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."Non-disruptive upgrades: You can upgrade at anytime without worry."
"It upgrades in place which means we'll be using it well into the future."
"I like its speed. It has all the features that I need."
"We like the data reduction rates. That has been really helpful. You get 4U of Pure storage replacing something like two racks of spinning disks. One of the things that has contributed to that are the data reduction rates."
"The back-end data reporting for Pure Storage is phenomenal. The data that you can see on the performance of your customers' array, so you can be proactive about upgrades or enhancements, and is a phenomenal tool to have access to as a partner. I haven't seen this type of stuff out of anything of the other storage systems."
"The most valuable feature is it never goes down. We can expand and create volumes."
"It is all-flash. This makes it a lot faster than the rest of what we have, as it is able to drive high I/O loads, which is big for us."
"It is always out of the box, and ready to use."
"High performance and ease-of-management are the most valuable features."
"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"
"The initial setup is straightforward."
"It performed great originally, and when it performed great, it was awesome."
"Data Compression: Up to 80% space reduction in the database"
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"We recently started using the volume encryption feature, which is helpful because there are some federal projects that require data at rest to be encrypted."
"The most valuable feature is the ease of management."
"Supports file formatting, the main protocols, and the hot swapping of disks and features."
"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 most valuable features are the flexibility and level of technical support."
"I would say the consistency with the ONTAP versions and the speed and performance from the flash."
"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."
"It also helps to accelerate databases in our environment. First of all, there is the reliability of things staying online and the small response time as well, from the MetroCluster, for all of the data that we're serving; and the applications are talking to the MetroCluster. It provides a very fast response time."
"I would rate this solution an eight because we have had outages. The commit times went very high in the database. The whole array went down so our customers were down for around eight hours. This was a very big outage which could have been our fault because we didn't do the upgrade in time."
"It needs to improve its price."
"When we were doing some tests, we found that there was an I/O freeze when they were switching the controller."
"There's always an opportunity for new feature functionality."
"CIFS and SMB Shares cannot be mounted directly."
"The problem is that we can only make a few groups, around five or six groups. I like groups and we need a lot of them. We had to put all the information in only a few groups and cannot make a more detailed separation of them."
"The file functionality could be better."
"We would like to integrate it more with our backup solutions."
"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 only keeps one hour of real-time data without the ability to do deep analysis of each element."
"It's somewhat scalable, but maybe not so much as some of the competition."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"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."
"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."
"It would be nice to have better integration between SRM and VMware, as I've had some issues with that."
"They should make these features a little more affordable."
"In future releases, I would like to see the ability to automatically mount SMB shares and file systems."
"In the past, NetApp designed it so that you have a 70% threshold. You would never fill up past 70% since you need to have that room available. Whereas with Pure, I can fill it up to 110% of what they listed and it's still going at full speed. NetApp can't do that."
"Their backup software could be improved."
"Going forward, I would like improvement in the response latencies, capacity size, cache, and controller size."
"The price of NVMe storage is very expensive."
"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."
