Storage Connectivity
Question
Which of the following is an advantage of an iSCSI SAN over a FC SAN?
Options
- AHigher performance
- BHigher scalability
- CLower latency
- DLower implementation costs
Explanation
An iSCSI SAN's primary advantage over a Fibre Channel (FC) SAN is its significantly lower implementation costs.
Common mistakes.
- A. Fibre Channel SANs generally offer higher performance and lower latency due to their dedicated, lossless protocol and network infrastructure.
- B. While both can scale, Fibre Channel often provides greater scalability for very large, high-performance enterprise environments.
- C. Fibre Channel SANs typically exhibit lower latency because they operate over a dedicated network using a native storage protocol, avoiding the overhead of TCP/IP.
