Brocade 6505 Switch
12- and 24-Port 16 Gbps Fibre Channel Entry-Level SAN Switch

Features:

Exceptional Price/Performance for Growing SAN Workloads

The Brocade 6505 combines market-leading throughput with an affordable switch form factor, making it ideal for growing SAN workloads. The 24 ports produce an aggregate 384 Gbps full-duplex throughput; any eight ports can be trunked for 128 Gbps Inter-Switch Links (ISLs). Exchange-based Dynamic Path Selection (DPS) optimizes fabric-wide performance and load balancing by automatically routing data to the most efficient and available path in the fabric. It augments Brocade ISL Trunking to provide more effective load balancing in certain configurations.

In addition, the Brocade 6505 provides a low Total Cost of Ownership (TCO) thanks to a 12-port base configuration, easy administration, 1U footprint, and low-energy consumption—0.22 watts per Gbps and 3.3 watts per port. Enterprise-class capabilities combined with a low TCO yield 40 percent higher performance compared to 10 Gigabit Ethernet (GbE) alternatives at a similar cost.

Industry-Leading Technology That Is Flexible, Simple, and Easy to Use

The Brocade 6505 delivers industry-leading SAN technology within a flexible, simple, and easy-to-use solution. The base configuration includes 12 ports, with up to 24 ports on demand. In addition to providing best-in-class scalability, the Brocade 6505 is easy to deploy with the Brocade EZSwitchSetup wizard and the new “D_Port” feature, which simplifies setup.

A Building Block for Virtualized, Private Cloud Storage

The Brocade 6505 provides a critical building block for today’s highly virtualized, private cloud storage environments. It simplifies server virtualization and Virtual Desktop Infrastructure (VDI) management while meeting the high-throughput demands of Solid State Disks (SSDs). The Brocade 6505 also supports multi-tenancy in cloud environments through Quality of Service (QoS) and fabric-based zoning features.

Brocade Access Gateway Mode

The Brocade 6505 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). 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 Access Gateway transparent to the SAN fabric, greatly reducing management of the network edge. The Brocade 6505 in Access Gateway mode* can connect servers to NPIV-enabled Brocade B-Series, Brocade M-Series, and other SAN fabrics.

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

• 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

  • Flow Monitor: Provides comprehensive visibility into flows within the fabric, including the ability to automatically learn flows and nondisruptively monitor flow performance. Administrators can monitor all flows from a specific host to multiple targets/LUNs, from multiple hosts to a specific target/LUN, or across a specific ISL. Additionally, they can perform LUN-level monitoring of specific frame types to identify resource contention or congestion that is impacting application performance.
  • Flow Generator: Provides a builtin traffic generator for pre-testing and validating the data center infrastructure—including route verification and integrity of optics, cables, ports, back-end connections, and ISLs—for robustness before deploying applications.
• Forward Error Correction (FEC): Enables recovery from bit errors in 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 5 Fibre Channel management and helps users 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. Customizable dashboards graphically display performance and health indicators out of the box, including all data captured using Brocade Fabric Vision technology. To accelerate troubleshooting, administrators can use dashboard playback to quickly review past events and identify problems in the fabric.

What is MAPS?

Brocade Monitoring and Alerting Policy Suite, or MAPS, is a new, 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-ofpolicy conditions, to help administrators quickly pinpoint potential issues and easily identify trends and other behaviors occurring on a switch or fabric

What is Flow Vision?

The Brocade Flow Vision tool suite allows administrators to identify, monitor, and analyze specific application and data flows in order to maximize performance, avoid congestion, and optimize resources. Flow Vision includes:

• Flow Learning: Enables administrators to non-disruptively discover all flows that travel to or from a specific host or storage port or traverse ISLs/IFLs, and monitor fabric-wide application performance. In addition, administrators can discover top and bottom bandwidth-consuming devices and manage capacity planning.
• Flow Monitoring: Provides comprehensive visibility into flows in the fabric, including the ability to automatically learn (discover) flows and non-disruptively monitor flow performance. Users can monitor all flows from a specific host to multiple targets/LUNs or from multiple hosts to a specific target/LUN; monitor all flows across a specific ISL; or perform LUN-level monitoring of specific frame types to identify resource contention or congestion that is impacting application performance.
• Flow Generator: Provides a built-in traffic generator for pre-testing and validating the SAN infrastructure, including internal connections within a switch, for robustness before deploying applications—without requiring 16 Gbps hosts, targets, or external traffic generators.
• Flow Mirroring: Provides the ability to non-disruptively create copies of specific application and data flows, or frame types, for in-depth analysis

What is Fabric Performance Impact (FPI) monitoring?

