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."The simplicity of it. The performance is good, but the simplicity is the best thing. Storage management is quite complex, but Pure Storage is easy to manage."
"Simplicity and reliability are the most valuable feature of Pure Storage FlashArray."
"The stability of Pure Storage is very very good."
"The most valuable feature is how it simplifies the management of the SAN."
"The data reduction technology part of the scalability has been impressive, like its ability to host additional workloads, volumes of data, and databases."
"The solution offers amazing performance."
"We have seen savings in our storage. The speed of deployment has gone from several days to a few minutes. This product has reduced that time into minutes, simplifying storage for us."
"We like the speed. It's very low latency. In virtualization, you can mask lots of problems, and even in code you can mask lots of problems, with low latency. It's just pure speed and low latency."
"The initial setup is straightforward."
"High performance and ease-of-management are the most valuable features."
"It performed great originally, and when it performed great, it was awesome."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"Data Compression: Up to 80% space reduction in the database"
"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."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"The initial setup is pretty straightforward."
"The most valuable feature of this solution is its speed."
"The main advantage of this solution is performance."
"Considering the cost, I find NetApp EF-Series All Flash Arrays to be the best storage available in the market."
"It provides multi-protocol, which is what gives the edge when it comes to big lineage PC workloads."
"I would have to say performance at this point, because the application it is based on is so diverse."
"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 management software is very good."
"It needs to improve its price."
"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."
"I would like to see more detailed reporting on the data. However, it would be nice to know what are the exact VMs usage after deduplication and/or what that VMs actual latency and bandwidth is, outside of VMware."
"In some cases, we get into very in-depth conversations around movement of specific data and, what's more, chunk sizes. The documentation lacked any description or information on that."
"I would rate this solution an eight because we have had outages. The commit times went very high in the database. The whole array went down so our customers were down for around eight hours. This was a very big outage which could have been our fault because we didn't do the upgrade in time."
"If they could make it cheaper, that would be something."
"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."
"The system has dual controllers but does not have a high level of resiliency built-in."
"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."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"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."
"It's somewhat scalable, but maybe not so much as some of the competition."
"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."
"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."
"Things like the FlexClones, SnapVault, SnapMirror, all of that. Some of it's available on the EF series, but we like what we have in the FAS system."
"A little more manageability, a simpler management interface. It's not necessarily that it's way overly complex. It's just that it's not as easy as the FAS series."
"Its pricing should be better. Its price is competitive, but they need to improve the pricing. They have different licensing models, which they need to improve. My expectation was cloud integration, which they have, but it is a different license. Therefore, people cannot enjoy it. If I want to use it, I need to pay extra. There is a cost involved for everything, but it should reach everyone. It is similar to having a Rolls-Royce, but you need to pay extra for the key. If you want the key, you need to pay."
"The pricing could be cheaper and it should have documentation in more languages, specifically, Russian."
"I've observed an issue when creating a new storage solution with NetApp EF-Series All Flash Arrays."
"I’d like to see bigger, faster, better hardware, of course. I think that is the way the hardware is trending anyway; bigger, faster CPU, better software, fewer bugs, all that stuff. T"
"There could be better integration with some of our Cisco products."
"Better integration with other brands is important so we would like to see it easier to integrate."
