dsync+ is a high performance file-copying tool that gets the most out of networks and storage systems.
dsync+ synchronizes directories between sites, that is, given a remote source directory and a local destination directory, dsync+ copies the necessary files in order to make the directories identical.
The chart above shows measurements made by NASA engineers comparing file transfer performance between NASA Ames in California and NASA Goddard in Maryland. The sites were connected by a pair of Longbow E-100s. See the press release for more details about this test.
dsync uses InfiniBand™ and Linux features to minimize CPU and kernel involvement in the data transfer to achieve these results. Now, even more impressive results can be achieved with dsync+, an improved dsync that takes full advantage of multiple paths, if available.
Notes:
- dsync+ runs on Linux only
- for best results, hosts should be connected by InfiniBand
- Longbow InfiniBand range-extenders are ideal for connecting distant InfiniBand fabrics, ensuring full dsync+ performance between sites
- dsync+ is a commercial product available only from Obsidian. To arrange a trial, please contact us.
