Confirming test parameters

["Hinson, Roger" <Roger_Hinson@intuit.com>]

	Hey all,

	I'm setting up a test to simulate what we're actually seeing on one of our storage arrays.  Can you take a look and provide me some feedback?

	The array usage is for two workload types:

	Type 1:
	Random Read % - 45
	Random Write % - 55
	Sequential Read % - 1
	Sequential Write % - 3
	R/W Ratio - 45:55
	Random Block Size - 4K
	Sequential Block Size - 64K

	Type 2:
	Random Read % - 1
	Random Write % - 13
	Sequential Read % - 2
	Sequential Write % - 84
	R/W Ratio - 3:97
	Random Block Size - 4K
	Sequential Block Size - 32K	

	I came up with this:

[global]
group_reporting=1
thread
iodepth=8
ioengine=libaio
direct=1
refill_buffers
randrepeat=1
randseed=100
random_distribution=zipf:1.01
runtime=1200
time_based
bs_is_seq_rand

[45read55write_dm0_numjobs_2]

write_iops_log=4555_dm0_2

rw=randrw
rwmixread=45
rwmixwrite=55
percentage_random=96
bs=64K,4K
buffer_compress_percentage=50

numjobs=2

[3read97write_dm1_numjobs_2]
write_bw_log=397_dm1_2
