Sun Microsystems Inc. (NASDAQ:JAVA) today announced it has secured the top spot for tape storage automation revenue for the first half of calendar year 2009, as reported by top analyst firm IDC(1). Powered by Sun's tape storage innovation and the most comprehensive hardware portfolio in the world, Sun saw growth within its installed base as well as with new customers who benefit from these efficient, high-performance storage solutions.

“Tape storage is highly efficient, inexpensive and continues to play an important role in helping enterprise customers store and manage growing amounts of data,” said Jason Schaffer, senior director, Storage Group, Sun Microsystems, Inc. “Sun has once again been recognized as the world leader in high-performance, reliable and affordable midrange and enterprise tape

storage solutions. We'll continue to deliver next-generation tape storage innovation to both our installed base and to new customers.”
