I test GlusterFS on this equipment:
Backend LSI 7000, 80Tb, 24LUN's
4 OSS, Intel based server, connect to LSI via 8Gb FiberChanel, 12Gb RAM
Can you please clarify what OSS here means?
And, please mention what your GlusterFS configuration looks like.
Pavan
1 Intel based main server, connect to OSS via QDR InfiniBand, 12Gb RAM
and 16 Load Generators with 2 Xeon X5670, on board, 12Gb RAM. QDR InfiniBand
I use IOR for test , and get next results:
/install/mpi/bin/mpirun --hostfile /gluster/C/nodes_1p -np 16
/gluster/C/IOR -F -k -b10G -t1m

Why *read *< *write* ? It's normal for GlusterFS ?
