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.
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"One of the best features is the support, which is excellent."
"The solution is very straightforward to set up."
"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."
"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."
"Pure has signature security technology, which cannot be deleted, even if you are an administrator."
"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 most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."
"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."
"It performed great originally, and when it performed great, it was awesome."
"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."
"Data Compression: Up to 80% space reduction in the database"
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"Pure Storage is extremely reliable — it's never failed."
"The scalability is good."
"This solution is very scalable."
"The most valuable feature is its speed."
"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."
"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."
"The console is simple to use. It has good performance. It is easy to install, understand, and manage, with a good ratio of deduplication and compression. It is doing its job."
"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."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"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."
"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."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"In the future, I would like to see integration with enterprise backup systems."
"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."
"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."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"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."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"Pure Storage will have issues with positioning in the near future since its a relatively new company. For now, customers need a PoC to trust using the solution, as it can't stand on its brand name alone. They need to improve Pure Storage's marketing."
"It's not so scalable. It's got moderate scaling capabilities right now. The clustering technology needs a bit of work, they need to improve that."
"Data reduction is an area that needs improvement. There is a garbage collection service that runs but during that time, system utilization increases."
"We would like to integrate it more with our backup solutions."
"I would like to see more cloud integration."
"On a couple of occasions, the waiting time for an upgrade has been pretty substantial."
"I would rate this solution an eight because we have had outages. The commit times went very high in the database. The whole array went down so our customers were down for around eight hours. This was a very big outage which could have been our fault because we didn't do the upgrade in time."
"In the configuration, which we brought in or tested it in, it has a very limited config as far as the array goes. That said, it still did more than our anticipation."
