[Lustre-discuss] Fwd: Lustre Thumper Fault Tolerance

[Mertol Ozyoney]

Hi,

You cant do this right now. Network striping will be intruduced later.

If you realy thing you need this kind of redundancy i reccomend you to  
wait for upcoming jbods.

Normally lustre can fail off the nodes when required and on hpc  
applications speed moght be more important then reliability.
