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. • Non-volatile random-access memory (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 Fibre Channel-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 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 server • SNMP agent • SMI-S compliant API • Syslog auditing • Reliable Commit Service (RCS) • Network Time Protocol (NTP) • Tasks to manage address assignment, routing, link initialization, fabric initialization, link shutdown, DC04 SAN Director shutdown, and the user interface. 120 HP StorageWorks DC04 SAN Backbone Director Switch Overview
