We performed a comparison between NetApp AFF and VNX [EOL] 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 stability and performance are the best things about the solution."
"They are quite responsive and our local team was pretty good."
"One of the features that my customers are really interested in is immutable snapshots. There are immutable snapshots to which your applications can be reverted back if you are hit by some kind of ransomware threat or malicious attack. That's kind of a key deal, and it is one of the selling points I use to point out to my customers the value and the features that Pure Storage brings to the table."
"The most valuable features of Pure Storage FlashArray are management and administration user-friendliness, provisioning, and performance."
"The best feature is consistently lower latency, even when IOPS crank up to over 75K. The product maintains submillisecond response time, which is incredible."
"It simplifies the overall management. We don't have to worry about storage anymore."
"Non-disruptive upgrades: You can upgrade at anytime without worry."
"The reliability is very good."
"It should scale far beyond our needs. I don't think we will ever hit the edge of it."
"Over the past 18 years, it has been extremely easy to upgrade to newer products and technology. We can upgrade as we move along. So, we have been able to keep up with the newest technology with zero downtime."
"This solution has reduced our data center costs because when we went from the 8000 and 3200 series that took us from 20 racks of storage down to two."
"The most valuable features are the ease of administration and configuration, as well as the speed of deployment."
"The ability to do SnapMirror or SnapVault for data resiliency and backup."
"It is a stable solution."
"The Snapshots and just the overall flexibility of the product have been great."
"It impacts customer retention because of its overall ease. When you are running a business, where time is a factor, that is the biggest selling point. Things happen really rapidly, when they happen, and being able to say, "Yeah, we can get this up and running in a day, if you want," or even less time in some cases. Sometimes, that can be what makes or breaks our case."
"The implementation of both block and file system storage in a single GUI provides is better situated than most other storages."
"The most valuable feature is the auto-tiering, which helps in the speed of data access."
"From my point of view, the configuration that I can sell is restricted to the EMC best practices. It is hard to make a mistake in a solution. It means the configuration has good performance and scalability options."
"It is very stable even during multiple power failures."
"The replication feature provides another functionality to protect your data."
"Integration with VMware"
"It is very stable, even during multiple power failures."
"High availability including non-disruptive updates: We cannot afford downtime windows."
"The GUI is simplistic and basic. I feel like it's explanatory, but not enough, it needs a little more to it."
"In the next release, I would like to see file-level encryption."
"The number of Filesystems is limited, which it is not on the EMC VNX."
"We would like more extended historical data to help with some of the capacity planning. This is something that we are asking for all the time. E.g., what was the historical performance of this particular volume? So, we would like more historicals."
"A three wave application or multi wave application synchronization would be an improvement."
"As long as they always improve on IOPS speed, that's all we're really looking for. The faster the storage can be the more we can do speed of application and speed of use."
"The only time that we had problems with it was that there was a bug in the VVol implementation but, outside of that, it has been flawless."
"In the next release of this solution, we would like to see automated copy data management for SQL Server."
"Its technical support could be better."
"It has not reduced our data center costs. NetApp charges a pretty penny for their stuff."
"In terms of improvement, the support could be a little better."
"Another issue is that for smaller customers, NetApp doesn't have enough disk sizes. You begin with a 980-gigabyte disk and the next size is 3.8 terabytes. There aren't any disk sizes in between. Competitors have more choices in disk sizes."
"The Bezels need improvement."
"The user interface should be more user-friendly, and the configuration could be more accessible."
"Stability could be improved."
"There are little things that need improvement. For example, if you are setting up a SnapMirror through the GUI, you are forced to change the destination name of the volume, and we like to keep the volume names the same."
"The management software used for the VNX is Unicenter. While it is an improvement over Navicenter, used in older EMC SANs, it still feels outdated in comparison to other SAN management software."
"It would be very helpful to get an automated report that shows you the size of the checkpoints and get warnings when a checkpoint is reaching either maximum capacity per a file system or hitting the ceiling on the SavVol pool consumption."
"If the VNX had embedded encryption, that would be great."
"There is no easy way to defrag a RAID group. It would be nice to be able to reduce the size of a storage pool if the storage is not needed anymore."
"Intel Xeon processors with under 2 GHz processing speeds could be replaced with more recent ones."
"EMC VNX needs to support bigger SSDs. Next generation EMC Unity will do this."
"There is an easy replication process between distinct data centers via VPLEX and/or RPA. But I hope in the future that EMC/Dell could replicate this with other types of storage."
"Poor connection to FC."
