#Windows server 2012 Storage Spaces – using PowerShell – via LazyWinAdmin

Very good work on this blog post about Windows Storage Spaces!

WS2012 Storage – Creating a Storage Pool and a Storage Space (aka Virtual Disk) using PowerShell

 

In my previous posts I talked about how to use NFS and iSCSI technologies hosted on Windows Server 2012 and how to deploy those to my Home Lab ESXi servers.

One point I did not covered was: How to do the Initial setup with the physical disk, Storage pooling and the creating the Virtual Disk(s) ?

The cost to acquire and manage highly available and reliable storage can represent a significant part of the IT budget. Windows Server 2012 addresses this issue by delivering a sophisticated virtualized storage feature called Storage Spaces as part of the WS2012 Storage platform. This provides an alternative option for companies that require advanced storage capabilities at lower price point.

Terminology

Storage Pool: Abstraction of multiple physical disks into a logical construct with specified capacity
Group of physical disks into a container, the so-called storage pool, such that the total capacity collectively presented by those associated physical disks can appear and become manageable as a single and seemingly continuous space.

There are two primary types of pools which are used in conjunction with Storage Spaces, as well as the management API in Windows Server 2012: Primordial Pool and Concrete Pool.

Primordial Pool: The Primordial pool represents all of the disks that Storage Spaces is able to enumerate, regardless of whether they are currently being used for a concrete pool. Physical Disks in the Primordial pool have a property named CanPool equal to “True” when they meet the requirements to create a concrete pool.

 

Concrete Pool: A Concrete pool is a specific collection of Physical Disks that was formed by the user to allow creating Storage Spaces (aka Virtual Disks).


Storage Space: Virtual disks with associated attibutes that include a desired level of resiliency, thin of fixed provisioning, automatic or controlled allocation on diverse storage media, and precise administrative control.

Storage Virtualization Concept

This diagram from Yung Chou shows nicely how the different parts of Windows Server 2012 Storage work together.

Deployment Model of a Storage Space (Virtual Disk)

In order to understand the deployment model of a Storage Space, I created the following diagram…
