Best Storage Monitoring and Management Tools and Software for SAN and NAS Devices

Best Storage Management Software for monitoring San and Nas Devices

Marc Wilson UPDATED: July 25, 2023

Just about every professional/business environment needs Storage (as many of you know, more of it) – whether just for emails and correspondence or for far more important performance-critical digital applications, websites, hosted files, file servers, exchange servers or SAN Devices – it would be hard to overstate the importance of storage management and monitoring due to this!

Both smaller networks simply operating from a NAS-storage basis and larger, multi-network environments running multiple SAN devices need proper monitoring.

An untimely outage, failure due to lack of storage, or poor response time due to over-subscription can all cause expensive problems if not downright showstopping failure!

Here is our list of the best storage monitoring and management tools:

When dealing with managing NAS/SAN storage devices, there's a lot to bear in mind.

Software which can monitor capacity, as well as assist in assigning it to various applications, can save a great deal of time and headache by predicting and being aware of needs early on.

Monitoring hardware for failures and outages helps to keep tabs on the physical health of the ever-important storage devices.

Keeping track of latency can be one of the best indicators of an aging drive or failing device, while also helping to keep tabs on the management of bandwidth use to and from storage devices.

And of course there's over-subscription, a clever but precarious method for making the most out of your network that works very much in the same vein as overbooking flights like airlines tend to practice, but it does come with its risks and software can thankfully help manage those!

Monitoring software needs to be able to keep a close eye on every part of your storage arrangement – whether simple and single systems running as a NAS, or independent SAN devices like tape drives or their ilk, and of course you can't leave LUNs out in the dark!

Especially in larger enterprise setups you've got to have robust LUN monitoring and oversight to be sure that your RAIDs are properly allocated and made full use of.

No matter the make-up of your network storage devices, whether Dell, EMC, HP, WD or others, many tools can poll and monitor these devices and even aggregate device-specific data to help keep you, and your network, up to speed.

4. ManageEngine OpManager + Applications Manager – Download Free Trial

manageEngine opstar software

ManageEngine offers a suite of system monitoring and management tools. Each module can be used as a standalone system but they are all written on a common platform and interconnect, so combining tools provides extra strength. This is the case with OpManager and Applications Manager. These two utilities combine cover all of your system from applications and websites through to servers and network devices.

OpManager was built to supervise network devices and servers. This is a hardware monitoring system that gives you automated performance tracking and status supervision for all storage devices, such as SAN and NAS systems. This tool traces network performance, too, so it can identify if an apparent problem with storage access is really caused by an intermediate device on the path between management software and physical servers.

Storage is not an island and you will be running applications that make constant, repeated access to those NAS and San systems. Applications Manager checks that requested data is delivered up to the application in a timely manner. So, you can head off problems before they become noticeable to users by tracking performance of the entire protocol stack up from Layer 2 to Layer 7. The performance of networks, servers, and storage facilities is no longer just a site infrastructure issue. OpManager and Applications Manager reach out across the internet and check on the availability, delivery speeds, and performance of cloud resources as well. While OpManager checks on connections to cloud storage, Applications Manager constantly monitors cloud storage facilities and watches cloud services and server performance.

OpManager and Applications Manager take care of all monitoring tasks automatically. Both systems include an alert mechanism that lets you know when trouble arises. These alerts can be forwarded to you and your team through email and SMS message. That lets you get on with the job of managing resources without having to sit watching system monitoring consoles.


  • Designed to work right away, features over 200 customizable widgets to build unique dashboards and reports
  • Leverages autodiscover to find, inventory, and map new devices
  • Uses intelligent alerting to reduce false positives and eliminate alert fatigue across larger networks
  • Supports email, SMS, and webhook for numerous alerting channels
  • Integrates well in the ManageEngine ecosystem with their other products


  • Is a feature-rich tool that will require a time investment to properly learn

The software for OpManager and Applications Manager is available for installation on Windows Server and Linux. ManageEngine doesn’t offer a combo of these two services, but buy both and they will slot together. You can put this partnership to the test with a 30-day free trial of OpManager and Applications Manager.

5. Nagios

nagios monitor

Storage Monitoring with Nagios is a great piece of software that offers a staggering range of flexibility and functionality – mostly due to being highly modular! SAN/NAS and other storage management and monitoring requires additional plugins from the base Nagios software, but once installed Nagios can more than pull its weight in this regard.

Furthermore, as it requires the base Nagios installation, you gain the benefit of having a robust network monitoring suite to begin with!

As far as storage management, though, Nagios covers all the bases you'd want, plus gives a lot of flexibility with plugins and addons to customize or change precisely what, or how, you monitor.


  • Open-source transparent tool
  • Simple, yet informative interface
  • Flexible alerting options support SMS and email
  • Robust API backend makes it a great option for developers who want to integrate their own custom applications


  • Would like to see additional integrations into more ticketing systems
  • Installation can be technical and complex

Free trial, starting at $1,995 and up, some plugins/modules have additional cost/licensing

6. AppDynamics Storage Performance Monitoring


AppDynamics is a very solid “all in one” option that attempts to cover the full range of network-based monitoring and management.

With options for everything from application, transactions, services, nodes, servers, database calls, remove services, and of course storage and even more, the program has a staggering range of tracking.

This does come with the usual caveat – with breadth comes slightly less depth, and although AppDynamics doesn't suffer as much from this as some software options, you may find some more niche or specific features missing or lacking slightly.


  • Tailored for large-scale enterprise use
  • Excellent dependency mapping and visualizations to help troubleshoot complex application systems
  • Includes a free version
  • Includes root cause analysis tools


  • Priced higher than similar tools on the market

7. PowerAdmin Storage Monitor

pa storage monitor pro console

PowerAdmin has a reasonably light-weight and straightforward option that focuses almost exclusively on storage management alone with very few other bells and whistles – which isn't necessarily a bad thing! It scans and catalogs, reports on files, has predictive disk usage, monitoring and alerting, and so forth.

The focus is more on file management as well as device management and would be better used by network environments with a lot of data that needs managing as well as space and some of the device managing options fall a little short, but overall it's a solid option!


  • A lightweight tool, takes up very little space and system resources
  • Supports testing multiple hosts at the same time
  • Uses threshold-based alerting to keep repeat alarms to a minimum


  • Must reach out to sales for a quote, pricing not transparent
