SAN vs NAS:
SAN = Storage Area Network
NAS = Network Attached Storage
SAN:
✅ Block-level storage
✅ Connected via Fibre Channel (or) iSCSI
✅ Used for high-performance applications like databases, virtualization, and enterprise workloads
✅ Faster, more complex, and highly scalable
Examples: Dell EMC PowerMax, HPE 3PAR
NAS:
✅ File-level storage
✅ Connected over Ethernet
✅ Ideal for shared folders, backups, media, and SMB/SME environments
✅ Easy to set up, manage, and scale
Examples: Synology, QNAP
Quick Summary:
- Access Type File-level (NFS/SMB Block-level (iSCSI/FC)
- Network Standard Ethernet Fibre Channel / iSCSI
- Use Case File sharing, backupsMission-criticalapps
- Performance Good Excellent
- Complexity Low High
