What is the maximum count of shared storage disks that can be attached to an Azure VM?

Hello @Ravi Sajjanar

In addition to what Jackson Martins suggested the maximum number of Azure shared disks that can be attached to a single VM depends on the VM size and the disk size.
For example, a Standard_DS14_v2 VM can attach up to 64 disks, while a Standard_DS1_v2 VM can attach up to 4 disks. The maximum size of a single disk is 32 TB, and the maximum total size of all disks attached to a VM is 256 TB.

Regarding the multipath concept, Azure Shared Disks support multipathing. Multipathing is a technique that allows a server to use multiple physical paths to access a storage device. This provides redundancy and load balancing, which can improve performance and availability. Azure Shared Disks use the iSCSI protocol, which supports multipathing. When you attach a shared disk to a VM, you can configure multipathing on the VM to take advantage of this feature.

Hi @Ravi Sajjanar The maximum number of disks, varies by the type and size of the disk:

Sample:
Premium SSDs have limits that range from 3 to 10, depending on the disk size. For instance, smaller sizes like P1 to P20 allow up to 3 shares, while larger sizes like P60 to P80 allow up to 10 shares.

Ultra Disks and Premium SSD v2 offer more flexibility, allowing a maxShares value up to 15, regardless of the disk size.
