Performance of Azure Shared Disk with Zone Redundant Storage (ZRS)

On September 9th, 2021, Microsoft announced the general availability of Zone-Redundant Storage (ZRS) for Azure Disk Storage, including Azure Shared Disk.

What makes this interesting is that you can now build shared storage based failover cluster instances that span Availability Zones (AZ).  With cluster nodes residing in different AZs, users can now qualify for the 99.99% availability SLA. Prior to support for ZRS, Azure Shared Disks only supported Locally Redundant Storage (LRS), limiting cluster deployments to a single AZ, leaving users susceptible to outages should an AZ go offline.
