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."We consume less physical storage because of the solution’s deduplication and compression."
"The performance of the storage is just unbelievable."
"We find the ease of usability and setup valuable."
"They are quite responsive and our local team was pretty good."
"The most valuable feature is it never goes down. We can expand and create volumes."
"The solution has probably reduced my power use substantially."
"My rating of Pure Storage is a ten out of ten because of the price for performance and footprint - the overall value."
"I never have to worry about its performance or if it is the root cause of an issue."
"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 provides a combination of all the protocols that you need, without losing deduplication and compression."
"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's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"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."
"Its consistent stability is one of the things that I like, and the performance is also very good."
"Technical support has been okay."
"The most valuable features are the ease of administration and configuration, as well as the speed of deployment."
"Things that have been really useful, of course, are the clustering features and being able to stay online during failovers and code upgrades; and just being able to seamlessly do all sorts of movement of data without having to disrupt end-users' ability to get to those files. And we can take advantage of new shelves, new hardware, upgrade in place. It's kind of magic when it comes to doing those sorts of things."
"The most valuable features of this solution are snapshotting and cloning."
"The most valuable feature of AFF is that it offers better visibility and control over performance, ensuring it meets customer needs effectively."
"We found AFF systems very competitive in terms of performance, storage efficiency, feature richness, and scalability."
"I would like to have an easy way to determine the cost per VM so that I can present a solution to our customers."
"We haven't seen ROI yet."
"I would like to have support available in Spanish."
"I would like some performance analytics which go deeper than today. It should be specific to some hosts and applications. This would be good."
"It's too early to tell if we've seen a reduction in total cost of ownership. The solution is expensive."
"We would like to see better troubleshooting aspects. It helps us if we can find out where the problem is. Right now, it's difficult. Sometimes it's difficult to pinpoint the issue. If they had more visibility and more troubleshooting feature built into the tool that would really help."
"Pure Storage FlashArray could improve by being more secure."
"They could improve the price."
"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."
"Snapshots are not as easy to access as on a NetApp device."
"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."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"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."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"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."
"The support documentation has room for improvement."
"The graphical interface is still heavy and slow. Needs more improvement in this area."
"Tech support is a place where there is room to improve the product experience. The response time when they are busy is not very good."
"The quality of technical support has dwindled over time and needs to be improved."
"Tech support is great with NetApp if you can get past Tier 1. A lot of times when you open a new case or do a direct dial-in with an issue, like with any support, you will definitely reach a Tier 1 level that is not particularly helpful until you get escalated to an expert."
"Better stability, not releasing features until they are fully functional, or at least giving us a software train that doesn't add them until they are fully functional and proven."
"AFF could introduce different subscriptions on the platform."
