Brocade DCX-4S features
The Brocade DCX-4S is part of Brocade's industry-leading Backbone-class product line, a highly robust
class of network switching platform that combines breakthrough performance, scalability, and energy
efficiency with long-term investment. Supporting open systems and System z, DCX Backbones are
designed to address the data growth and application demands of evolving enterprise data centers,
achieve server, SAN, and data center consolidation, and reduce infrastructure and administrative costs.
Key features of the Brocade DCX-4S include:
• Up to 256 external ports in a single chassis, enabling high density SAN configurations with reduced
footprint.
• Support for 1, 2, 4, and 8 Gbps auto-sensing Fibre Channel ports. Trunking technology groups up to
eight ports to create high performance 64-Gbps ISL trunks between switches (10 Gbps ports
(FC10-6) are 10 Gbps only).
• Support for all of the application, port blade, and control processor (CP) blades supported in the
Brocade DCX Backbone (with the exception of the Brocade DCX Core Switch Blade), thereby
providing flexible system configurations and fewer types of new blades.
• Up to 768 ports in one rack can connect with the use of inter-chassis links (ICLs).
• Support for high-performance port blades running at 1, 2, 4, 8, or 10 Gbps, enabling flexible system
configuration.
• Redundant and hot-swappable CP8 and CR4S-8 blades, power supplies, blower assemblies, and
WWN cards that enable a high availability platform and enable nondisruptive software upgrades for
mission-critical SAN applications.
• Universal ports that self-configure as E_Ports, F_Ports, FL_Ports, EX_Ports and M_Ports (mirror
ports). 10 Gbps ports (FC10-6 blade) are E_Ports only.
• Data cryptographic (encryption/decryption) and data compression capabilities through the Brocade
FS8-18 Encryption Blade.
• Fibre Channel over IP (FCIP) functionality through the FX8-24 blade.
• Fibre Channel over Ethernet (FCoE) capability through the FCOE10-24 blade.

Hardware components
The Brocade DCX-4S features a modular and scalable mechanical construction that allows a wide
range of flexibility in installation, fabric design, and maintenance. The chassis can be mounted with the
cables facing the front of the equipment rack or to the rear, and consists of the following:
• Up to four hot-swappable port blade assemblies that can be configured in a single chassis,
delivering up to 256 Fibre Channel ports.
• Two slots for control processor blades (CP8):
‐A single active CP8 blade can control all 256 ports in the chassis.
‐The standby CP8 blade assumes control of the Brocade DCX-4S if the active CP fails.
• Two slots for core switch blades (CR4S-8):
‐CR4S-8 blade interconnects all port blades.
‐Two inter-chassis link (ICL) connectors per blade connect to another chassis.
‐Both CR4S-8 blades are active.
• Modular hot-swappable port blades:
‐16-port, 8-Gbps blades (FC8-16).
‐32-port, 8-Gbps blades (FC8-32).
‐48-port, 8-Gbps blades (FC8-48).
‐64-port, 8-Gbps blades (FC8-64)
• Modular hot-swappable application blades:
‐FX8-24: 24-port (12 FC, 10 GbE, 2 10GbE) FCIP extension blade enabling long distance
communication over existing IP infrastructure.
‐FCOE10-24: 24-port (24 10GbE) CEE-based FCoE blade enabling enhanced connectivity using
existing Ethernet infrastructure. This blade cannot be used in the same chassis as the high
density port blade FC8-64 or any of the other application blades (FX8-24, or FS8-18).
• Modular hot-swappable encryption blades:
‐FS8-18: 16-port, up to 4 blades per chassis, supporting data cryptographic (encryption/
decryption) and data-compression capabilities.
NOTE
If the any of the following blades are used 220 VAC is required:FS8-18, FX8-24, FCOE10-24.
• Modular hot-swappable field replaceable units (FRUs):
‐Two blower assemblies.
‐Two 100 to 240 VAC (auto-sensing) power supplies. 240 VAC is recommended for efficiency and
high availability.
‐Redundant AC primary power connections to ensure high availability. Each power supply has
its own connector.
‐Two WWN cards.
‐Small Form-factor Pluggable (SFP, SFP+, and mSFP) optical transceivers. SFP transceivers
support speeds of 1, 2, and 4 Gbps. SFP+ and mSFP transceivers support speeds of 2, 4, and 8
Gbps.
‐Extended Form-factor Pluggable (XFP) optical transceivers (10-Gbps).
NOTE
The 8-Gbps SFPs and mSFPs autonegotiate at 2, 4, and 8 Gbps. The 4-Gbps SFPs autonegotiate
at 1, 2, and 4 Gbps.

