Snapshot, because so much of it is on our end-user storage, our users often delete things they’re not supposed to. Having snapshots to revert these deletes quickly and easily is very valuable.
Enterprise Data Storage Engineer III at University of Kentucky
Snapshots lets us revert accidental deletes quickly and easily, and although we had an outage when batteries were bad, it was a known defect and our fault for knowing this was an issue.
What is most valuable?
How has it helped my organization?
Our greatest advantage with it is ease of use, flexibility, and reliability.
What needs improvement?
Knowing what’s coming down the pipe, NetApp is headed in the right direction. In their five year roadmap, it provides what I need it to do.
What do I think about the stability of the solution?
It's extraordinarily stable. We had one outage one-and-a-half years ago when batteries were bad, but that was a known defect on that particular model. However, that was our fault for knowing this was an issue. We've had two outages in 10 years due to something other than operator’s error.

839,422 professionals have used our research since 2012.
What do I think about the scalability of the solution?
Incredibly scalable. Not even touching what it could do. Between scale up and scale out, we’re not even close to reaching its highest potential. We have a four node NAS with the potential for 24 nodes.
How are customer service and support?
It's fantastic.
How was the initial setup?
Once you’ve done one, it seems very intuitive. However, the first time seems very complicated.
What other advice do I have?
Of all storage technologies I work on, it’s the easiest to learn and one of the most powerful. But you need to spend your time taking classes before digging in too deep. Get educated.
Disclosure: I am a real user, and this review is based on my own experience and opinions.
Storage Engineer III at Providence Health & Services
We use the NAS functions for all our file shares, although I wish we could do dedupe for the entire system and not just a specific volume.
Valuable Features
NAS functions, as it's primarily used for all our file shares. We have other NAS devices, but this is easier.
Also, High Availability is a valuable feature.
Improvements to My Organization
Snapshots are good, especially the snap mirror, which we use for disaster recovery and backups. Also, we have a lot of data centers (seven primary centers) and we deploy at each of them.
Room for Improvement
I miss their old support structure. We used to be able to call up and get an answer pretty quickly, but now it’s more arduous.
It could be cleaner for dedupe, and I wish we could do dedupe for the entire system and not just a specific volume.
Stability Issues
It's highly reliable, but has had the occasional bug. We install patches or shut off features.
Scalability Issues
Depends on how you’re scaling. If wide, it works well. Vertical scaling not so well because we’re primarily SMB. No matter how brief, people don’t like being offline (e.g. baby monitors).
Customer Service and Technical Support
I’ve worked with them for over 10 years. They used to be stellar, but in the last three to five years, not as reliable. The quality of information you get from them is less specialist, and they've not broken it up so that you get routed to a particular technology, it used to be one senior guy who knew everything.
Initial Setup
There’s always networking issues, but not related to NetApp.
Other Advice
Other than tech support, it loses points because it could always be better.
It depends on what you’re implementing. Consider carefully what you want to do – for example, have enough vLANs because you don’t want to be adding more later.

IT Architect at a aerospace/defense firm with 1,001-5,000 employees
We can give people large amounts of storage for projects, and then remove it, though improvements could be made to the translation between 7-mode and cDOT.
Valuable Features
We have clusters, and can do non-distruptive upgrades with cDOT and can spin up VMs as needed. We have the flexibility to give people NAS storage.
Improvements to My Organization
With NAS storage in general, we can give people large amounts of storage for projects, and then remove it. For example, for SLS, they can spin up large amounts of storage to hold the output of modeling data, and when that’s done, they can delete it and move on. In that case, they don’t need the throughput.
We have thousands and thousands of file shares and we’re able to offer up to one terabyte of storage, and this gives us high compression and dedupe.
Room for Improvement
For cDOT in general, improvements could be made to the little things, such as the translation between 7-mode and cDOT. If there’s some kind of backward compatibility or translation of certain functions from one to the other, that would be an improvement.
Stability Issues
It's very stable.
Scalability Issues
With cDOT, it's very good. It scales horizontally well, but not so well with 7-mode.
Customer Service and Technical Support
It’s top-notch support, very responsive and highly knowledgeable, very attentive to us as we have a monthly meeting with our TAM.
Initial Setup
It's straightforward in 7-mode, but using cDOT, it's terrible.
Disclosure: I am a real user, and this review is based on my own experience and opinions.
There is a transition tool that will move the data from 7-mode to CDOT. However, SnapVault relationships cannot be retained when moving from 7-mode to CDOT. This means that multiple copies of the data must be retained until SLA expiration policies allow for it to be deleted (in my case, years). I was speaking specifically about the translation of commands used to admin the system. Commands you knew by heart in 7-mode no longer work in CDOT. There are many things to like about CDOT, which is why we are making the move, but there are many things that don't work as well as they did in 7-mode. For instance, there is no ability to disable NETBIOS over TCP in CDOT and active directory integration is much harder to setup and manage.

