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 a university with 1,001-5,000 employees
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.

NetApp FAS Series
January 2026
Learn what your peers think about NetApp FAS Series. Get advice and tips from experienced pros sharing their opinions. Updated: January 2026.
880,745 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.

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.

Senior Storage Engineer with 1,001-5,000 employees
It provides us with a single unified-type architecture for block-and-file-type data storage. But, if I'm running dedupe, fiber channel, and other protocols on the same CPU core, I can’t load-balance.
Valuable Features
- Dedupe
- Also, our customers look for fast connectivity and cost efficiency.
- It's TCP/IP vs. fiber channel, which tends to be more costly.
Improvements to My Organization
- Single unified-type architecture for block-and-file-type data storage
- Ease of use
- Being able to hand off things like snap shots directly to customers
Room for Improvement
They need to improve the go-to-market for all-flash and converged infrastructure. What is your goal-to-market vision, and when to get there? They’re too slow compared to others and what they’ve done in the past. They were the leader in dedupe, but now, it’s not such an innovative edge.
It lacks flexibility in failover and failback, so we cannot granularly failover pieces. It's not easy to move one piece over to the other side.
Also, from the overall workload standpoint, all protocols are handled in just one physical architecture. So if I'm running dedupe, fiber channel, and other protocols on the same CPU core, I can’t load-balance. I’ve seen issues specifically with EMP, one core is maxed out, and I can’t use the other cores to handle it.
Stability Issues
Fairly solid 5-9 array. FAS is a solid architecture in 90% of the environments.
Scalability Issues
Scalability especially in SMB range has been well-received. So long as the environment is sized correctly, it’s been good.
Customer Service and Technical Support
I have had both good and bad experiences, depending on what tier I get to initially. Now it’s tiered, whereas it used to be one senior guy.
Other Advice
If historically you’re a NetApp customer, it’s not as complex as cluster mode. It requires a lot more complexity – command line is not so friendly for storage admins. I’d recommend also sticking with what you know.

Sr. Systems Administrator at a university with 1,001-5,000 employees
Snap mirror gives us a way to snap to our two DR sites to instantaneously bring up VMs, but it lacks certain how-to guides.
Valuable Features
- Snap mirror as it gives us a way to snap to our two disaster recovery sites to instantaneously bring up VMs
- Dedupe helps us to save a lot on OS files for VMs
Improvements to My Organization
It provides a relatively cost-effective solution, as we have all our virtual infrastructure on NetApp.
Room for Improvement
They should provide more specific how-to guides. For example, I want to implement Sharepoint, but how do I do that?
Deployment Issues
Upgrades are always hold-our-breath situations. I’ve been lucky, but I’ve heard horror stories. I’m also dead-ended.
Stability Issues
It’s been good. We haven’t had a complete outage (other than when our network the went down). We’ve had some challenges with hardware, but this was done non-disruptively with failover.
Scalability Issues
We’re still on 7-mode, but it still scales fairly well as the 6240 is a hefty machine.
Customer Service and Technical Support
It's used for repairs. We got outside help with set up and to put processes in place. Once done, it was seamless.
Initial Setup
Very straightforward. We’re using 7-mode, so nothing fancy, and I had no difficulties. There were a couple things I didn’t know, but our partner, DataLink, helped. Specifically, I didn’t understand the rate groups and when you expand aggregates, you have to do a full regroup, which wasted a lot of space. I had 16-disk rate groups, added five disks, and it unbalanced things.
Other Advice
Six to eight months ago, I would have said go for it, but now I’ve been getting a lot of doubts about the stability of NetApp itself as a company.
Disclosure: My company does not have a business relationship with this vendor other than being a customer.
Re: Setting up Sharepoint. Contact any NetApp sales engineer, they can point you to one of two things, either KB documentation or NetApp has a 'helpline' that you can call and ask for information on How-To's such as this. I agree though, they do not make guides easy to come by, but they do exist.

The snap products allow the end-user to make restorations and perform offsite replications.
Valuable Features
- Redundancy
- Snap technologies (snap mirror, snap shots)
Improvements to My Organization
The snap products allow the end-user to make restorations and perform offsite replications. Also, it gives us secure multi-tenancy.
Room for Improvement
Nothing that I can think of right now.
Use of Solution
We've used it for seven in years.
Stability Issues
It's pretty stable. We've only needed NetApp engineers to help with an issue once since we started using it.
Scalability Issues
Very scalable, haven’t reached its limits.
Customer Service and Technical Support
Generally goes well.
Initial Setup
Very straightforward from rack stack to configuration.
Other Advice
With FAS and other NetApp tools, they make for a very intuitive solution. It's simple to manage, very scalable, one-stop shop and many native things that make it very powerful.

Is this OEM from CommVault?
Senior Storage Engineer with 1,001-5,000 employees
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.
Disclosure: My company does not have a business relationship with this vendor other than being a customer.
System Engineer at a legal firm with 501-1,000 employees
It gives us continuous uptime and we can failover when needed, although sometimes there are bugs with firmware upgrades.
Valuable Features
- Uptime
- Performance
- High Availability
- Disaster Recovery
- NetApp as a company is doing well
Improvements to My Organization
- We can failover when needed.
- In my organization, a law firm, brand recognition is important, and NetApp provides that.
- It gives us continuous uptime.
Room for Improvement
Sometimes there are bugs with firmware upgrades.
Deployment Issues
Not with deployment, but, again, there are sometimes bugs when we perform upgrades.
Stability Issues
It just works, and when some drives go into failure status, it’s just a prediction of drive failure, letting us know when to get the drives replaced.
Scalability Issues
It scales pretty well, and the limit is how much you want to spend on blades, shelves, controllers, etc.
Customer Service and Technical Support
It's pretty good, they're very knowledgable. With other vendors who outsource support, there's difficulty getting knowledgable first-tier support, but with NetApp, that’s different.
Initial Setup
We had help in the installation, which made it straightforward. It was also complex because lots of planning was involved.
Other Advice
It loses points in upgrades from one version to another is not as smooth as it should be. Also, understand your requirements and see how it fits in.

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: My company does not have a business relationship with this vendor other than being a customer.
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.
