It has the ability to tailor tiers according to what we need and put the right services in the right place
Pros and Cons
- "It is very easy to scale, so we started with a four-node cluster and added it to a six-node cluster. We've also done some other modifications in between."
- "One of the things that we were looking at being able to do a FlexGroup NFSv4. Right now, 9.4 goes up to NFSv3, but if we could get the NFSv4 solution on a 9.4, or a future release, that would be awesome."
What is our primary use case?
How has it helped my organization?
It makes our organization more efficient with more scale. We have the ability to tier off the storage and ensure storage is efficiently utilized so we can get rid of idle data and data that is not required. Then, we can show and prove what needs and should be used.
We do use this solution for mission-critical applications.
What is most valuable?
Its flexibility is its most valuable feature. It has the ability to mix with the different requirements that we have to provide, such as some I/O intensive services and a lot of archive services. It has the ability to tailor tiers according to what we need and put the right services in the right place.
What needs improvement?
One of the things that we were looking at being able to do a FlexGroup NFSv4. Right now, 9.4 goes up to NFSv3, but if we could get the NFSv4 solution on a 9.4, or a future release, that would be awesome.

Learn what your peers think about NetApp ONTAP. Get advice and tips from experienced pros sharing their opinions. Updated: September 2025.
870,697 professionals have used our research since 2012.
What do I think about the stability of the solution?
Stability is great. We have a six-node cluster. We've done head swaps. We've had failures and the cluster has always stayed up and the data has always been available. We haven't lost any data either.
What do I think about the scalability of the solution?
It is very easy to scale, so we started with a four-node cluster and added it to a six-node cluster. We've also done some other modifications in between.
This solution helped our organization reduce our overall cost of storage. Because idle data which was residing on high cost tiers, once we sifted the ONTAP, we were able to scale and place it where it should be, then offload the data which was unnecessary to different locations.
How are customer service and support?
Technical support is awesome. We call them up, and they're there. We receive answers and get what we need right away. We have four hour delivery, as it's based on our contracts, but we do receive outstanding support.
How was the initial setup?
The initial setup was pretty straightforward. There was a guide of how everything goes together. Therefore, use the guide, put it together, and you're up and running.
What about the implementation team?
During the initial install, we had a reseller who came in, helped us build it out, etc. They were awesome getting us up and running. Now, that it's up and running, even though they don't have access to our systems, but we can still call them and get assistance, look into different changes, opportunities to scale in or our, and upgrade as we need to.
What was our ROI?
We have been able to save space by using the solution.
What other advice do I have?
Look into the product's reliability. You will definitely see an increase in your business performance if you use it.
We don't current employ any NVMe. We have SSD. We're looking at NVMe potentially on some of our higher IOP operations, but we don't deploy it right now.
We use SaaS and also have a Hadoop cluster which are backed up by ONTAP storage. These are for doing a lot of data analytics and analyzing different data streams. AI is soon to come.
Disclosure: My company does not have a business relationship with this vendor other than being a customer.

Storage Engineer at a aerospace/defense firm with 1,001-5,000 employees
It has been very stable. Our mission-critical applications are on it.
Pros and Cons
- "It's much easier and faster to deploy our storage with ONTAP than some of the other solutions that we have."
- "We can do upgrades without taking it down. We have had nodes fail and people just kept working."
- "We would like to have additional cloud integration and the ability to Snapshot directly to Amazon. This would help us reduce costs, provide us additional disaster recovery, and give us a site that's not owned by us."
What is our primary use case?
Our primary use case is network-attached storage.
How has it helped my organization?
It's much easier and faster to deploy our storage with ONTAP than some of the other solutions that we have.
We use it for everything from payroll to home directories.
What is most valuable?
- Availability
- Resiliency
- Ease of use
It stays up. My people can easily manage it. It just works for us. It has been very stable. Upgrades have worked. We've had very minor to no real problems with it.
What needs improvement?
We would like to have additional cloud integration and the ability to Snapshot directly to Amazon. This would help us reduce costs, provide us additional disaster recovery, and give us a site that's not owned by us.
What do I think about the stability of the solution?
It has been very stable. Otherwise, we wouldn't have put our mission-critical applications on it.
