hpxfer access role
Access to certain high-performance data transfer methods
This article is deprecated, since the hpxfer is no longer needed for
the new Rocky 9 services introduced Autumn 2024.
However, until the older machines (hpxfer[12] & gridftp1) are taken out of service,
the role is still required for access to those.
This article explains about access to high-performance data transfer services.
Some data transfer services are hosted in the JASMIN Data Transfer Zone (a special area of JASMIN’s network, located optimally for connections to the outside world via
JANET
) for increased performance. However, to
maintain security in this zone, access to some services is controlled via an additional access
role hpxfer. If you have a login account already, you can apply here for
this additional role:
If you will be connecting from your home institution directly via ssh or ssh- based gridftp to one of the servers in the JASMIN Data Transfer Zone, the specific IP address of your machine will need to be added to an allow-list. Please supply this as part of the application process above.
However, this should not be necessary if you are accessing the server from a remote server which is already allowed.
hpxfer is in order to use the Globus service on JASMIN, this is no longer required. You only need this role for accessing the hpxfer servers or for using certificate-based gridftp with the globus-url-copy command.
Inward pulls of data (to JASMIN) are possible by logging in to
hpxfer[1,2].jasmin.ac.uk via the login servers and pulling data from
external data sources. So if you’re not sure what IP address to use when
applying for access above, it is OK to quote the IP address of
login1.jasmin.ac.uk, i.e. 130.246.130.28 as a “dummy” value if you will
only be accessing them via this route, and not directly from outside.
