We performed a comparison between Dell Unity XT and Pure FlashArray X NVMe based on real PeerSpot user reviews.
Find out in this report how the two All-Flash Storage solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."It is an SSD array that has awesome performance, low submillisecond latency, and does what it is supposed to do. It just works, which is difficult for things to do anymore."
"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."
"It is fast and reliable. It works."
"It's simple, powerful, and ready to use."
"The speed is the most valuable feature of this solution."
"The first set up we had was really straight forward and simple."
"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."
"The scalability options are very nice because you can scale it much better and faster. The scalability was there in the previous environment also, but this is far better than what we had before. It basically helps the user in case they are looking for more storage. We can scale it much faster."
"The most valuable feature of Dell Unity XT is the GUI, it is very good. End users can manage using it. Additionally, the documentation is of high quality and it integrates well."
"Unified block and file storage without the need of control stations and data movers. This simplifies administration and deployment and requires less rack space."
"For our customers, it's the simplicity of it. They find it easy to use, along with the added features, the dynamic volumes."
"The inline deduplication and data reduction capabilities have been the most valuable."
"The performance is great. We have four or five different Unity arrays, and they have all run flawlessly."
"The most valuable features are its performance and simplicity."
"I like that when you log in it gives you a dashboard of what your storage looks like."
"Scalability is good."
"The latency is good."
"Technical support has been helpful and responsive."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"It has benefited my organization because it has reduced time to insights."
"The high availability of the product is the most valuable feature."
"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."
"The initial setup was extremely simple and straightforward."
"The most valuable feature of this solution is its ease of use."
"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."
"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."
"We've had it in place for about a year and a half and have had zero complaints, other than that box-to-box replication is not encrypted."
"The price should be lower."
"The number of Filesystems is limited, which it is not on the EMC VNX."
"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."
"I had to contact customer support when a drive failed as I was doing a couple of OS upgrades."
"Beyond a certain amount of petabytes, you have to have a separate system. Basically, it's not infinitely scalable."
"I don't know where the hybrid cloud might be going or what connectivity there is between what was recently released as far as AWS and being able to manage both of them. Maybe there is an on-prem and an AWS instance in the same window, like a single pane, but I would like to see something along those lines, where there wouldn't be two locations to manage storage."
"We had one incident with a memory leak that led to controller reboot. Although it had no impact, when such things happens the storage should be more aware of it, send alerts, and propose corrective actions."
"We would like to see the concept of Storage Groups brought back to this product line."
"VNX used to have some features that Unity still doesn't have. From that perspective, the progress is not that advanced."
"We'd like to see a cheaper version of an all-flash array in that footprint."
"Improve the interface and provide more management capability."
"Licensing has been quite difficult. It doesn't always auto-license. About half the time, when I provision one, I have to contact Service to get a license, or even go to our account manager to help get it straightened out."
"The only challenge I've ever had was with a Drive firmware upgrade."
"I would like to see replication and DR features in the next release of this solution."
"The tool's portfolio is minimal. It is expensive."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"The software layer has to improve."
"We need better data deduplication."
"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."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