We can do upgrades without taking it down. We have had nodes fail and people just kept working.
What do I think about the scalability of the solution?
It has scaled really well for us. We started off with several nodes and are up to about 16 node clusters now.
How are customer service and technical support?
Support has been great. We also have professional services in our offices, and our professional service guys have been awesome. They are super-fast in finding problems and fixing them.
Which solution did I use previously and why did I switch?
We switched solutions because were at capacity as far as size. NetApp was also cheaper and easier for us to deploy.
How was the initial setup?
The initial setup was very straightforward and simple. Put an IP on it, give it some passwords, and we configured from there with strips and other stuff.
What about the implementation team?
We deployed with an in-house. The experience was great. We had enough experience in-house that it worked.
What was our ROI?
This solution has helped our organization reduce our overall cost of storage. We're part of the NetApp OnDemand, where we lease it. Also, it doesn't take as many people to administer the solution as some other products.
Because of its manageability, we have fewer people managing it.
Which other solutions did I evaluate?
Our short list was Dell EMC and NetApp. NetApp was more familiar to our people, and they came in cheaper per gigabyte.
What other advice do I have?
It has been amazingly easy for us to use.
We hope will be using this solution for machine learning, AI, and real-time analytics in the future.
We are not using NVMe yet.

Learn what your peers think about NetApp ONTAP. Get advice and tips from experienced pros sharing their opinions. Updated: September 2025.
870,697 professionals have used our research since 2012.
Architect at a retailer with 10,001+ employees
Since we have a hybrid solution, we can accommodate for the performance that we need
Pros and Cons
- "It has been very stable. We haven't had a significant outage."
- "The solution has helped our organization reduce its overall cost of storage by allowing us to have multiple sites using the multi-tenant security model, segregated from each other, while at the same time using the same resources."
- "Sometimes, we have had some delays, on holidays and weekends, getting the right resource for a specific problem."
What is our primary use case?
We use it for SMB and CIFS for different departments. It is also used for HIPAA and FTC compliance.
How has it helped my organization?
Management, deployment, and compliance are much easier. We're doing NetApp Volume Encryption (NVE), so it has increased the security model as well.
We use ONTAP for our mission-critical applications. E.g., at our pharmacies, we started loading data onto our NetApp systems.
What is most valuable?
- Ease of use.
- Ease of expansion.
- It doesn't go down and is very reliable.
- It is quite fast.
- Since we have a hybrid solution, we can accommodate for the performance that we need.
What needs improvement?
We would like more building performance monitoring. Right now, we have to buy separate products.
What do I think about the stability of the solution?
It has been very stable. We haven't had a significant outage. We do take time and test as if we were going to go down, but we haven't gone down yet.
What do I think about the scalability of the solution?
Because we are using ONTAP Cluster Mode, if we want to increase, we add nodes or pairs of nodes. It is that easy.
How are customer service and technical support?
I would rate technical support as an eight of ten. Sometimes, we have had some delays, on holidays and weekends, getting the right resource for a specific problem.
When we need to escalate an issue, there can be a delay when they have to find somebody. Besides that, our experience has not been bad.
Which solution did I use previously and why did I switch?
We used and still use Dell EMC.
What about the implementation team?
We used NetApp for the deployment. Right now, we are using a VAR, World Wide Technology, for NetApp operations.
Our experience with World Wide Technology has been good. It's a fantastic company. Whenever we have had issues, if NetApp is not prompt, they almost immediately try to resolve them. They have their own resources. We have increased our support by having them as a middleman.
What was our ROI?
We have seen ROI, especially with the deduplication. We have a high ratio of deduplication and are way past 70 percent of our VDI, as we have almost 400TBs on our VDI. We have been able to save at least a quarter of a petabyte of space.
The solution has helped our organization reduce its overall cost of storage by allowing us to have multiple sites using the multi-tenant security model, segregated from each other, while at the same time using the same resources.
What's my experience with pricing, setup cost, and licensing?
Our cost per IOP is three to four dollars, but we have a hybrid solution. Therefore, we have SSD and spinning disk running together.
In the past, you didn't have to buy separate products. They were mostly included with the purchase. In the end, it's more expensive to buy it separate than together. If you are going to need it, one package at the beginning is cheaper.
