Azure Local Storage

Question

I have 3 node Azure Local, and in the cluster storage i have 3 storage like below pic.

Can i know those 3 server indicated storage for each node? And also is the content of the storage will be same for all nodes? Example data i userstorage_1 will be identically same with userstorage_2 and userstorage_3?

Hi Handian Sudianto,

thx for asking here at Q&A portal. So based on your screenshot and description, you're working with an Azure Stack HCI (Hyper-Converged Infrastructure) 3-node cluster.

Storage Structure in Your Cluster

Folder Structure

• Infrastructure_1: Typically contains cluster system files and management data
• UserStorage_1, UserStorage_2, UserStorage_3: These appear to be storage pools for each node

Are these storages for each node?

• Yes, in a 3-node Azure Stack HCI cluster, each UserStorage_X typically corresponds to storage from each physical node
• The numbering usually (but not always) matches the node numbering

Data Replication and Consistency. Default Behavior

• Data is NOT automatically identical across all storage locations
• Each node maintains its own storage unless you've configured replication

Replication Options

• Mirrored volumes Data is duplicated across nodes (usually 2 or 3 copies)
• Parity volumes More space-efficient but with performance tradeoffs
• Non-replicated Data exists only on one node (vulnerable to node failure)

For check urs config

Get-VirtualDisk | Select FriendlyName, ResiliencySettingName, NumberOfDataCopies
Get-StoragePool | Select FriendlyName, HealthStatus, OperationalStatus

Ms best practices. For important data use 2-way or 3-way mirroring depending on your redundancy needs. For capacity optimization consider parity volumes for less critical data. And of coz monitoring set up alerts for storage health using

Get-StorageHealthReport -Name "StorageNode*"
