Brocade EMC DS-7720B Dell Networking SAN Switch Fibre Channel with best price ​ The Connectrix B-Series 64Gb/s DS-7700B family of Fibre Channel SAN switches support data growth, demanding workloads and data-center consolidation. The Connectrix DS-7730B and DS-7720B platforms are built for maximum flexibility, scalability and ease of use. DS-7730B The Connectrix DS-7730B 64G switch is a high-density building block that enables dense rackmount environments to connect more devices and build larger fabrics. With 128 64G ports in a 2U design, organizations can create high-scale fabrics in less space. The DS-7730B utilizes 96 64G SFP+ ports and 16 2x64G double-density optical transceiver (SFP-DD) ports. Each of the 16 SFP-DD transceivers provides 2 ports, making 32 ports available for device or ISL connectivity. The addition of SFP-DD ports allows the DS7730B to connect more servers, storage, and switches in a small footprint. Built to support maximum flexibility and dense Fibre Channel fabrics, the DS-7730B offers cost-effective, pay-as-you-grow scalability, expanding from 48 ports to 128 ports with Ports on Demand (PoD). The DS-7730B base configuration comes with 48 ports enabled. To scale from 48 ports to 128 ports, additional 24-port SFP+ PODs and a 32-port SFP-DD POD can be installed in any order and combination. In addition, with a 50% latency reduction compared to the previous generation and no oversubscription, the DS-7730B enables maximum performance of NVMe storage and high-transaction workloads. The DS-7730B includes optional features such as Fabric Vision, Extended Fabric, ISL Trunking and Integrated Routing at no additional charge. DS-7720B 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.
