Resilient storage but latency and IOPS could be better
Pros and Cons
- "I would like to see less latency and higher IOPS."
What is our primary use case?
We use it for storage and it has performed fine, but now we need to upgrade.
What is most valuable?
We like its resilience. It's reliable storage.
What needs improvement?
I would like to see less latency and higher IOPS.
For how long have I used the solution?
More than five years.
What do I think about the stability of the solution?
Stability is very good.
What do I think about the scalability of the solution?
I'm satisfied with the scalability.
Which solution did I use previously and why did I switch?
We did our research and, at the time, NetApp was what we chose. Our most important criterion when selecting a vendor is reliability. The price is, obviously, always an issue but reliability and the quality of the product are most important.
How was the initial setup?
The initial setup was very, very straightforward.
What other advice do I have?
If you need reliability, definitely go for NetApp.
I rate it at seven out of 10 because it has been very reliable but not very good when it comes to IOPS and latency.

Double-parity RAID guarantees that our data stays intact
Pros and Cons
- "One of the most valuable features offered is double-parity RAID, which guarantees that your data will stay intact. We're also able to provision storage and monitor which ones are really consuming storage."
- "It lacks automatic tiering, When you use data, some of it goes cold. It is not hot data, so the system should automatically move that data to the SATA, while the hot data is kept on tier-one, the SaaS or SSD drives."
What is our primary use case?
The primary use case is for regular databases and file systems. So far it has been good. The performance is solid, it's robust, availability is solid.
How has it helped my organization?
We're able to keep data for a longer time because we are able to manage it well using the features that NetApp provides. It has also helped us to quickly deploy our test environment and finish all of our testing before we deploy on the customer side or the customer systems. It has really helped in our operations and our productivity.
What is most valuable?
One of the most valuable features offered is double-parity RAID, which guarantees that your data will stay intact. You can experience two disk failures and still be up. Another feature is the deduplication. It saves a lot of space. We're also able to provision storage and monitor which ones are really consuming storage.
What needs improvement?
I want to see the system automatically tier; we call it auto-tiering. When you use data, some of it goes cold. It is not hot data, so the system should automatically move that data to the SATA, while the hot data is kept on tier-one, the SaaS or SSD drives.
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 solid. You can go over 3,000 days without a reboot or any downtime. It's so stable.
What do I think about the scalability of the solution?
The scalability is also good. You can scale on the fly, just connect the cables. If you're adding a controller or you're adding big shelves, it's easy to move. It's excellent.
How are customer service and technical support?
I'll give technical support a "good" rating because sometimes it's slow in getting people to respond, other times it's okay.
Which solution did I use previously and why did I switch?
When I arrived at the company they were using NetApp, and we are still using NetApp.
When selecting a vendor, I first look at how robust the solution is that they're proposing, and how available they are to answer calls if there are any issues. This is very critical. The robustness of the solution and the availability of the vendor to attend to queries are important components of my selection criteria. After-sales support is also very key.
How was the initial setup?
The initial configuration is very straightforward. You just cable up your system, power up, connect your power cables, connect to the console, boot up the system, do your system configuration, IP configuration, and all the other configurations, and the system is up and good to run.
What other advice do I have?
If I were to advise someone researching NetApp FAS Storage or a similar solution, I would want to understand what they really want. I would advise them to go with NetApp because it's unified storage. It supports both NAS and SAN environments, so whether you're doing block storage or you're doing file storage, it is a good solution. Also, the operating system that it runs is called Data ONTAP, and is cloud-ready, so in the future the file storage that you have can be deployed to the cloud.
I rate this solution a 9.9 out of 10 because it's never failed me so I'm very comfortable with it.

