PeerCache™ System Requirements
PeerCache™ hardware requirements primarily depend on the amount of bandwidth and network traffic expected to be handled by the cache server. The configurations below represent recommended baseline setups for standard PeerCache deployments.
For the latest optimized configurations and vendor recommendations, please contact Joltid directly.
Recommended Configuration for 100 Mbps Peak Traffic
The following hardware setup is recommended for installations supporting up to 100 Mbps peak-time traffic:
- Pentium IV Processor – 1GHz
- 500W Redundant Power Supply
- 5 × 72.8GB SCSI Hard Drives
- 1 drive dedicated to OS and system logs
- 4 drives dedicated to cache storage
- 2GB ECC DDR Registered RAM
- 100 Mbps Full-Duplex Ethernet Card
- Additional Cooling Ventilators for thermal stability
Recommended Configuration for 200 Mbps Peak Traffic
For larger deployments supporting up to 200 Mbps peak-time traffic, the following configuration is recommended:
- Dual Pentium IV Processors – 2.4GHz
- 500W Redundant Power Supply
- 12 × 72.8GB SCSI Hard Drives
- 1 drive for OS and log storage
- Remaining drives for cache content storage
- 4GB ECC DDR Registered RAM
- 1Gbps Full-Duplex Ethernet Card
- Enhanced Cooling and Additional Ventilation
Note: Heat management is one of the most critical factors affecting long-term hardware reliability in high-performance cache environments.
Recommended Cache Storage Capacity
The optimal cache storage size depends on:
- Total traffic volume
- User download behavior
- Content popularity patterns
- Network growth expectations
Larger cache sizes generally improve cache hit ratios and increase bandwidth savings. However, organizations should balance storage expansion costs with the long-term return on investment.
Real-world deployment testing is recommended to determine the ideal storage configuration for your network.
