<p style="margin:0cm;margin-bottom:.0001pt"><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial",sans-serif"> </span><span style="font-size:10.0pt;font-family:"Arial",sans-serif"><o:p></o:p></span></p>
<p style="margin:0cm;margin-bottom:.0001pt"><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial",sans-serif">We are currently building a 3 site spectrum scale solution where data is going to be generated at two different sites (Site A and Site B,
Site C is for archiving/backup) and then archived on site three. </span><span style="font-size:10.0pt;font-family:"Arial",sans-serif"><o:p></o:p></span></p>
<p style="margin:0cm;margin-bottom:.0001pt"><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial",sans-serif">I have however not worked with AFM much so I was wondering if there is someone who knows how to configure AFM to have all data generated in
a file-set automatically being copied to an offsite. </span><span style="font-size:10.0pt;font-family:"Arial",sans-serif"><o:p></o:p></span></p>
<p style="margin:0cm;margin-bottom:.0001pt"><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial",sans-serif">GPFS AFM is not an option because of latency between sites so NFS AFM is going to be tunneled between the site via WAN.

<p style="margin:0cm;margin-bottom:.0001pt"><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial",sans-serif">As of now we have tried to set up AFM but it only transfers data from home to cache when a prefetch is manually started or a file is being
opened, we need all files from home to go to cache as soon as it is generated or at least after a little while.
