Ever wonder about the nitty-gritty details of your SQL Server's underlying hardware? Sometimes, peeking into the Windows Registry can give you some valuable insights. Here are a few handy SQL commands to pull essential hardware information, along with some important considerations for optimizing performance.
Unveiling Storage Driver Parameters
For those running SQL Server on VMware, understanding your storage driver settings is crucial for optimal I/O. You can query the registry to see the current driver parameters for your PVSCSI adapter:
EXEC sys.xp_instance_regread N'HKEY_LOCAL_MACHINE', N'SYSTEM\CurrentControlSet\services\pvscsi\Parameters\Device', N'DriverParameter';VMware suggests specific values for intensive I/O workloads: RequestRingPages=32 and MaxQueueDepth=254. These settings can significantly impact your disk performance.

---Discovering Your BIOS Release Date
Knowing your system's BIOS release date can be useful for troubleshooting or determining if you're running on an up-to-date firmware version. Here's how to retrieve it directly from the Windows Registry:
EXEC sys.xp_instance_regread N'HKEY_LOCAL_MACHINE', N'HARDWARE\DESCRIPTION\System\BIOS', N'BiosReleaseDate';Identifying Your Processor Details
Understanding your server's processor is fundamental to SQL Server performance tuning. You can grab the full processor description from the registry with this command:
EXEC sys.xp_instance_regread N'HKEY_LOCAL_MACHINE', N'HARDWARE\DESCRIPTION\System\CentralProcessor\0', N'ProcessorNameString';For insights into processor selection for SQL Server and how it impacts performance, check out this valuable resource:
