control processor monitors diagnostics to ensure the system is operational should a failover be

Bus monitoring and control of blades and other field-replaceable units (FRUs).
Serviceability
The device 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 most 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.
Hardware and software watchdog timers.
Status LEDs.
Predictive diagnostics analysis through Fabric Watch.
SNMP (including version 3) integration with higher-layer managers.
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. Some of these applications include:
Name server
Alias server
Zone server
Simple Network Management Protocol (SNMP) agent
SMI-S compliant API
Syslog auditing
Reliable Commit Service (RCS)
NTP
Tasks to manage address assignment, routing, link initialization, fabric initialization, link shutdown,
the device shutdown, and the user interface
