Lab

Disk Benchmarking Lab with PerfMon

The instructor will provide the following instructions:

  1. Attach 4 Data Disks (Standard_SSD) on a Windows VM (A2_v2 size), 32 GiB each.
  2. Create a Virtual Disk using Storage Spaces, by combining the 4 disks with Simple (striping) layout.
  3. Run disk benchmarking (i.e.: DiskSpd) tests with below commands:
diskspd.exe -c1024M -d10 -W5 -o1 -t1 -b8k -r -Sh -L f:\test.dat
diskspd.exe -c1024M -d10 -W5 -o1 -t4 -b8k -r -Sh -L f:\test.dat

评估差异

  • Evaluate the differences in terms of IOPS and avg latency
  • Repeat the exercise by increasing the -o value from -o1 to -o16 and -o32: can you see the difference?
