		+	== Creating Multi-Disk vdisk tiers ==
		+
		+	The create command can use two internal Enmotus disks as arguments instead of raw block devices. In this case a vdisk needs to be preconfigured prior to being placed as a tier.
		+
		+	=== Creating vdisks ===
		+
		+	The tiering engine support pooling of physical disk drives in either a linear concatenation or stripe mode. Striping is implemented around tiering page boundaries with a stripe size the same as the page size setting for the tdisk (default 4M). Up to a maxium of 16 devices can be combined into a pool, with valid modes of linear or stiping.

 == Create a Fuze Drive ==
+There are several pssoble ways to create a tiered volume, depending on the number and configuration of the disk required. Before creating a disk you will need to list the available disks that can be used:
