We performed a comparison between DDN IntelliFlash and NetApp AFF 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."I like its speed. It has all the features that I need."
"The most valuable feature of Pure Storage FlashArray is its high stability level."
"The stability is very good. I've done destructive testing on it and never had any type of storage outages from it."
"We've had to use tech support on a number of occasions. They did everything remotely and talked us all the way through. They fixed the issue within 30 minutes. Every single time we contact them, they're perfect. I would give their technical support a ten out of ten."
"With Pure Storage, we don't see any latency or IOPS. It has been a very seamless integration."
"Its array houses our entire production environment."
"What I like most about this solution, is the speed, resiliency and scalability."
"This solution has helped my organization by cutting down on provisioning time. I used to have to provision a VM and it would take ten minutes. Now, it takes thirty seconds."
"The initial setup is straightforward."
"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."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"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."
"The solution’s thin provisioning has allowed us to add new applications without having to purchase additional storage. We use thin provisioning for everything. We use the deduplication compression functionality for all of our NetApps. If we weren't using thin provisioning, we'd probably have two to times more storage on our floor right now than we do today."
"I would say the consistency with the ONTAP versions and the speed and performance from the flash."
"One of the main features that we love about the system is the ability to create snapshots. NetApp makes a lot of snapshots in a short space of time. Also, the speed of data recovery with NetApp, at the time we need it, is an important feature that we love."
"The initial setup was straightforward."
"We just migrated two petabytes of data storage from IBM over to NetApp All Flash. Some of the performance improvement that we've seen is 100 times I/O and microsecond latency."
"If the AutoSupport is well configured, then you need not to do a monitoring. You will get call and mail when any issue is completed."
"Speed. it's very performance designed. It's designed to have a lot of high speed."
"Setup was simple and easy."
"It would be good to have metrics of the box's performance so we can see what it delivers, but currently, I can't see what it's actually doing."
"The GUI is simplistic and basic. I feel like it's explanatory, but not enough, it needs a little more to it."
"The primary drawback is the cost, which can be prohibitive for small configurations."
"We've had it in place for about a year and a half and have had zero complaints, other than that box-to-box replication is not encrypted."
"As partners, we should have the option to download the software, rather than have to go back through Pure to obtain it."
"The backend of this solution utilizes an Active/Passive architecture, rather than an Active/Active architecture, which is a disadvantage, when compared to some of its competitors. Its storage capacity should be expanded in the next release."
"We do have an issue with the vCenter integration. Pure Storage says it has a lot of free space, but vCenter says its completely full. This is because their dedupes are saved as space, but Vcenter still detects the disk as completely full. So, we do have an issue with that."
"Going forward, don't complicate things for the customers."
"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."
"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."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"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."
"It's somewhat scalable, but maybe not so much as some of the competition."
"A while ago, they performed quite slowly."
"This is an expensive solution that could be cheaper."
"Better stability, not releasing features until they are fully functional, or at least giving us a software train that doesn't add them until they are fully functional and proven."
"I would like to see more frequent updates at a faster pace."
"Cleaning up false positives on alerts. We get a lot of those."
"When it comes to the connectivity on the back end, where the hardware is concerned—the cabling and the like—it could also be simplified to ease the communication between the nodes and between the other components of the infrastructure. I still find that a little bit complicated."
"It has not reduced our data center costs. NetApp charges a pretty penny for their stuff."
"The stability is good but there is room for improvement with other options."
