Storage Spaces Direct

Question

Some background: I'm trying to set up Azure Pack in a test environment, and are currently woriking on setting up the servers who's going to host it all.

To do this i have two virtual Windows Server 2016 TP4 servers hostet on a ESXI host, and so i need to set up Storage Spaces Direct. (iSCSI target and Storage Spaces (WS 2012), have been ruled out since the first is a nightmare to set up and the internet told me the second one comes with a low R/W speed).

I've been following this guide: https://technet.microsoft.com/en-us/library/mt126109.aspx

Problem: When i run this cmdlet: Enable-ClusterStorageSpacesDirect , I get this warning: No elegible DAS disk found.

Both servers have 3 disk each. They are initialized and 100% unallocated, and I have tried with them beeing both offline and online.

If I try running this cmdlet: (Get-Cluster).DasModeEnabled=1 I get the following error: The property 'DasModeEnabled' cannot be found on this object. Verify that the property exists and can be set.

Any and all help is greatly appriciated!

Storage Spaces Direct doesn't support FC & RAID-controlled LUNs. The key is to force S2D to accept RAID BusType:

(Get-Cluster).S2DBusTypes=256

Here's a good article about it https://www.starwindsoftware.com/blog/resolving-enable-clusters2d-bus-type-support-issue-on-some-storage-controllers . Another option is to reflash the controller's firmware to IT mode.

There's also other solutions, like that Starwind, which I suggest you to test.
