We performed a comparison between DDN IntelliFlash and NetApp EF-Series All Flash Arrays 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."FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."
"The solution is very straightforward to set up."
"The most valuable feature of this solution is its ease of use."
"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."
"Technical support has been helpful and responsive."
"It has benefited my organization because it has reduced time to insights."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"Overall stability is very good. It is a very stable solution."
"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."
"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 performed great originally, and when it performed great, it was awesome."
"The initial setup is straightforward."
"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."
"I like the performance aspect of EF Series. It basically provides everything that we are looking for as a solution, very low latency and very high performance."
"The management of it is very simple. that is the most valuable feature."
"We use it for our VDI environment, and have not had any complaints with it."
"Some of the valuable features include MetroCluster switchover, in terms of disaster recovery, it is easy to use, and flexible."
"Compared to Dell Unity XT, what I see as an advantage in NetApp EF-Series All Flash Arrays is the fact that it is more scalable...The performance of the product is good."
"The replication and mirroring features are very good."
"The most valuable feature is the ability to set a specific margin of performance to a specific workload."
"The hardware and software of NetApp EF-Series All Flash Arrays are easy for us to use."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."
"In terms of what needs improvement, the dashboard and management could be simplified."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"The software layer has to improve."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"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."
"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."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"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."
"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."
"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."
"Their problems are on the software and the controlling of the storage where they lack segmentation and federation."
"Better integration with other brands is important so we would like to see it easier to integrate."
"The dashboard could be simplified."
"NetApp could improve the speed of the rebuilding rate."
"They could improve overall scalability through performance. Denser capacity, which is doable, it is what the competition is doing."
"As far as the manageability, being able to port between the two and have to do less training in-house from a customer point of view, that would be the part to improve."
"I would like to have the ability to replicate data between All Flash and other NetApp storage systems."
"I've observed an issue when creating a new storage solution with NetApp EF-Series All Flash Arrays."
