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 solution is very straightforward to set up."
"The latency is good."
"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."
"It has good, reliable, fast storage."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"Technical support has been helpful and responsive."
"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."
"Overall stability is very good. It is a very stable solution."
"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."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"High performance and ease-of-management are the most valuable features."
"Data Compression: Up to 80% space reduction in the database"
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"IBM FlashSystem is flexible, quick, and has a solid design."
"When it comes to the interface of the solution we did not encounter any challenges. Additionally, the solution has good documentation."
"The installation is nice and easy."
"At the FlashSystem level, customers are especially fond of multi-tier and distributed rate systems, particularly the dynamic rate six arrays."
"The maintenance service and support from IBM is very good."
"The performance of IBM FlashSystem is very good. The new technology and high throughput have given us more confidence in the solution. The management of the system has improved and we can control the monitoring system alerts and multiple FlashSystems with the Enterprise Cloud Edition, which is free. The migration of recently stored data to a new flash is much easier. You can move your data because you can utilize it externally."
"The most valuable features are deduplication and compression, which together, enable you to have more space."
"Over the years, it has become increasingly user-friendly."
"The tool's pricing is higher than competitors."
"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."
"There is room for improvement in the pricing of the product."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"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 want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"I'd like to see the product implement active replication for vehicles such as VMware."
"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."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"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."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"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."
"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."
"The pricing needs to be more competitive."
"We had issues when attempting to do a flash, we hope to resolve it soon."
"Replication features need improvement. Currently, they are there in the product, but I'm not sure as to how it works exactly."
"IBM FlashSystems is lagging in optimizing storage technologies."
"In the next release having the next level of high-speed performance would be great."
"This solution needs a management console where we are alerted to issues and can report them, or escalate them through email or another method."
"Product support is restricted to IBM only. It must be decentralized to IBM partners as well."
"The generic functionality of IBM FlashSystem, IBM always dismisses using file share or sharing protocols inside their storage hardware, and they only focus on the block-level storage."
