Overview:

The Connectrix DS-7720B Switch is a 64-port, ultra-dense 1U switch designed to build highperformance fabrics that maximize flash and NVMe storage to meet demanding workloads. Delivering unmatched 64G performance and 50% lower latency compared to the previous generation, this switch delivers a fixed-port building block designed to maximize the performance of flash and NVMe environments to meet demanding workloads. This enterprise-class switch offers pay-as-you-grow scalability with Ports on Demand (PoD). Organizations can quickly, easily, and cost-effectively scale from 24 to 64 ports. The DS7720B provides up to 56 64G SFP+ ports and 8 2x64G double-density SFP-DD ports, all in an efficient 1U package. Each SFP-DD transceiver provides 2 ports, making 16 ports available for device or ISL connectivity. The Connectrix DS-7720B base configuration comes with 24 ports enabled and can scale to 56 ports with SFP+ transceivers only or 64 ports by installing SFP+ and SFP-DD POD licenses in any order and any combination. Each SFP-DD port can accommodate SFP+ or SFP-DD transceivers, providing the flexibility to use either type of transceiver in those ports when needed. The DS-7720B switch is fully licensed, meaning software features such as Fabric Vision, Extended Fabric, ISL Trunking, Integrated Routing and FICON CUP are included at no additional charge. The DS-7720B is certified for mainframe environments.
