Azure

The Azure virtual cluster has the same interface as a PowerScale OneFS on-premises cluster.

Azure managed disk types

Table 3. Azure managed disk Supported Azure managed disks.
Drive family	Description	Workflow
Premium SSD locally redundant storage (LRS)	Locally Redundant Premium SSD	High performance, low latency, input/output (IO)-intensive workloads. Premium SSDs are suitable for mission-critical production applications.
Standard SSD locally redundant storage (LRS)	Locally Redundant Standard SSD	Consistent performance with lower IOPS levels. Standard SSds are suitable for lightly used enterprise applications or workloads.
Standard HDD locally redundant storage (LRS)	Locally Redundant Standard HDD	Latency tolerant workloads. Development testing and less critical workloads.
