[Lustre-discuss] gridftp and Lustre

[Yujun Wu]

Hi Jeffrey,

Thanks for your e-mail. Then extra traffic is moving from gridftp servers
to OSSs, which I really don't like---as you may imagine.

I know a product called dCache. The gridftp servers don't handle the data
traffic directly, but re-directing the data to the data server(dCache
pools). 


Regards,
Yujun
