842,388 professionals have used our research since 2012.
What do I think about the stability of the solution?
It is generally very stable.
How are customer service and support?
Technical support has gone down in my perspective. When getting to the root cause of issues, they need to respond faster. Also, they need to respond quicker to bug fixes.
There have been some changes internally at NetApp. Currently, we are moving to a different level of support which will hopefully fix our issues with it.
Which solution did I use previously and why did I switch?
We use NetApp products. If we switch products, it is because the product does not perform or is not keeping up with its competitors in terms of cost.
What about the implementation team?
We did the deployment ourselves. Deployments are easy, but NetApp could make it easier.
What was our ROI?
Return on investment has been good.
What's my experience with pricing, setup cost, and licensing?
There are specific workloads where some vendors provide better value, but in general, NetApp has done a far better on price than other vendors.
Which other solutions did I evaluate?
We have used Hitachi and Dell EMC, but we use NetApp the most.
What other advice do I have?
It is a good, market-leading product.

System Administrator at a tech vendor with 501-1,000 employees
Technical support is good. Their solution engineers are good at architecting designs which are standard, but also future thinking.
Pros and Cons
- "SnapMirror is a good solution, because we can take our production data and replicate it over to our DR data center with minimal administrative effort, which is huge."
- "Technical support is good. NetApp's solution engineers are good at architecting designs which are standard, but also future thinking. I've only opened a few tickets, and they've answered my questions each time. NetApp takes less than four hours to respond."
- "I would like to see FlexGroup volumes come to parity in terms of software features with Flex volumes. It seems like FlexGroup volumes have massive scalability, but their features set is not the same as Flex volumes, so we are currently unable to use it."
What is our primary use case?
Our primary use case is file storage. We use it for SMB CIFs and Fibre Channel LUN for Hyper-V.
How has it helped my organization?
Our administrative effort is lower.
DR is much easier now. It is essentially just flipping a few switches, then we have replicated data up in our DR data center. We have done the tests, and it works perfectly. We also have file services which are DR, where we flip another switch and all our files are in another easy place to locate.
What is most valuable?
SnapMirror is a good solution, because we can take our production data and replicate it over to our DR data center with minimal administrative effort, which is huge.
What needs improvement?
I would like to see FlexGroup volumes come to parity in terms of software features with Flex volumes. It seems like FlexGroup volumes have massive scalability, but their features set is not the same as Flex volumes, so we are currently unable to use it.
What do I think about the stability of the solution?
The stability is perfect. Even when we are doing upgrades to the ONTAP cluster, such as rolling upgrades where one node will take over the other cluster's volumes, we have zero downtime.
What do I think about the scalability of the solution?
Scalability is great. We are in current discussions to obtain another two nodes to our ONTAP cluster. So, two more nodes to our already two node cluster, and we don't expect any downtime. We have seen how much it can scale in terms of numbers, so we are happy with it.
How is customer service and technical support?
Technical support is good. NetApp's solution engineers are good at architecting designs which are standard, but also future thinking. I've only opened a few tickets, and they've answered my questions each time. NetApp takes less than four hours to respond.
We once opened a ticket to have a technical support person online at two in the morning for a cluster upgrade. The technical lead was online and supportive, and nothing went wrong with the upgrade.
They have awesome technical guides and documentation.
How was the initial setup?
The initial setup is straightforward, because getting a storage system installed is not the hardest thing. It takes some know how, but it's not an impossible task.
When we do a controller upgrade from a FAS8200 to a FAS9000, I want somebody there to watch over the upgrade because something can go wrong, and I do want technical help. However, the cool thing is while we're apprehensive and know what can happen, it never has. We're too cautious.
What about the implementation team?
Meridian and ePlus implemented our solution. We had no issues and found them to be knowledgeable.
Which other solutions did I evaluate?
We look at the other companies, like Dell EMC and Nutanix. We decided to go with NetApp because they are an industry leader. We also liked their SnapMirror and SnapVault features.
What other advice do I have?
ONTAP is easy and works. It most likely has all the features you need, and then some.
Each ONTAP upgrade has brought us new features, like rest encryption.
The new solution is crazy small and compact.

