The Lenovo DB720 is built for maximum flexibility, scalability, and ease of use. Organizations can scale from 24 to 64 SFP+ ports in an efficient 1U form factor that delivers industry-leading port density and space utilization.
The DB720S is designed for maximum flexibility and value. 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 ports to 64 ports in an efficient 1U form factor that delivers industry-leading port density and space utilization. This switch also provides easy integration into existing SAN environments — from 8Gb to 64Gb speeds — while introducing the benefits of Gen 7 Fibre Channel connectivity. And the DB720S simplifies deployment, configuration, and management of SAN resources with a collection of easy-to-use tools.
With Lenovo FC SAN switch offerings, Lenovo can be your trusted partner that offers “one stop shop” and single point of contact for delivery of leading edge technologies and innovations from Lenovo and other leading IT vendors. These offerings can satisfy the wide range of your end-to-end IT infrastructure needs, including end-user devices, servers, storage, networking, services, management software, and financing.
The DB720S provides exceptional price/performance value by including standard enterprise class software standard like Fabric Vision®, ISL Trunking, Integrated Routing, and Extended Fabrics.
The ThinkSystem DB720S FC SAN Switch offers the following features and benefits:
To further simplify operations and increase visibility, the DB720S includes Brocade Fabric Vision® technology to monitor and analyze the SAN. This technology provides visibility and insight to quickly identify problems and achieve critical service-level agreements (SLAs).
The DB720S Switch with Fabric Vision technology provides a robust analytics architecture that delivers autonomous SAN technology through self-learning, self-optimizing, and self-healing capabilities. Fabric Vision technology is a suite of features that leverage comprehensive data collection capabilities with powerful analytics to quickly understand the health and performance of the environment and identify any potential impacts or trending problems. The combination of SAN analytics and automation technologies unlocks the capabilities to deliver a self-learning, self-optimizing, and self-healing autonomous SAN.
Features of Fabric Vision include:
Brocade SANnav Management Portal
To streamline management workflows, organizations can leverage the optional subscription-based Brocade SANnav Management Portal software to accelerate the deployment of new applications, switches, servers, and storage. Furthermore, a modernized graphical user interface (GUI) improves operational efficiencies with visual dashboards for instant visibility and faster troubleshooting.
EZSwitchSetup
With EZSwitchSetup, organizations can reduce the number of steps to deploy and configure a switch. In addition, the simplified user interface of Brocade Web Tools makes the SAN easier to manage. For more information, see the EZSwitchSetup User Guide, available from https://docs.broadcom.com/doc/FOS-90x-EZSwitch-UG.
Perfect for high-performance, latency-sensitive workloads
Enterprises are quickly moving their high-performance, latency-sensitive workloads to NVMe flash-based storage. The DB720S Switch supports NVMe over Fibre Channel, enabling organizations to integrate Gen 7 Fibre Channel networks with next-generation flash storage, without a disruptive rip-and-replace. This enables enterprises to achieve faster application response times and harness the performance innovation inherent in NVMe storage. NVMe, combined with the high performance and low latency of Gen 7 Fibre Channel, delivers the performance, application response time, and scalability needed for next-generation data centers.
Access Gateway
The DB720S can be deployed as a full-fabric switch or as an Access Gateway, which simplifies fabric topologies and allows heterogeneous fabric connectivity (the default mode setting is a switch). Access Gateway mode utilizes N_Port ID Virtualization (NPIV) switch standards to present physical and virtual servers directly to the core of SAN fabrics. Access Gateway allows you to configure your fabric to handle additional devices without increasing the number of switch domains. Key benefits of Access Gateway mode include the following:
