We performed a comparison between Pure Storage FlashArray and DNN IntelliFlash based on our users’ reviews in four categories. After reading all of the collected data, you can find our conclusion below.
Comparison Results: Based on the parameters we compared, Pure Storage FlashArray came out ahead of DDN IntelliFlash. Although both products have valuable features and can be estimated as high-end solutions, our reviewers found DDN IntelliFlash more difficult to deploy, with more capabilities for improvement, and with less reliable support.
"Technical support has been helpful and responsive."
"Overall stability is very good. It is a very stable solution."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"The latency is good."
"The most valuable feature of this solution is reliability."
"It has benefited my organization because it has reduced time to insights."
"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."
"The most valuable features of this solution are its ease of use and performance."
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"High performance and ease-of-management are the most valuable features."
"Data Compression: Up to 80% space reduction in the database"
"The initial setup is straightforward."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"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 performed great originally, and when it performed great, it was awesome."
"The stability is very good. I've done destructive testing on it and never had any type of storage outages from it."
"It helps to simplify storage because it has an easy front-end to access everything."
"This is the best all-flash storage array on the market."
"The most valuable feature is how it simplifies the management of the SAN."
"I use all the features of this solution and I find them to be easy to use and functional, such as the compression and capacity to expand."
"The management features are well organized and they have a very good dashboard."
"Data reduction and compression. Sub millisecond latency."
"We find the ease of usability and setup valuable."
"They could add more support for file storage and different types of storage."
"There is room for improvement in the pricing of the product."
"The tool's portfolio is minimal. It is expensive."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."
"I would like to see replication and DR features in the next release of this solution."
"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"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."
"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."
"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."
"The internal garbage collection process has been fixed recently in some OS updates so it is more efficient but that could be just a little better."
"If they could make it cheaper, that would be something."
"Its price needs improvement. Its price is almost double than any other flash storage solution."
"I would like to have an easy way to determine the cost per VM so that I can present a solution to our customers."
"In some cases, we get into very in-depth conversations around movement of specific data and, what's more, chunk sizes. The documentation lacked any description or information on that."
"I would like to migrate to the cloud in the future and know how that would actually work with this product."
"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 is a bit expensive."
