The two-and-a-half year-old partnership for Windows Powered NAS products will now also include joint training of engineers and aligned sales and marketing teams.
Sales partners will also get access to implementation blueprints and case studies.
"We strengthen the relationship with HP to bring Windows Powered NAS deeper into the enterprise," said Zane Adam, director of product management and marketing at Microsoft's Enterprise Storage division.
HP and Microsoft hope to reduce the number of servers they run, but at the same time add storage hardware. This will be a multibillion-dollar market opportunity within the HP customer base alone.
"There are nearly two million NT 4 and Windows 2000 servers out there in need of consolidation, almost 1.2 million of those are in the HP base. We will target those," Adam said.
There are also about 500,000 Exchange 5.0 and older messaging servers in use that are up for consolidation.
These systems are up for replacement because they run old software and are complete servers now in use as file or e-mail storage. Replacing the systems with fewer servers, but added storage hardware, will result in reduced cost as there is less hardware involved and the system is easier and cheaper to manage.
