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.
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"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 duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."
"Overall stability is very good. It is a very stable solution."
"What I really like about this program, is that it is easy to use and easy to configurate."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"The initial setup was extremely simple and straightforward."
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"Data Compression: Up to 80% space reduction in the database"
"It performed great originally, and when it performed great, it was awesome."
"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"
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"High performance and ease-of-management are the most valuable features."
"The initial setup is straightforward."
"We find the ease of usability and setup valuable."
"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."
"One of the lesser sung advantages was when we started running our interface engine on Pure Storage. The ability to process messages and pass them through in our organization skyrocketed purely because of a disk that I owned which we were getting out of Pure Storage."
"The solution offers amazing performance."
"It helps us maintain uptime much better than other solutions we've used in the past, and the support is extremely quick and responsive."
"The ease of use. That's what our customers love. They say it's very easy, they don't need special training, they don't need to call us or any other company or integrator to help them do their job. That's the main reason they purchase Pure."
"It comes with a large number of features out-of-the-box, which makes it easy for us to see problems and manage capacity."
"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."
"It is on the expensive side."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."
"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"The software layer has to improve."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"The tool's pricing is higher than competitors."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"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."
"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."
"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."
"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."
"The backend of this solution utilizes an Active/Passive architecture, rather than an Active/Active architecture, which is a disadvantage, when compared to some of its competitors. Its storage capacity should be expanded in the next release."
"The support for NFS protocols right out-of-the-box need improvement. I'm used to other storage vendors who have NFS support right out-of-the-box, and Pure Storage doesn't seem to have anything."
"Its price could be cheaper. It is not the cheapest one out there, but I'm not directly involved in the figures and negotiations."
"Had some issues with Purity not being entirely compatible with VMware ESXi."
"What it needs to do is work a little closer with solutions, like VMware, so it understands the particular workloads that are on it. Today, it does not understand the applications which are running against it."
"CIFS and SMB Shares cannot be mounted directly."
"As partners, we should have the option to download the software, rather than have to go back through Pure to obtain it."
"I would like to migrate to the cloud in the future and know how that would actually work with this product."
