Each Azure storage account comes with 500 TB of block blob storage capacity. However, this vast storage is not available to be used via an Azure VM. 

The best we can do right now is attach 16x 1TB disks (page blobs) to an A4 or bigger VM. This poses few problems:

1. 16TB is way too small for many use cases such as using Azure as backup/DR target
2. This coupling of storage to RAM/CPU is undesirable and drives enterprise clients to other cloud providers. 
   

When will Microsoft provide us the ability to make VHDX 64TB+ files in Azure block blob storage and attach them to Azure VMs?

Dozens of cloud providers make such functionality available. When will be able to have the same in Azure??

Hi Sam,

Thanks for your posting!

As your known, currently, Azure Disk max size is just u to 1TB. The new feature --Azure File Service max size is up to 5TB (http://blogs.msdn.com/b/windowsazurestorage/archive/2014/05/12/introducing-microsoft-azure-file-service.aspx ). For this issue, I suggest you could contact the Azure Technical support to resolve it. Or you can submit a feature request on the feedback page (http://www.mygreatwindowsazureidea.com/forums/34192-windows-azure-feature-voting.)

Regards,

Hello,

It is now possible to attach disks larger than 5TB virtual machines on Azure?

Hi Sam,

GS series offers up to 64 TB of (1x 64 TB) data disk space.  Please see more on GS series VM at http://azure.microsoft.com/blog/2015/01/08/largest-vm-in-the-cloud/.  It also can support up to 32 vCPUs using the latest Intel Xeon processor E5 v3 family, 448GB of memory, and 6.59 TB of local Solid State Drive (SSD) space.  Thanks.

HI Richardo,

The maximum size for OS disk is at 1 TB.  As for the data disks, you can stripe 5x1 TB disks to obtain a large disk size of 5 TB, and then attach to a VM.

It also depends on the size and series of the VMs.  Please see the following article https://msdn.microsoft.com/en-us/library/azure/dn197896.aspx?f=255&MSPPError=-2147217396 for more details.
