A casestudy by Dell on their MOSS 2007 deployment …

Challenge

The need to collaborate more effectively led business units within Dell to deploy their own instances of the Microsoft®  Office SharePoint®  Server, resulting in a decentralized infrastructure that contributed to higher costs and imperiled important business data

Solution

Dell Services and Dell IT upgraded to centrally managed Microsoft Office SharePoint Server 2007 collaboration software deployed on DellTM  PowerEdgeTM  servers running the Microsoft Windows Server®  2003 Enterprise Edition operating system; to handle data access and storage, Dell IT deployed Microsoft SQL Server on Dell PowerEdge servers, as well as an EMC®  Symmetrix®  SAN and EMC®  Legato®  NetWorker®  SharePoint Portal Server Client Connection software

Benefits

The new collaboration tool set provided by SharePoint 2007 helps employees share knowledge and work together on projects more productively; the centralized SharePoint infrastructure contributes to higher availability, better disaster recovery, and a lower cost of ownership, as well as better security and easier compliance with regulatory requirements
