-The following list contains Ultra Disks's limitations:
-- Can't be used as OS disks.
-- Doesn't support disk export.
-- Doesn't support VM images.
-- Doesn't support availability sets.
-- Doesn't support Azure Disk Encryption.
-    - Can't be attached to existing VMs previously encrypted with Azure Disk Encryption.
-- Doesn't support Azure Site Recovery.
-- Doesn't support disk caching.
-- Must deallocate your VM or detach your ultra disk in order to expand your Ultra Disk
-- Existing disks currently can't change their type to an Ultra Disk. They must be [migrated](../articles/virtual-machines/disks-convert-types.md#migrate-to-premium-ssd-v2-or-ultra-disk).

+The following list contains Ultra Disk's limitations:
+- Ultra Disk can't be used as an OS disk.
+- Currently, Ultra Disk only supports Single VM and Availability zone infrastructure options.
+- Ultra Disk doesn't support availability sets.
+- The size of an Ultra disk can't be expanded without either deallocating the VM or detaching the Ultra disk.
+- Existing disks currently can't change their type to an Ultra disk. They must be [migrated](../articles/virtual-machines/disks-convert-types.md#migrate-to-premium-ssd-v2-or-ultra-disk).
+- Azure Disk Encryption isn't supported for VMs with Ultra disks. We recommend you to use encryption at rest with platform-managed or customer-managed keys, which is supported for Ultra Disk.
+- Azure Site Recovery isn't supported for VMs with Ultra disks.
+- Ultra Disk doesn't support disk caching.
 - Snapshots are supported with [additional limitations](../articles/virtual-machines/disks-incremental-snapshots.md#incremental-snapshots-of-premium-ssd-v2-and-ultra-disks).
-- Azure Backup support for VMs with Ultra Disks is [generally available](../articles/backup/backup-support-matrix-iaas.md#vm-storage-support). Azure Backup has limitations when using Ultra Disks, see [VM storage support](../articles/backup/backup-support-matrix-iaas.md#vm-storage-support) for details.

 Ultra disks support a 4k physical sector size by default but also supports a 512E sector size. Most applications are compatible with 4k sector sizes, but some require 512-byte sector sizes. Oracle Database, for example, requires release 12.2 or later in order to support 4k native disks. For older versions of Oracle DB, 512-byte sector size is required.
