We performed a comparison between DDN IntelliFlash and IBM FlashSystem 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 is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"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 high availability of the product is the most valuable feature."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"The latency is good."
"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."
"What I really like about this program, is that it is easy to use and easy to configurate."
"The initial setup is straightforward."
"Data Compression: Up to 80% space reduction in the database"
"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."
"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."
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"High performance and ease-of-management are the most valuable features."
"The initial setup is straightforward and can be done in an hour and a half by one person."
"IBM FlashSystem is the best solution for storage virtualization."
"Data deduplication is one of the most valuable features of this solution."
"The most valuable features are, of course, the virtualization of the storage, the performance, and the compression."
"The performance of the All-Flash System is very good. There is more enhanced performance and data production in the solution, which I appreciate."
"Installing FlashSystem is very easy. It takes less than half an hour, and I can handle it all myself."
"I like most of the features. Its speed, performance, and availability are valuable. We are implementing the data reduction technology the most."
"The all-flash storage has tier replication capabilities."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"The tool's portfolio is minimal. It is expensive."
"In the future, I would like to see integration with enterprise backup systems."
"There is room for improvement in the pricing of the product."
"The UI for this solution needs to be improved."
"The software layer has to improve."
"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."
"I would like to see replication and DR features in the next release of this solution."
"It's somewhat scalable, but maybe not so much as some of the competition."
"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."
"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."
"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."
"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."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"The product needs to improve their scalability."
"The installation is not easy. You need to have extensive knowledge to handle it."
"I would like to have a larger disk. Right now, you can get 57 terabytes in a shelf. Once they get the larger disk and you get larger capacities, it'll be even better."
"If you want to expand, you cannot expand the disc enclosure. You have to buy a total individual node. Sometimes, this is difficult because we are just looking for capacity and not a node."
"The design is a little old-fashioned and could be updated. The rack is very primitive and designed in an older style."
"The storage capacity of this solution could be improved."
"In IBM FlashSystem, data reduction is an area with shortcomings where improvements can be made in the future."
"GUI interface should be enhanced more as there is some issues in copy services."
