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."The solution is very reliable."
"The most valuable feature is how it simplifies the management of the SAN."
"Support has been helpful."
"The scalability options are very nice because you can scale it much better and faster. The scalability was there in the previous environment also, but this is far better than what we had before. It basically helps the user in case they are looking for more storage. We can scale it much faster."
"It simplifies storage."
"Simplicity and reliability are the most valuable feature of Pure Storage FlashArray."
"The mobile app is very helpful."
"The most valuable feature of Pure Storage FlashArray is the complete set of functions it provides."
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"Data Compression: Up to 80% space reduction in the database"
"The initial setup is straightforward."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"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."
"It performed great originally, and when it performed great, it was awesome."
"Setup was simple and easy."
"The speed is great. That's probably number one in terms of features we appreciate."
"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."
"Our architecture has historically relied on RDMs, so AFF has enabled us to easily migrate from our old EMC PowerMax to the new NetApp. It's been pretty smooth. We have a lot of SAP servers in our environment, so performance is critical for us."
"It is stable. In my three years working with the storage, I haven't seen any issues with our NetApp product."
"In terms of the footprint, it is far more efficient. It has smaller, higher-capacity drives than our older unit. In terms of space, power, and cooling, it has simplified things."
"The speed of data retrieval is the most valuable feature. We mostly use it for our SAP database and we are getting good IO from the hard drive."
"The initial setup was straightforward."
"It needs to improve its price."
"They are doing some stuff with containers and an object search. These could be improved, because containers is one of the main topics that we are talking with our customers about."
"Pure Storage FlashArray could improve some aspects. There are certain features that are good and there are some features that I see some issues with at the technical level. Those issues are related to replication. They need to resolve those issues, which I have already highlighted to the Pure team. Additionally, there are some issues in the active cluster that could improve."
"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."
"It took us a year to get it to stabilize and to get the best out of Pure."
"They could improve the price."
"I would like to see support for NVMe, end-to-end."
"A minor issue that comes to mind is that, every once in a while, a hard drive will go bad."
"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."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"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."
"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."
"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."
"When you look at the competitors, they have some features available, for example on the deduplication side."
"Going forward, I would like improvement in the response latencies, capacity size, cache, and controller size."
"We would like to have more behavioral reporting."
"I need faster Fibre Channel over Ethernet. They top out at 10GBs today and I would like that to go to 40 or 100."
"One of the features that I am looking for, which is already in the works, is to be able to take my code and automatically move it to the cloud."
"NetApp should have a local presence in Pakistan."
"In future releases, I would like to see the ability to automatically mount SMB shares and file systems."
"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."
