The following list contains Ultra Disk's limitations:
13
-
- Ultra Disk can't be used as an OS disk.
14
-
- Currently, Ultra Disk only supports Single VM and Availability zone infrastructure options.
15
-
- Ultra Disk doesn't support availability sets.
16
-
- The size of an Ultra disk can't be expanded without either deallocating the VM or detaching the Ultra disk.
17
-
- 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).
18
-
- 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.
19
-
- Azure Site Recovery isn't supported for VMs with Ultra disks.
20
-
- Ultra Disk doesn't support disk caching.
21
-
- Snapshots are supported with [additional limitations](../articles/virtual-machines/disks-incremental-snapshots.md#incremental-snapshots-of-premium-ssd-v2-and-ultra-disks).
22
-
- 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.