I don't like this nickel-and-diming. I like an all in one solution.
Which other solutions did I evaluate?
NetApp is a lot better at replication and easier to set up for replication than its competitors.
Dell EMC is expensive in comparison to NetApp, but its reliable as well. We like them too.
We looked at Pure Storage and some other vendors, but were not convinced it was the direction that we wanted to go.
What other advice do I have?
Do a PoC and compared against your current solution. ONTAP is very intuitive.
We use the solution for analytics and monitoring. Our monitoring system uses both Splunk and Log Insight and the analytics are tie into NetApp.
We haven't used NVMe, but are looking forward to it. To my understanding, it is not ready yet to be implemented on NetApp or any other product. However, we're ready to start testing it as soon as the product's available.
Disclosure: My company does not have a business relationship with this vendor other than being a customer.
The technical support is the best that I have ever encountered
Pros and Cons
- "The technical support is great. It's the best I've ever encountered. I can email and have everything resolved at three in the morning within half an hour. I have had some late night calls to their guys techs, and it's been phenomenal."
- "I would like more diagnostic generation. Right now, it's a pain to go into the controller and do a full diagnostic and export."
What is our primary use case?
ONTAP runs our Tier 1 data center. We use it for running all our virtualization, backups, etc.
How has it helped my organization?
Where the DBA is doing all the migrations and testing within our database, we have Tier 1 and Tier 2 data centers and do a lot of testing across them. The ability to create a FlexClone and immediately test everything which needs to be done then revert back within minutes, if needed, is phenomenal for testing.
What is most valuable?
FlexClone has been great for R&D. We've been doing a lot of testing, implementing Oracle DBAs and getting them into the thick of things.
What needs improvement?
I would like more diagnostic generation. Right now, it's a pain to go into the controller and do a full diagnostic and export. If that could be streamlined in any way and not be so tedious, because it's a pain to go through all the different steps and have the command memorized or have to look it up. If there was some way NetApp could incorporate it into the native ONTAP command center, that would be great.
For how long have I used the solution?
Three to five years.
What do I think about the stability of the solution?
I've never had an issue with it. Same with the upgrades, we have had no issues from 8.2 to 8.3 to 8.4. The stability has been great for four years.
What do I think about the scalability of the solution?
We are in the process of doing a huge data center refresh. We will find that out very shortly about its scalability.
How is customer service and technical support?
The technical support is great. It's the best I've ever encountered. I can email and have everything resolved at three in the morning within half an hour. I have had some late night calls to their guys techs, and it's been phenomenal.
I probably leverage NetApp's engineers too much, but we have a good working relationship with their contacts. They usually handle everything within a few messages, so it has been great.
How was the initial setup?
The initial setup was straightforward for me. I am a storage engineer, so I'm familiar with it. Even our network engineers that have to set it up using NetApp diagrams had no issues with it.
What about the implementation team?
We have used CDW in the past. However, we are now going with NetApp directly.
CDW was great. We didn't have too many issues. However, for our work particularly, there wasn't a enough value-add to stick with a third-party. Therefore, we are now doing everything directly with NetApp.
What was our ROI?
I have seen ROI. NetApp is streamlined, reducing costs. ONTAP is the best.
What's my experience with pricing, setup cost, and licensing?
If you start narrowing down NetApp versus price point, then comparing it to the feature set and take away all the bloat that other companies will try to add on, there is no other option. It comes down to just NetApp.
Which other solutions did I evaluate?
We have some strict requirements because we are a defense contractor. It came down to NetApp and one other big company (Dell EMC). ONTAP's ease of use and our familiarity with it along with the reps, who are great about keeping us informed about training, etc. It made it a no-brainer for us to go with the solution.
We chose NetApp because of price and it's a no hassle solution. We're doing a trade study, so we asked all vendors for quotes, etc. We asked our NetApp reps, and they gave us what we needed within a timely fashion.
Dell EMC sent us eight people, who insisted on a two hour meeting. They keep trying to oversell us crap that we don't need. It felt very forced. Whereas our NetApp guys, they would rather undersell us than have us buy stuff that we don't need. I appreciate their upfront and honest attitude.