Senior Network Administrator at a financial services firm with 1,001-5,000 employees
The scalability is good, but it's too expensive
Pros and Cons
- "It is good to have a unified storage where you can have block and file level protocols."
- "The only downside is in ease in management; it is not easy to use."
- "It's not a cheap system. It is very expensive. The pricing has been ridiculous every time that we had to renew the support."
What is our primary use case?
The product has been pretty stable. Though we have had a few issues, not on the ones that we are going to replace, but on a couple of other ones. On the ones that we are going to replace, we usually use them for file storage and Exchange. The others are mainly used for interface and iSCSI.
How has it helped my organization?
It has been a pretty stable environment, but over time our requirements have changed. Therefore, I don't think it's an issue with the system. We have put a lot of load on a lot more than what it can handle. So, it has taken a performance hit. I wouldn't put it down to there being an issue with NetApp. It's simply because it has more load on it than it can handle, so it has taken a performance hit.
The only downside is in ease in management; it is not easy to use.
What is most valuable?
It is good to have a unified storage where you can have block and file level protocols. It has been pretty stable, but the capacity requirements have changed overtime. Our utilization has been very high, so the performance has taken a hit, which is why we are replacing it.
What needs improvement?
- Ease of management needs to be improved.
- The power consumption for the FAS is a lot more compared to the new SSD arrays.
Going forward, I don't want to be using the FAS again. I want to be using AFFs more.
For how long have I used the solution?
Three to five years.
What do I think about the stability of the solution?
It has been pretty stable. It has been pretty good, and when we have issues, the support has been great as well.
I am pretty happy with the system, and the performance issues that we are experiencing have nothing to do with the NetApp system. It's simply because it has more load than it can handle.
What do I think about the scalability of the solution?
The scalability is pretty good, but it's too expensive.
How are customer service and technical support?
Technical support is cooperative and good.
Which solution did I use previously and why did I switch?
We were previously using an old IBM SAN. We switched because we wanted to moved to a unified system.
How was the initial setup?
We had a reseller set it up for us, simply because it was a little too complicated.
What's my experience with pricing, setup cost, and licensing?
It's not a cheap system. It is very expensive. The pricing has been ridiculous every time that we had to renew the support. Initially, we have a three-year support contract when we bought the system, but the subsequent renewal of maintenance was ridiculous. This is why we have not been too keen on NetApp.
What other advice do I have?
I wouldn't recommend NetApp FAS. I don't understand why anyone would go for NetApp FAS when you can get the NetApp AFF, which is an SSD array, for almost a similar price or probably even cheaper.
Most important criteria when selecting a vendor:
- Cost effective solution
- Performance
- Reliability
- A good roadmap.

It is stable and integrates well with other components
Pros and Cons
- "The initial setup was so straightforward. It was well-documented."
- "It is very flexible. It integrates well with the public cloud and other components, so everything can be API driven. Therefore, it is very easy to automate it."
- "We would like to have further integration with some backup products. They have some of them already, but there could be more."
What is our primary use case?
We use NetApp as our primary storage. Because we are a system integrator, we managed more than 100 data petabytes of data of our customers.
How has it helped my organization?
It is very flexible. It integrates well with the public cloud and other components, so everything can be API driven. Therefore, it is very easy to automate it.
What is most valuable?
It is very stable and integrates very well with other components.
What needs improvement?
We would like to have further integration with some backup products. They have some of them already, but there could be more.
We have already seen the new roadmap and a lot of our requested features are already on it.
What do I think about the stability of the solution?
It is very stable. We use it for more than 100 petabytes. We do not have any issues. We have never lost data.
What do I think about the scalability of the solution?
It acts as it was documented.
How are customer service and technical support?
I do not speak with the NetApp support.
Which solution did I use previously and why did I switch?
We have always used NetApp, so we did not switch from another vendor.
How was the initial setup?
The initial setup was so straightforward. It was well-documented.
Which other solutions did I evaluate?
We have almost all vendors in our portfolio: EMC, Pure Storage, etc.
As our stand up, we use NetApp because we are pleased with it. Other vendors have good ideas, but they are not yet implemented in NetApp, hopefully that will come one day.
What other advice do I have?
Use NetApp, it is good. There are more specialized products in the market, but NetApp is a very good general fit.
We have a lot of product knowledge, and it is not 100 percentage perfect. However, we know where it behaves well, and where does not.
Most important criteria when selecting a vendor: We always check the vendor to make sure our clients are receiving the most value for their money. We want the best solution for customers based on their budgets, because it is stupid to offer a product if it if does not work within the customer's budget.

