CHAPTER 1 Features of the PRIMEPOWER Servers
High-performance, Large-capacity Storage Devices
Ultra SCSI disk drives (10,000rpm) can be added (maximum number of drives varies from
model to model).
A CD-ROM drive is provided as standard.
One DAT unit, 8mm tape drive or DLT tape drive can be added as an option (various tape
drives are available, compatibility will vary from model to model).
Reliability, Availability and Serviceability (RAS) Features
ECC or parity protects the data for components and interfaces.
Table 1.1 Data protection method
Components and interfaces Data protection method
Processor
(on-chip & external cache)
ECC (correct 1 bit and detect 2 bits)
Memory ECC (correct 1 bit and detect 2 bits)
Data path ECC (correct 1 bit and detect 2 bits)
Address path Parity
ParityI/O bus (PCI)
Processor operation Monitoring by SCF service processor
Built-in basic SCSI, LAN Parity, IP checksum
Note: ECC or parity does not protect the RS-232C serial interface and floppy disk.
Power-on diagnostics are conducted on system components such as processors and memory.
Automatic System Reconfiguration (ASR) isolates faulty hardware components such as
processors and memory modules immediately after detection.
A SCF (System Control Facility), which has an integrated service processor, monitors the
operation of the SPARC64 GP processors, environmental temperatures, power and fans.
Status of LEDs and messages on the LCD panel indicate the status when an error occurs.
The RCI (Remote Cabinet Interface) allows control over power cycling of expansion I/O units,
such as the Expansion Disk Cabinet and Expansion File Unit Type-2, and monitors for errors.
Internal disk drives are hot-swappable. In addition, redundant power supplies and fans are
supported for high availability. (PRIMEPOWER200 Pedestal Server does not support it.)
Lockable cover panels to prevent unauthorized access to the internal I/O devices. (Rackmount
type server does not support it.)
