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."We also like the compactness, the small footprint. It takes up very little space in a data center and uses little power."
"This solution has improved our organization in the way that we used to see latency but now with this solution we don't. It also has good performance. Latencies have come down for our performance in the SQL databases. We can put a lot more in a lot less in terms of space savings. We also save data center space have good deduplication."
"The first set up we had was really straight forward and simple."
"The most valuable features are the replication of data and the continuous snapshot that we can take from the disc."
"It is all-flash. This makes it a lot faster than the rest of what we have, as it is able to drive high I/O loads, which is big for us."
"It has made working with storage as easy and simple as it should be."
"Because we were able to afford to go all flash, we don't manage the tiers, we're not moving data up, and we're not waiting for overnight cycles."
"The most valuable feature is how it simplifies the management of the SAN."
"It performed great originally, and when it performed great, it was awesome."
"Data Compression: Up to 80% space reduction in the database"
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"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."
"The initial setup is straightforward."
"The Snapshot feature is key."
"Dell Unity XT is user-friendly and easy to use."
"It has good performance."
"Being all-flash makes everything super-fast. It's also great to manage. That's the easiest part. We also have another SAN, from Pure, and the Unity is easier to manage than the Pure."
"The hardware itself, it differs from Compellent and differs from the VNX before it. It doesn't have a separate file harbor that goes with it, there are no separate NAS heads. It's 2U, you have file and block storage, so you get a quite a lot of services for a small footprint."
"The performance combined with the gig-per-dollar value is a combination that is superior to other storage options."
"Key features are ease of use, ease of management, ease of deployment, and the GUI is very user-friendly."
"It's an all-flash Unity, With that compression feature, it's comparable to a hybrid. That is one thing that we definitely like."
"I would like some form of QoS implemented. As a service provider, it would be beneficial to have it."
"Had some issues with Purity not being entirely compatible with VMware ESXi."
"The integration capabilities could be improved."
"I had to contact customer support when a drive failed as I was doing a couple of OS upgrades."
"Part of our company works on Dell EMC because Pure Storage did not have synchronous applications when we were purchasing our products."
"We do have an issue with the vCenter integration. Pure Storage says it has a lot of free space, but vCenter says its completely full. This is because their dedupes are saved as space, but Vcenter still detects the disk as completely full. So, we do have an issue with that."
"I would like to see them lower the costs."
"With scalability, I have run into a little problem with our last upgrade. There were some undocumented limitations to the number of drives that our controller could run on. So, instead of putting in a new data pack as we had anticipated, we had to keep adding and removing to get up to the capacity that we needed to be. What should have been a one day process (or a few hours) turned into a month and a half process."
"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."
"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."
"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."
"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's somewhat scalable, but maybe not so much as some of the competition."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"Snapshots are not as easy to access as on a NetApp device."
"Its replication technology could be better."
"The one thing that we would look at would be if they were to expand the file level features, just to give us a balance or a tier between it and Isilon options out there, for unstructured data."
"Issues with slow responses from the support team."
"The price of Dell Unity XT could improve."
"The NAS capabilities of Unity - I have to say there are a lot of things I miss. For example, deduplication for hybrid. I have tons of customers with VNX and dedupe. These customers achieve around 50% dedupe efficiency and they mostly use them for archive. If you're talking about 50TB of NAS, which is stored in a 25TB repository, which is very economical, and you can not provide that in a Unity hybrid box, you have problems."
"We cannot connect directly with Dell due to sanctions."
"The initial setup is not so straightforward if you don't have experience with storage arrays."
"We would like an AI feature that would protect the backup and minimize the consumed space so we can maintain the quality of the backup. This would help us minimize our IT cost in terms of the backup procedures."
