We performed a comparison between DDN IntelliFlash and NetApp EF-Series All Flash Arrays 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."Their REST API is wonderful, well-documented, and easy to use."
"The most valuable feature of the Pure Storage Flash Array is the blazing fast monitoring."
"It comes with a large number of features out-of-the-box, which makes it easy for us to see problems and manage capacity."
"The most valuable feature is test performance. It helps us store large amounts of data along with providing us faster retrieval of data."
"One of the features that my customers are really interested in is immutable snapshots. There are immutable snapshots to which your applications can be reverted back if you are hit by some kind of ransomware threat or malicious attack. That's kind of a key deal, and it is one of the selling points I use to point out to my customers the value and the features that Pure Storage brings to the table."
"Processes that used to take 40 minutes to two hours can be completed in five minutes."
"The management features are well organized and they have a very good dashboard."
"The deduplication in the array combined with its snap technologies allows the product to be remotely/manually controlled or scheduled."
"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."
"The initial setup is straightforward."
"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"
"High performance and ease-of-management are the most valuable features."
"Data Compression: Up to 80% space reduction in the database"
"The NetApp EF-Series gave our organization easy access to our data bases."
"The hardware and software of NetApp EF-Series All Flash Arrays are easy for us to use."
"The speed is the most valuable feature."
"It provides multi-protocol, which is what gives the edge when it comes to big lineage PC workloads."
"The stability, speed, and reliability are the solution's best features. The information is also very secure."
"I like the performance aspect of EF Series. It basically provides everything that we are looking for as a solution, very low latency and very high performance."
"Some of the valuable features include MetroCluster switchover, in terms of disaster recovery, it is easy to use, and flexible."
"Rapid deployment, easy integration management and cloning of areas."
"It's too early to tell if we've seen a reduction in total cost of ownership. The solution is expensive."
"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."
"The integration capabilities could be improved."
"Pure Storage FlashArray could improve by being more secure."
"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."
"I would love to see a true one click upgrade solution. Right now, you have to click and schedule an appointment with Pure Storage to be able to upgrade. I would love for it to automatically download, install, and fall-over every controller as it updates."
"Beyond a certain amount of petabytes, you have to have a separate system. Basically, it's not infinitely scalable."
"I think replication is one area that still needs improvement. Earlier, Pure Storage FlashArray only had IP-based replication. There was no API-based replication, but they have enhanced the feature now. However, they need to work on API replication for C-type of arrays."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"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."
"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."
"Snapshots are not as easy to access as on a NetApp device."
"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."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"We have used IBM previously. We found that the storage from IBM was poor and we chose NetApp EF-Series All Flash Arrays because it can scale very easily."
"NetApp could improve the speed of the rebuilding rate."
"Better support technicians for CAPP."
"There could be better integration with some of our Cisco products."
"I would like to have the ability to replicate data between All Flash and other NetApp storage systems."
"This solution does not have any compression or deduplication."
"The only major drawback is the replication between EF-Series units."
"The price of the All Flash solution is very high."
