN operations. Partnerships were an important part of the company’s route to market. Before its acquisition, Silver Peak was a Dell partner for WAN optimization in more than 30 countries. Dell resold the technology for use with storage products such as EqualLogic and Compellent, Force10 networking, servers, and virtual desktop deployments. Silver Peak also partnered with VMware, including an arrangement under which its virtual WAN-optimization products were offered as part of VMware vCloud Air. EMC resold Silver Peak physical and virtual appliances through the EMC Select program. Silver Peak products were also qualified for integration with EMC VPLEX Geo and a range of EMC storage replication, backup, and data-mobility technologies. Hitachi Data Systems similarly resold Silver Peak WAN-optimization products for use alongside its backup and replication products. These relationships connected Silver Peak’s technology with major enterprise storage and infrastructure ecosystems. On July 13, 2020, Hewlett Packard Enterprise announced its intent to acquire Silver Peak for $925 million. The transaction was completed on September 21, 2020. Following completion, Silver Peak became part of Aruba Networks, an HPE subsidiary. The acquisition ended Silver Peak’s existence as an independent company and placed its WAN and SD-WAN capabilities within HPE’s Aruba networking business.
