Hi, I'm new to Globus. I need to set up a high-performance, reliable file-transfer service between two sites linked by WAN. After some inquiry we decided that GridFTP with RFT would work well in our setup.
Here is our setup and requirements : -- Two sites, A and B linked by WAN -- Site A has 3 servers, Site B has 2 servers -- Large files (upto 50 GB) need to be transferred from site A to site B. -- Note: more servers can be included on each site at a later stage, right now we have only 5 in total. Here are some questions : 1) Do I need to install all of GT 4.2.1 on each host or can I just install GridFTP on 4 hosts ( 2 in A and 2 in B) and RFT on the 5th ? I intend RFT to be on a separate machine from the GridFTP hosts, is this ok ? 2) Recent GT documentation mentions that a separate database (PostGreSQL, MySql) is not required since GT uses an internal DB called "Derby". Does RFT need this internal database ? 3) If we wanted to transfer a large file from Site A to Site B, how can we setup the system so that the all the GridFTP servers in both sites can be used for transferring the file ? I assume that using more servers will result in a faster file transfer, is this correct ? if so how to set it up ? 4) For authentication between the servers and certificate management, is MyProxy required on each server or is only one instance of it required ? 5) Is there any example of GridFTP setups anywhere, i.e. documentations on such setups etc that I can refer to ? Thanks in advance Arn
