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."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"One, it's easy to use and understand. You don't have to be an engineer or an expert to use this storage solution. That's the bad part of Dell PowerMAX. You have to go through very expensive education for one or two weeks and pay ten thousand dollars just to be able to use the product. With Pure Storage, you have a half-day workshop, and you know everything you need to know."
"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."
"What I really like about this program, is that it is easy to use and easy to configurate."
"Overall stability is very good. It is a very stable solution."
"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."
"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."
"High performance and ease-of-management are the most valuable features."
"Data Compression: Up to 80% space reduction in the database"
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"It performed great originally, and when it performed great, it was awesome."
"The initial setup is straightforward."
"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."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"It reduces space and the polar consumption. It also accelerates the application."
"We've had different types of storage, and three things of this solution are valuable. The first one is its outstanding performance. The second one is its stability. In the about three years that we've had it, we've had component failures, but we never had a service interruption or any data loss. The third one, which is really critical, is that it is super easy to use in terms of provisioning, storage, and managing the arrays. I'm able to maintain a multi-site environment with a couple of dozen arrays with a single mid-level storage admin."
"Their support system has insight into errors on our SAN fabric that we can't see. They've brought attention to and raised awareness for us about things that we couldn't see, when we were experiencing problems."
"The solution is easy to scale. I'm running two environments right now, so I need to scale. I'm running a part technology. I've got an A-side and a B-side."
"The most valuable feature of Pure Storage FlashArray is its high stability level."
"They have really good baked in analytics to show you trends for growth history, so it does help with future planning for data growth."
"The most valuable features are extremely low latency, high IOPS with VMware, inline deduplication and compression."
"It is all-flash. This makes it a lot faster than the rest of what we have, as it is able to drive high I/O loads, which is big for us."
"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"The UI for this solution needs to be improved."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."
"The software layer has to improve."
"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."
"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."
"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."
"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."
"Data reduction is an area that needs improvement. There is a garbage collection service that runs but during that time, system utilization increases."
"It took us a year to get it to stabilize and to get the best out of Pure."
"The time-to-market could be better at times, but I think that's true for all vendors of hardware."
"The data reduction that we had initially anticipated when we bought Pure and we move over, is way lower than the expected reduction. It depends on the workloads, of course. But that has been a challenge at times."
"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."
"In the next release of the solution I would like to see Vormetric native block encryption."
"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."
"In the next version of this program, I would like to see increased security, higher encryption, and faster throughput."
