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.
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"The most valuable features of this solution are its ease of use and performance."
"The high availability of the product is the most valuable feature."
"Technical support has been helpful and responsive."
"One of the best features is the support, which is excellent."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"It has good, reliable, fast storage."
"It has benefited my organization because it has reduced time to insights."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"Data Compression: Up to 80% space reduction in the database"
"The initial setup is straightforward."
"It performed great originally, and when it performed great, it was awesome."
"High performance and ease-of-management are the most valuable features."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"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."
"The initial setup was really straight forward."
"This solution has improved our organization. In the past, we had reports that were taking up to two hours and after switching to SSD storage the overall processing power dropped to half an hour. The end users saw an immediate performance gain."
"Data deduplication features make it easier to manage storage and forecast growth."
"It worked flawlessly."
"The initial setup was very straightforward and very quick. It was up and running in our data center within 24 hours of receiving it."
"The most valuable feature of Pure Storage FlashArray is its high stability level."
"The most valuable feature of Pure Storage FlashArray is the all-flash storage performance, low latency, and efficiency of their de-duplication technology. Additionally, the ease of use is good compared to other storage systems. The features in data protection, snapshotting, and replication between data centers and sites are superior to other solutions."
"It has been very stable. I have not seen or heard of downtime storage issues after moving over to it."
"They could add more support for file storage and different types of storage."
"In the future, I would like to see integration with enterprise backup systems."
"I'd like to see the product implement active replication for vehicles such as VMware."
"The tool's portfolio is minimal. It is expensive."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"We need better data deduplication."
"The UI for this solution needs to be improved."
"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."
"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."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"Snapshots are not as easy to access as on a NetApp device."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"I would like to see data tiering to AWS."
"Pure Storage FlashArray could improve the recent file storage capabilities because it is lacking a lot of features."
"It was not proactive communication."
"We would like to integrate it more with our backup solutions."
"It is not possible to create a cluster on top of multiple arrays."
"The price should be lower."
"The price could be better."
"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."
