Key features

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:

  • Provides high scalability in an ultra-dense, 1U switch with up to 56 ports, providing up to 64 connections with the use of SFP-DD transceivers, to support high-density server virtualization, cloud architectures, and flash-based storage environments.
  • Increases scalability by using SFP-DD transceivers that provide dual SN connections that allow organizations to connect more servers, storage, or switches in a small footprint. Each transceiver supports two independent connections of 64G Fibre Channel via a two-lane electrical interface.
  • Accelerates critical workloads with 64Gb/s links
  • Maximizes performance of NVMe storage with 50% lower switching latency than Gen 6

  • Provides cyber-resiliency with integrated security technology that protects mission-critical operations by validating the integrity of Gen 7 hardware and software.
  • Guarantees critical application performance by automatically prioritizing traffic and avoiding congestion with Brocade Traffic optimizer.
  • Simplifies troubleshooting by identifying and isolating issues
  • Collects comprehensive telemetry data across the fabric to enable powerful analytics
  • Visualizes the data to easily understand the health and performance of the SAN
  • Automates repetitive tasks to save time and eliminate human error
  • Protects existing device investments with auto-sensing 8, 16 and 32 Gbit/sec capabilities and native operation with any Brocade SAN fabrics.
  • Leverages Fabric Vision technology’s powerful monitoring, management, and diagnostic tools to simplify administration, increase uptime, and reduce costs.
  • Supplies a rich set of standard features at no extra cost, including fabric services, advanced zoning, adaptive networking, full fabric and access gateway operations, integrated 10 Gb FC, and diagnostic tools.
  • Expands fabric capabilities with optional licensed functions, including trunking, advanced monitoring and alerting, long-distance fabrics, and FC-FC routing.
  • Compresses in-flight data on up to four ports for more efficient link utilization.
  • Maximizes resiliency with redundant hot-swap power supplies.
  • Accelerates troubleshooting with built-in advanced diagnostics tools featuring ClearLink Diagnostics with D_Ports (Diagnostic Ports) and select adapters from QLogic and Emulex, which helps ensure optical and signal integrity for 32/64 Gb Fibre Channel optics and cables.

Brocade Fabric Vision

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:

  • Self-learning
    • Gather and transform billions of data points into network intelligence
    • Visualize application and device-based performance and health metrics
    • Detect abnormal traffic behaviors and degraded performance
    • Eliminate operational steps by automatically learning application flows
  • Self-optimizing
    • Optimize critical application performance by automatically prioritizing traffic
    • Guarantee application performance by proactively monitoring and actively shaping traffic
    • Eliminate human errors and performance impacts through open DevOps automation technology
    • Optimize administrative resources with cloud-like SAN orchestration
  • Self-healing
    • Instantly notify end devices of congestion for automatic resolution
    • Ensure data delivery with automatic failover from physical or congestion issues
    • Detect and automatically reconfigure out-of-compliance fabrics
    • Eliminate performance impacts by automatically taking corrective action on misbehaving devices

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:

  • Improved scalability for large or rapidly growing server and virtual server environments
  • Reduced management of the network edge, since Access Gateway does not have a domain identity and appears transparent to the core fabric
  • Support for heterogeneous SAN configurations without reduced functionality for server connectivity
