FOR CODING PURPOSES, PLEASE DO NOT EDIT ABOVE THIS LINE.
(this comment will not show on the live version of this page)


Microsoft recently released an update that generates a System Event Log message on systems running Microsoft Windows 7*, Windows Server 2008 R2* or earlier operating systems.
No warning logged when the Storport miniport driver tries to use more than 8 SCSI buses in Windows Server 2008 R2*.

This new System Event Log entry only displays on systems running the following components:

System Event Log message:

This Storport* miniport driver is trying to use more than 8 SCSI buses. This exceeds the supported maximum on this operating system. Please contact your storage controller manufacturer to determine whether this device and driver is designed to work on this operating system.

Note For Intel® Rapid Storage Technology enterprise (Intel® RSTe), buses are the number of SAS ports on the host, whether they are connected or not. One extra bus is allocated for the RAID function, which results in nine, generating the System Event Log message.

Summary:

This Microsoft update is not a result of new Intel® RSTe features or changed functionality. The update is a result of something recently realized by Microsoft that has been in the Intel® RSTe driver architecture since its inception.

There have been no critical errors and only one non-critical error encountered as a result of how the RSTe driver is architected. See the answer to the "What is the reported issue?" question below.

All Intel RSTe drivers are fully validated and have successfully completed Microsoft’s WHQL* testing requirements prior to release.
