SQL Server 2019 Requirements:
the necessary conditions for installing SQL Server 2019 on Windows servers.
Requirements for Hardware:
- The disk space requirements for SQL Server will vary depending on the components you choose when installation, with a minimum of 6GB needed on the drive where SQL is being installed.
- It needs at least 1GB of RAM, although Microsoft advises 4GB, and depending on the size of the database, we might need to increase the RAM for better performance.
- Note that only x64 processors are supported for SQL Server installation. MS no longer provides support for x86.
Requirements for Software:
- Windows Server 2016 or Windows Server 2019 is the minimal operating system requirement for SQL Server 2019.
- It needs the.NET Framework 4.6.1, which Windows Server 2016/Windows Server 2019 will have already installed.
- Additionally, it is preferable to have.NET Framework 3.5 installed because Database Mail needs it.

Page File Configuration:
Servers are configured by setting a pagefile with 1.5 times of memory (1.5*Physical Memory) to obtain a memory dump for upcoming examination.
Disk Volumes Details:
Disk performance must be taken into account for SQL and some applications that exhibit high I/O behavior. Data and log volumes must be on different disks or volumes.
Example:
| Volume | Drive Mount Point | Size in GB | Disk Speed |
| SQL DATA | G:\SQLDATA | 250 GB | FAST |
| SQL LOGS | G:\SQLLOGS | 300GB | VERY FAST |
| SQL TEMP LOG | G:\SQLTEMPLOG | 50GB | VERY FAST |
| SQL TEMP DATA | G:\SQLTEMPDATA | 50GB | FAST |
| SQL BACK | G:\SQLBACK | 500 GB | STANDARD |
Note: Mount point mount points do not inherit from mount point root permissions. These root permissions must be manually copied and set to the mount points.
