Lustre Performance Report (Uses iozone command)


0. Machine Informance

Node 4 nodes (1 server , 3 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) * 3 = 1.4T
NIC Intel Corporation 82566DM Gigabit Network Connection
Switch ZyXEL GE switch

1. 4 Nodes, No Replicate, Adjust Parameters

$ iozone -g 16g -aRb test.wks


3. Performance

The following six diagrams show the testing results using IOzone as the benchmark to evaluate how Lustre 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.
