The VM Storage Pool is only for systems running firmware 11.x with the optional Intel® Modular Server Virtualization Manager (MFSVRT).
On the left side of the GUI, go to Settings > Firmware, and look at the Current Build Version.
If yours is 10.something, you can ignore references to virtual machines in the user guide.
If it is 11.something, check to see if, when the unit was purchased, they also bought the (optional) Virtualization Manager software as well.
