[Lustre-discuss] Off-topic: largest existing Lustre file system?

[D. Marc Stearman]

Klaus,

We currently have a 1.2PB lustre filesystem that we will be expanding  
to 2.4PB in the near future.  I not sure about the highest sustained  
IOPS, but we did have a user peak 19GB/s to one of our 500TB  
filesystems recently. The backend for that was 16 DDN 8500 couplets  
with write-cache turned OFF.
