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 all-flash disc is the most valuable feature of this solution."
"It's simple, powerful, and ready to use."
"Most of the problems that we had in the past with the performance in IOPS have disappeared. It has been a great improvement for our customers' services."
"The solution helps to simplify storage."
"The stability is perfect. The reliability is 100% and the latency is always lower than 1 millisecond."
"The code upgrades are very smooth."
"It gives us capacity planning."
"We were actually able to do multiple upgrades, including head upgrades and moving between the platforms, M20 and M50, over the years. We have never once lost a ping and have never had an outage due to an OS upgrade or a complete head upgrade."
"One of the main features that differentiate AFF from the FAS products, or some other technologies used, is the footprint of these arrays are significantly smaller than the traditional ones. Also, the performance that you get to these new arrays is really significant. You can see a huge difference there. By switching to it, we can achieve more storage performance and efficiency as well as in the long run lower down some of the TCOs due to reducing the footprint."
"The most valuable feature is the ease of management."
"The most valuable features are high performance and encryption. It also provides aggregate level dedupe."
"The speed is great. That's probably number one in terms of features we appreciate."
"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."
"I think that the DR applications are the most valuable, including Snapshots and SnapMirror."
"Technical support is good."
"NetApp is like a one-point central management. For example, one can put everything on the right version and control the whole environment from one software solution."
"High availability including non-disruptive updates: We cannot afford downtime windows."
"One of the best features of the VNX is the ability to combine drives of different types into a virtual Storage Pool. By combining small but fast flash drives, SAS drives, and high-capacity but slower NL-SAS drives, the VNX can intelligently move data to the different tiers of storage based on usage."
"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."
"Multi-tiering, positively affects the efficiency of the storage space."
"Good performance for VM environments"
"The implementation of both block and file system storage in a single GUI provides is better situated than most other storages."
"The replication feature provides another functionality to protect your data."
"It is very stable even during multiple power failures."
"The one major gripe I have is that there is no snapshotting enabled by default on the SAN."
"The price of the solution can improve."
"I would like to see more cloud integration."
"If we suddenly dump large amounts of data onto the storage system, it takes a while to process it."
"The number of Filesystems is limited, which it is not on the EMC VNX."
"I would like to see them lower the costs."
"Its price needs improvement. Its price is almost double than any other flash storage solution."
"The scalability of the solution is not as good as it probably could be."
"We only had a few upgrade issues."
"This is an expensive solution that could be cheaper."
"There are some bugs with the solution which need to be fixed."
"In terms of improvement, IO performance could use some enhancement."
"The admin tools and the integration with other products and clouds can be improved. It should also be easier to identify and troubleshoot problems in this solution. It takes a long time, and it should be improved."
"I would like to see more frequent updates at a faster pace."
"The stability is good but there is room for improvement with other options."
"A while ago, they performed quite slowly."
"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."
"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."
"VNX can improve by offering flexible upgrade options. It's not possible to add a single HDD to a current array and there are fixed rules to make upgrades."
"If the VNX had embedded encryption, that would be great."
"Based on our workloads, we see repeatedly in performance reports that the built-in controller (SP) cache of our VNX model is not sufficiently large, resulting in forced cache flushing."
"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."
"Poor connection to FC."
"EMC VNX needs to support bigger SSD and the Next Generation EMC Unity does this."
