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."At this point, I don't know anything that they could provide in a better way."
"The code upgrades are very smooth."
"It's simple, powerful, and ready to use."
"We consume less physical storage because of the solution’s deduplication and compression."
"We have seen savings in our storage. The speed of deployment has gone from several days to a few minutes. This product has reduced that time into minutes, simplifying storage for us."
"The best feature is consistently lower latency, even when IOPS crank up to over 75K. The product maintains submillisecond response time, which is incredible."
"With Pure Storage, we don't see any latency or IOPS. It has been a very seamless integration."
"The deduplication and compression rates are beyond impressive."
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"The initial setup is straightforward."
"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."
"Data Compression: Up to 80% space reduction in the database"
"It performed great originally, and when it performed great, it was awesome."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"High performance and ease-of-management are the most valuable 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."
"It has a good interface. Its configuration and flexibility are also good."
"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."
"The most valuable features are the flexibility and level of technical support."
"We have had issues before on our infrastructure where 20 to 30 percent of the people would come to us pointing the finger at the storage technology or storage back-end. That is now virtually zero."
"It is a stable solution."
"NetApp AFF's flash technology offers great performance. This feature has been my go-to for managing data and ensuring speed and reliability."
"Our AFF 8040 is currently helping us in terms of response time and speed because it is a flash system. Most importantly, it enables our SQL Cluster to respond to database queries and things a lot faster. It minimizes latency."
"Pure Storage FlashArray could improve by being more secure."
"FlashArray's capacity for forecasting should be improved because it needs to be a bit more current. I think it's bundled with the deduplication and other compression factors. We need more user interfaces for forecasting in this software and more interfaces need to be integrated with this array management tool."
"Part of our company works on Dell EMC because Pure Storage did not have synchronous applications when we were purchasing our products."
"Pure Storage FlashArray could improve the recent file storage capabilities because it is lacking a lot of features."
"Areas for improvement would be the financial operations. In the next release, I would like to see a NAS protocol included."
"It needs to improve its price."
"They should work on their upgrades, they're not smooth."
"On a couple of occasions, the waiting time for an upgrade has been pretty substantial."
"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."
"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."
"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."
"Snapshots are not as easy to access as on a NetApp device."
"There is no direct storage attachment available. Most configurations require additional switches for data access."
"A while ago, they performed quite slowly."
"NetApp could focus even more on the configuration."
"NetApp should offer more training so everyone can learn about the products. Other vendors have a lot of training options. It would be great if NetApp would highlight how to use the features more so that every admin or person can gain more knowledge about this technology."
"I would like to see better tutorials available, beyond the basics, that cover subjects like MetroCluster and automation."
"There is room for improvement in terms of support. I have noticed that if I sometimes call their customer care for a particular issue, they will give me another number and ask me to call that other team. It would be better if they could do a warm transfer. That would save customers time from calling all the numbers again and speaking to another team."
"In terms of what needs improvement, I would like to see more consistency with the UI. It seems to change every few versions. The menus can be in a completely different place."
"The price of NVMe storage is very expensive."
