Business Benefits of Implementing a Storage Area Network


As technology becomes more sophisticated, enterprise storage demands are steadily increasing. Both large and small businesses are constantly adopt network storage technology to improve server performance and simplify data management processes.

Regardless of the growth stage of your business, adopting network storage instead of storing your data on hard drives has many advantages. Typically, a storage area network acts as a reliable file server, making documents and data available throughout your enterprise. Most importantly, it provides a central point for data storage and backup in the event of a devastating disaster for your business. Here are some things you need to understand about the business benefits SANs.

Superior disk utilization capabilities

The key advantage of the storage network is the top disk usage. Unlike direct attached storage (DAS) which has limited disk usage, SAN systems can achieve optimal disk utilization. Storage arrays in SANs are interconnected through a centralized storage network, allowing the infrastructure to be managed as a single storage unit.

This feature allows your organization to aggregate different pools of storage resources at the network level based on the needs of each server. Missing out on SAN technology means your business has to buy a range of different disks and attach them directly to the server, which still leaves you with below-average disk usage issues.

On the other hand, SAN storage models are designed with multi-tenant capabilities in mind. This means they can easily handle multiple workloads, so you don’t have to limit system administration to a few people on your team.

Data security and recovery

The SAN solution helps your business quickly implement critical security measures to improve data security and privacy. For example, you can isolate various types of data based on departments, users, and organizations to improve data management.

Additionally, you can establish access control lists to ensure that only authorized people have access to specific data. Ideally, default SAN algorithms are designed to protect all data on the network and ensure that security protocols are implemented on all servers, an essential feature in security-focused applications.

When you have mission critical servers in your data center that need to be running all the time, having a data continuity solution is essential. In the event of a disaster, the system acts as your failover, as SAN-based disaster recovery solutions are a solid choice. Regardless of your industry, downtime can make or break your business, and that’s unacceptable in a digital business landscape. Generally, SAN models can significantly reduce downtime, so Imitigate potential losses.

Storage networks support specific enterprise applications that require high availability. However, scenarios can arise down the line where certain applications fail due to faulty hardware or data corruption. The SAN array design ensures data consistency by implementing defined data protection algorithms for optimal performance.

Fast and centralized backup

Data backup is often an important consideration when ask for opinions on the performance of your network. Using a storage area network ensures efficient access and transfer of corporate data. If a server disconnects, the next server takes over and automatically stabilizes data loads. This capability makes the system more flexible and simplifies administration. SAN design achieves this by ensuring that there are no cables or storage devices to move, improving storage utilization and efficiency.

Businesses constantly generate large amounts of data and maintaining reliable backups is essential. Slow data backup solutions may be insufficient in a rapidly changing digital business landscape. SAN eliminates this problem with its ability to rapidly duplicate data. This means your IT admins can back up data seamlessly and frequently.

Specifically, it is easier to back up data from different enterprise systems while controlling servers from a central platform. Management issues and data availability also increase when you eliminate storage silos.

LAN Redundancy and Bandwidth

SANs come with redundant disk arrays that servers recognize as local storage volumes. This feature facilitates exceptional availability and fast I/O performance levels compared to other storage technologies.

SAN technology promotes a significant improvement in bandwidth. On the other hand, LAN-based storage systems are plagued with bandwidth bottlenecks, which hamper system performance and compromise the execution of simple tasks. By offloading a significant amount of network traffic, the SAN reduces pressure on LAN bandwidth.

Speed ​​and scalability

SAN designs provide better performance than other technologies such as NAS systems. Typically, the NAS routes data storage over a local area network. Although these systems can be relatively inexpensive and often consist of a few hard drives, they are slow because they are subject to network bandwidth constraints. Nonetheless, NAS systems are still popular for smaller enterprise environments that need general-purpose data storage platforms.

On the contrary, SANs are specialized systems designed for robust data storage. Instead of routing data traffic through a LAN, a SAN uses a Fiber Channel connection to send data traffic. This means that your servers have direct block-level access to SAN storage systems. The end result is performance beyond what you can get with similar storage technology solutions.

Similarly, storage networks offer better scalability based on your business needs. If your organization exceeds its current storage needs, you can easily add more disks to your system. And while the number of additional disks is limited, most SAN systems can accommodate thousands of disks and maintain peak performance. This means you don’t have to overhaul your entire system every time your storage needs increase.


Storage Area Networks are versatile, reliable, and scalable high-speed storage solutions that connect multiple servers to a range of storage devices. SANs make access and storage more convenient by moving storage from individual servers and consolidating them into a central location where you can manage and protect data. Therefore, SAN solutions are excellent for IT departments in various organizations and businesses.

Whether you need a block-based storage solution to manage your database, traditional enterprise applications, or an option for complete cloud needs, SAN can be an excellent choice. However, it is essential to assess your organization’s needs before adopting SAN.
