Due to performance issues after an application migration, which storage solution is BEST to implement?

• A. Network Attached Storage (NAS)
• B. Direct Attached Storage (DAS)
• C. Deploy a new Fibre Channel SAN solution
• D. Use external USB storage

Answer: (C)

Choosing to deploy a new Fibre Channel SAN solution is the best approach for addressing performance issues that may arise after an application migration. Fibre Channel Storage Area Networks (SANs) provide high-speed connectivity and are optimized for high-performance applications. They allow for multiple servers to access a centralized storage pool efficiently, which is particularly crucial for applications that require fast data retrieval and high throughput. Fibre Channel SANs also support features such as load balancing and redundancy, which can enhance performance by distributing workloads across multiple paths and providing failover capabilities to ensure uninterrupted access. This is especially important in enterprise environments where scalability and reliability are paramount. In contrast, the other options may not provide the necessary performance improvements. Network Attached Storage (NAS) often operates over standard Ethernet and while it is user-friendly and easy to manage, it may not deliver the same speed and efficiency as a Fibre Channel SAN, particularly in high-demand scenarios. Direct Attached Storage (DAS) offers very good performance since it connects directly to a server, but it lacks the flexibility and scalability of a SAN solution, making it less suitable for environments where multiple servers need access to a shared pool of resources. Using external USB storage may provide convenience for small data transfers, but it is not designed for high-performance applications