You can't switch out a hard drive without an EMC rep coming out, where NetApp is streamlined.
What other advice do I have?
There is nothing it can't do. It satisfies all my needs. It is straight to the point and has great updates.
We are doing a trade study right on all the things that we would like to have and everything we have hard requirements for, and NetApp meets both.

Pros and Cons
- "The scalability is very good. It enables us to use different product lines within the same operating system."
- "I would like to see more evolution towards the cloud."
What is our primary use case?
We use it for on-premise storage.
How has it helped my organization?
For our organization, in terms of resiliency, it has gotten better over the years. It has also become more reliable.
What is most valuable?
- Availability
- Resiliency
- Recoverablity
What needs improvement?
I would like to see more evolution towards the cloud.
For how long have I used the solution?
More than five years.
What do I think about the stability of the solution?
The stability is excellent.
What do I think about the scalability of the solution?
The scalability is very good. It enables us to use different product lines within the same operating system.
How are customer service and technical support?
Technical support is good to very good.
Which solution did I use previously and why did I switch?
We actually haven't switched. We've been using it for about 15 years. We've been with it for a long time.
How was the initial setup?
The initial setup was straightforward.
What about the implementation team?
We do all our deployments in-house.
Which other solutions did I evaluate?
We're always looking at different vendors, and we want to see fit-for-purpose. We want to make sure that we're using the right technology for the right job.
What other advice do I have?
It has a good, safe implementation.
I gave this product an eight, because there is always room for improvement and to make things better.

New features help us keep up performance but storage efficiency could be better
Pros and Cons
- "With the NetApp Data ONTAP Cluster, we get some features that are particularly helpful. For example, we can always add to and remove nodes from the cluster. The ability to move volumes online from the storage side, from one aggregate to another aggregate, or from one node to another node, keeps up the performance which helps us a lot."
- "Especially with the all-flash arrays, we would like to see better storage efficiency and deduplication. In terms of manageability, it would be great if NetApp would add more native reporting tools into the dashboard so that we don't need to use the third-party tool for analyzing our environments or to generate any reports. This would be especially helpful for companies that need to generate some chargeback for the customers."
What is our primary use case?
We are using the NetApp solution to host our tier-two storage workloads. We use it for virtualization and as a database for applications such as Microsoft Exchange, SQL, and Oracle.
What is most valuable?
With the NetApp Data ONTAP Cluster, we get some features that are particularly helpful. For example, we can always add to and remove nodes from the cluster. The ability to move volumes online from the storage side, from one aggregate to another aggregate, or from one node to another node, keeps up the performance which helps us a lot.
What needs improvement?
Especially with the all-flash arrays, we would like to see better storage efficiency and deduplication. In terms of manageability, it would be great if NetApp would add more native reporting tools into the dashboard so that we don't need to use the third-party tool for analyzing our environments or to generate any reports. This would be especially helpful for companies that need to generate some chargeback for the customers.
Vendors in the market are trying to simplify their technologies. They're working to make anything from the hardware and installation to the management of the array, simpler. And I think it would be great if NetApp worked to make the whole process simpler to help customers achieve their goals easier and faster. For example, NetApp could work to simplify tech refresh or migration. Some more reporting tool would be great as well.
What do I think about the stability of the solution?
It's been stable. We've been using NetApp for a long time and we've never really had any major issue with it.
What do I think about the scalability of the solution?
Scalability is good. The older Data ONTAP 7-Mode scalibility was a bit challenging. Clustered ONTAP is scaled-up technology since you can always add the node to the cluster.
How are customer service and technical support?
We have been NetApp customers for a long time. For the most part, we're receiving good support. Sometimes there are situations in which we need help from our NetApp rep, SE, or someone who knows how to escalate the cases for faster support. But our overall experience with their support is good.
Which solution did I use previously and why did I switch?
We always do our due diligence, whether it's a tech refresh or just moving on with another new project. We compare different technologies based on our requirements. Often when we have a chance, we also perform a PoC. We bring that technology into our data center and then we perform our tests on it. We have scorecards and then we go through every aspect based on our requirements, our customers, and project needs. Then we decide if it makes sense to move on with a new technology or product.
What about the implementation team?
We used NetApp themselves as well as a company called Red8.