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.

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
Disclosure: My company has a business relationship with this vendor other than being a customer: We're a partner.

Scalable and reliable, but support could improve
Pros and Cons
- "The solution is stable."
- "We're supposed to have used NetApp FAS Series for replication, but then one of the nodes failed, and then it's taken us some time to bring it up."
What is our primary use case?
I am using NetApp FAS Series for file backups.
What needs improvement?
We're supposed to have used NetApp FAS Series for replication, but then one of the nodes failed, and then it's taken us some time to bring it up.
The management console and disc partitioning could improve.
For how long have I used the solution?
I have used NetApp FAS Series within the past 12 months.
What do I think about the stability of the solution?
The solution is stable.
I would rate the stability of the NetApp FAS Series an eight out of ten.
What do I think about the scalability of the solution?
The solution is scalable. We have not done much scaling but we know it can.
How are customer service and support?
The support for NetApp FAS Series has not been great.
How was the initial setup?
The whole installation wasn't done right from the start. I think that's where the problem started.
What's my experience with pricing, setup cost, and licensing?
We are on a perpetual license.
What other advice do I have?
I would recommend
I rate NetApp FAS Series a seven out of ten.
Which deployment model are you using for this solution?
On-premises

You can run a smaller aggregate with SSDs in the flash pool.
What is most valuable?
It takes your standard IOPS in your drives and it gives you much greater performance out of that aggregate. You can run a smaller aggregate with SSDs in the flash pool, and it'll give you the IOPS of many more spindles. What it does is it brings your SATA disks aggregate up to the SAS speed, depending upon how many spindles you're running, and your SAS aggregates perform much better.
How has it helped my organization?
We had an IOPS problem earlier. We were running Citrix and we were having boot storms. Part of the problem was the aggregates that we had were too small. The boot storm would basically fill up the NVRAM. It was unable to write to disk because the disks were running full. The problem was solved by going to flash pools. It was great.
What needs improvement?
I have not given the FAS a perfect rating because the All Flash Array is probably going to beat it down, in terms of performance.
I would give it a perfect rating if there wasn’t any ceiling. When you have some systems and you increase your disk IOPS by adding either All Flash Array or you add a flash pool, sometimes you move the bottleneck; you move the bottleneck up to the CPU. We did have that problem briefly. That was solved by basically moving some of the workload. That happened one time and we fixed it.
By moving to cluster mode, it's going to be a lot easier to move the workload. We are moving in that direction. We're doing the first assessment and planning right now.
What do I think about the stability of the solution?
We do not have any stability problems, whatsoever.
What do I think about the scalability of the solution?
NetApp aggregates are scalable. You can keep adding shelves.
How are customer service and technical support?
Technical support is very good. I've never had a problem.
Usually the problem is being able to hear them in our data center. :)
Which solution did I use previously and why did I switch?
I did not previously use a different solution. When I started working with the county, they already had the NetApp FAS.
What other advice do I have?
Go with NetApp; I haven't had a problem with it.
The most important criteria for me when selecting a vendor to work with are reliability and, for technical support, being there.

It behaves predictably during failure, but it needs better built-in monitoring as Insight is too expensive.
Valuable Features
It’s a decently mature product that has a lot of documentation and standards and is something to be relied on.
Improvements to My Organization
Predictable behavior during failure. In terms of performance, if you have two machines, you know they’re going to perform the same.
Room for Improvement
It needs better built-in monitoring. We can’t afford Insight, and v6.2 seems like it's a purposefully inferior product to make people buy Insight, which is way too expensive.
Stability Issues
It's not on Cisco’s stability level, but it’s a 96/100.
Scalability Issues
It’s scalable, but it could be easier. Just adding shelves might require additional cards and cabling, which can be difficult.
Customer Service and Technical Support
I’m happy with the support, as they’ve been able to solve whatever I throw at them.
Initial Setup
It’s complex as there’s a lot of variables involved. Not for the weak-hearted, if you haven’t done it before.
Other Advice
It loses points because of failures.
