Details
(No major change in WS2019)The R2 release of Server 2012 added several storage related features:
- Support for shared virtual hard disks, enabling clustering of virtual machines by using shared virtual hard disk (VHDX) files (can be hosted on CSVs or SMB-based Scale-Out File Server file shares).
- Hyper-V Live Migration over SMB - enables you to perform a live migration of virtual machines by using SMB 3.0 as a transport (SMB Direct and SMB Multichannel for high speed migration with low CPU utilization)
- Improved SMB bandwidth management (configure SMB bandwidth limits to control different SMB traffic types: default, live migration, and virtual machines
Server 2012 introduced a large number of storage related enhancements.
Server 2012 / R2 virtualization hosts support (almost) all commonly available storage types as attachments for virtual machines. The biggest improvement has been the addition of network attached storage allowing you to configure (cheaper/simpler) network-based storage for virtual machines using the SMB3 protocol. New file server features include transparent failover, networking improvements for better bandwidth and resiliency, support for network adapters with RDMA capability, specific performance optimizations, Volume Shadow Copy Service support and support for Windows PowerShell commands.
Another enhancement with WS 2012 was the addition of virtual fibre channel for the virtual machines. Virtual Fibre Channel lets virtual machines connect directly to Fibre Channel-based storage and presents virtual HBA ports in the guest operating system. This provides: Unmediated access to a SAN, Hardware-based I/O path to the Windows software virtual hard disk stack, Live migration, N_Port ID Virtualization (NPIV), Single Hyper-V host connected to different SANs with multiple Fibre Channel ports, Up to four virtual Fibre Channel adapters on a virtual machine, Multipath I/O (MPIO)

Hyper-V in Windows Server 2012 also introduced an update to the VHD format, called VHDX, that has much larger capacity and built-in resiliency.
Windows Server 2016 brings Storage Spaces Direct that enable to implement Hyperconverged or disaggregated solution. Storage Spaces Direct enables the use of direct attach storage devices inside servers to create a highly available storage solution.

Sotrage Spaces Direct requires Windows Server 2016 Datacenter edition. This feature is not availablr in Windows Server 2016 Standard
