I have recently deployed WS2016 DC on 4x DL380 G7s for PoC purposes. Each server has 4x 300GB 10K SAS drives, also, I have a couple of Intel SSDs that I can temporary borrow from my company. My main goal is to test different Storage Replica "modes" and deploy Scale-out File Server role on top of Storage Spaces Direct.

About a month ago, I have had a hard time deploying 2-node Storage Spaces Direct on a different hardware configuration (2 Supermicro servers). To be honest, the installation process was far from "straightforward". There was an issue with WinRM, the "unsupported bus type" error while I tried to "-Enable-ClusterS2D" and a few issues later when I tried to create a new tiered space.

Essentially, I am looking for the most up to date guidance on how to setup Storage Spaces Direct in 4 node environment using Powershell. Resiliency type is not important as I would like to test different resiliency settings.

Thank you for your help!

Speaking shortly, the deployment sequence looks as following:

  1. Deploy necessary WS roles and features
  2. Validate the Failover Cluster
  3. Create the Failover Cluster
  4. Enable Storage Spaces Direct

-EnableStorageS2D

  1. Create and configure storage pools

Example input:

New-StoragePool -StorageSubSystemName #CLUSTER_NAME# -FriendlyName #POOL_NAME# -WriteCacheSizeDefault 0 -ProvisioningTypeDefault Fixed -ResiliencySettingNameDefault Simple -PhysicalDisk (Get-StorageSubSystem -Name #CLUSTER_NAME# | Get-PhysicalDisk)

  1. Create and configure virtual disks

Example input:

New-Volume -StoragePoolFriendlyName #POOL_NAME# -FriendlyName #VD_NAME# -PhysicalDiskRedundancy 2 -FileSystem CSVFS_REFS –Size 100GB

  1. Deploy SOFS
  2. Create file shares That's it!

Here are two articles that I found helpful:

    I have configured Storage Spaces Direct following the guidance you have provided and will now deploy SOFS to test this setup further. Thanks for assistance! – Mwilliams Mar 6 '17 at 9:45

    Think twice before you do: 2-node S2D lacks local reconstruction codes support, and do two-way mirror only. TL;DR: disk failure during second node patch reboot will bring your cluster down. Also performance isn't that great at all: no DRAM write back cache, and CSV is read-only. – BaronSamedi1958 Mar 12 '17 at 9:41
  • May stil lbe good enough for an inidial POC. – TomTom May 11 '17 at 7:42
