Helps to save money and resources with the data compression feature
One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them. One way to improve the product is to add an operational assistant that doesn't depend on VMware. It could also establish more alliances with other operational systems.

Flexible with great support and high-speed multi-protocol storage
Keystone offers flexible consumption models that go beyond just how much capacity at such and such a speed, et cetera. We don't always know what the profile of that data will be. However, if we can quickly agree on terms that meet our needs and make NetApp still reasonably profitable, we can confidently deploy, see how things go and adjust. That kind of service delivery model, that customer service model has sped things up and made contract negotiations much easier. It frankly made the owners of the system more confident. We've experienced faster time to market. It's hard for us to find and retain infrastructure staff. We're in a business where the firm fixed price contract reigns supreme, and so we can't always just offer someone more money. However, if they can dedicate their time to learning one company's portfolio and learning it really well, but be useful in a bunch of different places, they will do well. We've seen that in a lot of different places. We've been able to hire younger people and retain them, moving them from program to program based on their understanding of the solution its skill set, and its portability. It's been useful for high-speed multi-protocol storage in places with ever-increasing density. We have limits on how much power and cooling and rack space we have, and yet they've delivered every time. We needed a storage company that had mastery of multi-protocol, and this solution stands out. They especially stand out as a secure provider. We require solutions that we can run ourselves, that we can air gap since so much of what we do is either classified or very sensitive or cannot live in a public ecosystem. For us, the issue consuming AI has been the trust of the models given to us by third parties. We can't necessarily trust their provenance, what fed them, what originally trained them, or what gave them their worldview, for lack of a better term. We can't simply just trust that at face value since we know nothing about where it came from or what inferences it might make. We must assume that some AI inferences were made deliberately to damage or hurt national security systems. So the models that we start with tend to be very, very primitive, crude, and not well trained, so we have to train them much longer and not always with the availability of cloud that has inexhaustible capacity. A partner who understands this and provides consistency at all scales is very important.

Used for VMs with replication a feature, but need upgraded SSDs
We use this solution. I configured and updated it. Of course, I was also a user of applications that store data on that storage. We already have an SSD solution. So, rather than planning to go with an SSD solution, we are focusing on expanding it. If a company wants to deploy something new, it should choose a product with SSD, and NVMe disks. Overall, I rate the solution a six out of ten.

Quotes from Members

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

Pros

"I appreciate the performance."
"What I really like about this program, is that it is easy to use and easy to configurate."
"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"We are satisfied with the performance as it is significantly faster compared to traditional storage options."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"The most valuable feature of this solution is reliability."
"Overall stability is very good. It is a very stable solution."
"The newest version of ONTAP has a bit of a learning curve because you need to learn where things are to find them. It is not impossible, but when you are accustomed to the older version of ONTAP, it just takes a bit getting used to it, but it is about the same as before."
"The features that I found most valuable are SnapMirror and SnapVault; these provide DR and backup for data redundancy."
"Data efficiency is the most valuable feature because of the dedupe and compression."
"We have a comprehensive solution that could accommodate anything. We can fly it earlier and get them in the air testing and prototyping much faster than they could have with other solutions."
"I like some basic features like Snapshot, FlexClone, and advanced features such as SnapMirror, and SnapVault. They also recently enhanced the market with Cloud Volumes ONTAP. I think that NetApp is a very good product."
"The biggest benefit of NetApp AFF is the performance."
"The most valuable feature is the ability to do QoS."
"The most valuable features are the flexibility and level of technical support."
"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."
"The most important features are SnapVault, Snapshots, and SnapMirror."
"At the moment, we use NetApp SnapMirror to replicate data to another filer at an offsite location for backup. So, I like this feature."
"Most valuable features are its ease of use, robust Snapshot functionality, and that you can use it in two datacenters with SnapMirror-ing."
"Good for NAS and unified solutions."
"The replication feature is noteworthy because it's faster than most and it uses little bandwidth. Then there's the friendly interface that the equipment offers. With this interface, it is very easy to manage."
"The solution's most valuable feature is its absolute reliability."
"It changed the way we do Disaster Recovery (DR) around NetApp replication."
 