• Automatic control processor failover.
• Nondisruptive "hot" software code loads and activation.
High availability
18 Brocade DCX-4S Backbone Hardware Installation Guide
53-1001191-15

• Easy configuration, save, and restore.
• Hot-swappable World Wide Name (WWN) cards.
The high-availability software architecture of the Brocade DCX-4S provides a common framework for all
applications that reside on the system, allowing global and local states to be maintained through any
component failure. High-availability elements consist of the High Availability Manager, the heartbeat, the
fault/health framework, the replicated database, initialization, and software upgrade.
The High Availability Manager controls access to the standby control processor, facilitates software
upgrades, prevents extraneous switchover activity, closes and flushes streams, provides flow control
and message buffering, and supports a centralized active and standby state.
Reliability
The Brocade DCX-4S uses the following error detection and correction mechanisms to ensure reliability
of data:
• Error Detection and Fault Isolation (EDFI) mechanism, which checks for encoder errors and fault
isolation, such as cyclic redundancy checking (CRC), parity checking, checksum, and illegal address
checking.
• Power-on self-test (POST).
• Dual control processors that enable hot, nondisruptive fast firmware upgrades.
• One serial port and two Ethernet ports (on each control processor) for management and for service.
Offline control processor diagnostics and remote diagnostics simplify troubleshooting. The standby
control processor monitors diagnostics to ensure it is operational, should a failover be necessary.
• Bus monitoring and control of blades and other field-replaceable units (FRUs).
Serviceability
The Brocade DCX-4S provides the following features to enhance and ensure serviceability:
• Modular design with hot-swappable components
• Flash memory that stores two firmware images per control processor
• USB port on control processor blades for all tasks that formerly required an FTP/SCP server,
including software and firmware upgrades
• Nonvolatile random-access memory (NVRAM), containing the OEM serial number, Brocade serial
number, revision information, and part number information
• Background health-check daemon
• Memory scrubber, self test, and bus ping to determine if a bus is not functioning
• RASlog messages
• SMI-S compliant
• Watchdog timers
• Status LEDs

• Predictive diagnostics analysis through Fabric Watch
• SNMP (including version 3) integration with higher-layer managers
• Redesigned cable management using vertical fingers to accommodate the horizontal orientation of
the blades
Software features
The Fabric OS allows any Fibre Channel-compliant device to attach to the switches as long as it
conforms to the device login, name service, and related Fibre Channel standards. Each operating
environment requires that a Fibre Channel host bus adapter (HBA) be available with a standards-
compliant driver for correct interface to the fabric.
Fabric OS consists of a set of embedded applications running on top of an embedded Linux operating
system kernel. These applications include:
• Name server
• Alias server
• Zone serve
• Simple Network Management Protocol (SNMP) agent
• SMI-S compliant API
• Syslog auditing
• RCS (Reliable Commit Service)
• NTP
• Tasks to manage address assignment, routing, link initialization, fabric initialization, link shutdown,
Brocade DCX-4S shutdown, and the user interface
Security
The following table highlights some of the key security features available for the Brocade DCX-4S and
for other Brocade enterprise-class products running Fabric OS 5.2.0 or later. For details, contact your
Brocade DCX-4S supplier and refer to the Brocade White Paper, "The Growing Need for Security in
Storage Area Networks".
