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 system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"Technical support has been helpful and responsive."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."
"The latency is good."
"Pure has signature security technology, which cannot be deleted, even if you are an administrator."
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"It performed great originally, and when it performed great, it was awesome."
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"The initial setup is straightforward."
"Data Compression: Up to 80% space reduction in the database"
"High performance and ease-of-management are the most valuable features."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"When I have an issue and need technical support, I reach out to them either through chat or by submitting a service request, and the response is good."
"Compared to our old platform, everything is more tightly integrated. I don't have to go to different sections to do something. A lot of it is wizard-driven, so it's an easy to use system."
"The NAS capability is mainly what we're looking for from this product, and being able to recover fast in DR."
"I like its performance and support."
"We have resolved IT challenges with this solution. It sped up our environment. We went from spinning disk to all-flash, which reduced our footprint."
"The most valuable feature is the fast cache with functionality rewrite."
"The most valuable aspects of this solution are its stability, performance, and ease of updating."
"The compression and deduplication that will be coming in version 4.3. With just those features, you're reducing the amount of data and the footprint on the hardware."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"The tool's pricing is higher than competitors."
"They could add more support for file storage and different types of storage."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"Snapshots are not as easy to access as on a NetApp device."
"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."
"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."
"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 only keeps one hour of real-time data without the ability to do deep analysis of each element."
"I would like to see them add Storage Groups, like we have had in Clariions and VNXs."
"In the dashboard there could be notification of duplicate files and the like, so we don't have to rely on Windows to do that."
"The solution can use improvement with the patch cluster like the Synchron and Active replication."
"Software updates have to be downloaded to the root of the device. This pushes the available space to 95% utilization."
"Scalability of this solution could be improved."
"Perhaps if they added more 10GB ports to the back of the system, so you have more IOPS out of the box itself to the network, that would help."
"The iSCSI and the VMware integation using vSphere could be less confusing."
"The pre-sales technical support and technical engagement could be made better for this product."
