WebHostManager question

In WebHostManager, when looking at Service Status, at the bottom of the chart I see these:

Disk hdb7 (/) No DMA! (Click to Enable) 42 %
Disk hdb1 (/boot) No DMA! (Click to Enable) 19 %
Disk hdb6 (/tmp) No DMA! (Click to Enable) 4 %
Disk hdb2 (/usr) No DMA! (Click to Enable) 25 %
Disk hdb3 (/var) No DMA! (Click to Enable) 13 %

Can anyone tell me what these are?
