We performed a comparison between DDN IntelliFlash and Dell Unity XT based on real PeerSpot user reviews.
Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."It has benefited my organization because it has reduced time to insights."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"The solution is scalable."
"The most valuable feature of this solution is reliability."
"One of the best features is the support, which is excellent."
"Overall stability is very good. It is a very stable solution."
"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's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"High performance and ease-of-management are the most valuable features."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"Data Compression: Up to 80% space reduction in the database"
"The initial setup is straightforward."
"It performed great originally, and when it performed great, it was awesome."
"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."
"We have Dell EMC engineers helping us out and doing some over the shoulder training. They are working with our customer right now doing data migration over to Unities from the legacy Oracle stuff. While they're doing this, they're showing people how the Unities work and the ins and outs of the software interface."
"There are also DR and data protection functions that we found in the new Unity, now that we are stepping up from VNX and other storage appliances, that we've started implementing."
"I have found Dell EMC Unity XT to be stable."
"All-flash performance, Snapshotting capabilities and replication are all valuable features."
"My storage team likes Unity's replication features. Three-site replication is a unique feature that EMC offers us."
"It's easy to handle for administrators and it's a unified system. It's not as complex as Celerra systems or CX4 Clariions to administrate. You can do everything with one GUI."
"It has a very intuitive web console that runs in HTML5 and makes navigation and administration fairly easy."
"It is on the expensive side."
"We need better data deduplication."
"The tool's portfolio is minimal. It is expensive."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"It's somewhat scalable, but maybe not so much as some of the competition."
"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."
"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."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"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."
"Recently, they released products, sometimes without proper testing, it seems."
"There are some features in VNX that I wish were in the Unity. For example, Storage Groups for isolating LANs and hosts. That is a big issue."
"If there's anything Dell EMC could do to get the same performance for a cheaper price, that would be great."
"It would be nice to have been able to easily move off our old VNX system to this system. The process is very manual."
"I would like the UI to look better."
"Unity only does compression. It would be nice if there was a deduplication feature as well. At my previous job, we used XtremIO and that was deduplication and not compression, and I think we got more out of it because the more OSs you have that are the same, the fewer copies it needs to keep of all that data. So, the deduplication would be a nice feature to have."
"Improve the administrative user interface so it is easier to work with. Currently, a simple task, such as removing a host from 100 LUNS, takes a lot of time. If they could improve LUN to host model to be more like the EMC VPLEX, for example, it would be great."
"I have a problem because between the Unity XT and the PowerMax, sometimes we need another product between these two products. There could be better integrated and the capacity of the size could be larger."
