RFC 122 Simple-Minded file System April 1971

I. Preface

UCSB will provide file storage for Network users. UCSB's Simple Minded File System (SMFS) is addressed as socket number X'401', site 3. No accounting parameters are required. This document is intended to provide programmers with the information necessary to communicate with SMFS which conducts all Network transactions trough its NCP which operates under the Host-Host protocol of August 3, 1970.*

II. Implementation

The following information is not essential to use of SMFS but may be of interest. SMFS will store user's files on IBM 2316 disk packs, each with 29M 8-bit bytes of storage capacity. UCSB has two 2314 units, each with eight drives on-line. Initially, one drive will be allocated for Network storage, and the appropriate pack will always be mounted an that drive, and hence accessible to SMFS without operator intervention. UCSB estimates that for the next year it will have up to four drives that it can devote to Network use. The second, third, and fourth drives will be allocated only as the need arises. SMFS is written to accommodate any number of on-line drives without modification.

If necessary, UCSB will investigate the possibility of making one of the four drives a come-and-go drive on which one of a number of packs ...
