General System Requirements
This page outlines the necessary prerequisites for deploying MetaDefender Storage Security (MDSS), covering supported operating systems, system requirements, and specific details for Unix and Windows deployments.
Operating system-specific system requirements are available at:
Prerequisites
Hardware Configurations
Depending on your deployment type, please ensure your hardware meets the following minimum requirements:
Basic Deployment (Minimum System Requirements)
| Hardware | MDSS Dedicated Instance | MDSS + MD Core Shared Instance |
|---|---|---|
| CPU | 16 cores (vCPUs) | 32 cores (vCPUs) |
| RAM | 32 GB | 64 GB |
| Free Disk Space | 200 GB* | 400 GB |
Advanced Deployment (Minimum System Requirements)
For advanced usage, particularly when you intend to process a very large number of files, it is not recommended to run MD Core on the same machine as MDSS.
| Hardware | MDSS Dedicated Instance |
|---|---|
| CPU | 16 cores (vCPUs) |
| RAM | 32 GB |
| Free Disk Space | 200 GB* |
Disk Space Planning (applicable to all deployments)
Careful disk space planning is crucial for the optimal performance and reliability of the MetaDefender Storage Security platform.
Base Installation:
- Core Application: 20 GB
Operational Requirements
- A minimum of 100 GB is recommended for log retention and analysis.
- Space for temporary files created during remediation operations is critical (more details here). The allocation should be calculated based on your largest anticipated file size using the formula:
Minimum temporary space = 2 × (size of largest file in GB)- Example: for an environment where the largest file is 50 GB, you should allocate at least 2 × 50 GB = 100 GB for temporary files.
Total Recommended Allocation:
- For a production environment, the minimum recommended disk space should be calculated as:
Total Disk Space = Base Installation + Logging Data + Temporary Files- Example: For a standard deployment handling files up to 50 GB:
- 20 GB (Base Installation) + 100 GB (Logging) + 100 GB (Temporary Files) = 220 GB
- For a production environment, the minimum recommended disk space should be calculated as:
Note: Insufficient disk space may negatively impact system performance and reliability, particularly during high-volume remediation operations. Regular monitoring of disk usage is strongly advised to ensure optimal system performance.
