Q: What is the maximum number of disks I can add to a Windows Azure IaaS virtual machine (VM)?

A: It's possible to add additional virtual disks to a Windows Azure IaaS VM, which can be up to 1TB in size. The exact number that are supported depends on the size of the VM, with the maximum number being 16 for A5 (ExtraLarge) and A7 size VMs. The best reference is at Microsoft's MSDN site, which gives the details of the exact capabilities of each size of VM.
