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.



New De-Dupe features coming to Windows 2016

In its current beta Windows 2016 offers new Dew-Dupe features and rumors say that more are to come.

What we currently know is the following:

1. Volume size of up to 64 TB will be supported.

In Windows 2016 the recommended limit was 10 TB mainly due to processing rates. The new De-Dupe has a new engine with multiple threads supported to improve performance.

2. File sizes up to 1 TB are good.

Although supported in Windows 2012, again not recommended because of performance issues. In Windows 2016 1TB file sizes are good to go (DE-Dupe).

3. New type of DE-Dupe scenario – Backup.

Windows 2012R2 supported general File Server & virtualization (VDI) De-Dupe.

Not sure exactly what the improvement here is, but we’re promised better performance for De-Duping backup files. Can’t wait to try it out with Veeam.
