High Speed File Transfer

This service is used for transferring large data between external collaborators and CHOP.

Sending/Sharing large amounts of data with outside collaborators

Aspera is a High Speed File Transfer System.  It requires an Aspers Server on the CHOP side and an Aspera client on the outside user end.  The client starts a file transfer connection to our Aspera Server.  Based on the credentials we deposit the data in a predetermined location for the receiver. 

Access is requested through Service Now

Best for very large file transfers into CHOP.

Sending/Sharing Files

Email like interface that allows secure file transfer of multi-gigabyte files to outside users.  Sender access requires a CHOP account but receiver accounts are generated dynamically.  To retrieve data from outside user there are options in the interface to “Send me a blind carbon copy” and “Allow recipient to send me back files”.  Checking these options gives the requestor access to the temporary storage location and the dynamic user and password required to open it.

Note:  the user, password and data are deleted in 7 days.  You must retrieve the data in that time or have it resent.
