The Brocade G620 delivers increased performance for growing and dynamic workloads through a combination of market-leading throughput and low latency across 32 Gbps and 128 Gbps links. With Gen 6 ASIC technology providing up to 566 million frames switched per second, the Brocade G620 Switch shatters application performance barriers with up to 100 million IOPS to meet the demands of flash-based storage workloads. At the same time, port-to-port latency is minimized to 900 nanoseconds through the use of cut-through switching at 32 Gbps. With 48 SFP+ ports and 4 Q-Flex ports, each providing four 32 Gbps connections, the Brocade G620 can scale up to 64 device ports for an aggregate throughput of 2 Tbps. Moreover, each Q-Flex port is capable of 128 Gbps parallel Fibre Channel for device or ISL connectivity, enabling administrators to consolidate and simplify cabling infrastructure.

Administrators can achieve optimal bandwidth utilization, high availability, and load balancing by combining up to eight ISLs in a 256 Gbps framed-based trunk. This can be achieved through eight individual 32 Gbps SFP+ ports or two 4×32 Gbps QSFP ports. Moreover, exchange-based Dynamic Path Selection (DPS) optimizes fabric-wide performance and load balancing by automatically routing data to the most efficient, available path in the fabric. This augments Brocade ISL Trunking to provide more effective load balancing in certain configurations.

Simplify Scalability and Management Complexity

The Brocade G620 features up to 64 Fibre Channel ports in an efficiently designed 1U form factor, delivering industry-leading port density and space utilization for simplified scalability and data center consolidation.

Simplified Management and Robust Network Analytics

Brocade Fabric Vision technology provides a breakthrough hardware and software solution that helps simplify monitoring, maximize network availability, and dramatically reduce costs. Featuring innovative monitoring, management, and diagnostic capabilities, Fabric Vision technology enables administrators to avoid problems before they impact operations, helping their organizations meet SLAs. Fabric Vision technology includes:

  • IO Insight: Proactively and nonintrusively monitors storage device IO performance and behavior through integrated network sensors at the storage tier, providing deep insight into problems and ensuring service levels.
  • Monitoring and Alerting Policy Suite (MAPS): Leverages prebuilt, rule-/ policy-based templates within MAPS to simplify fabric-wide threshold configuration, monitoring, and alerting. Administrators can configure the entire fabric (or multiple fabrics) at one time using common rules and policies, or customize policies for specific ports or switch elements. In addition, administrators can include IO Insight metrics in MAPS policies to be notified of performance degradation.
  • Fabric Performance Impact (FPI) Monitoring: Leverages predefined MAPS policies to automatically detect and alert administrators to different latency severity levels, and to identify slow drain devices that could impact network performance. This feature identifies various latency severity levels, pinpointing exactly which devices are causing or are impacted by a bottlenecked port, and quarantines slow drain devices automatically to prevent buffer credit starvation.
  • Dashboards: Provides integrated dashboards that display an overall SAN health view, along with details on out-ofrange conditions, to help administrators easily identify trends and quickly pinpoint issues occurring on a switch or in a fabric.
  • Configuration and Operational Monitoring Policy Automation Services Suite (COMPASS): Simplifies deployment, safeguards consistency, and increases operational efficiencies of larger environments with automated switch and fabric configuration services. Administrators can configure a template or adopt an existing configuration to seamlessly deploy a configuration across the fabric. In addition, they can ensure settings do not drift over time with COMPASS configuration and policy violation monitoring within Brocade Network Advisor dashboards.
  • Brocade ClearLink Diagnostics: Ensures optical and signal integrity for Fibre Channel optics and cables, simplifying deployment and support of high-performance fabrics. ClearLink Diagnostic Port (D_Port) is an advanced capability of Fibre Channel platforms.
  • Flow Vision: Enables administrators to identify, monitor, and analyze specific application flows in order to simplify troubleshooting, maximize performance, avoid congestion, and optimize resources. Flow Vision includes:
    • Flow Monitor: Provides comprehensive visibility, automatically learns, and non-disruptively monitors flow performance. Administrators can monitor all flows from a specific host to multiple targets or LUNs, from multiple hosts to a specific target/LUN, or across a specific ISL. Additionally, they can perform LUNlevel monitoring of specific frame types to identify resource contention or congestion that is impacting application performance. With IO Insight capability, administrators can monitor first IO response time, IO completion time, number of pending IOs, and IOPS metrics for a flow from a specific host to a target or LUN.
    • Flow Learning: Enables administrators to non-disruptively discover all flows that go to or come from a specific host port or a storage port, or traverse ISLs/IFLs or FCIP tunnels to monitor fabric-wide application performance. In addition, administrators can discover top and bottom bandwidth-consuming devices and manage capacity planning.
    • Flow Generator: Provides a built-in traffic generator for pretesting and validating the data center infrastructure for robustness—including route verification and integrity of optics, cables, ports, back-end connections, and ISLs—before deploying applications.
    • Flow Mirroring: Provides the ability to non-disruptively create copies of specific application and data flows or frame types that can be captured for in-depth analysis.
  • Forward Error Correction (FEC): Enables recovery from bit errors in device connections and ISLs, enhancing transmission reliability and performance.
  • Credit Loss Recovery: Helps overcome performance degradation and congestion due to buffer credit loss.

