File Servers

Acorn Level 1

Consisted of a single machine sharing a DFS diskette.

Acorn Level 2

A level 2 server required a dedicated server machine to serving file requests. The dedicated machine required a 6502 second processor to be fitted.

A level 2 server utilised normal disc drive(s) for storage, although the diskettes had to be formatted to fileserver format using an included utility to be readable by the fileserver.

Each authorised user has a password, this protected a directory on the disk for which the user had owner permissions, these permissions and can protect their files.

Each disc could also contain a library directory where shared information could be stored, with all authorised users having access t o files in the library directory.

Acorn Level 3

The level 3 fileserver added the facility to access a hard disk, the fileserver however also required a second processor.

The hard disk was formatted as a standard ADFS disk, but had an ANFS partion created for use by the File Server.

An econet real time module was also required, as this was used as a hardware dongle.