Storage Engineer at Evolent Health
Clustered ONTAP makes it very easy for one person to manage petabytes of data
Pros and Cons
- "Clustered ONTAP makes it very easy to manage large amounts of data, measured in petabytes. One person can manage all that."
- "We bought it for a couple reasons. One, it took advantage of our existing storage because we could front-end that storage. It also allowed us, through native replication, to set up a DR site, which we're working towards. And three, that DR site, in 2020, is going to the cloud. NetApp has a nice solution for that. And our production in 2022 may actually go to the cloud. So all that is already in place, no additional tools. You can use the same SnapMirror and SnapVault technology to get there."
- "I would like to see volume efficiency come closer to what Dell EMC can do with, for instance, their XtremIO platform."
What is our primary use case?
We use it for VMware.
How has it helped my organization?
Clustered ONTAP makes it very easy to manage large amounts of data, measured in petabytes. One person can manage all that. In the old days, you could never do that.
What is most valuable?
We're using it as a virtualization platform, so not only are we buying NetApp SSD, we're also able to utilize our existing Dell EMC storage that still is under support.
What needs improvement?
I would like to see volume efficiency come closer to what Dell EMC can do with, for instance, their XtremIO platform.
For how long have I used the solution?
Less than one year.
What do I think about the stability of the solution?
Today, the stability is very good.
What do I think about the scalability of the solution?
The scalability is very good.
How are customer service and technical support?
The technical support is poor. The first line people that pick up the phone are, quite honestly, awful. Once you get to an escalation engineer they're extremely talented, but you have to pull teeth to get there.
Which solution did I use previously and why did I switch?
My management was all about Dell EMC. With my experience with NetApp I just kept my mouth shut and asked technical questions and Dell EMC basically fell flat. They actually proposed a mid-tier solution that was, as they put it, a number of storage silos. And I said, "This is 2018. We have storage silos?"
So I was able to work with CDW and prove that the FlexArray would front-end the existing Unity's and 3PARs we have. CDW ended up coming to the table and they won the deal. They came in late but they won the deal. The NetApp people have never come to our office yet.
How was the initial setup?
We did purchase Basic Install, so it was straightforward.
Which other solutions did I evaluate?
Dell EMC and Pure were on our shortlist. Dell EMC couldn't come with a reasonable solution. Pure is all-flash and we needed hybrid.
What other advice do I have?
I would advise colleagues who are researching this type of solution to look at NetApp. We bought it for a couple reasons. One, it took advantage of our existing storage because we could front-end that storage. It also allowed us, through native replication, to set up a DR site, which we're working towards. And three, that DR site, in 2020, is going to the cloud. NetApp has a nice solution for that. And our production in 2022 may actually go to the cloud. So all that is already in place, no additional tools. You can use the same SnapMirror and SnapVault technology to get there. To me, it makes sense.
We bought our solution through CDW. They're excellent.
I would rate this solution at eight out of ten. I think it's time for a hardware refresh. We ended up buying 8200s and they've been out on the market for quite a while. There is newer hardware that we were hoping to take advantage of but we needed the storage now.

Admin at Centene
ONTAP OS is super easy to use; failover works well
What is most valuable?
Definitely ONTAP. The command line. It's super easy to use.
How has it helped my organization?
The ONTAP is so easy to use. I can do my tasks pretty easily on there. If someone needs something quickly I can give them what they need pretty quickly.
What needs improvement?
The one thing I would really like to see - I don't know if they offer this or not. I know EMC has got really good: their SRDF replication is really good for keeping consistency with your backups, or the other side.
NetApp is crash consistent. I don't know the quality of the EMC one but that one seems to work really well. EMC is primarily block storage anyway so that is what it is build for.
What do I think about the stability of the solution?
It's pretty stable. There have been some random crashes we have had though, from a couple weird things.
There always seems to be some random bug in the code. If there is a random bug in the code, it seems like we have so many of these storage arrays that one of them is going to experience a crash from it. We have had a couple like that, zombie deletes, causing the controller to panic. We have had a couple weird things like that.
What do I think about the scalability of the solution?
Never really implemented one but it seemed to be pretty easy to scale out. If you have the money to buy one, to scale it out is nothing crazy.
How are customer service and technical support?
We have an in-house resource and usually, if there is something going wrong, he is the one that will handle it and give it direction. If we ever call it in we always get the front-line people and typically we don't need the front-line people. When we need support we need someone specialized, like a certain protocol or a certain aspect. Usually, that's kind of annoying, when we call in it's getting front-line people and it is an extra 30 minutes just to get to where we need to go, really.
Which solution did I use previously and why did I switch?
No, ever since I have been here at Centene, we have been using NetApp.
Which other solutions did I evaluate?
I know NetApp and EMC are at the top, but other than that we don't really have any. I haven't seen much for any other vendor, like Nimble or like a couple of others, we don't really deal with those.
What other advice do I have?
We use it for datastores, and do a little bit of SAN on it too. We use it for both, block and file storage.
My impression of NetApp as avendor of high performance SAN storage is that it's not as good as EMC. I don't have any complaints, really. I primarily use NetApp. I only use the EMCs a little bit.
I am more likely to consider NetApp for mission critical storage systems based on my experience with AFF. The failover seems to work pretty well, they seem to be pretty reliable. If you have a lot of clusters, a cluster that's broke out, it works pretty well. If it fails or crashes, you still have to fix it but it still works.
Performance is pretty good. It's a little hard to compare because I'm not really on the OS side. I don't really delegate storage provision so I hardly ever get to see the other side of the systems.
When selecting a vendor the most important criteria include is: can the vendor supply a solution that we need? If we need block storage, can they do block storage very well? If we need good replication, can they provide that? It just depends on what we need it for and if they can provide that solution the best. Our company doesn't have any really money constraint problems. It's more just about the solution than about the cost.
If someone was looking to buy one I would say: I love the ONTAP operating system. The support is pretty good. I would say the block side of NetApp is probably the weak point. It still does it well, but if you are doing file shares and datastores, you could use it for that. That is primarily what we use it for.

