High-Speed Data Transfer Guide
With years of hands-on experience working with research teams, KREONET has optimized data transfer performance for a wide range of scientific projects. Core tuning guides and best practices are openly shared through the KREONET Wiki to promote reproducible, high-throughput data ment.
This guide recommends separating research compute clusters from dedicated Data Transfer Nodes (DTNs) to maximize performance. It outlines key considerations for deploying a DTN, including:
- Kernel Tuning: Optimizing Linux network parameters for high-speed data transfers.
- Transfer Tools: Introduction to open-source tools optimized for high-throughput, such as HPN-SSH and GridFTP..
- Benchmark Results: Sharing real-world performance benchmarks on specific hardware configurations.
Science DMZ
In networking, a DMZ refers to a network segment that allows only trusted systems and operates without inline security appliances. A Science DMZ is a purpose-built network architecture designed to maximize data transfer performance by minimizing intermediary devices and limiting the use of traditional security mechanisms. It enables only essential, high-performance systems to operate within the environment, ensuring the fastest and most efficient ment of scientific data.
How to Request Technical Support
If you are experiencing unusual network performance, we recommend first reviewing the following documentation for self-diagnosis and resolution. These are the same resources used by the KREONET team when troubleshooting:
* High-Speed Data Transfer Guide (wiki.kreonet.net/faster-data)
* KREONET Wiki: (wiki.kreonet.net)
For technical support related to Science DMZ design or advanced data transfer optimization, please contact the KREONET Operations Center to schedule a consultation.
