File Servers
Contents
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[1] 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[2] created for use by the File Server.
An econet real time module was also required, as this was used as a hardware dongle.
