AdStar (an acronym for Advanced Storage and Retrieval) was a division of IBM that encompassed all the company's storage products including disk, tape and optical storage systems and storage software.
History
In 1992 IBM combined their Storage Products businesses comprising eleven sites in eight countries into this division.[1] On its creation, AdStar became the largest information storage business in the world. It had a revenue of $6.11 billion, of which $500 million were sales to other manufacturers (OEM sales), and generated a gross profit of about $440 million (before taxes and restructuring).[2]
To provide additional autonomy—thereby further encouraging OEM sales—IBM established AdStar as a wholly owned subsidiary in April 1993, with outsider Ed Zschau as chairman and CEO.[2] To some observers this appeared to be an admission by IBM that the storage subsidiary no longer provided a strategic advantage by providing proprietary devices for its mainframe products,[2]
