Hi Tom, 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 move. Hope that helps.
