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."This solution has improved our organization in the way that we used to see latency but now with this solution we don't. It also has good performance. Latencies have come down for our performance in the SQL databases. We can put a lot more in a lot less in terms of space savings. We also save data center space have good deduplication."
"The top-tier support and reliable storage are the most valuable features of this solution."
"We have tons of capacity on it."
"We like the data reduction rates. That has been really helpful. You get 4U of Pure storage replacing something like two racks of spinning disks. One of the things that has contributed to that are the data reduction rates."
"The performance and the ever-growing maintenance are the most valuable features of this solution."
"The deduplication and compression meet all of our system requirements."
"The amount of data that I have moved to it from legacy storage has enabled us to retire units that are three or four times the physical size."
"Pure Storage FlashArray has significantly improved our data center performance. It handles high workloads efficiently, providing better performance in the environment. With increased storage capacity, it has led to improved overall system performance. The tool's technology is a standout feature. It has helped me reduce storage costs by 15 percent."
"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."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"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"
"The initial setup is straightforward."
"Data Compression: Up to 80% space reduction in the database"
"The most valuable features are deduplication and compression, so we get more out of our storage. The replication is also important."
"Technical support has been okay."
"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."
"The most valuable features are high performance and encryption. It also provides aggregate level dedupe."
"The valuable features are the fabric pool. We are taking our cold data and pumping it straight into an estuary bucket. Also, efficiency. We're getting about two and a half times upwards of data efficiency through compaction, compression, deduplication, and it's size. When we refreshed from two or three racks of spinning discs down into 5U of rack space, it not only saved us a whole heap of costs in our data center environment but also it's nice to be green. The power savings alone equated to be about 50 tons of CO2 a year that we no longer emit. It's a big game changer."
"The scale up version of it is the most valuable feature. You can go to 24 nodes, which is very cool."
"The most valuable feature of this solution is its simplicity. It is easy to use."
"We have had issues before on our infrastructure where 20 to 30 percent of the people would come to us pointing the finger at the storage technology or storage back-end. That is now virtually zero."
"I feel like there is too much automation; the user doesn't have any manual input."
"From a scalability perspective, it is a very small storage solution, so it's not very expandable."
"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."
"This product has only two active controllers, whereas other solutions can have more. This is something that needs to improve."
"One thing I'd like to see in a future release is integration between their main storage array and what they call their FlashBlade product; to be able to snapshot directly from the primary array into multiple different backup copies on FlashBlade."
"We understand that they're thinking about it, but one of the things that would be nice is if they added some basic file-level capabilities to the platform. The idea is that they would run a basic NFS or CIF share from the controllers. FlashBlade is the powerhouse for File and Object storage, but if you don't need all that power, a lightweight file function would make FlashArrays more versatile."
"Having something native in the Pure Storage ecosystem would make it integrated and in one single company, and we wouldn't have to work with multiple organizations."
"I would like to see data tiering to AWS."
"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."
"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."
"It's somewhat scalable, but maybe not so much as some of the competition."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"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."
"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."
"I would like to see if they could move the virtual storage machines. They have integrated a DR, so you can back to your DR, but there's no automated way to failover and failback. It's all manual. I'd like to see it all automated."
"A lot of the tools that are built into the stock, ONTAP operating system, instead of having to buy the add-ons and things."
"Going forward, I would like more performance analytics on it, on the area itself, instead of using some other tool."
"I really don't have anything to ask for in this regard, because we're not really pushing the envelope on any of our use cases. NetApp is really staying out ahead of all of our needs. I believe that there were firmware issues. I think it was just a mismatch of things that were going on. It could have possibly been something in the deployment process that wasn't done exactly right."
"AFF could introduce different subscriptions on the platform."
"A while ago, they performed quite slowly."
"After the three-year prepay, the extended warranty is a little expensive."
