SolarWinds Storage Resource Monitor – Review 2022

We’re living in an era of big data. Consequently, organizations rely on data storage more than ever. Storage environment management and monitoring have, therefore, become an important part of many system administrators jobs. Fortunately, tools exist to make this an easy task. One such tool is the SolarWinds Storage Resource Manager and we’re about to give you an in-depth review of this full-featured product. No matter why you need a storage monitoring tool (to ensure flawless operation or to avoid running into capacity issues) this great product is almost certain to have something you need.

Before we have a look at the SolarWinds Storage Resource Monitor, we’ll briefly discuss storage resource monitoring in general. We’ll then briefly pause to explain what the SAN and NAS acronyms mean. The difference is subtle but important. After that, we’ll talk about some of the components typically found in storage monitoring tools. Once we’re all on the same page, we’ll have a detailed look at the product. We’ll present some of the tool’s main features and benefits. Next, we’ll talk about the Orion Platform, the foundation on which the SolarWinds Storage Resource Monitor rests before we discuss the tool’s requirements and pricing

About Storage Resource Monitoring

Storage monitoring mainly serves two purposes. On one hand, it is used to ensure that your storage environment is running smoothly, that all required volumes are available and that all storage resources are performing within their expected range. On the other hand, another typical use for storage monitoring is capacity planning. We all know that 1) storage is not an infinite resource and 2) one will eventually run out of it. Capacity planning is the act—or should I say art—of making sure we never run out of space.

Monitoring storage for availability is relatively simple. Once a tool is aware of where the storage resources are located and how to access them, it is a trivial task to periodically pool them for availability. Monitoring performance can prove to be a tad more complex. It is not really that complex but it requires that data transfer tests be performed. At first glance, it’s easy to figure that all that’s needed is to time the copy of a known amount of data. The downside of this is that copying any significant amount of data—an amount that is large enough to provide meaningful data—can adversely affect performance. Not only can it skew the measurements but it could also impact regular users.

NAS & SAN – A (Very) Quick Primer

Years ago, the storage scene was very different from today. Data was typically stored on large computers called file servers. They had large disks and could hold a lot of data. Technology evolved and RAID (Redundant Array of Inexpensive Disks) arrays started to appear adding some much-needed protection against disk failure. Today, things have changed quite a bit and most storage needs are addressed using either SAN or NAS technologies.

Let’s start with the NAS technology. NAS stands for Network Attached Storage. In fact, it is not much different from the file servers of yesteryear. It is a special computer that is attached to the network—hence the name—and that offers storage resources to remote computers. Contrary to a file server, they tend to run specialized feature-reduced operating systems and they offer no other service besides storing files. Most of them boast some type of RAID disk controller and they have varying expansion capabilities.

SAN technology—which stands for Storage Area Network, a play on word with Local Area Network—is completely different. A SAN has no processing function. It does nothing but store data. As such, it can’t be used by itself. You can think of a SAN as a bank of external disks for remote computers.

In a SAN environment, servers—be they file servers, database servers or any type of servers—have SAN controllers instead of disk controllers. Those controllers connect—usually via fibre optics cabling—to the SAN. Some SAN-based environments have completely diskless servers while others have local disks for storing their OS and used SAN disks to store data.

Components Storage Resource Monitoring Tools

Every storage monitoring is unique. In fact, every software product is unique. Many are similar but they all have little differences. Each one has specific features that no other has. This is also true for storage monitoring systems. Although each tool review below is widely different from the others, they all share a few common features.

The various components of storage monitoring tools are actually not much different from those of any other type of monitoring tool such as LAN monitoring. In fact, many will use similar technologies such as SNMP to poll the monitored devices. So, the first component of any monitoring tool is its polling engine. It is responsible for connecting to each monitored device and fetches its operational parameters. Some polling engines rely on a local agent running on the monitored system to gather information while others are agentless and use standard protocols like WMI or SNMP.

Another typical component of storage monitoring systems is some sort of database. What use would there be in collecting operational data if it were not kept somewhere? For this function, some systems rely on external databases like Microsoft SQL Server, Oracle or MySQL while others use either their own built-in database or a local flat file.

