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.
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"The most valuable feature of this solution is reliability."
"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"One of the best features is the support, which is excellent."
"The initial setup was extremely simple and straightforward."
"The most valuable features of this solution are its ease of use and performance."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"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."
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"High performance and ease-of-management are the most valuable features."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"The initial setup is straightforward."
"Data Compression: Up to 80% space reduction in the database"
"It is easy to manage. You don't have to have the same people who used to manage the Dell EMC arrays because the solution is more intuitive."
"The top-tier support and reliable storage are the most valuable features of this solution."
"The speed is the most valuable feature of this solution."
"All our junior partners can administer the storage arrays. It is simple and easy to use. We don't have to dedicate a whole team of full time people to work on it."
"The predictive performance analytics is a very good feature, as our system is performing better than before."
"It upgrades in place which means we'll be using it well into the future."
"Because we were able to afford to go all flash, we don't manage the tiers, we're not moving data up, and we're not waiting for overnight cycles."
"It helps simplify storage. When you're running Pure all-flash, you don't have to do a lot of the old Oracle best practices. You don't have to worry about putting log files on a different disk channel than the data files, and those types of issues... That has made it vastly easier to do large volumes, rapid provisioning in databases, without taking a performance hit."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"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 terms of what needs improvement, the dashboard and management could be simplified."
"They could add more support for file storage and different types of storage."
"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."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"In the future, I would like to see integration with enterprise backup systems."
"It is on the expensive side."
"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."
"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."
"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."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"Pure Storage FlashArray could improve the recent file storage capabilities because it is lacking a lot of features."
"The solution could improve by having a multi-tenant feature."
"I would like to see more detailed reporting on the data. However, it would be nice to know what are the exact VMs usage after deduplication and/or what that VMs actual latency and bandwidth is, outside of VMware."
"I would rate this solution an eight. To make it a ten it would have to be a little cheaper."
"From a scalability perspective, it is a very small storage solution, so it's not very expandable."
"Currently, the solution fails to support file screening."
"The time-to-market could be better at times, but I think that's true for all vendors of hardware."
"I can't see where they can make anything better, unless, of course, they lower their prices even more."
