-### RAM
-
-2 GB for 64-bit images
-
-Note: 2GB for standard 30GB disk image with higher amounts of memory for larger disks.  see [How to Find Windows 10 Computer Specifications & Systems Requirements](https://www.microsoft.com/en-US/windows/windows-10-specifications).
-
-### Volume Size:
-
-Minimum volume size 64 MB
-Best practice is to allocate 8-10MB free space of bitlocker metadata in a 20GB volume and leave a proportional additional amount of free space available as the volume size increases.
-
-### Partition:
-
-Windows Server 2016 and above:
-Bitlocker can only be enabled in a subset of partition schemas, to meet this requirement bdecfg is a tool that will configure the partition schema to work with bitlocker, below are some of the partition requirements for system partition and WinRE partition.
-
-BitLocker must use a system partition that is separate from the Windows partition, with the following requirements:
-
-- Must be configured as the active partition.
-- Must not be encrypted or used to store user files.
-- Must have at least 350 megabytes (MB) of space.
-- Must have at least 50 MB of free space.
-- May be shared with a recovery partition.
-
-For more information, see [BitLocker Drive Encryption](/windows-hardware/manufacture/desktop/bitlocker-drive-encryption).
-
-For VMs with Win RE partition, Bitlocker has minimum partition requirement inherited from WinRE:
-
-- This partition must be at least 300 MB.
-
-The Windows Recovery Environment (Windows RE) tools require additional free space:
-
-- If the partition is less than 500 MB, it must have at least 50 MB of free space.
-- If the partition is 500 MB or larger, it must have at least 320 MB of free space.
-- If the partition is larger than 1 GB, we recommend that it should have at least 1 GB free.
-
-When calculating free space, note:
-
-- The recovery image, winre.wim, is typically between 250-300MB, depending on what drivers, languages, and customizations you add.
-- The file system itself can take up additional space. For example, NTFS may reserve 5-15MB or more on a 750MB partition.
-- The recovery tools should be in a separate partition than the Windows partition to support automatic failover and to support booting partitions encrypted with Windows BitLocker Drive Encryption.
-
-We recommend that you place this partition immediately after the Windows partition. This allows Windows to modify and recreate the partition later if future updates require a larger recovery image.
-
-For more information, see [UEFI/GPT-based hard drive partitions](/windows-hardware/manufacture/desktop/configure-uefigpt-based-hard-drive-partitions).
-
-Windows Server  2008:
-
-Please follow the requirements documentated in the [Description of the BitLocker Drive Preparation Tool](https://support.microsoft.com/en-us/help/933246/description-of-the-bitlocker-drive-preparation-tool).
+> [!NOTE]
+> New ADE implementation is supported for RHEL OS and data disk for RHEL7 Pay-As-You-Go images. ADE is currently not supported for RHEL Bring-Your-Own-Subscription (BYOS) images.