The storage efficiency provided maximum savings in our storage utilization
Pros and Cons
- "Using the built-in Snapshots and SnapMirror technology, we were able to have better working data protection locally and off-site."
- "The storage efficiency provided a maximum savings in our storage utilization."
- "The AutoSupport could be improved to be more proactive in certain cases."
- "When getting new hardware, always tell the account manager that you are also considering other brands. They will be forced to adjust the price lower."
What is our primary use case?
We recently upgraded our NetApp environment from 7-Mode to Clustered ONTAP v9.3. Primary use cases are NFS and CIFS. NFSs are used for VMware data store while the CIFSs are for corporate file sharing.
How has it helped my organization?
Using the built-in Snapshots and SnapMirror technology, we were able to have better working data protection locally and off-site. The storage efficiency also provided maximum savings in our storage utilization.
What is most valuable?
- Snapshots
- SnapMirror
- Storage efficiency
Other tools, like OnCommand Unified Manager and Config Advisor, help us a lot in managing our environment.
What needs improvement?
None at the moment for the box itself. We are very happy with the current capabilities of this hardware.
Hopefully, the AutoSupport can be improved to be more proactive in certain cases.
For how long have I used the solution?
Less than one year.
What's my experience with pricing, setup cost, and licensing?
When getting new hardware, always tell the account manager that you are also considering other brands. They will be forced to adjust the price lower.

Provides ease of use and robust Snapshot functionality, but pricing is relatively high
Pros and Cons
- "End-users like that they can rely on the Snapshot technology so they can do their restores themselves."
- "Most valuable features are its ease of use, robust Snapshot functionality, and that you can use it in two datacenters with SnapMirror-ing."
- "It has a very good implementation of the Active Directory services, so implementation into a Windows network is easy."
What is our primary use case?
It is used as filer, for centralized file sharing. You use it, for example, for network drives from your Windows file.
Performance is very good. It's reasonably fast, probably not the fastest.
How has it helped my organization?
What the customers, the end-users, like is they can rely on the Snapshot technology so they can do their restores themselves.
What is most valuable?
- Ease of use
- Robust Snapshot functionality
- You can use it in two datacenters with SnapMirror-ing.
It has a very good implementation of the Active Directory services, so implementation into a Windows network is easy.
What needs improvement?
One thing that was missing for quite some time was the support for flash, of solid state disks, that has now improved. Another issue is the price which, compared to competitors, is quite high. The reason for switching to a different manufacturer is mostly because of the high price that NetApp has for the product.
What do I think about the stability of the solution?
The stability is good.
What do I think about the scalability of the solution?
For the use cases I have had so far, scalability has been sufficient. But I don't know where the limits are. If you go into hundreds of millions of objects, you will probably see limits. Also, performance-wise, it's probably not the fastest solution on the market.
How are customer service and technical support?
For the simple NetApp filer solution, we didn't have to use support. But for more complicated setups, MetroCluster for example, we had to call support.
I would rate technical support at eight out of 10. Support is responsive, and we could then solve our issues. It took some time. It's not the perfect support that you would get with, say, Pure or Nimble, where they collect telemetry data - they always know what's going on with the system. I think with NetApp that's not possible.
Which solution did I use previously and why did I switch?
Reasons for choosing NetApp include that it's probably the most solid, robust, and easy-to-implement solution.
Which other solutions did I evaluate?
For file servers, one alternative is Microsoft using standard Microsoft Windows Servers. Another solution is Huawei OceanStor; with the latest, version 5, they support mouse functionality.
What other advice do I have?
My most important criteria when selecting a vendor are to see that it has good market share already established, or that it has a robust roadmap with interesting products in the future, or that I have had a solid feeling with different products from same manufacturer.
If I were only rating the NetApp solution without considering the price, I would probably give it nine or 10 out of 10. If the rating includes the price, it's more like a seven.
If you're aiming for the easiest solution which will work, more or less, out-of-the-box and has lots of features, I would definitely recommend NetApp. If you're also bound by budget restraints, you should probably look at other vendors.
