TempDB on Shared Disk

If one or more tempdb files are on the same disk as other data files, then access to those other data files can impact tempdb performance.

⚠ Virtual disks may reside on the same physical disks, and opting for multiple small volumes in the cloud could result in fewer IOPS when compared to a single large volume.

Suggested Action

After reviewing the storage layer and technology, consider moving tempdb to a dedicated drive \ LUN to improve the overall performance.
