Description of problem:
To get the baseline Random write IOPS of SSD gluster volume, that is added as a
storage domain in RHHI so as to provide block storage to VM provisioned, is
mounted on of the hosts and a fio random write run is executed over it. Later,
the same volume was added as a storage domain and added as a block device to
the Virtual Machine(VM) running on top of RHHI and the same fio random write
test is executed within the VM. Following are the results:

1. Baseline Random Write IOPS: 6456
2. Virtual Machine Random Write IOPS: 602
