AzS-ACS01

The ACS01 VM is hosting the Azure Stack storage provider service. It is responsible for one of the most important resource providers. As the underlying storage technology is Storage Spaces Direct, this VM manages it.

If a tenant creates a new resource, it adds the storage account to a resource group. The storage account then manages the different storage services types on the physical host, such as BLOB, page, table, SOFS, ReFS cluster shared volumes, virtual disks, and Storage Spaces Direct. In addition, the storage account is the point to set up security, too. It's possible to add temporary (token based) and long-term (key based) storage.

When it comes to the roles for storage management, Azure Stack provides the following three levels:

• Storage Tenant Administrator (consumer of storage services).
• Storage Developer (developer of cloud-storage-based apps).
• Storage Service Provider (provides storage services for tenants on a shared infrastructure and can be divided into two separate roles):
  • Storage Fabric Administrator (responsible for fabric storage lifecycle)
  • Storage Service Administrator (responsible for cloud storage lifecycle)

The Azure consistent storage can be managed with:

• REST APIs
• PowerShell commandlets
• A modern UI
• Other tools (scripts and third-party tools)

Storage always needs to be a part of the tenant offer. It's one of the necessary pillars to providing resources within the Azure Stack.
