EPYC 7502P Server (256GB/1TB)
- EPYC 7502P Server (256GB/1TB) - Configuration and Overview
This article details the configuration of an AMD EPYC 7502P based server equipped with 256GB of RAM and 1TB of storage. This configuration is commonly used for medium to large-scale MediaWiki installations, offering a balance of performance and cost-effectiveness. This guide is intended for system administrators and those responsible for maintaining the server infrastructure.
Overview
The EPYC 7502P is a 32-core, 64-thread server processor designed for demanding workloads. Paired with ample RAM and fast storage, this server provides a robust foundation for running a high-traffic wiki. Proper configuration is crucial to maximize performance and ensure stability. We will cover the key hardware components and recommended software stack for optimal operation. Understanding server hardware and operating systems is beneficial before proceeding. This configuration supports a significant number of concurrent users.
Hardware Specifications
The following table summarizes the key hardware specifications of the server:
| Component | Specification |
|---|---|
| Processor | AMD EPYC 7502P (32 Cores, 64 Threads) |
| RAM | 256GB DDR4 ECC Registered (typically 3200MHz) |
| Storage | 1TB NVMe SSD (Primary) |
| Network Interface | Dual 10GbE ports |
| RAID Controller | Hardware RAID controller (optional, depending on storage configuration) |
| Power Supply | Redundant 800W Power Supplies |
This configuration provides substantial processing power and memory capacity, suitable for handling large datasets and complex queries. The NVMe SSD ensures fast read/write speeds, crucial for database performance. Consider disk caching to further optimize storage performance.
Software Stack
A typical software stack for this server configuration includes:
- Operating System: CentOS 8 / Rocky Linux 8 / Ubuntu Server 20.04 LTS. These distributions are popular choices for server environments due to their stability and security features.
- Web Server: Apache HTTP Server or Nginx. Both are capable of serving MediaWiki effectively. Nginx is often favored for its resource efficiency.
- Database: MySQL / MariaDB. MariaDB is a popular, open-source drop-in replacement for MySQL, often offering performance improvements.
- PHP: PHP 7.4 or PHP 8.0 (compatible version required by MediaWiki 1.40). Ensure the necessary PHP extensions are installed (see MediaWiki documentation).
- MediaWiki: Version 1.40.
Recommended Configuration Details
The following table outlines recommended configuration settings for the core software components:
| Component | Recommended Settings |
|---|---|
| Apache/Nginx | Configure virtual hosts for MediaWiki, enable mod_rewrite (Apache), tune worker processes. |
| MySQL/MariaDB | Configure `innodb_buffer_pool_size` to approximately 50-70% of available RAM. Optimize query cache settings. Enable slow query logging for performance monitoring. |
| PHP | Increase `memory_limit` to at least 256MB (or higher based on wiki size). Enable opcache for improved performance. Configure timezone correctly. |
| MediaWiki | Configure `$wgMainCacheType` to 'redis' or 'memcached' for improved caching. Set appropriate `$wgUploadDirectory` and `$wgUploadPath`. |
These settings are starting points and may need to be adjusted based on specific workload and wiki size. Regular performance tuning is essential. Consider using a monitoring solution like Prometheus or Grafana to track server resource usage.
Storage Configuration
While a single 1TB NVMe SSD is sufficient for a smaller wiki, larger wikis might benefit from a RAID configuration for redundancy and increased storage capacity.
| RAID Level | Description | Pros | Cons |
|---|---|---|---|
| RAID 1 | Mirroring | Data redundancy, simple implementation | Reduces usable storage capacity by 50% |
| RAID 5 | Striping with parity | Good balance of redundancy and capacity | Requires at least three drives, write performance can be slower |
| RAID 10 | Striping and mirroring | Excellent performance and redundancy | Requires at least four drives, expensive |
The choice of RAID level depends on the specific requirements and budget. Using a hardware RAID controller is generally recommended for improved performance and reliability. Regular data backups are still crucial, regardless of RAID configuration.
Security Considerations
Securing the server is paramount. Implement the following security measures:
- Keep the operating system and all software components up-to-date with the latest security patches.
- Configure a firewall (e.g., `firewalld` or `iptables`) to restrict access to only necessary ports.
- Use strong passwords for all user accounts.
- Enable HTTPS and configure SSL/TLS certificates.
- Regularly review server logs for suspicious activity. See server security for more details.
- Implement intrusion detection and prevention systems.
