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 comes with a large number of features out-of-the-box, which makes it easy for us to see problems and manage capacity."
"Pure gives us better compression, it's easier to manage, a lot less hands-on."
"The initial setup was very straightforward and very quick. It was up and running in our data center within 24 hours of receiving it."
"My rating of Pure Storage is a ten out of ten because of the price for performance and footprint - the overall value."
"The stability of Pure Storage is very very good."
"It is always out of the box, and ready to use."
"Very stable; no worries about how much it can handle."
"Has also helped simplify storage for us. The other person we put in there, took about a week to implement. And we had both arrays set up within around four hours with a thirty minute drive time between the two locations."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"The initial setup is straightforward."
"It performed great originally, and when it performed great, it was awesome."
"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."
"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."
"We're able to access it from just about anywhere, as long as we have access to a browser. That feature is really neat because sometimes we will go to a different data center or a different site, and if we need to access it to see a LUN or to see any type of storage, we can do that. That's one of the big takeaways with Unity."
"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 most valuable features of Dell Unity XT are the data compression for all of our VMs up to four times and the performance is good."
"The initial setup was very straightforward. Migration was smooth and configuration of the storage was quick and simple. The time needed to put it into production was less than expected, and data migration itself went without a glitch."
"We've never had an issue with storage."
"I like Unity XT's software-defined storage. It's a new feature that isn't widely used yet, but customers are impressed with it."
"The most valuable feature is the performance. It's still an all-flash array at a good price point."
"It is scalable, and we usually recommend Dell Unity XT to small and medium companies."
"Going forward, don't complicate things for the customers."
"The data reduction that we had initially anticipated when we bought Pure and we move over, is way lower than the expected reduction. It depends on the workloads, of course. But that has been a challenge at times."
"The price could be better."
"We would like to see better troubleshooting aspects. It helps us if we can find out where the problem is. Right now, it's difficult. Sometimes it's difficult to pinpoint the issue. If they had more visibility and more troubleshooting feature built into the tool that would really help."
"It would be good to have metrics of the box's performance so we can see what it delivers, but currently, I can't see what it's actually doing."
"I would rate this solution an eight. There's always room for improvement, nobody is perfect to get a ten out of ten. They do what they do well. It's not cheap but we it's for uses that we needed."
"I had to contact customer support when a drive failed as I was doing a couple of OS upgrades."
"The product should improve its response time. I have also encountered issues with its configuration."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"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's somewhat scalable, but maybe not so much as some of the competition."
"Snapshots are not as easy to access as on a NetApp device."
"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."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"The interface can be a little challenging for someone new."
"Dell Unity XT’s price needs improvement."
"Inline dedup compression security is coming up as an issue, encryption, etc. is key for our customers. If we could have more ways to do software-based encryption, those are the features customers are asking us for, as well as replication."
"I would like to see a more seamless virtual box integration with the physical box which can replicate, because the setup of the replication is very difficult right now."
"The interface and configuration could improve."
"Thick provisioning of LUNs."
"We would like to see the concept of Storage Groups brought back to this product line."
"I miss storage groups. Now, if I have to add a LUN to a cluster, multiple host, I have to know which host is in that cluster. I have to write it down and that makes it hard. In VNX and earlier, I could simply put a LUN on a storage group and every host in the group had the LUN. This lack bothers me a lot because it takes a lot of time and mistakes are made. Sometimes, a Hyper-V host gets a VMware LUN and vice-versa. Not good."
