880,745 professionals have used our research since 2012.
What do I think about the scalability of the solution?
With cDOT, it's very easy to scale out, and that's the reason we went with it in the first place.
How are customer service and support?
It's been great, and any issues have been taken care of right away.
How was the initial setup?
It was very straightforward and easy.
What other advice do I have?
Pick your partner wisely, as they have a lot in your success. Go with someone with a history in FAS. Also, go with vendor that buys reference architecture and follows the methodology.

The controllers are faster so we have more processing efficiency, and we're going onto the cDot platform, which is already an improvement.
Valuable Features
Today we use it for replication of our transaction data, and for storing data, for which we use the snap mirror feature. Primary and disaster recovery storage centers are connected. Snap mirror backup software does block level copy from primary site to the disaster recovery.
Room for Improvement
We’re going onto the cDot platform, which is already an improvement. The controllers are faster so we have more processing efficiency.
Use of Solution
We’ve been using it for the last six years.
Stability Issues
Stability has been very good. As far as we’re concerned, we update our systems (firmware, OS) consistently, so we don’t face any problems in that regard.
Scalability Issues
We've had no problems scaling. Our business has grown two and half times in size over six years, and we’ve added more disks and shelves, as well as upgrading controllers. We’ve done it without any down time.
Customer Service and Technical Support
Quite good. Recently we deployed micro-clusters with cDot, the first bank in India to do it.
Initial Setup
It was complex because we experimented by keeping data and system volumes separate. We don’t replicate the system volumes frequently. We were able to do it, although we used only 1/10 of the bandwidth with a combination of FAS and vSphere.
Other Advice
Configure it properly. Today we have HA with any data loss because we did it nicely, and took our time for the beginning. We got terrific support.

Senior IT Tech-Architect, Storage at a healthcare company with 1,001-5,000 employees
It's added benefits are thin provisioning, compressioning, and dedupe, which help with capacity utilization.
Valuable Features
Being able to run any flavor of files and block storage. It's easier to manage, and we’re looking to phase out legacy systems and to go with FAS.
Improvements to My Organization
It's easy to manage regardless of how you’re utilizing platform. It’s a Swiss army knife of capabilities. Flexible platform and software features are added benefits (thin provisioning, compressioning, dedupe), which help with capacity utilization. Still get a lot of return even if going with best-practices application.
Room for Improvement
Make sure there’s current centralized virtual desktops. I get caught in the upgrade matrix quite a bit, which is an indication that it hasn’t been tested. Need more currency in IMT.
Stability Issues
It's solid, with occasional issues that surface, but are quickly resolved. No one’s software is perfect.
Scalability Issues
It’s good, but you have to do a lot of homework to scale horizontally and vertically. You need to have sales and engineering to expend effort to do that homework.
Customer Service and Technical Support
We've frequently used it, and the quality will depend on which level of support you purchased. Premium support, I have no complaints as we get the right person who’s knoweldgable. Higher level guys take great deal of personal ownership over issues. I used their support as benchmark for our organization.
Initial Setup
It's easy. The more planning you do, the easier it gets.
Other Advice
The monitoring is key, and you must keep track of what’s going on. Be sure to use auto-support and have strong monitoring scenario in place.

Senior Systems Administor at a tech vendor with 501-1,000 employees
We are able to increase performance by adding more heads to a cluster, but the free performance monitor doesn’t provide enough information.
Valuable Features
Management, for a person who’s not a storage administrator In a couple of weeks, you can get the basics of createing virtual storage, and carving out chairs and LUNS.
Improvements to My Organization
Doing more with less. I can do multiple protocols, storage efficiency, data protection tool, everything is in one solution/ecosystems. There aren't many vendors who can provide that without adding third party software and apps.
Room for Improvement
Our major issue with FAS was not having one pane of glass with all products attached to it. Other major issue is the free performance monitor doesn’t provide enough information. They want you to buy Insight, which is very expensive.
Stability Issues
It's rock solid.
Scalability Issues
I love cluster ONTAP. Being able to scale out and being able to increase performance by adding more heads to a cluster and being able to do hybrid with regular storage on same platform is huge. You can move out easily too, they provide you the tools to do that, adding a lot of value.
Customer Service and Technical Support
Great, I cannot complain. They’re there with you until problem resolved.
Initial Setup
It's straightforward setup. Depending on how you deploy, full SAN is complex, with NAS not so complex. You have to follow best practices when building out infrastructure. So, it’s not so different than deploying it with other vendors.
Other Advice
With storage, what works for me won’t necessarily work for you. Call your NetApp rep and tell him you want to test the solution. Get it on the floor and beat the hell out of it. Do a very thorough Proof of Concept.

