Four layers
>Compute layer
Several Hyper-V hosts joined in a failover cluster.
Use commodity server hardware to provide cost-efficient scale-out capabilities.
Scale-out approach is more cost-effective than Scale-up approach.
>Network layer
A low-cost Ethernet network is used to connect the Hyper-V cluster.
Provide compute resources with Scale-out File Servers.
It's more cost-effective than using SAN. Expensive host bus adapters not needed.
It's posible because of smb 3.0 is introduced in windows server 2012.
>Virtualized storage layer
Virtual machines files(virtual hard disks,configuration files etc) and other data such as sql data can be stored in the SoFS
>Physical storage layer
Can be stored on different types of storage devices(SATA,SAS,HDDs,SSDs)
Just a Bunch of Disks
