[gpfsug-discuss] AFM Alternative? Aspera?

[Venkateswara R Puvvada]

Transferring the small files with AFM  + NFS over high latency networks is 
 always a challenge. For example,  for each small file replication AFM 
performs a lookup, create, write and set mtime operation. If the latency 
is 10ms,  replication of each file takes minimum (10 * 4 = 40 ms)  amount 
of time. AFM is not a network acceleration tool and also it does not use 
compression.  If the file sizes are big, AFM parallel IO and parallel 
mounts feature can be used.  Aspera can be used to transfer the small 
files over high latency network with better utilization of the network 
bandwidth.

Maybe the following would assist? I do think tarring up files first is 
best, but you could always check out:
