Network-Attached Storage (NAS) and Fibre Channel (FC) are two different storage architectures, each with advantages and disadvantages.
Disadvantage of NAS Compared to Fibre Channel:
Lower Performance and Scalability:
- NAS relies on TCP/IP over Ethernet, which introduces higher latency and lower throughput compared to Fibre Channel, which is optimized for high-speed, low-latency storage access.
- NAS may experience bottlenecks due to network congestion and shared bandwidth, making it less ideal for high-performance applications.
- Fibre Channel, on the other hand, operates on a dedicated storage network, providing higher speeds, lower latency, and better scalability.
