Sun Enterprise 4000, 5000, and 6000 Systems

The Sun Enterprise 6000 server system, the Sun Enterprise 5000 server system and the Sun Enterprise 4000 server system are available in two enclosures (see Figure 2-2):

• Enterprise 6000 or 5000 is a 56-inch cabinet containing either a 16-slot or 8-slot card cage.

• Enterprise 4000 is a stand-alone enclosure containing an 8-slot card cage.

Figure 2-2 Sun Enterprise 6000 and 5000 Server Cabinet System and Sun Enterprise 4000 Stand-alone System

The same CPU/memory board, I/O boards, disk board, processor modules, memory SIMMs, power modules, and cooling modules are used in all enclosures.

The minimum configuration for the Sun Enterprise 4000, 5000, and 6000 is:

• 16-slot or 8-slot card cage

• Modular power supply

• Fan tray (cabinet servers) or fan box (standalone server)

• Clock board

• CPU/memory board

• I/O board

• Peripheral power supply

• AC distribution unit

• SCSI receptacle for removable media, including CD-ROM

Sun Enterprise systems have extensive error detection mechanisms, and an Automatic System Reconfiguration (ASR) feature that enables the system to be rebooted with failed components (such as CPUs, memory, or I/O) disabled. When an error is detected, the system is reconfigured so that the board containing the failed components is placed in low power mode and is no longer accessible.

The hot-plugable feature inserts a new board into a powered up system, despite being "live," or being supplied with electrical power. Once a working board is added to a powered on system with the hot-plugable feature, the Solaris 2.5.1 or 2.6 software environments will not use the new board until the system is rebooted. The systems also support hot-plugable disk drives and redundant, hot-plugable power and cooling units.

High speed networking is supported by integrated 10 or 100 Mb Ethernet and optional ATM interface.

The systems support remote control administration, which enables remote rebooting and power cycling.

The system monitor for these servers is Solstice(TM) SyMON(TM), a system performance tool that you can use to:

• Monitor the performance of a large server with multiple processors, I/O, and disks.

• Optimize the configuration and throughput of the server.

• Identify hardware and software failures quickly. Failures range from major failures (CPU crash), to minor failures (slow cooling fan). Solstice SyMON identifies the component or software and its location.

• Monitor hardware performance to detect incipient hardware failure (soft read errors on a disk).