What other advice do I have?
Instead of just considering the brand name, whether it's NetApp or any other vendor, my advice is always for a company to define their requirements. Once the requirements are identified, set the expectations and then consider NetApp as a possible solution because we have worked with it and have had a positive experience. If the data is consistent, my advice would be to move on with NetApp.

SAN Engineer with 1,001-5,000 employees
The new automation feature saves us a lot of time. The response time for tickets is bad.
Pros and Cons
- "The product is good at deduplication. Also, the new automation feature is good, as it saves us a lot of time."
- "Technical support is not in person nowadays. We have to wait a long time to get an engineer. Then, most of the time, their engineers are not good enough to understand our problems. While we might not be able to explain the problem well, or they are not able to understand the problem well, their solutions are slow to resolution. The response time for tickets is bad nowadays."
- "I need to be able to validate how the host is performing from the storage, as I am concerned about the host performance and storage connectivity to the host."
What is our primary use case?
We use it for the NAS solution. We have a NAS infrastructure with NetApp ONTAP.
How has it helped my organization?
The product is good at deduplication. Also, the new automation feature is good, as it saves us a lot of time.
What is most valuable?
- SnapMirror
- SnapVault
- Deduplication
- The compression.
What needs improvement?
I need to be able to validate how the host is performing from the storage, as I am concerned about the host performance and storage connectivity to the host.
They have to improve on the data and monitoring tools.
What do I think about the stability of the solution?
The stability is good. They have point in time recovery, and they don't have any single point of failures.
The FAS series is good. In addition, they have around 10Gs for management, which is nice.
What do I think about the scalability of the solution?
I love NetApp's scalability. We started in three areas, and now, we have grown to 16 areas. It is that good at scaling.
How is customer service and technical support?
Technical support is not in person nowadays. We have to wait a long time to get an engineer. Then, most of the time, their engineers are not good enough to understand our problems. While we might not be able to explain the problem well, or they are not able to understand the problem well, their solutions are slow to resolution. The response time for tickets is bad nowadays.
How was the initial setup?
Half of the setup is straightforward. However, when we want to do customizations and networking configurations, it is quite challenging. The issue is that we cannot fit NetApp's configurations to our organization standards.
What about the implementation team?
We have a NetApp consultant for all types of deployments. He has been wonderful to work with as he is always helpful.
Which other solutions did I evaluate?
The top two vendors that we considered were NetApp and Dell EMC.
We are also considering some white labels for HCIs, but these solutions aren't shortlisted yet.
What other advice do I have?
If you need something in the NAS area, consider or test the NetApp products.
On the storage and box side, NetApp is really good at what they do.

Executive Director at a financial services firm with 10,001+ employees
The initial setup and deployment were straightforward
Pros and Cons
- "The initial setup and deployment were straightforward"
- "The vendor diagnostics, which allows for movement from one vendor to another vendor using the application technology that is available. It should be able to talk to any vendor, not just NetApp to NetApp. We should be able to replicate the data, so the next feature should not be vendor specific."
What is our primary use case?
The primary use case is to move from Fibre Channel to SolidFire.
How has it helped my organization?
We see it drastically improving our organization. We are trying to move away from Fibre Channel. SolidFire with iSCSI will change a lot going forward in the organization.
What needs improvement?
The vendor diagnostics, which allows for movement from one vendor to another vendor using the application technology that is available. It should be able to talk to any vendor, not just NetApp to NetApp. We should be able to replicate the data, so the next feature should not be vendor specific.
What do I think about the stability of the solution?
The solution is stable, and upcoming releases will make it more stable.
What do I think about the scalability of the solution?
Right now, there are some limitations. However, what I am hearing is that future technologies will be more scalable than what we have now.
How are customer service and technical support?
They have pretty good technical support. They have a different support model for the hypervisor customers, so I have been quite happy with the support until now.
Which solution did I use previously and why did I switch?
The previous solutions that we have are both IP and Fibre Channel-based. We are moving away from Fibre Channel, so we wanted to look for a new solution which was IP-based.
How was the initial setup?
The initial setup and deployment were straightforward.
What was our ROI?
We have seen ROI.
Which other solutions did I evaluate?
We looked at multiple vendors.
