Storport in Windows Server™ 2003: Improving Manageability and Performance in Hardware RAID and Storage Area Networks
Microsoft Corporation
December 2003
Abstract
The Storport driver, new to Microsoft® Windows Server™ 2003, delivers greater performance in hardware RAID and SAN environments than the preexisting SCSIport driver was capable of delivering.
This white paper begins by explaining the limitations of the original SCSIport driver architecture when used with interconnects for which it was not designed. The paper then details the architectural improvements of the new Storport driver, which has been developed to deliver high throughput and CPU-efficient I/O in high performance environments. This paper will be of interest to OEM hardware and software developers, as well as to customers who are interested in encouraging their storage vendors to support high performance solutions in a Windows environment.
