The Ultimate Preinstallation Checklist for SQL Server (On-Premise, Non-Clustered Windows Setup)
A Simple, Practical, and Beginner-Friendly Guide to Getting It Right the First Time
Introduction: Why Preinstallation Matters More Than You Think
Installing SQL Server might seem as simple as clicking “Next → Next → Finish.” But in reality, most SQL Server performance issues, security gaps, and failures originate before installation even begins.
Think of preinstallation like preparing the foundation of a house. If the foundation is weak, everything built on top becomes unstable.
This guide will walk you through a complete preinstallation checklist for SQL Server on-premise in a non-clustered Windows environment, using simple explanations and real-world logic. Whether you're a beginner or someone brushing up your skills, this will help you avoid costly mistakes.
What Is SQL Server Preinstallation?
Before installing Microsoft SQL Server, preinstallation means preparing your system, environment, and infrastructure so the installation:
Runs smoothly
Performs optimally
Remains secure
Scales efficiently
Section 1: Hardware Requirements Checklist
1.1 CPU (Processor)
Checklist:
Minimum: 2 cores
Recommended: 4+ cores
Best Practice: Use modern processors (Intel Xeon / AMD EPYC)
Why it matters:
SQL Server is CPU-intensive. Queries, indexing, and data processing rely heavily on CPU performance.
1.2 Memory (RAM)
Checklist:
Minimum: 4 GB
Recommended: 16 GB or higher
Enterprise workloads: 32 GB+
Golden Rule:
More RAM = better caching = faster queries
1.3 Disk Storage
Checklist:
Separate disks for:
OS
Data files (.mdf)
Log files (.ldf)
TempDB
Use SSDs for best performance
Format with NTFS
Why it matters:
Disk I/O is often the biggest bottleneck in SQL Server.
1.4 Disk Configuration Best Practices
Use RAID:
RAID 1 for logs
RAID 5/10 for data
Avoid using the same drive for everything
Section 2: Operating System Requirements
2.1 Supported Windows Versions
Checklist:
Windows Server 2016, 2019, or 2022
Windows 10/11 (for development only)
2.2 Windows Updates
Checklist:
Install latest patches
Reboot before installation
Why it matters:
Prevents compatibility issues and security vulnerabilities.
2.3 Required Windows Features
Enable:
.NET Framework (version depends on SQL version)
Windows Installer
PowerShell
Section 3: Network Configuration Checklist
3.1 IP Address Setup
Use static IP address
Avoid DHCP for servers
3.2 Ports Configuration
Default SQL Server port:
TCP 1433
Checklist:
Ensure port is open in firewall
Configure SQL Server to use fixed port
3.3 Firewall Settings
Allow:
SQL Server Database Engine
SQL Browser Service (if needed)
3.4 DNS and Hostname
Ensure proper hostname resolution
Avoid renaming server after installation
Section 4: Security & Account Preparation
4.1 Service Accounts
Create dedicated accounts for:
SQL Server Engine
SQL Agent
Reporting Services (if used)
Best Practices:
Use domain accounts
Avoid Local System account
4.2 Permissions Checklist
Grant “Log on as a service”
Minimum required privileges only
4.3 Authentication Mode Decision
Choose between:
Windows Authentication (recommended)
Mixed Mode (if SQL logins needed)
Section 5: Storage & File Layout Planning
5.1 Directory Structure
Plan folders like:
C:\SQLServer\
├── Data\
├── Logs\
├── TempDB\
└── Backups\
5.2 TempDB Configuration Planning
Multiple data files (1 per CPU core up to 8)
Separate disk if possible
5.3 File Growth Settings
Avoid auto-growth in small increments
Use fixed sizes (e.g., 512MB or 1GB)
Section 6: SQL Server Version & Edition Selection
6.1 Choose SQL Server Version
Popular choices:
SQL Server 2019
SQL Server 2022
6.2 Choose Edition
Express (free, limited)
Standard (most businesses)
Enterprise (large-scale systems)
6.3 Compatibility Considerations
Application compatibility
Legacy systems
Vendor requirements
Section 7: Preinstallation Validation Checks
7.1 Run System Configuration Checker
SQL Server setup includes a built-in tool:
Detects missing prerequisites
Identifies conflicts
7.2 Disk Space Verification
Ensure:
Enough space for installation
Future growth capacity
7.3 Pending Reboots
Check:
No pending Windows restart
Section 8: Connectivity & Remote Access Planning
8.1 Remote Desktop (RDP)
Enable RDP access
Secure with strong credentials
8.2 SQL Server Management Tools
Plan installation of:
SQL Server Management Studio (SSMS)
Section 9: Performance Optimization Planning
9.1 Max Server Memory Setting
Leave memory for OS (e.g., 4GB)
9.2 Max Degree of Parallelism (MAXDOP)
Set based on CPU cores
9.3 Cost Threshold for Parallelism
Default is 5 → increase to 50 (recommended)
Section 10: Backup & Recovery Planning
10.1 Backup Strategy
Plan:
Full backups
Differential backups
Transaction log backups
10.2 Recovery Model
Choose:
Simple
Full
Bulk-logged
Section 11: Documentation Checklist
Document Everything:
Server specs
Configuration decisions
Installed features
Service accounts
Section 12: Tools & Utilities Preparation
Install or prepare:
SQL Server Installation Media
Latest cumulative updates
Monitoring tools
Section 13: Common Mistakes to Avoid
❌ Installing everything on C: drive
❌ Using default settings blindly
❌ Ignoring TempDB configuration
❌ Not planning backups
❌ Using weak security accounts
Section 14: A Simple Mental Model
Think of SQL Server preinstallation like preparing a kitchen:
Hardware = stove & fridge
OS = kitchen space
Storage = cabinets
Security = locks
Network = delivery system
If everything is ready → cooking (installation) becomes easy.
Section 15: Step-by-Step Preinstallation Checklist (Quick Summary)
✔️ Hardware
CPU, RAM, Disk configured
✔️ OS
Supported Windows installed
Updates applied
✔️ Network
Static IP
Ports open
✔️ Security
Service accounts created
✔️ Storage
Drives separated
✔️ SQL Version
Selected and downloaded
✔️ Validation
No pending reboots
Conclusion: Build It Right Before You Install It
Installing SQL Server is easy.
Installing it correctly is what makes the difference.
By following this checklist:
You avoid performance bottlenecks
You reduce downtime
You improve security
You make future maintenance easier
