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."The data reduction technology part of the scalability has been impressive, like its ability to host additional workloads, volumes of data, and databases."
"NVMe data storage platform that's easy to set up and easy to use. It's stable, with a lower response time, and quick technical support."
"It's very fast and very easy to use. It performs well and is both flexible and compatible. We like it because it's easy to use."
"I use all the features of this solution and I find them to be easy to use and functional, such as the compression and capacity to expand."
"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."
"My rating of Pure Storage is a ten out of ten because of the price for performance and footprint - the overall value."
"The most valuable features are the replication of data and the continuous snapshot that we can take from the disc."
"The solution offers amazing performance."
"High performance and ease-of-management are the most valuable features."
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"Data Compression: Up to 80% space reduction in the database"
"It performed great originally, and when it performed great, it was awesome."
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"The initial setup is straightforward."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"It is simple to use and easy to manage. We don't touch it after we set it up."
"They have a Unity REST API that I use to automate some of the storage stuff. I'm just getting started with it, but it seems pretty easy to use."
"It is definitely one of the most robust, solid, well-performing products that I have dealt with. It is set it and forget it, which is pretty amazing."
"The performance combined with the gig-per-dollar value is a combination that is superior to other storage options."
"The benefits are the simplicity, flexibility and the ease of integration between the Unity platform and VMware, for example, and Microsoft platforms; the integration tools and the simplicity of management."
"It is a workhorse and will run even demanding workloads."
"It does great deduplication. From a storage perspective, we save money being able to dedupe right on the disk"
"The Snapshot feature is key."
"Historical analytics would be useful. At the moment, they don't have any type of application built for historical analytics."
"Pure Storage FlashArray could improve by being more secure."
"The file functionality could be better."
"As long as they always improve on IOPS speed, that's all we're really looking for. The faster the storage can be the more we can do speed of application and speed of use."
"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."
"As partners, we should have the option to download the software, rather than have to go back through Pure to obtain it."
"Most of our upgrades have not been as smooth as they should have been."
"It is a bit expensive."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"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."
"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."
"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."
"The pre-sales technical support and technical engagement could be made better for this product."
"As the solution continues to grow and gain more traction, things will come up that will just continue to deepen the integration between VMware, vCenter, and all those other components. Anything in the divisibility there and additional tools is always great."
"Stability is the problem. We've had stability issues with it. We've had problems with the iSCSI interface. We've had it for two years now and for two years we've had problems where a service processor will drop, we'll lose connectivity to LUNs, we'll lose connectivity to the storage, issues like that. No matter how we've tried to chase it down, everybody just points fingers at each other. The only thing that changed in our environment was that the Unity solution was installed."
"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."
"Scalability is not good. We have a Unity 300, now we have to do a data-in-place conversion for the next upgrade because only 150 slots are supported, not drives, only slots."
"The biggest one for us, and the reason we don't use it more, is that we can't throttle the replication speed. If it's on, it's on. So we have to be a little more WAN-sensitive, in some applications, which means we can't put it everywhere. That's the biggest issue for us, by far."
"They should update to the cloud."
"The product’s pricing should be improved."
