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 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."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"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."
"The initial setup was extremely simple and straightforward."
"The solution is scalable."
"The latency is good."
"Pure has signature security technology, which cannot be deleted, even if you are an administrator."
"It performed great originally, and when it performed great, it was awesome."
"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."
"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."
"The initial setup is straightforward."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"The most valuable feature is reliability."
"I like most of the features. Its speed, performance, and availability are valuable. We are implementing the data reduction technology the most."
"Installing FlashSystem is very easy. It takes less than half an hour, and I can handle it all myself."
"The initial setup is straightforward and can be done in an hour and a half by one person."
"Data deduplication is one of the most valuable features of this solution."
"The solution allows for easy migrations from previous products or vendors via its embedded storage virtualization function."
"The Flash core models offer amazing performance."
"This solution is really user friendly. It also offers good performance and is highly reliable."
"We need better data deduplication."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"It is on the expensive side."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."
"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."
"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."
"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."
"It's somewhat scalable, but maybe not so much as some of the competition."
"It could be easier to implement."
"The solution is not easy to implement. It takes a lot of time to study the product and it's a little complicated in general."
"This product lacks some of the options we wanted. For example, expansion was difficult and it required a lot of patching to be done."
"Enterprise data storage needs improvement. They should create a feature for data and file storage."
"The deduplication and compression ratio is not very good. It's not reaching a very high ratio."
"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 basic setup can be challenging when it comes to certain IP addresses and the configuration of the IP. You have to go in to different menus to makes changes and ensure it is stable."
"This solution could be improved by offering greater amounts of storage."
