4TB disk sizes for Azure IaaS VMs available

2017/07/07

Microsoft has introduced two new disk sizes for Azure IaaS VMs in P40 (2TB) and P50 (4TB) for both managed and unmanaged Premium Disks and S40 (2TB) and S50 (4TB) for both managed and unmanaged Standard Disks.  This enables customers to add 4x more disk storage capacity per VM.  Customers can now provision up to a total of 256TB disk storage on a GS5 VM using 64 disks with 4TB capacity.  This means the max SQL Server database size on a Azure VM goes from 64TB to 256TB!

Premium Disks Standard Disks
Managed Disks P40, P50 S40, S50
Unmanaged Disks P40, P50 Max up to 4,095GB

Larger Premium Disks P40 and P50 will support your IO intensive workload and therefore offer higher provisioned disk performance. The maximum Premium Disk IOPS and bandwidth is increased to 7,500 IOPS and 250 MBps respectively.  Standard Disks, of all sizes, will offer up to 500 IOPS and 60 MBps.

P40 P50 S40 S50
Disk Size 2048GB 4095GB 2048GB 4095GB
Disk IOPS 7,500 IOPS 7,500 IOPS Up to 500 IOPS Up to 500 IOPS
Disk Bandwidth 250 MBps 250 MBps Up to 60 MBps Up to 60 MBps

You can create a larger disk or resize existing disks to larger disk sizes with your existing Azure tools through Azure Resource Manager (ARM) or the Azure Portal.  Azure Backup and Azure Site Recovery support for larger disks is coming soon (current timeline is before end of July).

You can visit the Managed Disk Pricing and unmanaged Disk Pricing pages for more details about pricing.
