Storage has become vital for all IT infrastructures with the increasing adoption of technologies like Big Data and virtualization. 

Many enterprises use multiple SAN devices and NAS storage to store essential information. 

And a failure or slowdown of the storage system can cause applications to turn off or fail, directly affecting the business. A simple outage can also lead to data loss, network failure, or slowdowns. 

This requires administrators to proactively detect issues, identify the cause of problems, and initiate corrective actions to keep the infrastructure healthy. 

Thus, it is important to monitor the physical health of SAN and NAS storage devices with advanced storage monitoring tools. 

Let’s dive deeper into storage monitoring tools and how they can help keep your storage systems in optimal state and the enterprise running. 

What Is Storage Monitoring?


Data storage nowadays is changing rapidly. Most of today’s enterprises depend on software-defined storage in the on-premises or cloud. So, keeping track of your storage requires monitoring to provide deeper visibility across your infrastructure storage. This is done with storage monitoring. 

Storage monitoring is a process of monitoring, evaluating, and managing on-premises, virtual, and cloud-based storage systems. It allows you to view the issues regarding critical applications while monitoring several elements associated with the applications. 

Storage monitoring tools are software offering a wider view of your administrators so that they can take proactive actions to predict, diagnose, and resolve issues in a smarter way. This will improve the end-user experience and device performance. 

Features of an Ideal Storage Monitoring Tool

Storage management solutions offer a wide variety of features. The important features that a storage monitoring tool provides are:

  • Data management
  • Storage provisioning
  • Storage solution visibility
  • Array availability, capacity, and performance
  • Data volumes and status
  • Alerting
  • Storage analysis
  • Advanced graphs
  • Infrastructure management
  • Capacity planning
  • Configuration wizards

Benefits of Storage Monitoring

Storage monitoring tools can help you evaluate the following:

  • The performance and health of device ports, controllers, disk groups, physical disks, LUNs, and more
  • Storage capacity so that the resources can be used for maximum performance
  • The density of traffic on the disk groups
  • External hosts that handle the maximum number of requests
