View source for 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.

# Create a RAID array of the six partitions (/dev/sd[a-f]9) using the appropriate mdadm command(s).
# Create an ext3 filesystem on that array.
# 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.
# 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.

== Who's Doing Which RAID Level ==

Write you name on here according to RAID levels chosen in class.
