VM Disk Types

• All VMs have at least 2 disks - OS disk and temp disk. They can have 1+ data disk
• Disk are stored as .vhd and up to 1023GB
• OS disk: SATA drive and labelled as C by default
• Temp disk: labelled as D by default and for storing pagefile.sys
• Data disk: SCSI drive and labelled with my choice, stored in BLOB storage
• Depending on VM size, temp disk size and number of data disk are determined

VM Disks Management

• Attach, remove or modify data disk
• Modify settings
  • caching behaviour
  • size
• Storage spaces in VMs
  • Increase I/O throughput
  • Volume larger than 1TB
• Through portal
• Through PowerShell – Add-AzureDataDisk (ASM), Add-AzureVMDataDisk (ARM)
• Good to know
  • VM size determines number of data disks to Attach
  • Premium storage needs DS/FS/GS series VM
  • New/empty disk is created when attaching
  • When attaching, name, type, size, location and caching needs to be provided
  • Stored as .vhd files in blob storage
  • .vhd disk should already exist when attaching the existing disk

Disk Import & Export

• Useful to move large amount of data from on-prem hard disk to Azure blob storage (or vice-versa)
• Scenario:
  • Large amount of data migration to cloud
  • Content distribution
  • Backup
  • Data recovery
