White Paper: Scaling SharePoint 2007: Storage Architecture (R2)

The purpose of this whitepaper is three fold. First, this document is intended to provide prescriptive guidance targeted at the storage subsystem for a highly scalable SharePoint implementation in order to facilitate architectural planning. Second, it is intended to provide techniques for monitoring scalability metrics for existing SharePoint implementations. Finally, it provides techniques for modifying storage architecture of SharePoint systems that are suffering from poor performance due to the fact that the I/O burden on the storage subsystem has exceeded its capability.

Many SharePoint instances that are in place today unfortunately "evolved" into production. Often times they exist as the result of an untrained person just clicking "next" through the WSS or MOSS installer application. That said, even an experienced SharePoint Administrator will often fail to get the most out of the farm they are building.
