Lenovo ThinkSystem DB620S 32Gb FC SAN Switch

Product Guide

The Lenovo ThinkSystem DB620S FC SAN Switch provides exceptional price/performance value by

delivering market-leading 32 Gb Gen 6 Fibre Channel technology and combining flexibility, simplicity, and

enterprise-class functionality that supports highly virtualized environments to meet the demands of hyper-

scale, private cloud storage, and growing flash-based storage environments.

Designed to enable maximum flexibility and reliability, the ThinkSystem DB620S is a compact, 1U rack-

mount FC switch that offers low-cost access to industry-leading Storage Area Network (SAN) technology

while providing “pay-as-you-grow” scalability to meet the needs of an evolving storage environment.

The DB620S FC SAN Switch offers 48x SFP+ ports that support 4/8/10/16/32 Gbps speeds and 4x QSFP+

ports that support 128 Gbps (4x 32 Gbps) or 4x 4/8/16/32 Gbps speeds. The DB620S FC SAN switch

provides easy integration into the existing SAN environments while realizing the benefits of Gen 6 Fibre

Channel connectivity, and the switch offers a rich set of standard features with the options to expand its

capabilities as needed.

The DB620S FC SAN Switch can be configured in Access Gateway Mode to simplify deployment. The

switch provides full non-blocking performance with Ports On Demand scalability to support SAN expansion

and enable long-term investment protection.

Key features

The ThinkSystem DB620S FC SAN Switch offers the following features and benefits:

Provides high scalability in an ultra-dense, 1U switch with 48 SFP+ ports and 4 QSFP+ ports (each

QSFP+ port has 4x 32 Gb FC links for 128 Gb FC connectivity between the DB620S FC SAN

switches, or it can be broken out to four links to 4/8/16/32 Gbps SWL optics in a server HBA,

storage device, or another FC switch, for a total of up to 64 connections) to support high-density

server virtualization, cloud architectures, and flash-based storage environments.

Increases performance for demanding workloads with support for 128 Gbps (4x 32 Gbps) and

32 Gbps FC links.

Simplifies end-to-end management by automating repetitive daily management tasks.

Enables “pay-as-you-grow” scalability from single-switch fabric to full-fabric enterprise capabilities

with Ports On Demand scalability.

Optimizes fabric behavior and ensure sufficient bandwidth for mission-critical applications with

advanced traffic management capabilities and adaptive networking.

Provides proactive, non-intrusive, real-time monitoring and alerting of VM and storage I/O health and

performance with VM Insight and IO Insight through integrated network sensors.

Leverages predefined MAPS policies to automatically identify and isolate devices that cause network

performance issues.

Offers dual functionality as either a full-fabric SAN switch or as an NPIV-enabled Access Gateway

(requires 48 SFP+ ports be licensed) that enhances fabric scalability and simplifies management.

Protects existing device investments with auto-sensing 4, 8, 16, and 32 Gbit/sec capabilities and

native operation with Brocade fabrics.

Runs Fabric OS, which delivers distributed intelligence throughout the network and enables a wide

range of value-added features.

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.

Virtualizes physical FC SAN switches and fabrics into logical entities for better flexibility, utilization,

management, and efficiency.

Allows organizations to seamlessly integrate Gen 6 Fibre Channel networks with the next generation

of flash storage – NVMe over Fibre Channel – by being NVMe-ready, without a disruptive rip and

replace, to achieve faster application response times and harness the performance of solid state

drives for better scalability across virtual data centers with flash storage.

Maximizes resiliency with redundant hot-swap power supplies.

Accelerates troubleshooting with built-in advanced diagnostics tools featuring ClearLink Diagnostics

with D_Ports and select adapters from QLogic and Emulex, which helps ensure optical and signal

integrity for 16 Gb and 32 Gb Fibre Channel optics and cables.
