Background
Recently we ran into a performance issue and wanted to compare our in-house environment against the Vendor’s Original implementation environment.
Is it Storage?
From what we observed our query was eating up a lot of tempdb storage and so quickly zeroed in how tempdb is configured.
Configuration of Tempdb
- Does the number of tempdb files match the number of processor cores
- Are the tempdb files sized equally and do they have the same growth pattern
- Is Instant File Initialization ( IFI ) enabled for the service account that SQL is running under
Hardware Itself
The other concern is whether our hardware has the neccesary IOPS
What type of Storage
And, so bring ups the question what type of storage do we have?
- Is it Local Disk
- Mechanic rotating disk
- SSD
- Is it Network Storage
- Are we running SAN
- Do we have sufficient memory ( PAM )
Self
Wanted to document the steps that needs to be taken by the vendor to document their storage.
And, so tried to try things out on my laptop as I prepared those steps.

The Device name “NVMe CX2-8B256-Q11 NV SCSI Disk Device” does not tell me whether it is an SSD Drive or not.
Let us google on the device name and we found matches
