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."The mobile app is very helpful."
"We like the speed. It's very low latency. In virtualization, you can mask lots of problems, and even in code you can mask lots of problems, with low latency. It's just pure speed and low latency."
"It is easy to manage. You don't have to have the same people who used to manage the Dell EMC arrays because the solution is more intuitive."
"The solution offers amazing performance."
"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."
"It allows engineers to focus on other things rather than doing the more manual tasks. It automates tasks, so the ease of use is extreme. It simplifies the storage."
"The most valuable features of Pure Storage FlashArray are simplicity, ease of use, and dashboard management."
"My rating of Pure Storage is a ten out of ten because of the price for performance and footprint - the overall value."
"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"
"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."
"High performance and ease-of-management are the most valuable features."
"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."
"The maintenance service and support from IBM is very good."
"The most valuable features are deduplication and compression, which together, enable you to have more space."
"IBM's technical support do excellent work."
"I like most of the features. Its speed, performance, and availability are valuable. We are implementing the data reduction technology the most."
"The most valuable feature is that is supports a high IOPS rate."
"The GUI is very easy and performance is also good."
"The most valuable features are deduplication and compression."
"The performance is very good and we use this product to enhance our core system."
"We need to add more storage in Pure Storage FlashArray with the cluster mode activated for us to have better performance."
"There are scenarios with very specific functionality around VMware integration particularly to do with the way we'd like to manage LUNs in VMware. The tools are pretty good but there's room for improvement there."
"Areas for improvement would be the financial operations. In the next release, I would like to see a NAS protocol included."
"The higher education moves slowly. We are still looking forward to implementing the full list of existing features."
"The solution is not cheap."
"The credentials on the iSCSI interface are only available to type in with the Chrome browser, and not with the Firefox browser."
"Pure Storage support could be a little better."
"We have not seen a reduction in our TCO nor have we seen ROI."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"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."
"Snapshots are not as easy to access as on a NetApp device."
"It's somewhat scalable, but maybe not so much as some of the competition."
"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."
"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."
"The solution should improve its pricing and the mechanism in the reduction pool."
"The support could improve by allowing you to speak to someone when you call rather than them calling you back. However, once we do have contact with one of their technicians they are excellent."
"I think the only thing the developers can look at, is that it is limited to 25 gigabytes currently. In the next release they might want to increase that."
"IBM could do more marketing and improve brand awareness. I had never heard of this product until a colleague told me about it. FlashSystem could add a few features, but it would probably increase the price. For example, Pure Storage offers instant snapshotting and partitioning. That would be nice to have, but I think the cost would go up."
"The installation is not easy. You need to have extensive knowledge to handle it."
"Include an option to upload the support package to the IBM ECuRep when opening an IBM PMR."
"The only issue my team faced was transferring the data from the old system to IBM FlashSystem, which is an area for improvement in the solution."
"Their technical support needs improvement in terms of reachability for the clients and response times. They should be more responsive and have more online platforms for support. They should make more technical information available online. There could be some kind of documentation community."
