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 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."
"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."
"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."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"Pure has signature security technology, which cannot be deleted, even if you are an administrator."
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"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."
"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."
"It performed great originally, and when it performed great, it was awesome."
"Data Compression: Up to 80% space reduction in the database"
"This solution has improved our organization in the way that we used to see latency but now with this solution we don't. It also has good performance. Latencies have come down for our performance in the SQL databases. We can put a lot more in a lot less in terms of space savings. We also save data center space have good deduplication."
"The mobile app is very helpful."
"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."
"Performance, dedupe, and that it works well with database workloads are its most valuable features."
"Most of the problems that we had in the past with the performance in IOPS have disappeared. It has been a great improvement for our customers' services."
"The initial setup is very straightforward. You simply plug it in and turn it on."
"Cost, racial per terabyte, and speed is why we chose PureStorage. It was no brainer."
"As soon as we introduced our first Pure Storage FlashArray, the first benefit was at least twice the performance increase. Our production databases simply ran twice as fast with no other change."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"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."
"I'd like to see the product implement active replication for vehicles such as VMware."
"The tool's portfolio is minimal. It is expensive."
"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."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"We need better data deduplication."
"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."
"Snapshots are not as easy to access as on a NetApp device."
"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."
"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."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"With scalability, I have run into a little problem with our last upgrade. There were some undocumented limitations to the number of drives that our controller could run on. So, instead of putting in a new data pack as we had anticipated, we had to keep adding and removing to get up to the capacity that we needed to be. What should have been a one day process (or a few hours) turned into a month and a half process."
"I would like the ability to swap out the network adapters into it. So, without taking out the whole controller, I would like to be able to swap adapters. This would make things easier."
"They are doing some stuff with containers and an object search. These could be improved, because containers is one of the main topics that we are talking with our customers about."
"FlashArray's capacity for forecasting should be improved because it needs to be a bit more current. I think it's bundled with the deduplication and other compression factors. We need more user interfaces for forecasting in this software and more interfaces need to be integrated with this array management tool."
"Beyond a certain amount of petabytes, you have to have a separate system. Basically, it's not infinitely scalable."
"It is a bit expensive."
"The GUI is simplistic and basic. I feel like it's explanatory, but not enough, it needs a little more to it."
"Just some nit picky stuff, like allowing servers and volumes to be grouped. Therefore, it would easier to work with them in the GUI."
