I have Samsung SSD PM1633 , I use them in RAID 10 with 12 SSDs with Hardware RAID,
i run FIO on it, with below option:
direct=1, iodepth=32, numjobs=8 , bs=8k, runtime=180, rw=randrw, rwmixread=70, ioengine=libaio,
I use fio as directly on the server , output :
IOPS Read : 90.3k
IOPS write: 38.7k
Latency Read: 2059 u
Latency Read: 1807 u
my question is:
1. do really I get IOPS Disks?
2. do this IOPS with this latency is real?
as mentioned , this results are as local,
3. but test remote with FC to host show low iops, what is reason?
