Arnaud Salmon - PeerSpot reviewer
Offers good performance and
Once, I've been in a program, but they stopped supporting protocols like HTTP, STP, and that kind of stuff. All of the DIP supports at the beginning were kind of support when it was just Python and just five storage. And it happened a few times that the customer required the STP and HTTP protocol for storage. And I was surprised I couldn't do it anymore with NetApp. So, it would be beneficial for them to support both kinds of protocols. The only little black points that I would put on top of NetApp FAS Series. There is room for improvement in deployment and configuration processes. The thing with ONTAP is that we have a lot of layers, from the raw disks to the volumes we present to servers and configure. There are quite a lot of things to configure. Probably NetApp should ease the way to install that. In NetApp products, such as ONTAP and FAS, a solid understanding of storage is still necessary to handle configurations in larger systems. It's not the same with Pure Storage or Huawei. Even someone less familiar with storage could manage it, making it more accessible.

A stable unified storage system that enables quick access to data
The main thing Oracle can improve is the cost. It would be better if Oracle opened up the system to enable integration with other vendors. Whether it's the database, application server, or storage appliance, they should make it easy to integrate them. They need to open up more to ensure that it can work in any environment and IT ecosystem.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Most valuable features are its ease of use, robust Snapshot functionality, and that you can use it in two datacenters with SnapMirror-ing."
"​NAS stability"
"The best feature is its ONTAP product line for Ransomware protection. It also has features for file storage and block storage. The solution is stable. We've had no issues with it. The tool is scalable and meets our requirements. The technical support and the supporting partner are great. The initial setup is straightforward. It is very easy to maintain the product. The feature set is excellent. I recommend the solution."
"They are very satisfied with NetApp and continue to use NetApp and upgrade to new solutions."
"The new FAS series is a good fit for some customers. We have good performance and capacity, even though it is full flash."
"The solution is stable."
"Saves space with deduplication"
"Adaptive balancing is a valuable feature."
"I like its storage capacity, quick access to the data, speed, and overall storage management."
 

Cons

"The product should improve its user experience."
"One area that needs improvement is the hyper-converged solution. Although NetApp has a solution, compared to Nutanix, it falls short."
"They should add new features to the product."
"The high cost of the product is an area of concern, so from an improvement perspective, the tool needs to be made cheaper."
"The only downside is in ease in management; it is not easy to use."
"It could be more flexible in terms of configuration."
"When we were going through all the MFA hardening and the anti-ransomware setup, I gave some feedback to our executive. The MFA process for getting that set up on the AFF systems was cumbersome compared to some of our other systems."
"The adoption of the cloud in Argentina is very slow. Customers do not move most of their applications to the cloud. Moving applications is a simple task, but the cost is a concern in Argentina. There is an opportunity there for NetApp with Cloud Volumes ONTAP."
"The main thing Oracle can improve is the cost. It would be better if Oracle opened up the system to enable integration with other vendors. Whether it's the database, application server, or storage appliance, they should make it easy to integrate them. They need to open up more to ensure that it can work in any environment and IT ecosystem."
 

Pricing and Cost Advice

"It’s difficult for us to get money, so make sure you get everything in order, because there’s no going back and saying “oh, I missed this or that”, so make sure you plan well and well in advance."
"The solution’s cost is reasonable."
"We purchased it for four years, and it wasn't expensive. It was reasonable. Every company has a different agreement with NetApp. We got everything we wanted with all the bells and whistles and all the features and functionalities."
"Cost effective storage for all performance levels (including all-flash)."
"NetApp FAS Series' pricing is competitive."
"The pricing of NetApp FAS Series is reasonable for its performance."
"It is expensive."
"The tool is expensive."
"The price could be better. We have many competing products now like Huawei and Dell EMC, and these are slightly cheaper."
