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 security operating system is its most valuable feature because it's very simple, easy to use, and operate. You don't have to do very serious training to operate this equipment. It's user-friendly and pretty straightforward."
"The solution is easy to scale. I'm running two environments right now, so I need to scale. I'm running a part technology. I've got an A-side and a B-side."
"I like its speed. It has all the features that I need."
"The product cheaper compared to other solutions concerning the technology that they are using."
"Data deduplication is one feature I found to be the most valuable in the tool...Stability-wise, I rate the solution a ten out of ten."
"Cost, racial per terabyte, and speed is why we chose PureStorage. It was no brainer."
"It upgrades in place which means we'll be using it well into the future."
"It is an SSD array that has awesome performance, low submillisecond latency, and does what it is supposed to do. It just works, which is difficult for things to do anymore."
"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"
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"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"
"High performance and ease-of-management are the most valuable features."
"It performed great originally, and when it performed great, it was awesome."
"It is stable. In my three years working with the storage, I haven't seen any issues with our NetApp product."
"The most valuable features of this solution are snapshotting and cloning."
"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."
"It has a good interface. Its configuration and flexibility are also good."
"The business copy solution has become faster using SnapMirror."
"The NVMe flash cache is the most useful feature. It lowers transactional speed even more."
"The most valuable features are the speed and performance for our transactional workloads for our databases."
"It's helping to leverage data. The storage is being utilized to implement larger, complex file sizes."
"The solution could improve by having a multi-tenant feature."
"I would like to see more cloud integration."
"The integration capabilities could be improved."
"Just some nit picky stuff, like allowing servers and volumes to be grouped. Therefore, it would easier to work with them in the GUI."
"There was some complexity in the initial setup."
"I would like to see some improvements on the FlashBlade side around the CIFS space support. I am not super familiar with all the different NAS protocols that they run on their box, but there could be some improvements made on SMB CIFS side."
"I would rate this solution an eight. To make it a ten it would have to be a little cheaper."
"In the next release of the solution I would like to see Vormetric native block encryption."
"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."
"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."
"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."
"It's somewhat scalable, but maybe not so much as some of the competition."
"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."
"I need faster Fibre Channel over Ethernet. They top out at 10GBs today and I would like that to go to 40 or 100."
"The initial setup has a lot more steps in it than are probably necessary for a base deployment, unlike other vendors where it's more straightforward. It could be a little bit more streamlined."
"I don't work on the technical side of things, so it's hard for me to highlight areas of improvement, but maybe the price could be a little better."
"There is no direct storage attachment available. Most configurations require additional switches for data access."
"I think for us, improvement would probably be the changes in how the flash is actually used inside the system and how we manage the actual disk and stripes within the system."
"Their backup software could be improved."
"There is room for improvement with the user interface. There are a few things that cannot be done in the GUI. We do a lot of things through the CLI, but that's grown out of a lack of ability to do them in the GUI. An example is QTrees. You can manage them within the GUI, but the GUI is missing a few options."
"Going forward, I would like improvement in the response latencies, capacity size, cache, and controller size."
