Storage types:
- DAS Direct Attached Storage
- NAS Network Attached Storage
- SAN Storage Area Network

Network Attached Storage
- Makes storage available over the IP network
- Provides centralized management
- Typically supports multiple protocols such as NFS, SMB, or CIFS
- Fairly inexpensive and easy to setup
- Slow performance, not really an enterprise solutions for storage

Block-level vs. File-level Storage
- Block level
   Provides good performance
   Typically SAN-based
   Presents LUNs to servers
   Higher cost compared to NAS-based solutions

- File level
   Accessed via NAS or file server
   Uses NFS, SMB or CIFS
   Connects to backend block-level storage
   Typically more cost effective

Fibre Channel and iSCSI
FC - Fiber Channel used with HBA and FC switch
FCoE - Fiber Channel over Ethernet
iSCSI - Internet SCSI

Understanding iSNS, DCB, and MPIO
iSNS - Reduces administrative overhead (Internet Storage Name Service) 
DCB - Traffic enhancement for storage networks (Data center bridging)
MPIO - provides multiple paths to block storage

Understanding SMB

Operating system	SMB version
Windows 10 and Windows Server 2016	SMB 3.1.1
Windows 8.1 and Windows Server 2012 R2	SMB 3.0.2
Windows 8 and Windows Server 2012	SMB 3.0
Windows 7 and Windows Server 2008 R2	SMB 2.1
Windows Vista and Windows Server 2008	SMB 2.0.2
Previous versions	SMB 1.x

For SMB & NFS appropriate roles on the server need to be installed
