Data Domain: Data Domain Again Ranked "Lead In-Plan" Deduplication Vendor Among European Enterprises, and at Top of &
LONDON--(Marketwire - January 12, 2009) - Data Domain, Inc. (
Data Domain was rated highest in both In Pilot and In Near-term plans by storage professionals participating in the study. Over the last three European Storage Studies by TheInfoPro (Waves 9, 10 and 11), Data Domain's In Plan ratings have increased from 5% to over 21%, faster than any other deduplication vendor.
Robert Stevenson, Managing Director of Storage Research for TheInfoPro, said, "Our Wave 11 European Storage Study reflects building momentum for data deduplication adoption plans in Europe, as 'Not in Plan' ratings for the technology fell yet again to just 33%, and 'In Pilot/Evaluation' ratings doubled to 15%. Data Domain's highest 'In Plan' rating and fastest rate of growth in this category over three consecutive European Wave Storage Studies points to increasing traction for the company with European enterprises."
TheInfoPro (TIP) is an independent research network and leading supplier of market intelligence for the Information Technology (IT) industry. TIP's Storage Studies detail technology adoption trends and timeframes, management techniques, and vendor performance data for the Storage industry.
"Data Domain's position as the lead 'In Plan' deduplication vendor spans multiple Wave Storage Studies," said Beth White, vice president of marketing for Data Domain. "We believe we are well positioned to capitalize on the deduplication adoption this study points to in European enterprises."
