 For now, ultra disks have additional limitations, they are as follows:
 
-- Are supported in the following regions, with a varying number of availability zones per region:
-    - East US 2
-    - East US
-    - West US 2
-    - SouthEast Asia
-    - North Europe
-    - West Europe
-    - UK South 
-- Can only be used with availability zones (availability sets and single VM deployments outside of zones will not have the ability to attach an ultra disk)
+The only infrastructure redundancy options currently available to ultra disks are availability zones. VMs using any other redundancy options cannot attach an ultra disk.

+The following table outlines the regions ultra disks are available in, as well as their corresponding availability options:

 - Not every VM size is available in every supported region with ultra disks
 - Are only available as data disks and only support 4k physical sector size. Due to the 4K native sector size of Ultra Disk, there are some applications that won't be compatible with ultra disks. One example would be Oracle Database, which requires release 12.2 or later in order to support ultra disks.

+Azure ultra disks offer up to 16 TiB per region per subscription by default, but ultra disks support higher capacity by request. To request an increase in capacity, contact Azure Support.
