We performed a comparison between DDN IntelliFlash and NetApp AFF based on real PeerSpot user reviews.
Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."One of the features that my customers are really interested in is immutable snapshots. There are immutable snapshots to which your applications can be reverted back if you are hit by some kind of ransomware threat or malicious attack. That's kind of a key deal, and it is one of the selling points I use to point out to my customers the value and the features that Pure Storage brings to the table."
"Most of the problems that we had in the past with the performance in IOPS have disappeared. It has been a great improvement for our customers' services."
"This solution has helped my organization by cutting down on provisioning time. I used to have to provision a VM and it would take ten minutes. Now, it takes thirty seconds."
"Lone segmentation is simpler and more agile. It's improved the velocity in overall provisioning from project to operation."
"The first set up we had was really straight forward and simple."
"On a scale of one to ten, where ten is the most comfortable pricing, I rate the solution a nine out of ten."
"The first year, we started out with one or five terabytes and it took what was 20 terabytes of storage down to less than one terabyte."
"It gives us capacity planning."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"The initial setup is straightforward."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"It performed great originally, and when it performed great, it was awesome."
"Data Compression: Up to 80% space reduction in the database"
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"High performance and ease-of-management are the most valuable features."
"Performance is excellent. In fact, it's so fast that we're not really even taxing it all that much."
"AFF has improved my organization because we now have better performance. We can scale up and we can create servers a lot faster now. With the storage that we had, it used to take a lot longer, but now we can provide the business what they need a lot faster."
"The stability is solid. It doesn't fail on us, which is exactly what we want. We are in a critical business that we can't have any percentage of downtime."
"The most valuable feature is the ease of management."
"We can go through and do an upgrade without worrying about any issues with the process"
"We just migrated two petabytes of data storage from IBM over to NetApp All Flash. Some of the performance improvement that we've seen is 100 times I/O and microsecond latency."
"This solution makes everything a lot faster. The time to move data around, boot and migrate VMs is much faster."
"NetApp tech support is so good. Their tech support has always been so stable and the people are so good in case of any failure or any good feature that needs to be updated or features that supposedly can help with performance to improve some performance. NetApp support is one of the best that I deal with."
"It goes at about 95 percent, so we have had some performance issues. It is hard to clear them."
"If they could make it cheaper, that would be something."
"The solution could improve by having a multi-tenant feature."
"We haven't seen ROI yet."
"I would like to have an easy way to determine the cost per VM so that I can present a solution to our customers."
"In the next release of the solution I would like to see Vormetric native block encryption."
"Data reduction is an area that needs improvement. There is a garbage collection service that runs but during that time, system utilization increases."
"A minor issue that comes to mind is that, every once in a while, a hard drive will go bad."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"It's somewhat scalable, but maybe not so much as some of the competition."
"Snapshots are not as easy to access as on a NetApp device."
"In the proxy section you can’t choose a user account and password, so it is not allowed at the moment to go out, if customer has such constellation."
"Performance is horrible now. Our original intent was to buy new storage in about two years. But since it became a critical urgency for us, we decided to purchase a new one in two or three months."
"We had just one small stability problem with power flapping and it did not start up again automatically. We had to access service ports and manually restart the storage processors."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"It has not reduced our data center costs. NetApp charges a pretty penny for their stuff."
"When you look at the competitors, they have some features available, for example on the deduplication side."
"I would like to see aggregate level encryption in the next release. This is critical."
"Additional performance, additional data efficiencies, that's what everybody wants right now."
"The response to basic problems could be faster. They usually respond fast when there are critical issues, but you always want it right now."
"During the initial setup, you need to know what you are doing."
"We only had a few upgrade issues."
"NetApp should have a local presence in Pakistan."
