The Public Test Grid

How To Connect To The Public Test Grid

The test grid is subject to being updated at random times, so compatibility is likely to break without notice. Also note that many upgrades require all files and directories to be flushed, especially as storage formats change.

The test grid is currently running an 0.8.0-compatible release (currently 0.7.0-352). Note that this is incompatible with the previous 0.7.0 release).

After installing the code according to ​docs/install.html, copy the following file into its base directory:

file name	file contents
introducer.furl	pb://todjw7qkb4dgq4fkeo7cqydcu5vneioh@tahoecs2.allmydata.com:52106/introducer

Then run tahoe start.

We created a shared public directory: feel free to use it for experimentation -- once your node is up and running on port 8123, ​this URL should give you access to that directory.

Test Grid Statistics

Usage statistics are available for the public test grid. NOTE: these are probably out of date and inaccurate. #13 and other tickets are where we're keeping track of better grid-wide instrumentation tools that we want to build.

These measurements have been broken by changes to the Tahoe source code.

count of directories in the grid

• other time scales

The following counts are samples of a single storage server, running four nodes. The test grid uses four servers, running a total of 13 nodes.

count of files stored in the grid

• other time scales: tahoebs1, tahoebs3, tahoebs4, tahoebs5

average shares per file

this hints at the number of nodes in the overall grid; If the number of hosts in the grid is less than 10, then shares_per_file should equal about 10/numhosts

• other time scales: tahoebs1, tahoebs3, tahoebs4, tahoebs5

total bytes consumed by all of the Tahoe test grid storage servers operated by Allmydata Inc.
