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."Technical support has been amazing."
"We are very happy with the data deduplication and compression ratio that we have on the platform."
"The management features are well organized and they have a very good dashboard."
"Technical support is good."
"The most valuable feature is it never goes down. We can expand and create volumes."
"This solution has improved our organization. In the past, we had reports that were taking up to two hours and after switching to SSD storage the overall processing power dropped to half an hour. The end users saw an immediate performance gain."
"Its array houses our entire production environment."
"The technical support is very good."
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"Data Compression: Up to 80% space reduction in the database"
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"The initial setup is straightforward."
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"It performed great originally, and when it performed great, it was awesome."
"High performance and ease-of-management are the most valuable features."
"Replication would be one of the most valuable features."
"It should scale far beyond our needs. I don't think we will ever hit the edge of it."
"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."
"NetApp AFF is based on Unix, which makes it secure."
"The most valuable features are deduplication and compression, so we get more out of our storage. The replication is also important."
"It simplifies data management for NAS environments with its ease of management, ease of share creation, and Active IQ feature. These features are good overall. It helps us manage data quickly and sufficiently. Also, compression features, like dedupe, give us a good ratio."
"The cloning and snapshot features are the most valuable. With snapshot backup, we can clone a big database in minutes. We take a lot of snapshots for clients in different environments."
"We reduced our floor space by reducing 44 racks units to four rack units. It has helped us with our data center economies of scale. It reduces our support costs too, which is great."
"The higher education moves slowly. We are still looking forward to implementing the full list of existing features."
"The price of this solution could be improved."
"The initial setup of the product is complex."
"I think replication is one area that still needs improvement. Earlier, Pure Storage FlashArray only had IP-based replication. There was no API-based replication, but they have enhanced the feature now. However, they need to work on API replication for C-type of arrays."
"Part of our company works on Dell EMC because Pure Storage did not have synchronous applications when we were purchasing our products."
"I can't see where they can make anything better, unless, of course, they lower their prices even more."
"I would rate this solution an eight. There's always room for improvement, nobody is perfect to get a ten out of ten. They do what they do well. It's not cheap but we it's for uses that we needed."
"With scalability, I have run into a little problem with our last upgrade. There were some undocumented limitations to the number of drives that our controller could run on. So, instead of putting in a new data pack as we had anticipated, we had to keep adding and removing to get up to the capacity that we needed to be. What should have been a one day process (or a few hours) turned into a month and a half process."
"Snapshots are not as easy to access as on a NetApp device."
"It's somewhat scalable, but maybe not so much as some of the competition."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"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."
"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."
"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."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"It has not reduced our data center costs. NetApp charges a pretty penny for their stuff."
"It used to give us the volume where LANs should be placed when we created a LAN in the older version. However, in the newer version of ONTAP, it does not give where to place the LAN in the volume. So, that liberty has been taken away. If that was there again, it would be very good."
"A while ago, they performed quite slowly."
"NetApp AFF needs to focus more on block storage. It has to focus on high-end, performance-driven applications."
"I would like them to roll in global monitoring instead of having to buy another product for it."
"To be more competitive in the industry, they can develop deduplication, compression, and smarter features in the same array instead of all-flash."
"Implementation needs to be improved."
"The size of NetApp could be better. They're always about 40 pounds without the hard drives in them, so it would be great if there's a way to make them smaller yet keep the functionality. That would reduce the physical footprint."
