Updated: March 18, 2020
Azure Shared Disks is a shared block storage offering, enabling customers to run latency-sensitive workloads without compromising on well-known deployment patterns for fast failover and high availability. Azure Shared Disks are best suited for clustered databases, parallel file systems, persistent containers, and machine learning applications.
Azure Shared Disks provide a consistent experience for applications running on Windows or Linux based clusters today. These include, Global File System 2 (GFS2), SQL Server Failover Cluster Instances (FCI), Scale-out File Servers (SoFS) which leverage SCSI Persistent Reservations (PR) to handle cluster node communication as well as write locking.
