AT&T’s Unix Systems Laboratories has signed up Veritas Software Corp of Santa Clara, California, to develop disk and file management products which will improve support for data intensive applications in Unix System V.4 – also part of the Unix International Road Map. First fruit of the agreement is Veritas’ VxVM Volume Manager virtual disk management system expected by the end of the year – aimed at commercial on-line transaction processing, database management and network application users, which enables Unix to span multiple disks. It includes disk mirroring, disk striping and on-line disk reconfiguration, back-up, performance analysis and tuning. A Unix file system-compatible fast recovery file system, visual administrator and configuration management software will follow in the first quarter of next year. Pyramid Technology, and Sequent Computer Systems have also signed agreements with Veritas, while Intel Corp, NCR Corp, Prime Computer Inc, Wyse Technology Inc and Unisys Corp have chorussed in unison that they will take VxVM.
