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 has benefited my organization because it has reduced time to insights."
"Overall stability is very good. It is a very stable solution."
"Technical support has been helpful and responsive."
"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."
"The most valuable features of this solution are its ease of use and performance."
"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."
"The high availability of the product is the most valuable feature."
"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."
"High performance and ease-of-management are the most valuable features."
"Data Compression: Up to 80% space reduction in the database"
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"It performed great originally, and when it performed great, it was awesome."
"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 has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"The most valuable features are its performance and simplicity."
"We just recently started using the Dynamic Pools, so while it's scalable, we actually find it valuable that we can just pop in one or two drives when we need to, instead of having to add a whole RAID set. That has actually been very handy for us."
"The ease of management and “user-friendly” management environment (GUI)."
"Unified block and file storage without the need of control stations and data movers. This simplifies administration and deployment and requires less rack space."
"We like the way it integrates with our environment. These features help us use multiple soft applications. The new features of going off the grid and replicating really help us. They give us an advantage versus traditional storage resources."
"It can be simple to deploy, the standup time is quite quick. The interface is quite quick. The terms are simple, intuitive, it's similar what was there in the VNXE before it. It's very simple to navigate and administer from the console."
"It is lightning fast, low on power and heat, and has a small footprint with great performance."
"All-flash is a game changer. If you need performance, simple operations, and you plan to use it with VMware, it is a good choice."
"The tool's pricing is higher than competitors."
"I'd like to see the product implement active replication for vehicles such as VMware."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."
"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."
"It is on the expensive side."
"The software layer has to improve."
"There is room for improvement in the pricing of the product."
"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."
"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."
"Snapshots are not as easy to access as on a NetApp device."
"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."
"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."
"Scalability for the 650F is good, but I was expecting a little bit more."
"Dell EMC's competitor has a clustering technology. In the next release, it would be nice if they could build that into the product."
"The iSCSI and the VMware integation using vSphere could be less confusing."
"I would like to have secure mobile connectivity going forward. This would help me be more proactive."
"What I'd like to see is a little more detail on the networking side. I can go into where it's showing me the replication, but when I go into the network it just gives me broad-based information. I don't know which replication job is actually feeding it. I have to go in and rely on other apps."
"We integrated it with vSphere but that integration was "iffy". It was okay but we had a few challenges with it."
"It could always use native replication. Then I could get rid of RecoverPoint."
"We would like to see more advanced integration capability added to this solution."