FPI monitoring automatically detects and alerts administrators to severe levels or transient spikes of latency, and identifies slow drain devices that could impact the network. This feature uses advanced monitoring capabilities and intuitive MAPS dashboard reporting to indicate various latency severity levels, pinpointing which devices are causing or are impacted by a bottlenecked port. This feature also provides automatic mitigation or recovery from the effects of slow drain devices.

FPI 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.

What is integrated metro connectivity?

Brocade 6520 and 6510 Switches support integrated SAN extension over native Fibre Channel (metro connections up to 100 km) for replication and backup over distance. Native Fibre Channel connections now include in-flight compression and encryption as well as optional support for 10 Gbps Fibre Channel over Dense Wavelength Division Multiplexing (DWDM) and dark fiber. To take advantage of the 10 Gbps Fibre Channel support, organizations need a software license and 10 Gbps optics.

How many ports can be configured on the Brocade 6520 and 6510 for 10 Gbps Fibre Channel support?

On both the Brocade 6520 and 6510 with Brocade FOS 7.1, the first eight ports can be configured to operate at 10 Gbps Fibre Channel for data center connectivity over DWDM. With Brocade FOS 7.2, all Fibre Channel ports on the Brocade 6520 and 6510 can be configured to operate at 10 Gbps Fibre Channel.

What are the benefits of in-flight compression over Inter-Switch Links (ISLs)?

In-flight compression optimizes network performance within the data center and over long-distance links. Data is compressed at the source and uncompressed at the destination. Performance varies by data type, but Brocade uses an efficient algorithm to generally achieve 2:1 compression with minimal impact on performance. Compression can be used in conjunction with in-flight encryption. In-flight compression is available only on Gen 5 Fibre Channel port blades.

What are the benefits of in-flight encryption over ISLs?

In-flight encryption minimizes the risk of unauthorized access for traffic within the data center and over long-distance links. It is switch-to-switch encryption, not device or data-at-rest encryption. Data is encrypted at the source and decrypted at the destination. Encryption and decryption are performed in hardware using the AES-GCM-256 algorithm, minimizing any impact on performance. Encryption can be used in conjunction with in-flight compression. In-flight encryption is available only on Brocade 6520 and 6510 Switches and Brocade DCX 8510 Backbone Gen 5 Fibre Channel port blades, and is complementary to data-at-rest encryption provided by the Brocade Encryption Switch and the Brocade FS8-18 Encryption Blade.

How many ports can be configured on Brocade 6520 and 6510 Switches for in-flight compression and encryption?

For in-flight compression and encryption, the following can be configured:

• Up to sixteen ports at 8 Gbps and up to eight ports at 16 Gbps per Brocade
• 6520 Switch
• Up to four ports at 8 Gbps and up to two ports at 16 Gbps per Brocade 6510 Switch

No license is required for this feature.

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 Condor3 switching ASIC compare to previous generations?

The Condor3 ASIC is the industry’s most powerful and efficient switching technology. In addition to Gen 5 Fibre Channel 16 Gbps speed, it includes more bandwidth (768 Gbps), faster I/O performance (420 million frames switched per second), more functionality (including D_Port, in-flight encryption and compression, and Forward Error Correction [FEC]), and higher energy efficiency (less than 1 watt/Gbps).

Brocade 6520, 6510, and 6505 Hardware

Can an existing 8 Gbps Brocade switch be upgraded to 16 Gbps functionality?

No. An 8 Gbps switch will not support 16 Gbps capabilities.

What types of encryption are available?

