[Beowulf] Large amounts of data to store and process

[Rémy Dernat]

Hi,

I don't know exactly what you would like to do with these datas, but if 
I were you, I would take a close look at elasticsearch, spark or even 
hdf5, depending on what your analysis software looks like (is coded 
with...), to see if these technologies could save up some time. 
Moreover, I won't dismiss NFS easily, espacially if your infrastructure 
already use it.

Elasticsearch can be plugged easily with kibana.

Best regards,