Brocade Network Advisor

Brocade Network Advisor simplifies Gen 6 Fibre Channel management and helps organizations proactively diagnose and resolve issues to maximize uptime, increase operational efficiency, and reduce costs. The wizard-driven interface dramatically reduces deployment and configuration times by allowing fabrics, switches, and ports to be managed as groups.

A Building Block for Virtualized, Private Cloud Storage

The Brocade G620 provides a critical building block for today’s highly virtualized and cloud environments. It both simplifies server virtualization and meets the high-throughput demands of Solid State Disks (SSDs). The Brocade G620 also supports multitenancy in cloud environments through Virtual Fabrics, Quality of Service (QoS), and fabric-based zoning features. In addition, it provides efficient link utilization with up to 64 Gbps of in-flight data compression over ISLs. Organizations can have up to four ports at 16 Gbps of in-flight data compression per Brocade G620 Switch. Furthermore, internal fault-tolerant and enterprise-class RAS features help minimize downtime to support mission-critical cloud environments.

Brocade Access Gateway Mode

The Brocade G620 can be deployed as a full-fabric switch or as a Brocade Access Gateway, which simplifies fabric topologies and heterogeneous fabric connectivity (the default mode setting is a switch). Brocade Access Gateway mode utilizes N_Port ID Virtualization (NPIV) switch standards to present physical and virtual servers directly to the core of SAN fabrics. This makes it transparent to the SAN fabric, greatly reducing management of the network edge. The Brocade G620 in Brocade Access Gateway mode can connect servers to NPIV-enabled Brocade B-Series, or other SAN fabrics.

Organizations can easily enable Brocade Access Gateway mode via Brocade Network Advisor or a CLI. Key benefits of Brocade Access Gateway mode include:

  • Improved scalability for large or rapidly growing server and virtual server environments
  • Reduced management of the network edge, since Brocade 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

Features

What are QSFP ports and why did Brocade decide to use them on the Brocade G620 Switch?

To reduce investment costs, energy consumption, and cabling requirements, the Brocade G620 Switch uses a space-efficient, four-channel Quad Small Form-Factor Pluggable (QSFP) optic that enables high-density port configurations as well as improved serviceability and ease of use. These QSFPs retain all of the performance and functionality of the standard SFP+ while supporting individual, per-port LED indicators for easy troubleshooting and diagnostics.

QSFP modules increase port density three to four times more than SFP+ modules and reduce the number of cables per switch from 64 to 16, significantly reducing cable management challenges. The QSFP form factor has been widely deployed across the networking industry for Ethernet and Fibre Channel (4×16 Gbps Brocade UltraScale Inter-Chassis Links) connectivity, making cabling options readily available.

Can I order and use a Q-Flex port PoD without purchasing an SFP+ port PoD?

Brocade Fabric Vision technology provides a breakthrough hardware and software solution that helps simplify monitoring, maximize network availability, and dramatically reduce costs. Featuring innovative monitoring, management, and diagnostic capabilities, Fabric Vision technology enables administrators to avoid problems before they impact operations, helping their organizations meet SLAs.

What is IO Insight?

IO Insight is built-in instrumentation within the Brocade G620 Switch that helps organizations achieve greater control and insight to quickly identify root cause at the storage tier, reducing time to resolution so critical SLAs can be met. The IO Insight capability non-intrusively gathers IO statistics, which can be used within an intuitive, policy-based monitoring and alerting suite to configure thresholds and alarms. In-band device latency and IOPS monitoring detects degraded storage performance, allowing administrators to proactively optimize performance and availability to ensure maximum performance. Additional features include:

  • Provides proactive, non-intrusive, real-time monitoring and alerting with visibility into storage IO health and performance
  • Monitors individual storage devices to gain deeper insights into the performance of the network to maintain SLA compliance
  • Obtains IO latency and IOPS metrics for a storage device in order to diagnose IO operational issues

What is Brocade ClearLink Diagnostics?

The Brocade ClearLink Diagnostics tool leverages Brocade ClearLink Diagnostic Port (D_Port) mode to ensure optical and signal integrity for Fibre Channel optics and cables, simplifying deployment and support of high-performance fabrics. By proactively verifying the integrity of critical transceivers, organizations can quickly address any physical layer issues without the need for special optical testers.

