    Description

    The Lenovo ThinkSystem #DB630S is a 2U Gen 6 FC SAN switch offering 96 SFP+ and 8 QSFP+ ports that auto-sense 4/8/10/16/32 Gbps, with Q-Flex trunking up to 128 Gbps for inter-switch links. It scales from 48 to 128 ports via Ports On Demand licensing, delivering non-blocking architecture for hyper-scale and NVMe environments Lenovo Press.

    The #DB620S is a 1U sibling that provides 48 SFP+ and 4 QSFP+ ports in Gen 6 FC, supporting full-fabric or Access Gateway modes with pay-as-you-grow scalability from 24 to 64 ports. EZSwitchSetup and Fabric Vision telemetry streamline deployment and diagnostics in cloud- and virtualization-oriented data centers Lenovo Press.

    For entry-level deployments, the #DB610S offers 24 SFP+ ports, scaling to 24–64 ports with Ports On Demand, and supports 4/8/16/32 Gbps speeds. Its compact 1U design and Fabric Vision capabilities make it ideal for smaller SAN fabrics and edge-storage nodes Lenovo Press.

    At the pinnacle, the #DB720S director switches utilize Brocade X7 Gen 7 ASICs in 8U (256 ports) and 14U (512 ports) chassis, auto-sensing up to 64 Gbps speeds with full backward compatibility. These directors deliver up to 39.6 Tbps non-blocking bandwidth and support future NVMe-over-FC fabrics Lenovo.

    Key Features

    • Gen 6 Fibre Channel: 32 Gbps auto-sensing on SFP+ ports for DB63x/DB62x/DB61x series Lenovo Press

    • Gen 7 Directors: 32–64 Gbps on DB720S via X7-4/8 ASICs, up to 512 ports

    • Ports On Demand: Scale ports in software increments—DB630S (48→128), DB620S (24→64), DB610S (8→24)

    • Q-Flex Trunking: Q-Flex ports bundle four 32 Gbps links into a 128 Gbps ISL channel on Gen 6 models

    • Fabric Vision Telemetry: Embedded diagnostics, VM Insight, I/O Insight for proactive SAN management

    • EZSwitchSetup: Wizard-based initial configuration for rapid, consistent deployments Lenovo Press

    • Brocade Reliability: Redundant power supplies, cooling modules, and control processors for 99.999% availability

    • NVMe-Ready: Seamless transition to NVMe-over-Fabrics with ultra-low latency Lenovo

    Compatibility

    All DB Series switches are PICMG 3.x compliant, interoperating with multi-vendor SAN fabrics (Dell EMC, HPE, IBM) via standard FC protocols. They integrate with Lenovo XClarity, Brocade Fabric OS, and leading management tools (Cisco MDS, Hitachi Fabric Manager), and support Redfish and RESTful APIs for automation with Ansible and ServiceNow Lenovo Press.

    Usage Scenarios

    1. Hyper-Scale Data Centers: Use #DB630S in 2U top-of-rack for high-density server virtualization and NVMe pools.

    2. Enterprise Core Fabrics: Deploy #DB720S directors as spine switches for multi-site private clouds requiring massive port counts.

    3. Edge/Branch SANs: Choose #DB610S or #DB620S for compact, low-cost SANs in ROBO or mid-tier storage clusters.

    Frequently Asked Questions (FAQs)

    Q1: How does Ports On Demand work?
    A1: Ports On Demand (PoD) is a software license that unlocks additional physical ports in predefined increments without hardware changes. For example, DB630S scales from 48 to 128 ports via PoD licenses Lenovo.

    Q2: Can these switches support NVMe-over-Fabrics?
    A2: Yes, Gen 6 and Gen 7 DB Series switches are NVMe-ready, providing low-latency switching and in-flight compression for NVMe FC workloads Lenovo.

    Q3: What management interfaces are available?
    A3: All models support Brocade Fabric OS CLI, GUI, RESTful API (Redfish), and integration with Lenovo XClarity, Ansible modules, and ServiceNow. EZSwitchSetup simplifies initial configuration Lenovo Press.

    Q4: Are these switches backward compatible?
    A4: Yes – they auto-sense and support speeds from 4 Gbps up to their maximum (32 Gbps Gen 6 or 64 Gbps Gen 7), ensuring seamless interoperability with existing FC hardware Lenovo.
