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."The availability and ease of use are the big features."
"The performance of the storage is just unbelievable."
"It worked flawlessly."
"It is fast and reliable. It works."
"It has been very stable. I have not seen or heard of downtime storage issues after moving over to it."
"Support has been helpful."
"The most valuable feature is test performance. It helps us store large amounts of data along with providing us faster retrieval of data."
"It is the SAN backbone for our company."
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"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 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 initial setup is straightforward."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"NetApp AFF is based on Unix, which makes it secure."
"I think that the DR applications are the most valuable, including Snapshots and SnapMirror."
"The in-line dedupe, and the compaction saves us a lot of space because most of our AFFs house VMware VMDK files."
"The most valuable feature of the solution is data protection and snapshot technology for backup."
"This solution makes everything a lot faster. The time to move data around, boot and migrate VMs is much faster."
"Easier to manage with the clustered system and everything with the newest ONTAP 9."
"Organizations can reduce data storage footprint and lower power and cooling costs, helping to adopt "Green IT.""
"We are spending less time putting out fires, so there's a tangible benefit right there."
"The credentials on the iSCSI interface are only available to type in with the Chrome browser, and not with the Firefox browser."
"The internal garbage collection process has been fixed recently in some OS updates so it is more efficient but that could be just a little better."
"The connectivity needs improvement. You do not have the possibility to have a file and block connectivity at the same time on the same machine. It has limited ability to do so."
"They could improve the price."
"I would like to see active replication. I know that it's available now but I haven't tried it yet. I hope that it works."
"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."
"The one major gripe I have is that there is no snapshotting enabled by default on the SAN."
"Some services could be inserted directly into the SAN, so Pure Storage could complete with the HyperFlex."
"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."
"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'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."
"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."
"In the past, NetApp designed it so that you have a 70% threshold. You would never fill up past 70% since you need to have that room available. Whereas with Pure, I can fill it up to 110% of what they listed and it's still going at full speed. NetApp can't do that."
"We would like to have more behavioral reporting."
"The admin tools and the integration with other products and clouds can be improved. It should also be easier to identify and troubleshoot problems in this solution. It takes a long time, and it should be improved."
"When it comes to the cloud, they might need to improve in terms of making it clear why someone would use a NetApp solution over cloud-made storage."
"There are some bugs with the solution which need to be fixed."
"In terms of improvement, IO performance could use some enhancement."
"A graphical user interface displaying efficiency metrics, such as compression and deduplication rates, would be a great addition."
"The certification classes are good, but they don't cover enough of the material, and the exams only test on what is covered in class."
