Dear huang jun: This is a frequently requested feature. In fact, I see that there is an entry about this in the Frequently Asked Questions:
https://tahoe-lafs.org/trac/tahoe-lafs/wiki/FAQ#Q12_server_location_distribution I just updated that FAQ entry to include a link to the wiki page: https://tahoe-lafs.org/trac/tahoe-lafs/wiki/ServerSelection I hope that we're going to make progress on this issue again now that Brian's new accounting work is unstuck. It should be possible, with some programming (help welcome!) to make it do what you want. In the meantime, if you have 4 nodes in A and 6 nodes in B, you could try setting K=4, N=10. That should usually cause all 10 of the nodes to have a share, and usually a download from the A gateway will get all 4 shares from the A region and a download from the B gateway will get all 4 shares from the B region. If you try that, I would be interested to hear how it works.
