In this episode, Distinguished Engineer and Lead Architect for Windows Server, Jeffrey Snover discuss new storage management features in Windows Server 8, how it integrates with PowerShell and System Center Virtual Machine Manager 2012 as well as what this all means for Cloud Computing and Virtualization going forward.
Windows Server 8 introduces a new WMI-based API called the Storage Management API (SMAPI) and corresponding set of PowerShell Cmdlets. These provide storage management primitives to manage direct attach storage on the OS as well as external storage arrays. The PowerShell Cmdlets replace tools like diskpart and diskraid. The API is comprised of a WMI object model along with the corresponding set of methods and properties. Storage partners plug into the new API either by:
- Implementing the SNIA (Storage Networking Industry Association) industry standard for storage management called SMI-S (Storage Management Initiative -Specification)
- Implementing a new provider model called the Storage Management Provider (SMP)
SCVMM 2012 uses its storage management capabilities to deliver three scenarios:
- End-to-end Mapping
- Identify how VM, hosts, and clusters relate to the underlying storage infrastructure
- Adding storage to a host or cluster including unmasking, initialization, partitioning, formatting, validating, and CSV cluster resource creation (in shared storage case)
