Absolutely AFM could be used in this manner.
A small GPFS instance on the local site would be used to cache the remote
filesystem in the off-site data centre.
There are sites already using AFM in this manner, it would also be
relatively straightforward to demonstrate AFM working by using a WAN
emulator to introduce latency/reduce bandwidth between Œcache' and
Œremote¹ GPFS Clusters if you wanted to carry out at a POC prior to the
Hope that helps.
