What is Storage Spaces Direct In Windows 2016?

Windows 2016 will continue to focus on Software Defined Storage. In Windows 2012 Storage spaces was introduced as a tool that would allow pooling together disk resources to create a large and redundant pool of disk space (Similar to Raid but without certain limitations-Such as all disks must be of the same size).  Storage spaces could also be used in a cluster environment as long as the Storage space as based on a JBOD with direct SAS connectivity to both nodes in the Cluster.

In Windows 2016 we’re receiving storage spaces direct. This technology will allow us to pool multiple local DAS disks from Multiple servers in to one pool. That’s correct local disks from multiple servers into one large shared pool. The pool can be used in a failover cluster for storing your Hyper-V VM’s.

just think, you can have 3 servers all with 3TB of local disk space all pooled together to create a large pool of clustered disk space. Now that’s COOL!
The pool will be fault tolerant and the loss of a single server will not bring down the pool itself.

The possibilities are endless. Smaller environments will defiantly be able create clusters without purchasing expensive Storage appliances, data can be stretched to a remote site for DR scenarios. Yes this is also totally supported.

I’ve been playing around with the preview version, and so far things look extremely cool.

  1. Hi Gill,

    Can you confirm the minimum number of nodes required for this to work? I’ve seen four nodes referenced but wasn’t sure ifvthus was mandatory?

    We make use of storage spaces extensively and have been watching this feature for a while, would be better if we could start with two nodes then scale out as needed.
