What are the key differences between the Brocade 7800 16/6 and Brocade 7800 4/2?

Both models of the Brocade 7800 leverage the same hardware and software platform. The Brocade 7800 16/6 Extension Switch is a robust platform for data centers and multi-site environments that are implementing disk and tape solutions for open systems and mainframe environments. The Brocade 7800 4/2 offers lower port density, select advanced features, and a lower price point— making it a cost-effective option for smaller data centers and remote offices that are implementing point-to-point open systems disk replication or mainframe zGM, tape, or Teradata warehousing applications. It does not include support for Open Systems Tape Pipelining. The Brocade 7800 4/2 can be easily upgraded to the Brocade 7800 16/6 through software licensing, providing scalability and investment protection for growing environments.

What optional extension features are available for the Brocade 7840, Brocade 7800, Brocade SX6, and Brocade FX8-24?

What is required to enable the 40 GbE ports on the Brocade 7840 and Brocade SX6?

There is no license required to enable the 40 GbE ports on the Brocade SX6 blade. However, both WAN upgrade optional licenses are needed for the Brocade 7840 Extension Switch to enable the 40 GbE ports.

What is required to enable the 10 GbE ports on the Brocade FX8-24?

The optional 10 GbE ports are easily activated on a per-blade basis through a simple license upgrade to maximize FCIP bandwidth. Activating the 10 GbE ports on each blade doubles the aggregate bandwidth to a maximum of 20 Gbps and enables additional FCIP port configurations (ten 1 GbE ports and one 10 GbE port, or two 10 GbE ports).

What benefits will the new Brocade FX8-24 hardware SKU provide?

Brocade introduced a new Brocade FX8-24 hardware SKU to provide higher platform IPsec throughput. The new Brocade FX8-24 provides 20 Gbps IPsec throughput compared with 10 Gbps IPsec throughput on the original Brocade FX8-24 hardware SKU. No new license is required to enable higher IPsec throughput on the new Brocade FX8-24 hardware SKU. However, Brocade FOS 7.1 is required to enable the higher IPsec throughput. The new Brocade FX8-24 hardware SKU supports all previous Brocade FOS releases that support the current Brocade FX8-24 hardware SKU. When running any previous Brocade FOS release, the new Brocade FX8- 24 hardware SKU is no different than the original Brocade FX8-24 hardware SKU in terms of functionality

What is required to upgrade the Brocade 7800 4/2 to the functionality of the Brocade 7800 16/6?

The Brocade 7800 4/2 can be easily upgraded with a simple license upgrade to increase bandwidth and functionality. The upgrade license activates 12 additional Fibre Channel ports, four additional 1 GbE ports, six additional VE_Ports, and Open Systems Tape Pipelining.

Are Brocade optics required for the new switches?

Yes. The Brocade 7840, Brocade 7800, Brocade SX6, and Brocade FX8-24 require Brocade-branded Small Form-Factor Pluggable (SFP) and Quad Small Form-Factor Pluggable (QSFP) optics.

Does Brocade offer a choice of SFPs?

Yes. The Brocade 7840, Brocade 7800, Brocade SX6, and Brocade FX8-24 can use a variety of Brocade hot-pluggable SFP and SFP+ transceivers to support distance, xWDM, cable type, and port-speed requirements.

Is there a minimum version of Brocade FOS required for the Brocade SX6 Extension Blade?

The Brocade SX6 requires Brocade FOS 8.0.1 or higher.

Is there a minimum version of Brocade FOS required for the Brocade 7840?

Brocade 6510 and 6505 Switches support real-time power measurement, providing insight on power consumption in the fabric.

Is there a minimum version of Brocade FOS required for the Brocade FX8-24 and Brocade 7800?

The Brocade FX8-24 and Brocade 7800 require Brocade FOS 6.3 or higher.

Can I use the Brocade 7840, Brocade 7800, Brocade SX6, and Brocade FX8-24 for Fibre Channel and IP extension?

The Brocade 7840 and Brocade SX6 support both Fibre Channel and IP extension. However, the Brocade 7800 and Brocade FX8- 24 support only Fibre Channel extension.

