...r lustre setup with a constant 400MByte/s throughput, for the same tests, with the same amount of disks going through the same RAID controller. Both tests were ran at different times. As comparison, for the sequential reading tests, both gluster and lustre give me, respectively, results of 600 to 700MByte/s. The gluster configuration files have no extra modifications, the disks are formatted with ext3 and created via: gluster volume create test stripe 16 transport rdma 10.1.0.4:/disk1 10.1.0.4:/disk2 ... 10.1.0.4:/disk16 Using DD to write/read from each of the disks gives me about 100MByte/s....

...de, that is the bandwidth , and throughput seen from the NFS sever on the other side of the nodes shows a liner increment from around 100+Mbyte/sec up to 1Gbyte/sec, however when we add another extra node to the equation the bandwidth/throughput becomes erratic/inconsistent, and drops to around 500-700Mbyte/sec. however if i try the same setup with RHEL4U6 i do not get the same behaviour it sustains the bandwidth at 1Gbyte/sec. the setup is like this 48 nodes sharing 48 port access switch that is up linked using 10g link to a CISCO 6509 switch which is linked to a Clustered NFS File system that consi...
