Data Transfer Tools
The goal of this section is to help you maximize your wide-area network bulk data transfer performance by using file transfer tools that are designed to maximize network throughput. A number of tools are described below.
Sample Results: disk-to-disk testing from Berkeley, CA to Argonne, IL (near Chicago). RTT = 53 ms, network capacity = 10Gbps, RAID = 4 disks, RAID Level-0. Note that to get more than 1 Gbps (125 MB/s) disk to disk requires RAID.
|scp||140 Mbps (17.5 MB/s)|
|HPN patched scp, 1 disk||760 Mbps (95 MB/s)|
|HPN patched scp, RAID disk||1.2 Gbps (150 MB/s)|
|Globus, 1 stream, 1 disk||760 Mbps (95 MB/s)|
|Globus, 1 stream, RAID disk||1.4 Gbps (175 MB/s)|
|Globus, 4 streams, RAID disk||5.4 Gbps (675 MB/s)|
|Globus, 8 streams, RAID disk||6.6 Gbps (825 MB/s)|