There are generally two approaches to encryption: data-at-rest and data-in-flight. Data-at-rest encryption encrypts the data so that it is stored on the destination disk or tape in an encrypted form. Data-in-flight encryption (Brocade 6520 and 6510 only) encrypts data as it travels between two points in a network. Data is encrypted as it leaves a source port and decrypted as it arrives at the destination port. Technologies that provide encryption for data-in-flight include IPSec and MACsec (802.1AE) for Ethernet, and FCSP for Fibre Channel. Data-at-rest and data-in-flight encryption are complementary technologies that serve different purposes, and each may be required in order to achieve regulatory compliance.

Are Brocade Small Form-Factor Pluggables (SFPs) required for the Gen 5 Fibre Channel switches?

Yes. Brocade 6520, 6510, and 6505 Switches require Brocade-branded SFPs.

Why do Brocade 6520, 6510, and 6505 Switches require Brocade SFP optics?

This provides quality control that in turn avoids application downtime. The greater the port speed—especially 16 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 16 Gbps?

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

Link Distance with Speed and Fiber Type (meters)

Transceiver Type	Form Factor	Speed	Multi-Mode Max Distance				Single Mode Max Distance
			OM1	OM2	OM3	OM4	9 μm

Brocade 6520, 6510, and 6505 Switches support EZSwitchSetup for intuitive “plug-and-play” deployment.

What is Brocade Access Gateway mode?

Brocade Access Gateway mode can make a switch appear transparent to hosts or the network fabric. With a switch configured in Access Gateway mode, F_Ports connect to the fabric as N_Ports rather than E_Ports. This allows more hosts (and VMs) to access the fabric without increasing the number of switches—thereby simplifying configuration and reducing the number of Domain IDs to manage. Access Gateway enhancements include Brocade Frame-based Trunking, QoS, ClearLink Diagnostic Ports (D_Ports), FEC, and interoperability with multivendor fabrics. Refer to Brocade FOS release notes for additional Access Gateway enhancements.

Brocade 6510, 6505, 5100, and 300 Switches, as well as Brocade 50xx and 40xx Blade Server Switches support Access Gateway mode. Brocade Access Gateway mode is not supported on the Brocade 6520.

Do I need a license to utilize Brocade Virtual Fabrics features?

No. Brocade Virtual Fabrics capabilities for the Brocade 6520 and 6510 Switches are included as part of the base Brocade FOS software (not supported on the Brocade 6505).

Brocade 6510 Mainframe Support

What do mainframe environments gain by using Brocade 6510 Switches?

Brocade 6510 Switches provide significant value for System z environments, including:

• Users can immediately capitalize on 16 Gbps connectivity for System z. The Brocade 6510 Switch delivers 48 ports at full 16 Gbps speed without oversubscription.
• At 0.14 watt/Gbps, the Brocade 6510 Switch frees up limited power and cooling resources to support more mainframe and storage equipment.
• Brocade Virtual Fabrics capabilities allow data centers supporting both open systems and System z to logically partition a switch and SAN fabric into Fibre Channel and FICON environments. This enables the data center to reduce network infrastructure costs and improve return on investments, while keeping Fibre Channel and FICON management and traffic flows separate.
• For data replication and backup over distance, the combination of Brocade 6510 and Brocade 7800 Extension Switches provides powerful extension capabilities that include disk-write acceleration over extended Fibre Channel and FCIP links (called Fast Write), FICON Tape Pipelining to accelerate tape reads and writes, and FICON Global Mirror Disk Emulation to accelerate disk reads when using IBM Global Mirror.
• Brocade Top Talkers and Adaptive Networking capabilities help optimize FICON environments and application service levels.

Can a single Brocade 6510 Switch with mixed FICON and Fibre Channel traffic use CUP to manage the system?

If CUP is used to manage the FICON environment, all FICON and Fibre Channel ports are visible and can be managed using CUP. If an organization is using Brocade Virtual Fabrics and “Logical Switch,” CUP can be used to manage only those ports in the partition to which it is defined.

Can I manage a FICON fabric with Brocade DCFM and Brocade Network Advisor?

Brocade Data Center Fabric Manager (DCFM) 10.4.1 supports only 8 Gbps Brocade DCX platforms and switches. Brocade Network Advisor 11.1.2 and above supports the entire Brocade DCX 8510, Brocade DCX, and Brocade switch product families, and is required for managing the Gen 5 Fibre Channel platforms in FICON environments.