What good is the collection of operational data is it’s not shown anywhere? This is why some sort of dashboard is another essential component of monitoring systems. Most of them use a web interface and the best ones come with a fully customizable dashboard. Some will even allow different dashboard components for different users.

When a monitored parameter goes out of range or reaches a critical threshold, you most likely want to know about it. Storage monitoring systems typically have some form of alerting component that can flash a message on the dashboard or send a notification via email or SMS messaging. Some will even execute remediation scripts in reaction to events.

The last major component of storage monitoring tools is reporting. Various reports can be made available that show the state of the storage environment to executives or that demonstrate some type of regulatory compliance to the proper authorities.

Main Features Of The SolarWinds Storage Resource Monitor

The SolarWinds Storage Resource Monitor is truly a feature-rich product. It has monitoring (of course) but also capacity planning as well as alerting and reporting, just to name a few. Here’s an overview of some of the most important features of this excellent product.

Unified Storage Monitoring

Understanding the health of your storage devices from different vendors can be challenging. Storage admins need to juggle multiple tools to ensure that the storage devices and systems are all functioning as they should. With a unified storage monitoring tool like the Storage Resource Monitor, you can have visibility into all your storage devices from a single tool. Its home dashboard gives you an at-a-glance view of key storage metrics, such as usable capacity, raw disk summary, and highlights storage with performance risks. It can also provide a list of alerts that need immediate attention and action.

Storage Performance Monitoring

The tool’s primary purpose is to provide SAN and NAS performance monitoring and alerting to help you eliminate performance bottlenecks in your data center. In addition, the unified view into storage performance can help simplify key tasks that are otherwise tedious and complex, including managing storage space consumption on RAID groups, mapping storage volumes back to the host, and understanding how volumes are load balanced across storage arrays. It can help you determine whether all the objects in your storage environment are performing at their best or not. With the help of this tool, you can identify poorly performing LUNs, RAID groups, and disks.

Detailed Dashboards

The SolarWinds Storage Resource Monitor can help you navigate across all layers of storage, including arrays, storage pools, and LUNs. With just one click, you can seamlessly move from one layer to another. Each of these individual storage layers has a detailed dashboard that shows critical metrics indicating performance and health. With these features, you can quickly troubleshoot performance problems by isolating the actual hot spot and reducing unexpected downtime.

Automated Storage Capacity Planning

The storage capacity function in the SolarWinds Storage Resource Monitor is designed to track usage over time to help identify capacity issues in the array. You can also easily view growth trends and receive a forecasted view of when capacity will be reached. This helps administrators to plan when to add and when to re-allocate capacity. The tool can also reduce the complexity of storage capacity planning in both your virtual and physical infrastructure. Go deeper into the performance of datastores allocated to specific virtual machines in your environment. Trace dynamic relationships from apps, virtual machines, LUNs, pools, and arrays to discover capacity issues and whether the latency is really caused by storage performance. Identify which virtual machines are affected by storage issues, and take necessary steps to proactively prevent virtual machine downtime.

System Requirements

Like most products based on the Orion Platform, the SolarWinds Storage Resource Monitor requires two servers in all but the smallest installations. One server hosts the application while the other hosts the SQL database. Although both servers could be virtual and run on a single physical host, the SQL server’s database must reside on a separate, physical drive.

The hardware requirements are relatively complex as they vary according to the size of the installation one is contemplating. Rather than trying to describe every possible use case—and there are quite a few—we prefer to direct you to the SolarWinds website where the requirements are clearly laid out. Optionally, contacting SolarWinds sales would also allow you to ensure you correctly size your servers while accounting for eventual growth.


Pricing for the SolarWinds Storage Resource Monitor is based on the total number of physical disks you need to monitor. The product is available in nine licensing tiers that support between 25 and 5 000 disks. Prices start at $2 995 for up to 25 sockets. If you need to monitor a very large environment with over 5 000 disks, custom licenses can be arranged by contacting SolarWinds sales. You can also take the product for a test run before purchasing it as a free fully-functional and disk-unlimited 30-day trial is available.
