SYA810 RAID Benchmarking Lab

Task

The machine 'scotland' is equipped with six 1.5TB disk drives. Partition 9 on each drive is unused. We're going to use these partitions to benchmark various RAID levels.

1. Create a RAID array of the six partitions (/dev/sd[a-f]9) using the appropriate mdadm command(s).

1. Create an ext3 filesystem on that array.

1. Benchmark the array using the Winter_2009_SYA810_Block_Device_Benchmark_Scripts. Repeat the benchmarks at least 3 times -- more if the results seem to vary substantially.

1. Stop the RAID array.

Important Notes

• Do not use any devices other than /dev/sd[a-f]9 as members of the array.

• Do not have any spare elements in your array.

• Make sure the system is quiet (not doing any background processing) when you run your tests.
