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 initial setup was really straight forward."
"Data reduction and compression. Sub millisecond latency."
"The performance of the storage is just unbelievable."
"Data deduplication features make it easier to manage storage and forecast growth."
"The initial setup was straightforward in the way that it was a database vacuum storage."
"Redundancy and the fault tolerance of the platform are the most impressive."
"Having an intuitive user interface to get things running is great."
"The most valuable feature is its data reduction."
"The initial setup is straightforward."
"Data Compression: Up to 80% space reduction in the database"
"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."
"High performance and ease-of-management are the most valuable features."
"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."
"The business copy solution has become faster using SnapMirror."
"The most important features are the IOPS and the ease of the ONTAP manageability."
"Batch times went from approximately seven hours down to about two and a half. Functionality during the day, such as taking or removing snapshots and cloning instances, is higher than it has ever been."
"The most valuable aspect of NetApp AFF is the money it saves our organization."
"Other manufacturers claim simplicity. In fact, frankly, they do have an advantage in that regard, however, they don't have the functionality. If you were to compare one of those products to NetApp, head to head from a feature perspective, NetApp would wind up in the top 10."
"ActiveIQ is the most valuable feature. It's a central point for me to be able to kick into everything every day. I log in first thing and make sure there are no issues, and it helps me with my day-to-day."
"The most valuable features are the performance and the storage efficiency, due to the compression and deduplication... The efficiency is very important because we can buy fewer disks for more data."
"I'm from Germany, so we have lots of metro clusters. The ability to have two sides that are redundant across hundreds or thousands of kilometers is critical for our customers. We have several hundred customers with metro cluster systems, so that is one of the best features."
"A minor issue that comes to mind is that, every once in a while, a hard drive will go bad."
"The time-to-market could be better at times, but I think that's true for all vendors of hardware."
"The solution is not cheap."
"The initial setup of the product is complex."
"It's not so scalable. It's got moderate scaling capabilities right now. The clustering technology needs a bit of work, they need to improve that."
"I would like to see a Nagios monitoring plugin which watches the health and performance of the system. The only one available just checks volume capacity."
"The product should improve its response time. I have also encountered issues with its configuration."
"When we were doing some tests, we found that there was an I/O freeze when they were switching the controller."
"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."
"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."
"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."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"It's somewhat scalable, but maybe not so much as some of the competition."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"When comparing with Pure for example, with Pure you have no maintenance anymore and with NetApp, you still need maintenance."
"Additional performance, additional data efficiencies, that's what everybody wants right now."
"Stability could be improved."
"I would like to see better tutorials available, beyond the basics, that cover subjects like MetroCluster and automation."
"We were migrating from Data ONTAP 7-Mode to its Cluster-Mode. Therefore, we had to get swing gear, then do the migration from loner gear and back onto our new gear. This was a bit difficult. It took us several months to do multiple migrations."
"ZAPI is kind of difficult to use. You know, it's SOAP-like, it's not really SOAP. I would like to see it more of a REST-based JSON, instead of XML."
"The Bezels need improvement."
"We don't have many issues related to the appliance itself. In terms of the OS, we do get some hiccups here and there."
