CompTIA Server+ (SK0-005)Server Hardware Installation and ManagementMedium
A server administrator is configuring a new storage array for a virtualized environment that requires high throughput and low latency for database applications. The array will connect to multiple hypervisor hosts. Which storage connection technology would provide the BEST performance for this scenario?
- ASATA direct-attached storage
- BiSCSI over 1GbE
- CFibre Channel (FC)
- DNFS over 10GbE
Show answer & explanationAnswer & explanation
Correct answer: C. Fibre Channel (FC)
Fibre Channel (FC) is a dedicated high-speed network technology designed specifically for storage area networks (SANs). It offers significantly higher throughput, lower latency, and greater reliability compared to Ethernet-based storage protocols like iSCSI or NFS, making it ideal for demanding applications such as databases in virtualized environments.
Why the other options are wrong
- A. SATA direct-attached storage is not a network-based solution for shared storage across multiple hosts.
- B. iSCSI over 1GbE can be a bottleneck for high throughput and low latency requirements.
- D. NFS is a file-level protocol and, while 10GbE improves speed, it generally has higher latency than block-level protocols and FC.
Fibre Channel (FC)
A high-speed network technology primarily used for Storage Area Networks (SANs), providing block-level data access with low latency and high throughput.
- Dedicated storage protocol
- Block-level access
- High performance and reliability
Memory trick: FC is fast for SAN, iSCSI is IP's plan, NFS shares files, DAS is just one man.
