az disk

Manage Azure Managed Disks.

Azure Virtual Machines use disks as a place to store an operating system, applications, and data. All Azure virtual machines have at least two disks: An operating system disk, and a temporary disk. The operating system disk is created from an image, and both the operating system disk and the image are actually virtual hard disks (VHDs) stored in an Azure storage account. Virtual machines also can have one or more data disks, that are also stored as VHDs.

                        Azure Managed and Unmanaged Data Disks have a maximum size of 4095 GB (with the exception of larger disks in preview). Azure Unmanaged Disks also have a maximum capacity of 4095 GB.
