Shared disks on Azure Disk Storage are now generally available on all Premium SSD and Standard SSD sizes

Published date: July 19, 2021

With shared disks, Azure Disk Storage is the only shared block storage in the cloud that supports both Windows and Linux based clustered or distributed applications to run your most demanding enterprise applications – like clustered databases, parallel file systems, stateful containers, and machine learning applications – in the cloud, without compromising on well-known deployment patterns for fast failover and high availability.

Shared disk is now available on smaller Premium SSDs from 4 GiB to 128 GiB and all Standard SSDs from 4 GiB to 32 TiB. With these changes you can now:

  • Simply lift and shift your on-premises Windows or Linux based clusters to Azure.
  • Choose from a range of block storage options on Ultra Disk, Premium SSD, and Standard SSDs to optimize costs and performance based on your workload needs.
  • Configure zone redundant (ZRS) option for shared disks on Premium SSDs and Standard SSDs.
