InfoServer 150 System Overview
1.1 System Highlights
•
Communication ports
A single DEC-423 asynchronous port (with MMJ connector for VT series
terminals) is provided as standard. You can use this port to connect a
terminal to the server to establish a local server management session.
(See Section 2.3.6 and the InfoServer System Operations Guide for more
information). This port is preset to run at 9600 baud, so any terminal
connected to this port must be set at 9600 baud.
•
SCSI connectability
The small computer systems interconnect (SCSI) is an industry standard
for connecting mass storage devices.
•
Add-on storage devices
You can purchase external expansion boxes to provide added storage
capability. These external boxes must be qualified by Digital in order to
meet the system requirements. You can connect up to 12 external drives to
the server, provided you observe SCSI bus length guidelines.
1.2 Storage Devices
The InfoServer 150 system uses the following internal storage devices:
•
RZ23L hard disk (InfoServer 150 system configuration)
•
RZ24 hard disk (InfoServer 150VXT system configuration)
•
RRD42 compact disc drive
Figure 1–1 shows the location of the RRD42 compact disk drive in the system
enclosure.
1.2.1 Internal RZ Hard Disk
The server has one internal RZ drive. After the initial system bootstrap, the
server uses this drive as its primary bootstrap device. For the initial bootstrap,
the server uses the software compact disc supplied with the system.
The server also uses the RZ drive to save server characteristics and network
configuration information for use at subsequent server bootstraps.
1.2.2 RRD42 Compact Disc Drive
A compact disc is an optical, read-only storage media. The InfoServer 150
system comes with one RRD42 compact disc drive. The system can bootstrap
from compact disc, although the internal RZ hard disk drive is the primary
bootstrap device.
You can use the RRD42 drive for many purposes, such as software installation
and database storage.
