The ULTRIX Operating System, Version 4.5 SPD 26.40.32

Diskless Workstations

ULTRIX supports a local area network of diskless work-

stations (clients) managed from a central host equipped

with the necessary mass storage (the server). Central-

izing the workstation’s disk resources reduces the over-

all system cost and simpliﬁes the administration of the

network.

DMS (Diskless Management Service) performs diskless

workstations setup. The DMS is structured to set up

both VAX and RISC workstations from a VAX or RISC

server. To manage a large number of diskless work-

stations, the DMS is capable of installing through a

database ﬁle.

The following conﬁguration guidelines apply to diskless

workstations and servers:

• All the ULTRIX supported VAXstation and Digital

RISC worksystems are supported diskless clients.

• The minimum memory conﬁguration is 6MB for a VAX

diskless client or 8MB for a RISC diskless client.

• The minimum memory is 16MB for a VAX diskless

server or 16MB for a RISC diskless server.

• The MicroVAX 2000, VAXstation 2000, and any

MicroVAX or VAXstation server with an RQDX1,

RQDX2, or RQDX3 disk controller is limited to the

support of three diskless clients.

• If multiple network segments are present, the DMS

clients and server must be on the same segment of

the network.

The minimum hardware requirements for any future ver-

sion of this product may be different from the require-

ments for the current version.

Optional Hardware

Additional memory and/or secondary storage may be

required depending upon the need for ULTRIX software

or optional software products and usage of the ULTRIX

Operating System.

Note: Combinations of hardware options are subject to

limitations such as bandwidth, physical conﬁguration re-

straints, thermal dissipation, and electrical loads/power.
