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."It has improved my organization because now have lower latency, we get fewer complaints from customers, and we see a constant response time."
"It gives us capacity planning."
"Pure Storage FlashArray has significantly improved our data center performance. It handles high workloads efficiently, providing better performance in the environment. With increased storage capacity, it has led to improved overall system performance. The tool's technology is a standout feature. It has helped me reduce storage costs by 15 percent."
"The most valuable features of Pure Storage FlashArray are management and administration user-friendliness, provisioning, and performance."
"The technical support is very good."
"The management features are well organized and they have a very good dashboard."
"It helps simplify storage. When you're running Pure all-flash, you don't have to do a lot of the old Oracle best practices. You don't have to worry about putting log files on a different disk channel than the data files, and those types of issues... That has made it vastly easier to do large volumes, rapid provisioning in databases, without taking a performance hit."
"Their REST API is wonderful, well-documented, and easy to use."
"The initial setup is straightforward."
"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"
"It performed great originally, and when it performed great, it was awesome."
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"High performance and ease-of-management are the most valuable features."
"It is a stable solution."
"I would say the consistency with the ONTAP versions and the speed and performance from the flash."
"When we move to all-flash, our response times were reduced to microseconds."
"I think that the DR applications are the most valuable, including Snapshots and SnapMirror."
"There are many reports accessing the applications. We receive them very quickly. We used to wait a long time for them. Now, you just need to wait a moment."
"It's pretty scalable. It can scale up to 24 nodes."
"Its consistent stability is one of the things that I like, and the performance is also very good."
"My favorite part is all-flash solid drives. All of my applications are running on an all-flash array. Before, we used to get too many severity tickets on performance, but as soon as we migrated everything to an all-flash array, our critical applications are at top performance."
"I can't see where they can make anything better, unless, of course, they lower their prices even more."
"It was a little costly. The price was ultimately higher than both of the other solutions that we evaluated. I'd say that's the only downside."
"If we suddenly dump large amounts of data onto the storage system, it takes a while to process it."
"A minor issue that comes to mind is that, every once in a while, a hard drive will go bad."
"The only time that we had problems with it was that there was a bug in the VVol implementation but, outside of that, it has been flawless."
"I would like to see active replication. I know that it's available now but I haven't tried it yet. I hope that it works."
"The connectivity needs improvement. You do not have the possibility to have a file and block connectivity at the same time on the same machine. It has limited ability to do so."
"Pure Storage FlashArray could improve the recent file storage capabilities because it is lacking a lot of features."
"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."
"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."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"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."
"Going forward, I would like more performance analytics on it, on the area itself, instead of using some other tool."
"We would like to have NVMe on FabricPool working because it broke our backups. We enabled FabricPool to do the tiering from our AFFs to our Webscale but it sort of broke our Cobalt backups."
"You have a limit in terms of how much you can expand storage. It sounds like a lot. However, over the years, as you grow, it may be smaller than you think."
"To be more competitive in the industry, they can develop deduplication, compression, and smarter features in the same array instead of all-flash."
"We don't have many issues related to the appliance itself. In terms of the OS, we do get some hiccups here and there."
"In future releases, I would like to see the ability to automatically mount SMB shares and file systems."
"We have had issues with CIFS presentations and outages, so if that was removed, we could do seamless upgrades without affecting CIFS presentations. That would be an advantage. That's about the only improvement I can think of."
"Something I've talked to NetApp about in the past is going more to a node-based architecture, like the hyper-converged solutions that we are doing nowadays. Because the days of having to buy massive quantities of storage all at one time, have changed to being able to grow in smaller increments from a budgetary standpoint. This change would be great for our business. This is what my leadership would like to see in a lot of things that they purchase now. I would like to see that architecture continue to evolve in that clustered environment."