ClearLink Diagnostics allows users to automate a battery of tests to measure and validate latency and distance across the switch links, as well as to verify the integrity of the fiber and optical transceivers in the fabric—prior to deployment or when there are suspected physical layer issues. With ClearLink Diagnostics, only the ports attached to the link being tested need to go offline, leaving the rest of the ports to operate online.

In addition to switch-to-switch link validation, ClearLink Diagnostics also provides the following:

  • Dynamic ClearLink Diagnostics support between Gen 5 and Gen 6 Fibre Channel switches, QLogic, and Emulex fabric adapters when running at 16 Gbps or 32 Gbps, allowing administrators to initiate tests from the adapter
  • The ability to configure settings to ensure consistency and automatically run D_Port tests based on port or switch events, including links over xWDM
  • D_Port pre-provisioning to improve operational control and avoid costly mistakes
  • D_Port integration into MAPS for threshold-based monitoring and alerting
  • Port LED for a visual indication of D_Port test result failures
  • Link power (dB) loss information with D_Port test results

Through collaboration with industry partners, Brocade will extend ClearLink Diagnostics to additional end devices and adapters, providing end-to-end physical layer diagnostics and validation.

What is MAPS?

Brocade Monitoring and Alerting Policy Suite, or MAPS, is an easy-to-use, policy-based threshold monitoring and alerting suite that proactively monitors the health and performance of the SAN infrastructure to ensure application uptime and availability. By leveraging pre-built, pre-validated, rule-/policy-based templates, MAPS takes the guesswork out of defining appropriate rules and actions, simplifying threshold configuration, monitoring, and alerting. With MAPS, organizations can apply thresholds and alerts via a simple two-step process:

  1. Define all host ports, storage ports, and E_Ports that belong to a specific group, or use the pre-defined default groups.
  2. Go to the list of pre-defined policies (each with more than 250 highly tuned rules) and select one to apply to that group, or create a custom policy.

Organizations can configure an entire fabric (or multiple fabrics) at one time using common rules and policies, or customize rules for specific ports—all through a single dialog. The integrated dashboard displays a switch health report, along with details on out-of-policy conditions, to help administrators quickly pinpoint potential issues and easily identify trends and other behaviors occurring on a switch or fabric. In addition, administrators can include IO Insight metrics in MAPS policies in order to be notified of performance degradation.

What is Fabric Performance Impact (FPI) monitoring?

FPI monitoring leverages pre-defined MAPS policies to automatically detect and alert administrators to different latency severity levels, and identifies slow drain devices that could impact network performance. This feature uses advanced monitoring capabilities and intuitive MAPS dashboard reporting to indicate various latency severity levels, pinpointing exactly which devices are causing or are impacted by a bottlenecked port, and quarantining slow drain devices automatically to prevent buffer credit starvation.

FPI monitoring is an invaluable tool for SAN administrators, helping them to avoid problems that can impact application performance. At the same time, it provides Brocade users with capabilities not offered by third-party tools.

How can Dynamic Fabric Provisioning simplify server deployment?

Dynamic Fabric Provisioning (DFP) allows organizations to eliminate fabric reconfiguration when adding or replacing servers through the virtualization of host World Wide Names (WWNs). It combines Brocade switch and adapter technology to reduce or eliminate the need to modify zoning or Logical Unit Number (LUN) masking. In addition, DFP enables pre-provisioning of virtual WWNs, helping organizations eliminate time-consuming steps when deploying new equipment or moving devices within a switch. DFP currently requires Brocade adapters in the host.

How does the Gen 6 switching ASIC compare to previous generations?

The Gen 6 ASIC is the industry’s most powerful and efficient switching technology. In addition to Gen 6 Fibre Channel 32 Gbps speed and 128 Gbps speed, it includes more bandwidth (2 Tbps), faster IO performance (566 million frames switched per second), more functionality (including D_Port and Forward Error Correction [FEC]), and higher energy efficiency (just 0.1 watt/Gbps).

What power management features are included?

The Brocade G620 supports real-time power measurement, providing insight into power consumption in the fabric.

Brocade G620 Hardware

Can an existing 16 Gbps Brocade switch be upgraded to 32 Gbps functionality?

No. An existing 16 Gbps switch will not support 32 Gbps capabilities.

Are Brocade Small Form-Factor Pluggables (SFPs) and QSFPs required for the Gen 6 Fibre Channel switches?

Yes. The Brocade G620 requires Brocade-branded SFPs and QSFPs.

Why does the Brocade G620 Switch require Brocade SFP optics?

This provides quality control that in turn avoids application downtime. The greater the port speed—especially 32 Gbps—the less tolerance that switches have for out-of-spec wavelengths, which can lead to port failure and application interruption

Are supported cable distances affected by 32 Gbps?

Yes. Supported distances are reduced as Fibre Channel speed increases. See the table below.