FCIP Technology

What is FCIP?

FCIP was designed as a simple tunneling protocol to link Fibre Channel over distance on standard IP networks. Used primarily for remote replication, backup, and storage access, FCIP provides Fibre Channel connectivity over IP networks between Fibre Channel devices or fabrics. FCIP leverages special high-speed and Big Data TCP/IP processing, which is essential for storage applications to be reliable and available, and maintain data integrity over long distance. Table 3 outlines how FCIP is designed and used.

  FCIP
Use case Enables replication, backup, and storage access over long distance
Benefit Moves more data faster and further for disaster recovery, data protection, and data mobility solutions

Transport FCIP/TCP/IP/Ethernet
Encapsulation Brocade encapsulates Fibre Channel data sequences into compressed batches. Those batches fill TCP segments to their maximum size and then form IP datagrams.
IP-routable Yes

IP Extension Technology

What is Brocade IP Extension?

Brocade IP Extension technologies help give storage administrators more control over their IP storage flows between data centers. There are five IP extension pillars: performance, operational excellence, enhanced availability, solid security, and easy deployment. IP Extension uses the same VE_Ports and circuits that FCIP uses, or it can use its own.

Brocade IP Extension is used primarily for IP storage applications, such as remote host-based or database-based replication, NAS replication, IP backups, and tape grids. It leverages special high-speed and Big Data TCP/IP processing, which is essential for storage applications to be reliable, available, and maintain data integrity over long distances. Table 4 outlines how Brocade IP Extension is designed and used.

Key advantages include:

  • Brocade IP Extension proxies the local data center TCP sessions. This eliminates all latency effects and provides a clean, stable network that allows the end device to operate at its maximum performance. Brocade WAN-optimized TCP transports the data to the other data center, where another local TCP proxy communicates with the device on the other side.
  • A multitude of IP storage flows is managed in a single tunnel so that the over-bandwidth usage across the WAN can be optimized and made more reliable. There is no way to optimize with rate limiting (or with other methods) a large number of individual autonomous flows across the WAN. Brocade IP Extension manages these individual flows using the TCP rwnd (Receive Window). Very large performance improvements have been demonstrated.
  • The tunnel between data centers is optimized using Adaptive Rate Limiting, QoS, WAN-optimized TCP, and streams. WANoptimized TCP is an aggressive and sophisticated TCP stack that maintains data transport across the most adverse conditions. It can do what individual TCP stacks on end devices cannot do.
  • Brocade provides operational excellence with tools such as Brocade Network Advisor, Monitoring Alerting Policy Suite (MAPS), and the latest versions of Brocade Fabric OS. The system provides Brocade Fabric Vision, Flow Generator, WAN Test Tool (Wtool), Extension Dashboard, and more—all the tools needed to diagnose issues in an extension network. IP networking administrators seldom make these tools available to storage administrators.
  • Brocade IP Extension can transport all IP storage flows encrypted using IPsec. IPsec on the Brocade 7840 is a hardware implementation, which implies two important things: There is very little added latency (5 µs) when performing encryption, and the throughput of encryption is exceptionally fast (line rate).
  • Brocade has taken into account deployment concerns for IP Extension. There is no need to re-cable, change IP subnets, or change VLANs. Only the IP gateway for the subnet(s) located at the remote data center need to be changed to the Software Virtual Interface (SVI) on the Brocade 7840. This SVI acts as the gateway for the IP storage traffic headed across the WAN. The Brocade 7840 provides Link Aggregation (LAG) to the data center LAN switch(es) to which the IP storage is connected. LAG delivers adequate bandwidth and link redundancy for high availability.

What are circuits?

Circuits are the building blocks for trunks. A trunk is a tunnel with more than one circuit. A circuit consists of a source and destination IP address pair and per-QoS TCP connections. An Ethernet port can be assigned one or more circuits. Each circuit automatically creates multiple TCP connections that can be used for QoS prioritization. This is part of PTQ (PerPriority TCP QoS).

What is the impact of circuits on tunnels?

