0. Machine Informance
Node | 8 nodes (1 server , 7 client provide disks) |
CPU | Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz (each node) |
Memory | 2GB DDR2 667 (each node) |
Disk | 320G+160G (each node), All nodes: (320G+ 160G) * 7 = 3.36T |
NIC | Intel Corporation 82566DM Gigabit Network Connection |
Switch | D-link 24 port GE switch |
1. 8 Nodes, No Replicate, Adjust Parameters
$ iozone -g 16g -aRb test.wks
2. 8 Nodes, Replicate, Adjust Parameters
$ iozone -g 16g -aRb test2.wks
3. Comapre
The following six diagrams show the testing results using IOzone as the benchmark to evaluate how GPFS works with and without data-replication. The six IO operations we have done for performance evaluation are write, re-write, read, re-read, random read, and random write opertion, respectively. The left surface chart of each diagram represents the testing with data-replication enable, and the right one is opposite.
