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 most valuable features are the replication of data and the continuous snapshot that we can take from the disc."
"The connections are a lot faster than what we had in the past. One InfiniBand does what we did on all of our Fibre Channels."
"With Pure Storage, we don't see any latency or IOPS. It has been a very seamless integration."
"The GUI is very easy to use and intuitive."
"Performance, deduplication, compression, and fast response time for requests from servers and applications."
"It upgrades in place which means we'll be using it well into the future."
"Simplicity and reliability are the most valuable feature of Pure Storage FlashArray."
"Access speed and power consumption are most valuable."
"It performed great originally, and when it performed great, it was awesome."
"The initial setup is straightforward."
"Data Compression: Up to 80% space reduction in the database"
"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."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"Tech support has been absolutely amazing. I think on the technical aspects as well, my staff is able to get great support from the NetApp technical support resources that we have. What I love about NetApp is they have a health care division. At times, it's such an amazing thing because if we have a healthcare-related issue, there's no one better than having prior CIOs from health care organizations that NetApp has hired, and that are part of the health care team, to help out with any of those initiatives and support problems. Support has been absolutely phenomenal."
"Switching to AFF has improved the performance of a lot of our virtual machines in a VMware environment. The number of support tickets that we receive has fallen to almost zero because of this, so it's been a real help for our virtual server support team."
"I think it is a very stable product."
"The most valuable feature is speed."
"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."
"Its consistent stability is one of the things that I like, and the performance is also very good."
"The most valuable features are the performance and the storage efficiency, due to the compression and deduplication... The efficiency is very important because we can buy fewer disks for more data."
"Setting up storage for an application (storage provisioning) is quick and easy. Maybe a quarter of the time is now spent getting the application up and running, or even less."
"Beyond a certain amount of petabytes, you have to have a separate system. Basically, it's not infinitely scalable."
"The solution could improve by having a multi-tenant feature."
"The integration capabilities could be improved."
"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."
"I would like to see a Nagios monitoring plugin which watches the health and performance of the system. The only one available just checks volume capacity."
"If we suddenly dump large amounts of data onto the storage system, it takes a while to process it."
"It needs to improve its price."
"It took us a year to get it to stabilize and to get the best out of Pure."
"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."
"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."
"It's somewhat scalable, but maybe not so much as some of the competition."
"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."
"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."
"When it comes to the connectivity on the back end, where the hardware is concerned—the cabling and the like—it could also be simplified to ease the communication between the nodes and between the other components of the infrastructure. I still find that a little bit complicated."
"I would like for them to develop the ability to detach the fabric pool. Once you've added it to an aggregate it's there for life and it would be nice to disconnect it if we ever had to."
"I just got through the session where it looks like they are going to support Oracle running on Linux with SnapCenter. That is one of the main things that we are hoping to get integrated."
"NetApp AFF needs to focus more on block storage. It has to focus on high-end, performance-driven applications."
"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."
"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."
"The dashboard needs improvement. The dashboard needs some uplift"
"I have experienced slow responses several times, if the ticket has only been opened in portal."
