Description
The CEPHFS cluster is deployed in vmware virtual machines,The virtual machine memory configuration is 4G
Test with FIO
The order is as follows:
fio -name=task1 -filename=/mnt/testcephfs/fio-test-1 -rw=randwrite -ioengine=sync -size=1G -bs=4M -iodepth=1 -direct=0 -numjobs=1
Please look at the picture 1
Then I adjusted the virtual machine memory to 8G
The order is as follows:
fio -name=task1 -filename=/mnt/testcephfs/fio-test-1 -rw=randwrite -ioengine=sync -size=1G -bs=4M -iodepth=1 -direct=0 -numjobs=1
Please look at the picture 2
The question is: Why do you increase the VIRTUAL machine memory and perform the same fiO command and bW increase?
