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 solution is scalable."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"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."
"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."
"What I really like about this program, is that it is easy to use and easy to configurate."
"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."
"Technical support has been helpful and responsive."
"It performed great originally, and when it performed great, it was awesome."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"Data Compression: Up to 80% space reduction in the database"
"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"
"The initial setup is straightforward."
"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."
"The speed of the Pure FlashArray is very, very fast and nothing in the market can compare to it."
"On a scale of one to ten, where ten is the most comfortable pricing, I rate the solution a nine out of ten."
"The initial setup is very straightforward. You simply plug it in and turn it on."
"It's extremely stable and has good performance."
"Pure is simple to set up and manage on a day-to-day basis."
"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 feature is test performance. It helps us store large amounts of data along with providing us faster retrieval of data."
"I never have to worry about its performance or if it is the root cause of an issue."
"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."
"There is room for improvement in the pricing of the product."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"In fututre releases, some focus on anti-malware should be there."
"They could add more support for file storage and different types of storage."
"We need better data deduplication."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."
"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."
"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."
"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's somewhat scalable, but maybe not so much as some of the competition."
"As long as they always improve on IOPS speed, that's all we're really looking for. The faster the storage can be the more we can do speed of application and speed of use."
"It would be nice to have a better view of the allocated capacity on their Platform as a Service solution because we have to do some manual calculations to understand how much we are going to pay every month to use the storage that is allocated."
"It's too early to tell if we've seen a reduction in total cost of ownership. The solution is expensive."
"The way Pure Storage does the controller storage warranty or replacement has been an issue for some people who just replace the controllers every couple of years, and that's where some of the confusion with pricing and support has come in. They should be clear on the way the controller replacements happen, as it is important to know whether or not you can get a good return on them, because it can be a little confusing."
"If we suddenly dump large amounts of data onto the storage system, it takes a while to process it."
"There are a lot of things to improve."
"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."
"The higher education moves slowly. We are still looking forward to implementing the full list of existing features."
