HP DC04 SAN Director Switch Hardware Reference Guide

• Dual CP Blades that enable hot, nondisruptive, fast firmware upgrades
• Each CP Blade contains one serial port and two Ethernet ports, for management and for
service.
• Standby CP Blade to monitor diagnostics to ensure it is operational, in case a failover is
required.
• Offline CP Blade diagnostics and remote diagnostics to simplify troubleshooting
• Bus monitoring and control of blades and other FRUs
Serviceability
The DC04 SAN Director provides the following features to enhance and ensure serviceability:
• Modular design with hot-swappable components
• Flash memory that stores two firmware images per CP Blade
• USB port on CP blades for all tasks that formerly required an FTP/SCP server, including
software and firmware upgrades
• Redesigned cable management using vertical fingers to accommodate the horizontal orientation
of the blades
• NVRAM, containing the serial number, 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
Software features
The Fabric OS allows any FC-compliant device to attach to the switches as long as it conforms to
the device login, name service, and related FC standards. Each operating environment requires
that an FC 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 server
• SNMP agent
• SMI-S compliant API
• Syslog auditing
• RCS
• NTP
• Tasks to manage address assignment, routing, link initialization, fabric initialization, link
shutdown, DC04 SAN Director shutdown, and the user interface.