Chief Technology Officer at a healthcare company with 51-200 employees
It's highly scalable, especially with CDOT, but they should make it faster and cheaper.
Valuable Features
- Snapshot
- Snapmirror
- FlexClone
Improvements to My Organization
- Huge time savings
- Large storage space savings
- In the end—time and money
Room for Improvement
They should make it faster and cheaper, but it does what we need it to do.
Stability Issues
Good overall. We’ve hit some bugs in the ONTAP code that’s caused it to crash. We’re just coming off of seven-mode, and I'm looking forward to the capabilities of CDOT.
Scalability Issues
It's highly scalable, especially with CDOT. We can scale out quickly.
Customer Service and Technical Support
It's very good, generally first tier are wiling to help us or get us to right person pretty quickly.
Initial Setup
It was complicated. We were coming off an IBM system five years ago. We got help for everything from cabling, terminology, and we had to relearn how we reconfigured storage. We got help from both NetApp and our VAR.
Other Advice
Just do it. Chances are the functionality that comes with the ONTAP software will be better than other products at a similar price.

VP Systems Integrator at a financial services firm with 10,001+ employees
We can add additional heads with the same IOPS, but we need better documentation for customers to understand automation of APIs.
Valuable Features
The flexibility to use in OpenStack with multiple data types, Cinder, Swift, etc.
Improvements to My Organization
Feasibility to use multiple protocols to talk to device, be it direct attached or Cinder/Swift, and the ability to use it as storage behind guest instances on cloud (commonly known as boot-from-disk).
Room for Improvement
When speaking with the NetApp CEO, we told him that we need better documentation for customers to understand automation of APIs. We want it all there and robust. Boot-from-disk allows me to use disk from Netapp, and understand how to set that up should be documented so I can teach my staff how to do that.
Use of Solution
We've been using NetApp products for 15 years.
Stability Issues
No issues encountered.
Scalability Issues
As we continue forward, we can add additional heads with same IOPS.
Customer Service and Technical Support
I've never had to call tech support, but we’ve had them call us to tell us we were about to have a problem.
Initial Setup
It was very straightforward with OpenStack, very well-documented, and supported. I wasn’t an OpenStack admin when I started, so the ease of use was critical to me. Straight from the horizon dashboard from OpenStack and I was up and running in 15 minutes
Other Advice
- Define use cases because we’ve come across where we didn’t do so correctly, and we had to go back and re-architect everything. This was our failure.
- Really engage with NetApp to understand how you use the nuances of things like the APIs.

Principal Computer Engineer with 1,001-5,000 employees
Since implementation, our performance has definitely increased, but they're upgrading the performance monitoring tool, which is the main thing I think needs improvement.
Valuable Features
I think that the flexibility with the volume, resizing, and performance.
Improvements to My Organization
I think that our performance has definitely increased.
Room for Improvement
I think that they are upgrading the performance monitoring tool, which is the main thing I think needs improvement. From version to version they are changing, and you want to see things improve – I think we will continue to see more and more benefits.
Use of Solution
We have been using it since 2013.
Stability Issues
Pretty solid in terms of stability.
Scalability Issues
We haven’t really grown it but I see a roadmap, the only problem there may be cost. It’s not an expensive product per se, but because of budget issues. People sometimes don’t evaluate the cost correctly.
Customer Service and Technical Support
NetApp overall has been really good in terms of technical support.
Initial Setup
Initial setup was hard a year ago, but now we just did another setup and everything was smooth. It’s gotten a lot better in the last year we’ve been using it.
Other Advice
If you are on the fence it’s been a very good product, you don’t want to build your own solution, you want to use the appliance for the flexibility. Overall performance has gotten a lot better.

System Engineer at a tech services company with 51-200 employees
It comes with an OS developed by its engineers, and its clustered data ONTAP, which supports clustering and high-level scalability.
What is most valuable?
- Deduplication
- High Availability
How has it helped my organization?
It provides us with a very effective storage solution.
What needs improvement?
The virtualization technology.
For how long have I used the solution?
I've used it for over three years.
What was my experience with deployment of the solution?
Absolutely, it’s just some compatibility variance with some of the production environment aspects, like AV, and Archiving systems which needed to be integrated with.
What do I think about the stability of the solution?
Not at all as the HA features are great.
What do I think about the scalability of the solution?
NetApp comes with an OS developed by its engineers, and its clustered data ONTAP, which supports clustering and scalability to a high level.
How are customer service and technical support?
Customer Service:
The support team supports us as vendor partner with a lot of tools. And the auto-support feature is just as amazing as the product, whenever a disk fails or any issue occurred the features sends alerts to you and to the customer, and send you a replacement of the disk right away, in a very effective manner, and quickly, that you may do not notice that there’s an issue in your that disk.
Technical Support:10/10.
Which solution did I use previously and why did I switch?
I deal with a lot of solutions similar in the concept with NetApp FAS, but when it comes to NetApp, there are too many features that means it worth it.
How was the initial setup?
It was clear and straightforward, as you console the device, and it boots, you configure and initialize the product, and as soon as that is done, you are ready to create your aggregates, volumes, and shares.
What about the implementation team?
We are an integrator, and we also have an in house device that we run our test labs on.
The NetApp technical team is very supportive, and they can, in some complex and large projects, come and share the in-site implementation with their partner.
What was our ROI?
We can't calculate this.
What's my experience with pricing, setup cost, and licensing?
Prices may seem to be a little bit expensive, but the features just makes you happy that you took the step, and licensing is all included except a very few features, with a high end and complex environment.
Which other solutions did I evaluate?
EMC
