For [Windows VMs](/azure/virtual-machines/windows/disk-encryption-faq), Azure Disk encryption selects the encryption method in BitLocker based on the version of Windows, for example, XTS-AES 256 bit for Windows Server 2012 or greater. These crypto modules are FIPS 140 validated as part of the Microsoft [Windows FIPS validation program](/windows/security/threat-protection/fips-140-validation#modules-used-by-windows-server). For [Linux VMs](/azure/virtual-machines/linux/disk-encryption-faq), Azure Disk encryption uses the decrypt default of aes-xts-plain64 with a 256-bit volume master key that is FIPS 140 validated as part of DM-Crypt validation obtained by suppliers of Linux IaaS VM images in Microsoft Azure Marketplace.

-[Customer-managed keys](/azure/virtual-machines/disk-encryption#customer-managed-keys) enables you to have control over your own keys that can be imported into or generated inside Azure Key Vault or Managed HSM. This approach relies on two sets of keys as described previously: DEK and KEK. DEK encrypts the data using an AES-256 based encryption and is in turn encrypted by an RSA KEK that is stored in Azure Key Vault or Managed HSM.

With the volume hard quota change, Azure NetApp Files volumes are no longer thinly provisioned at (the maximum) 100 TiB. The volumes are provisioned at the actual configured size (quota). Also, the underlying capacity pools no longer automatically grow upon reaching full-capacity consumption. This change reflects the behavior like Azure managed disks, which are also provisioned as-is, without automatic capacity increase.

Based on your inputs, the capacity planner gives you the required memory size and CPU core count. Use this information to choose the appropriate Azure VM size. The capacity planner also provides total disk size required for the VM along with the required disk IOPS. We recommend using a standard SSD disk for the VM. By pooling more than one SSD, you can achieve the required IOPS.
