SAN Storage Usage Tips – Boost Your Data Center’s Performance

 SAN Storage Usage Tips – Boost Your Data Center’s Performance

Data storage is one of the most critical elements of any data center, and with the growing demand for storage capacity, the use of SAN (Storage Area Network) has become increasingly popular. SAN storage offers high performance and flexibility for enterprise storage needs, but it can also be a complex and tricky technology to use. In this blog post, we will discuss important tips and best practices for using SAN storage efficiently, allowing you to get the most out of your data center’s performance.


Set Up a Backup and Recovery Plan

Data loss is a catastrophic experience, especially when important business data is stored on the SAN. To ensure that your data is always protected, it is essential to have a backup and recovery plan. Frequent backups can protect data from hardware and software failures, cyberattacks, and any unanticipated disasters. Implementing a disaster recovery plan and testing it regularly could minimize downtime and data loss during unforeseen disasters or failures.


Utilize Tiered Storage

Utilizing tiered storage can help in maintaining the aging data. It is common for SAN storage to contain different types of data – some of which have not been accessed for a long time. Storing all data types on the same disk can affect system performance, but with tiered storage, users can move less frequently accessed data to slower, less expensive disks, freeing up space and optimizing system performance. When data is moved to lower cost tapes or disks, there are cost savings and storage capacity benefits.


Ensure Proper Maintenance and Monitoring

Regular maintenance and monitoring are crucial to maintain the performance and longevity of SAN storage. Routine maintenance includes firmware upgrades, patching, tuning, defragmentation, and more. Monitoring solutions such as performance and capacity management tools help IT teams to identify system bottlenecks, track trends, and allocate resources appropriately.


Implement Quality of Service (QoS) Settings

In a shared SAN environment, it’s essential to ensure that the applications have adequate resources and priority access to the storage I/O required. Implementing Quality of Service (QoS) settings allows administrators to control and prioritize application access to the shared SAN storage, reducing the risk of performance degradation due to other applications’ activities.


Keep Full Disk by Removing Unused Data

Once the SAN’s disk performance starts to degrade, you will notice slow response times, slower application performance, and overall slow system performance. It’s a good practice to delete or remove all the unused data on the primary disks, which will allow optimal read/write operations. Once you have deleted or moved data to lower-tier storage, you can defragment the disk for optimal performance.



SAN storage provides high-performance, scalable, and flexible storage solutions. Following the above tips and best practices will help plan maintenance schedules, ensure proper monitoring, and improve overall system performance. The utilization of tiered storage, Quality of Service (QoS), and full disk management will all play a significant part in optimizing system performance. Choose your SAN storage wisely, and remember, maintenance is key to the health and longevity of your data center’s system. With these tips, your data center’s SAN solution will be on its way to delivering an efficient, dependable, and highly performing system.
