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 most valuable features of Pure Storage FlashArray are simplicity, ease of use, and dashboard management."
"Having an intuitive user interface to get things running is great."
"The support team is available all the time and they seem to know what they are doing."
"The solution offers amazing performance."
"The stability and performance are the best things about the solution."
"Lone segmentation is simpler and more agile. It's improved the velocity in overall provisioning from project to operation."
"We find the ease of usability and setup valuable."
"The first year, we started out with one or five terabytes and it took what was 20 terabytes of storage down to less than one terabyte."
"Data Compression: Up to 80% space reduction in the database"
"High performance and ease-of-management are the most valuable features."
"The initial setup is straightforward."
"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."
"It performed great originally, and when it performed great, it was awesome."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"In the hybrid version, I would say they are fast. They have fully automated storage tiering. In the all-flash version, higher performance, compression, data replication."
"The most valuable aspects of this solution are its stability, performance, and ease of updating."
"All-flash performance, Snapshotting capabilities and replication are all valuable features."
"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 most valuable feature of Dell Unity XT is its support of protocols for both block, and file levels. It has the features a store solution should have."
"It's very reliable. I have not had an issue with Dell EMC Unity."
"It is ease to use. It performs. It's easy to provision, and It's stable."
"Its quick integration with VMware. The ability to stand up a data store in one place, where you don't have to go and rescan for the data store through the vCenter Client, as well as SMB shares. This ended up being a big selling point for us."
"I would like to see more cloud integration."
"The integration capabilities could be improved."
"The product should improve its response time. I have also encountered issues with its configuration."
"The initial setup was a little complex. We had some initial issues with the design and had to help correct some of the white papers for it, but it wasn't your standard use case."
"I would like to see them lower the costs."
"The initial setup of the product is complex."
"We would like to see more cloud support, which we know is coming, although it's not out yet. It's going to be released in the next versions. That would be the biggest win, if additional cloud support is built into the array."
"Larger capacity and more storage ports would be the two things I'd like to see."
"It's somewhat scalable, but maybe not so much as some of the competition."
"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."
"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."
"Snapshots are not as easy to access as on a NetApp device."
"There is an ESRS problem that we're facing where, for some reason, the other Unity has not been able to register to EMC. The support information is not upgrading and nobody can tell me what is wrong with it. It's a minor issue, the ESRS is still working, but it is something that is very confusing and nobody seems to know what to do about it."
"I think Dell EMC should be more careful in appointing partners, and they need to have better control over their partners. And if their partner has some problems with them, we should not suffer."
"I would like to see them add Storage Groups, like we have had in Clariions and VNXs."
"Things that could be improved include one-to-many replication, data deduplication, and asynchronous Fibre Channel replication. It is asynchronous on iSCSI and I would like to have that on the Fibre Channel. Unisphere-wise, I have to log in to each Unity as a unique environment. In VNX, I logged in to the domain and I was logged in to every VNX. So that's missing."
"We've got massive issues at the moment with IBM AIX. It's not stable. We have a lot of disk errors, production crashes sometimes."
"Dell could improve Unity XT by adding support for NVMe."
"They should update to the cloud."
"We are running VMware, and with the VNXe it was possible to restore. We're using Veeam for VMware backups and with the predecessor, it was possible to mount a backup or restore a backup from a storage snapshot. With the Unity 300, this is not possible."
