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."I never have to worry about its performance or if it is the root cause of an issue."
"It's extremely stable and has good performance."
"The solution has probably reduced my power use substantially."
"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 easy to manage. You don't have to have the same people who used to manage the Dell EMC arrays because the solution is more intuitive."
"The predictive performance analytics is a very good feature, as our system is performing better than before."
"Performance, deduplication, compression, and fast response time for requests from servers and applications."
"We can store more for a cheaper price as opposed to paying for larger devices and larger rack spaces which get outdated sooner and which we'd have to change every two years. It simplifies storage for us."
"The NAS capability is mainly what we're looking for from this product, and being able to recover fast in DR."
"The solution overall has high performance."
"The most valuable feature is the fast cache with functionality rewrite."
"I don't think I've ever seen latencies above 10 milliseconds unless it was something that wasn't the array that was messing up. The thing is rock-solid."
"It is easy to scale, maintain, and manage."
"We have resolved IT challenges with this solution. It sped up our environment. We went from spinning disk to all-flash, which reduced our footprint."
"I have had no problem at all. I think this is one of the most important things. It is very good. Maintaining it and deploying updates require very low maintenance. We haven't had problems. We had to replace a couple of disks in all these years, but it was pretty straightforward."
"The high availability of Dell EMC Unity XT has been the most important feature."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"The solution is scalable."
"Overall stability is very good. It is a very stable solution."
"The most valuable feature of this solution is its ease of use."
"One of the best features is the support, which is excellent."
"Technical support has been helpful and responsive."
"The most valuable feature of this solution is reliability."
"What I really like about this program, is that it is easy to use and easy to configurate."
"There are scenarios with very specific functionality around VMware integration particularly to do with the way we'd like to manage LUNs in VMware. The tools are pretty good but there's room for improvement there."
"I would like to see the NAS add-on component become more fault-tolerant than just a single virtual machine running inside the array. I'm unwilling to use it for that reason."
"We have not seen a reduction in our TCO nor have we seen ROI."
"The only time that we had problems with it was that there was a bug in the VVol implementation but, outside of that, it has been flawless."
"I would like to get a weekly report of how our storage has been used, and if there is any storage sitting there not being used."
"It goes at about 95 percent, so we have had some performance issues. It is hard to clear them."
"This product has only two active controllers, whereas other solutions can have more. This is something that needs to improve."
"I would like to see some improvements on the FlashBlade side around the CIFS space support. I am not super familiar with all the different NAS protocols that they run on their box, but there could be some improvements made on SMB CIFS side."
"Issues with slow responses from the support team."
"I would like to see them add Storage Groups, like we have had in Clariions and VNXs."
"It needs more functionality and the ability to move across more landscapes."
"Perhaps if they added more 10GB ports to the back of the system, so you have more IOPS out of the box itself to the network, that would help."
"I would like better integration with RecoverPoint. My major issue with the solution, all around, has been RecoverPoint more than Unity. While I like the easy user interface, I would like some more advanced features for troubleshooting built into the product, so that we can do more in-depth problem-solving."
"The reporting should be better. In other systems, you can create many different kinds of reports but this is not the case with Dell."
"It could be a little easier to attach it to a network file system."
"Last (and I understand that it has a low chance of being implemented) the copy services currently are redirect on write. It would be great if the administrator could choose between redirect on write and copy on write, when configuring copy job."
"The UI for this solution needs to be improved."
"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."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"There is room for improvement in the pricing of the product."
"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."
"In the future, I would like to see integration with enterprise backup systems."
"The software layer has to improve."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
