WHAT IS SAN (STORAGE AREA NETWORK)?
If NAS feels great but you’re running mission-critical systems, high-traffic databases, or virtual machines — this is where SAN comes in 💪
WHAT SAN DOES?
Dedicated high-speed network for storage
Provides block-level storage to servers
Appears to servers like local disks
Built for performance, reliability, and scale
Think of SAN as enterprise-grade storage designed for serious workloads.
WHAT YOU USE SAN FOR
Virtualization platforms (VMware, Proxmox, Hyper-V)
Databases (ERP, finance systems, high-IO apps)
Mission-critical applications
High-availability (HA) & failover systems
Large-scale data centers
SAN is all about speed + uptime.
HOW SAN WORKS
Servers → connect to → SAN network
SAN network → connects to → shared storage
Instead of accessing files, servers access raw storage blocks, just like internal SSDs but shared, redundant, and super fast.
WHY SAN IS POWERFUL
✓ Extremely fast (low latency)
✓ Centralized storage for many servers
✓ High availability & redundancy
✓ No single point of failure (when designed properly)
✓ Designed for 24/7 enterprise workloads
WHO SHOULD USE SAN?
Medium to large enterprises
Companies running many virtual machines
Data centers & cloud providers
Organizations where downtime = money
