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's simple, powerful, and ready to use."
"The performance and the ever-growing maintenance are the most valuable features of this solution."
"It upgrades in place which means we'll be using it well into the future."
"The ease of use. That's what our customers love. They say it's very easy, they don't need special training, they don't need to call us or any other company or integrator to help them do their job. That's the main reason they purchase Pure."
"The initial setup was really straight forward."
"We can store more for a cheaper price as opposed to paying for larger devices and larger rack spaces which get outdated sooner and which we'd have to change every two years.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."
"All our junior partners can administer the storage arrays. It is simple and easy to use. We don't have to dedicate a whole team of full time people to work on it."
"The deduplication in the array combined with its snap technologies allows the product to be remotely/manually controlled or scheduled."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"The initial setup is straightforward."
"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 provides a combination of all the protocols that you need, without losing deduplication and compression."
"High performance and ease-of-management are the most valuable features."
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"It is simple to use and easy to manage. We don't touch it after we set it up."
"It does great deduplication. From a storage perspective, we save money being able to dedupe right on the disk"
"We just started doing a bunch of automation where, if an end-user's home directory or departmental share gets filled, I can set certain things through a Unity API so that if it reaches 95 or 98 percent full, it will automatically expand. Now, instead of our getting a ticket and having to go in and do it manually, it does that for us."
"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."
"Veeam Backup integration: Veeam is the defacto standard for backing up of virtual environments."
"For our customers, it's the simplicity of it. They find it easy to use, along with the added features, the dynamic volumes."
"It is pretty stable. I like the stability, because everything works like it should. We made it all redundant. So, we don't have anything to worry about."
"Replication of the communication object (COB) scenarios"
"Most of our upgrades have not been as smooth as they should have been."
"It's not so scalable. It's got moderate scaling capabilities right now. The clustering technology needs a bit of work, they need to improve that."
"Just some nit picky stuff, like allowing servers and volumes to be grouped. Therefore, it would easier to work with them in the GUI."
"What it needs to do is work a little closer with solutions, like VMware, so it understands the particular workloads that are on it. Today, it does not understand the applications which are running against it."
"The scalability of the solution is not as good as it probably could be."
"Part of our company works on Dell EMC because Pure Storage did not have synchronous applications when we were purchasing our products."
"It is way in excess of what we need. If anything, we could see a bit more speed. I'm just comparing it with what some of my colleagues who are implementing their own systems do."
"I can't see where they can make anything better, unless, of course, they lower their prices even more."
"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."
"Snapshots are not as easy to access as on a NetApp device."
"It's somewhat scalable, but maybe not so much as some of the competition."
"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."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"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."
"VNX used to have some features that Unity still doesn't have. From that perspective, the progress is not that advanced."
"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."
"Scalability of this solution could be improved."
"Support Responsiveness & time to fix bugs should be improved."
"Software updates have to be downloaded to the root of the device. This pushes the available space to 95% utilization."
"I would like the UI to look better."
"Recently, they released products, sometimes without proper testing, it seems."
"The only issue is with the product's scalability because it's not as scalable as the other polished tools in the market."