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.

Technical Architect at a tech company with 1,001-5,000 employees
The capacity, mid-range performance in the management stack, and its features set are unparalleled
Pros and Cons
- "We use NetApp for its capacity, mid-range performance in the management stack, and its features set are unparalleled."
- "It is not as good as we need from a performance perspective. At the moment, we are always running out of CPU on the controllers, even the high-end solutions."
What is our primary use case?
We use it for electronic design automation, build, and regression.
What is most valuable?
- The management stack
- Performance visibility tools
- Replications
What needs improvement?
The product already has more features than we can keep up with.
I'm looking for a performance bump.
What do I think about the stability of the solution?
It is very stable.
What do I think about the scalability of the solution?
It is good from a capacity perspective, but not as good as we need from a performance perspective, but I'm hopeful going forward. At the moment, we are always running out of CPU on the controllers, even the high-end solutions.
How is customer service and technical support?
The technical support is very good.
How was the initial setup?
cDOT is more complex than 7-Mode, but we're hoping that NetApp makes it simpler as time goes on.
What about the implementation team?
We used a VAR for the deployment. We have a good relationship with them.
Which other solutions did I evaluate?
NetApp has been our workhorse solution for more than 20 years now. It's our main solution that we use. We have been using other vendors for the high performance stuff, but I'd like to see a future where NetApp is an option in this space again.
We use NetApp for its capacity, mid-range performance in the management stack, and its features set are unparalleled. We go to Dell EMC Isilon and Pure Storage FlashBlade for raw performance on things that we can't do on NetApp today.
What other advice do I have?
I would give it an eight out of ten on its feature set, maturity, and global product availability.
Up and coming vendors can provide performance or specific features. However, compared to Hardware Universe, Unified Manager, and replication, along with spectrum, from the FAS2000 that we use out our small sites to FAS9000 that we use for big regressions, these other company don't have the breadth to the feature set that NetApp has today.

Hewlett Packard Enterprise Solution Architect at a tech services company with 11-50 employees
Gives us control of data in the cloud and allows us to pay for what we need
Pros and Cons
- "Vauable features include the ability to manage our data anywhere, multiple consumption modes, and rapid deployment."
What is our primary use case?
We use it to manage data in the cloud.
How has it helped my organization?
It has improved our mobility in managing our data anywhere and anytime.
Also, because it is deployed and managed from NetApp Cloud Manager as a software-only solution on Amazon EC2 compute instances, managing Amazon EBS storage enables customers to build a virtual storage solution directly on Amazon resources.
What is most valuable?
- Total control of data in the cloud
- Multiple consumption modes
- Rapid deployment
In addition, we have some databases hosted in this solution and are very impressed by the performance and speed of the solution.
What needs improvement?
The way you attach, move, migrate, and access LUNs is complicated, and if you do not know how to do it, it can be a great problem for your IT environment.
What do I think about the scalability of the solution?
It can scale according to your IT needs.
What's my experience with pricing, setup cost, and licensing?
There are two consumption methods: pay as you go and subscription. Pay as you go is purchased directly from your AWS account and is charged either on an hourly basis or annually. It is a little expensive but worth it.
Purchasing this solution through AWS Marketplace was secure. We purchased it there because we are AWS customers.
What other advice do I have?
In terms of other products it works with in our environment, we have only tried it with database workloads in AWS.
I rate this solution at ten out of ten because NetApp Cloud Volumes ONTAP provides a level of flexibility that allows you to pay for what you need, when you need it.
