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."FlashArray has many valuable features. It's very user-friendly and it has high availability, so there is comparatively less downtime. During maintenance, there is no shutdown procedure, so you can directly power off the Array and manage the shutdown process without any data loss, which is a unique feature. Managing replication and data migration is also very easy."
"The stability is very good. I've done destructive testing on it and never had any type of storage outages from it."
"The speed is the most valuable feature of this solution."
"Because of the encryption, we have different storage and the encryption can go over both."
"The deduplication and compression meet all of our system requirements."
"Technical support has been amazing."
"The performance is very good."
"The solution is very reliable."
"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."
"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'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."
"The Flash core models offer amazing performance."
"The solution allows for easy migrations from previous products or vendors via its embedded storage virtualization function."
"The most valuable features are, of course, the virtualization of the storage, the performance, and the compression."
"The initial setup is straightforward and can be done in an hour and a half by one person."
"The technical support for this solution is good. They used to help us when the motherboard of Power Systems broke. Their response times are really fast."
"The initial setup was really straightforward. It was not complex. Deployment took one month, due to the data migration duration."
"The FlashSystem 900 consistently delivers performance below 1ms for read/write. This performance is essential for an effective SVC stretch-cluster configuration across two datacenters, and presenting active-active storage to the customer."
"Installing FlashSystem is very easy. It takes less than half an hour, and I can handle it all myself."
"The support for NFS protocols right out-of-the-box need improvement. I'm used to other storage vendors who have NFS support right out-of-the-box, and Pure Storage doesn't seem to have anything."
"I would like to have support available in Spanish."
"Beyond a certain amount of petabytes, you have to have a separate system. Basically, it's not infinitely scalable."
"The price of the solution can improve."
"The data reduction that we had initially anticipated when we bought Pure and we move over, is way lower than the expected reduction. It depends on the workloads, of course. But that has been a challenge at times."
"It is way in excess of what we need. If anything, we could see a bit more speed. I'm just comparing it with what some of my colleagues who are implementing their own systems do."
"The price of this solution could be improved."
"We have not seen a reduction in our TCO nor have we seen ROI."
"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."
"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."
"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."
"It's somewhat scalable, but maybe not so much as some of the competition."
"One area for improvement is in the GUI, where host clusters are not properly dealt with. With Hypervisor host clusters, all hosts must see the same volumes in the same order. Using the concept of a “host-group” has been around (even with IBM) for many years, so why not with the V7000?"
"The pricing could be improved, but I think it's getting better and better with each version. IBM needs to implement NAS storage again, as this is a big flaw. Dell EMC is very good at this and if you compared them based on NAS storage, Dell EMC would win right away. IBM's solution for NAS storage is very complicated. We don't have a storage box that provides file sharing from itself, we have to put software on it and go through a whole complicated process. It should be simplified."
"Our model does not support compression or deduplication."
"Replication features need improvement. Currently, they are there in the product, but I'm not sure as to how it works exactly."
"The GUI for monitoring performance metrics could provide better visibility. For example, it doesn't let me segregate the IOPS per volume."
"The storage capacity of this solution could be improved."
"It could be easier to implement."
"The pricing needs to be more competitive."