With the development of circuits, a tunnel is no longer bound to a single physical interface or a single connection to a peer Ethernet switch. The Brocade 7840 and 7800 Extension Switches and the Brocade FX8-24 Extension Blade create tunnels that are composed of one or more circuits, enabling Extension Trunking.

What is Extension Trunking and how does it work?

Extension Trunking is an optional licensed feature that enables the creation of logical high-bandwidth tunnels (“trunks”) composed of multiple circuits, and spanning multiple physical ports. Traffic within a trunk is balanced across all circuits to optimize bandwidth and performance. Trunks also overcome physical link failures with redundant paths, Lossless Link Loss (LLL), and guaranteed in-order data delivery.

The number of tunnels is synonymous with the number of VE_Ports. VE_Ports are the endpoints of a tunnel. The Brocade 7840 and Brocade SX6 support up to 20 tunnels in FCIP mode and up to 10 tunnels in hybrid (IP Extension) mode. Up to 20 tunnels are supported on the Brocade FX8-24. Up to eight tunnels are supported on the Brocade 7800. The Brocade FX8-24 provides up to 10 Gbps bandwidth for a single trunk using either 1 GbE ports or the optional 10 GbE ports. The maximum trunk size using the 1 GbE ports is 10 Gbps on the Brocade FX8-24, and 6 Gbps on the Brocade 7800. On the Brocade 7840 and the Brocade SX6, the maximum extension trunk size supported is 20 Gbps, and up to two such trunks can be configured per Brocade 7840 or Brocade SX6 when the maximum WAN rate is enabled.

What is Brocade Adaptive Rate Limiting and how does it work?

Adaptive Rate Limiting is an optional licensed feature on the Brocade 7800 Extension Switch and Brocade FX8-24 Extension Blade, and is included on the Brocade 7840 and Brocade SX6. It dynamically adjusts shared bandwidth between guaranteed minimum rates and available maximum rates for each circuit within a trunk. This overcomes the problem of fixed provisioning of bandwidth, which leads to over-provisioning and underutilization of links. Adaptive Rate Limiting enables applications to exceed guaranteed minimum rates when competing bandwidth dissipates.

What is PTQ (PerPriority TCP QoS) and how does it work?

PTQ extends Brocade Fabric OS QoS across extension links by putting those traffic flows into dedicated WAN-optimized TCP sessions for each priority. The extension blade or switch prioritizes traffic as high, medium, or low on a per-flow basis within a tunnel to optimize bandwidth by application. QoS is enforced only when congestion occurs at egress from the extension blade or switch. FCIP QoS integrates seamlessly with Brocade Fabric OS QoS for consistency throughout the entire fabric. IP Extension QoS operates the same way with the same priorities (high, medium, low) and is separate from FCIP QoS. There are seven priorities altogether: four for FCIP (including class-F) and three for IP Extension.

What is Brocade Integrated Routing (FCR)?

Integrated Routing (FCR) is an optional licensed feature that leverages the latest Brocade ASIC technology to provide Fibre Channel routing on a per-port basis. Because a Fibre Channel E_Port can be made to act as an EX_Port, data can be communicated between fabrics while maintaining remote fabric isolation. Integrated Routing (FCR) eliminates the need for a dedicated router or consumption of chassis slots with special routing blades—thereby reducing cost, complexity, and management overhead.

Mainframe Technology

Does Brocade support mainframe solutions?

Brocade provides as much as 95 percent of the total extension infrastructure used by the mainframe market, which includes FICON, ESCON, and bus and tag equipment for local switching or remote business solutions. With more than 20 years of experience and thousands of customers around the globe, Brocade offers valued products and services to help organizations meet their critical business objectives.

What is FICON?

FICON is an IO protocol used between IBM (and compatible) mainframes and storage arrays. It takes the higher-layer ESCON protocol and maps it into a Layer 2 transport frame. It is mapped into the same physical layer and framing specifications as Fibre Channel but is unique to the FICON protocol. FICON and Fibre Channel protocols can reside within the same switching infrastructure.

What Brocade products support FICON extension solutions?

