SUMMARY
This article describes the SQL Server Net-Libraries support for the QLogic card. This support is included in Microsoft Data Access Components (MDAC) 2.7 SP1 Refresh (2.7 SP1a).



MORE INFORMATION
The SQL Server Net-Libraries have been changed to add support for the QLogic card. The support that is added for the QLogic card is to sustain SQL Server with the new technologies, especially on 64-bit platforms.

The added support for the QLogic card enables a significant improvement in TPC-C benchmark (TPC-C benchmark is a popular measure for comparing Online Transaction Processing (OLTP) performance on various hardware and software configurations) on the new Itanium processor systems.

Additionally, while you use QLogic support feature, you may get the high scalability for Service Advertising Protocol (SAP) Applications that are running on 64-bit computers. SAP applications already have high scalability on 32-bit computers.

The QLogic support feature is also necessary for handling the processor workloads of Independent Software Vendor (ISV) Applications such as SAP, Siebel, PeopleSoft and JDE that are running on both 32-bit and 64-bit computers. With QLogic support feature, you may gain the ISV workloads between 15-30%.

The added support for the QLogic card does not change the existing SQL Server Net-Libraries support for ServerNetII or cLAN Networks.
