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 has signature security technology, which cannot be deleted, even if you are an administrator."
"The most valuable feature of this solution is its ease of use."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"Technical support has been helpful and responsive."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"The solution is very straightforward to set up."
"The latency is good."
"It has benefited my organization because it has reduced time to insights."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"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."
"Data Compression: Up to 80% space reduction in the database"
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"It performed great originally, and when it performed great, it was awesome."
"The initial setup is straightforward."
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"Scalability is one of the best features. You can quickly add more. You can swap out the drives with larger sizes, you can add more shelves. All of that is perfect - the whole concept of keeping it modular..."
"Performance, dedupe, and that it works well with database workloads are its most valuable features."
"The management is simple in Pure Storage FlashArray."
"With Pure Storage, we don't see any latency or IOPS. It has been a very seamless integration."
"It has good stability for our company."
"We are very happy with the data deduplication and compression ratio that we have on the platform."
"We also use VMware integrations developed by Pure, their plugins in our vCenter environment. They help by allowing our non-technical operations teams to deploy new data stores and resize data stores without me having to involve myself all the time to do those simple tasks."
"It allows engineers to focus on other things rather than doing the more manual tasks. It automates tasks, so the ease of use is extreme. It simplifies the storage."
"The tool's portfolio is minimal. It is expensive."
"I would like to see replication and DR features in the next release of this solution."
"We need better data deduplication."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"It is on the expensive side."
"In the future, I would like to see integration with enterprise backup systems."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"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."
"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."
"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."
"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."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"It's somewhat scalable, but maybe not so much as some of the competition."
"There are a lot of things to improve."
"Part of our company works on Dell EMC because Pure Storage did not have synchronous applications when we were purchasing our products."
"It is a bit expensive."
"Data reduction is an area that needs improvement. There is a garbage collection service that runs but during that time, system utilization increases."
"One thing I'd like to see in a future release is integration between their main storage array and what they call their FlashBlade product; to be able to snapshot directly from the primary array into multiple different backup copies on FlashBlade."
"I would like to have support available in Spanish."
"I can't see where they can make anything better, unless, of course, they lower their prices even more."
"The scalability of the solution is not as good as it probably could be."