The Brocade 7840 and 7800 Extension Switches and the Brocade SX6 and FX8-24 Extension Blades provide unique solutions for mainframe storage applications, including FICON disk emulation for IBM z/OS Global Mirror (zGM), also known as XRC (Extended Remote Copy), as well as FICON Tape Pipelining for write and read operations for IBM and Oracle virtual and standalone tape offerings.

What licenses are required for FICON functionality?

For Brocade Fabric OS fabrics, all functional capabilities required to support FICON are included in the base release. Optional FICON features separately licensed for the Brocade 7840 and 7800 Extension Switches and the Brocade FX8-24 Extension Blade include:

  • Brocade Advanced Accelerator for FICON: Enables high-performance FICON tape and zGM replication over distance.
  • Brocade FICON Management Server: Control Unit Port (CUP) enables host control of switches in mainframe environments.

What is CUP (FICON Management Server)?

Control Unit Port (CUP) is an in-band management function that enables mainframe applications to perform configuration, monitoring, management, and statistics collection functions. Several IBM mainframe management applications require CUP functionality on FICON backbones, directors, or switches. The Brocade FICON Management Server license enables CUP functionality.

Do the Brocade 7840, Brocade 7800, Brocade SX6, and Brocade FX8-24 provide ESCON and bus and tag support?

Yes. These products support z/OS host connectivity to ESCON and bus and tag devices via external Optica Prizm (and ESBT) for FICON initiator to ESCON (and bus and tag) target protocol conversion. The solution provides extension for legacy ESCON and bus and tag tape controllers and select printers. ESCON and bus and tag disk are not supported.

What FICON data rates are supported?

Brocade supports FICON at the data rates consistent with industry standards. Host and storage interfaces supported include 1, 2, 4, 8, 16, and 32 Gbps FICON interfaces.

Can FICON be intermixed with open systems?

Yes. Brocade Virtual Fabrics is supported on the Brocade 7840 with Brocade FOS 7.3, the Brocade SX6 with Brocade FOS 8.0.1, and the Brocade 7800 and Brocade FX8-24 through Brocade FOS 7.0 and 7.1, respectively. Brocade Virtual Fabrics allows fabrics that are each configured with specific characteristics for open systems or z/OS environments to share the same platform—and even the same Ethernet interface—enabling consolidation while providing traffic isolation in mixed environments. The Brocade 7840 with Brocade FOS 7.3 or later and the Brocade 7800 with Brocade FOS 7.1 or later support up to four logical switches/two CUP instances. The Brocade SX6 with Brocade FOS 8.0.1 and the Brocade FX8-24 with Brocade FOS 7.0 or later support up to eight logical switches/four CUP instances.

Extension Management

What management tools are available for the Brocade 7840, Brocade 7800, Brocade SX6, and Brocade FX8-24?

Management and administrative operations can be performed through familiar Brocade management tools, including Brocade Network Advisor, Brocade Web Tools, and the Command Line Interface (CLI). Moreover, optional FICON CUP capabilities enable IBM mainframe management applications to seamlessly support Brocade FICON environments (only available in the Enterprise edition of Brocade Network Advisor).

Is Brocade Network Advisor required to manage the Brocade 7840, Brocade 7800, Brocade SX6, and Brocade FX8-24?

No. However, Brocade Network Advisor does include the following enhanced FCIP management capabilities that help simplify and unify management of extension network infrastructures:

  • View health and performance indicators in customizable browser-accessible dashboards, saving administrative time and effort
  • Quickly perform root-cause analysis with point-in-time playback to discover and resolve network issues
  • Provide a comprehensive topology view of all tunnels and trunks across all fabrics discovered by Brocade Network Advisor
  • Simplify tunnel and trunk configuration and management with a wizard interface
  • Drill down through the topology or dashboards to view and configure connection and switch properties

Is there a minimum version of Brocade Network Advisor required for the Brocade 7840 and Brocade SX6 extension products?

Brocade Network Advisor 12.3 or above is required to manage the Brocade 7840. Brocade Network Advisor 14.0.1 or above is required to manage the Brocade SX6.
