Abstract

A disk cache translation system for mapping data record lengths between systems having different data record lengths. Command queue ( ) maps into initiation queue ( ) to allow I/O manager ( ) to manage I/O requests from operating system ( ). I/O requests are statused by I/O manager ( ) using status queue ( ). Store-thru cache ( ) provides a single interface to disk array ( ) such that disk array write operations are reported complete only when user memory ( ), I/O cache ( ) and disk array ( ) are synchronized. Data record length translations are performed using I/O cache ( ) in order to align data record length differences between operating system ( ) and I/O device ( ).
