7840 Extension Switch

The Broadcom 7840 Extension Switch is an enterprise-grade solution engineered to extend and optimize high-performance data center and wide-area storage networks. This switch is ideally suited to environments requiring reliable, low-latency connectivity across geographically dispersed sites, offering exceptional flexibility and speed. Featuring a robust configuration of 24 ports with universal 16 Gb/s Fibre Channel support, the 7840 Extension Switch delivers uncompromised performance for critical storage and business continuity applications. Its advanced network design is further empowered by 1GbE/10GbE Ethernet capabilities for both LAN and WAN connectivity, along with 40GbE support for long-distance, high-bandwidth links. The device leverages end-to-end hardware acceleration, including lossless data transport, adaptive WAN optimization, and secure 256-bit AES encryption, ensuring fast and resilient data mobility. Administrators benefit from sophisticated management and monitoring through Brocade Fabric OS, SANnav, and REST APIs, complemented by innovative features such as Fabric Vision and cut-through routing that maintains deterministic, ultra-low 700 ns latency at 16 Gb/s. Supporting up to 239 switches in a fabric and dynamic WAN bandwidth adjustments, the 7840 ensures seamless scaling and superior enterprise performance from metro to global deployments. With its combination of storage extension, high port density, and advanced Ethernet and Fibre Channel coexistence, this switch is purpose-built for mission-critical applications, data protection, and disaster recovery scenarios across data center, cloud, and hybrid IT infrastructures.
