SAN use cases

Storage area networks are good choices for the following enterprise environments and use cases:

  • Data centers with multiple storage systems that need to be connected on a network 
  • Organizations with multiple branch offices that need to pool stored data 
  • Multi-site backup procedures and recovery
  • Databases that support mission-critical workloads and data-intensive, rapid-access applications
  • Virtual environments that support high-performing applications, rapid I/O requirements, and scalability 


Network-attached storage allows businesses to store and pool large numbers of files and access them in a single location. NAS is particularly beneficial for enterprises with heavy file storage needs. Examples include healthcare providers with customer medical records and financial services organizations that store forms. 

Additionally, NAS systems enable file sharing between devices. If your teams consistently share files, NAS is beneficial. Scale-out NAS systems can also be useful for big data storage and analytics, though you’ll need a high-performance system for any mission-critical big data applications. Note that NAS systems transmit data more slowly than SAN overall. 

Broadly speaking, NAS devices and systems are less expensive than a SAN. While this can vary depending on the size and quality of the NAS versus the SAN, NAS tends to be a more affordable solution, as well as easier to deploy.

Storage area networks are beneficial for enterprise-grade backup procedures. SANs help businesses back up storage systems that are on the same network. Although backing up the entire SAN takes time and system memory, it also allows organizations to store a whole network’s worth of data in remote data centers. Although this level of backup requires significant time and system resources, it’s an important feature for large businesses with multiple storage arrays. 

SANs can also support databases that hold data for mission-critical applications. Because of storage networks’ low latency, they can meet the quick access requirements for databases that support organizations’ most data-intensive workloads. SANs typically have lower latencies than NAS systems.   

Some organizations use both NAS and SAN depending on their storage needs.

How to choose a SAN vendor

To select a SAN vendor, consider how its features, integrations, and management capabilities can fit your specific business needs. The following selection criteria will help your organization narrow down suitable SAN arrays:

  • Evergreen: Look for SAN solutions that can be non-disruptively upgraded for added capacity, faster performance, or new software capabilities.
  • Simplicity: Ease of deployment, operations and management are essential in an age when few want to invest in a team of storage management experts. 
  • Integration: Look for automation and integration with leading hypervisor, container, and orchestration platforms via industry standard APIs
  • Performance: Fast and consistent performance in the form of low latency and non-disruptively scalable controllers enable businesses to run without disruption.
  • Efficiency: Data reduction includes built-in compression, deduplication, and thin provisioning. 
  • Security: This should include built-in encryption of data at rest as well as the ability to encrypt data in motion.
  • AIOps: AI-generated support and proactive recommendations make sure applications run smoothly, minimize any business disruption, and reduce the need for specialized storage expertise.
  • Portability: Ease of data portability between on-premises and cloud helps workloads receive consistent enterprise-grade data services.

Bottom line: SAN storage solutions for businesses

Storage networking helps businesses pool data from multiple storage systems, decreasing information silos, and use that data to support their most important applications. Modern SAN technologies like NVMe-oF allow organizations to rapidly share data across large environments like data centers. 

Although SAN storage solutions require both personnel and financial investment to successfully implement, they’re worthwhile for enterprises with virtual environments, large databases, and intensive backup procedures. Consider one of our picks for SAN setups if your organization needs a more efficient way to transfer and store data.