Cons

"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"Maybe the price can be reduced since the solution is very expensive."
"The UI for this solution needs to be improved."
"There is room for improvement in the pricing of the product."
"It is on the expensive side."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"The tool's portfolio is minimal. It is expensive."
"Adding some functions to the product would be beneficial."
"We have had customers asking about S3 support for a while now. I heard that is coming in one of the next versions. So, I would like to see S3 targeted support on the FAS system."
"We have had trouble with restoring applications, and if there is more support for application-aware backups then that would be great."
"On the fiber channel side, there is a limit of sixteen terabytes on each line, and we would like to see this raised because we are having to use some other products."
"It can get a little expensive if you need to add more disks. The cost is a pain point for us, especially in terms of expansion."
"ZAPI is kind of difficult to use. You know, it's SOAP-like, it's not really SOAP. I would like to see it more of a REST-based JSON, instead of XML."
"On the roadmap, NetApp is improving the solution's storage efficiency, compression algorithms to achieve more space savings, and the management interfaces. We are looking forward to these feature additions in the next release."
"The product should be more competitive and come up with additional features. They should keep the client always in mind and as the top priority. This would be the best way to compete with other solutions."
"The NetApp support could be better."
"I would like to see NetApp add incident support."
"The only downside is in ease in management; it is not easy to use."
"A big problem with physical appliances is that updating them can be a bit burdensome."
"We are not able to connect to the support of NetApp from Sudan. We have to go through many agents for support, which makes it difficult."
"There are some technical limitations, but it would be great to have in-line deduplication and in-line compression for the FAS series as well."
"Installation of the additional switches and ETP could be improved."
"The user interface could be improved."
"Needs to improve the adaptive storage quality of service."
 

Pricing and Cost Advice

"The licensing is on a yearly basis."
"We pay approximately $50,000 USD per year in licensing fees."
"Its price could be better. It is not too expensive, but it is the high-end cost. It is kind of a Rolls-Royce. You pay a lot, but you get a lot out of it. So, the price pressure on the way down would be great, but at the end of the day, if you need to do the work, you just pay for it."
"The tool is an investment that we've budgeted for. While the prices may be higher than those of other vendors, we see it as a market leader with benefits. We don't regret purchasing it."
"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."
"With Pure Storage, we would like to continue seeing price reductions with flash storage. I don't think we're any different than anybody else when we continue to look to the industry for price reductions of both NVMe and traditional SSD storage. We would like to see these prices continue to decline and erode, even displacing large spinning disks."
"Our licensing fees are $500,000+ USD."
"As far as the licensing costs, everything is included in the license."
"The pricing is good."
"NetApps offers a lot of different options. Just take your time and work with the consulting teams. Lay out what your needs are to ensure you are purchasing what will help you be successful."
"Obviously depending on the price point, NetApp is obviously a little more expensive than your generic Dell SAN solution or whatever."
"Planning of all the lifecycle storage with NetApp AFF is part of the solution. While it is not cheap, they have introduced a new series of AFF that are more affordable, providing options for more users."
"If you go for Replication, Vault, and NAS, please ensure that the license has been ordered at the very beginning. However, licenses can been added or modified without rebooting the system at any time."
"The total cost of ownership has decreased a great deal. As far as percentages, it's hard to gauge, but we did have quite a few personnel staying up, making sure batches ran well every night. Now, batches are being done by 8:00 in the evening, so we don't have to do that anymore. When you start adding the employee hours that we have for people working in the off-hours, and it is not an issue anymore, I suspect TCO might have gone down 25 percent."
"It is relatively cheap compared to other vendors."
"I would like it to be a lot less expensive, but it's been a very good solution for us."
"The solution’s cost is reasonable."
"I don't recall the price, but in general, pricing can always be better."
"The product is on the expensive side."
"The process for going to cluster mode is expensive."
"The tool is expensive."
"We are on a perpetual license."
"In general, I find NetApp to be very expensive. That's the main issue I have with them. So it's a drawback in terms of pricing."
"I've sold arrays for as little $20,000 USD and as high as $300,000 USD."

NetApp vs. XtremIO
Is there another storage platform as feature rich as NetApp FAS? I think it is fair to say that NetApp FAS running Clustered Data ONTAP is a very feature rich platform – the move to the clustered version of ONTAP has brought many next-generation features including Scale-out and Non-disruptive…
