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."It has improved my organization because now have lower latency, we get fewer complaints from customers, and we see a constant response time."
"The solution is very reliable."
"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."
"It helps to simplify storage because it has an easy front-end to access everything."
"It is the SAN backbone for our company."
"Pure Storage is extremely reliable — it's never failed."
"The stability is very good. I've done destructive testing on it and never had any type of storage outages from it."
"The solution is easy to scale. I'm running two environments right now, so I need to scale. I'm running a part technology. I've got an A-side and a B-side."
"All of the features are good. With Flash, we have high-performing databases. Having that kind of performance has been valuable."
"Tech support has been absolutely amazing. I think on the technical aspects as well, my staff is able to get great support from the NetApp technical support resources that we have. What I love about NetApp is they have a health care division. At times, it's such an amazing thing because if we have a healthcare-related issue, there's no one better than having prior CIOs from health care organizations that NetApp has hired, and that are part of the health care team, to help out with any of those initiatives and support problems. Support has been absolutely phenomenal."
"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."
"Speed, reliability, ease of use are the most valuable features."
"We just migrated two petabytes of data storage from IBM over to NetApp All Flash. Some of the performance improvement that we've seen is 100 times I/O and microsecond latency."
"The ease of use, the SnapMirror capabilities, the cloning, and the efficiencies are all good features."
"The most valuable aspect of NetApp AFF is the money it saves our organization."
"Technical support has been okay."
"The implementation of both block and file system storage in a single GUI provides is better situated than most other storages."
"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."
"Integration with VMware"
"The replication feature provides another functionality to protect your data."
"It is very stable even during multiple power failures."
"I really value deduplication and compression to save space."
"The most valuable feature is the tight VMware integration, due to the migration from bare metal to virtualized environments and then on to the cloud."
"We would like to be able to connect to data tape for backup, specifically to the LTO backups."
"It is not possible to create a cluster on top of multiple arrays."
"They are doing some stuff with containers and an object search. These could be improved, because containers is one of the main topics that we are talking with our customers about."
"The price of the solution can improve."
"The product should improve its response time. I have also encountered issues with its configuration."
"Its price needs improvement. Its price is almost double than any other flash storage solution."
"In the next release of the solution I would like to see Vormetric native block encryption."
"The internal garbage collection process has been fixed recently in some OS updates so it is more efficient but that could be just a little better."
"We have had issues with CIFS presentations and outages, so if that was removed, we could do seamless upgrades without affecting CIFS presentations. That would be an advantage. That's about the only improvement I can think of."
"One minor improvement could be making scale-up solutions with AFF more cost-effective compared to scale-out options."
"I think adding more features to make it more cloud enabled will help us with cloud tiering and simplify the whole cloud operations when it's integrating with our on-prem AFF products. That is one area where we would like to see more improvements from NetApp."
"You have a limit in terms of how much you can expand storage. It sounds like a lot. However, over the years, as you grow, it may be smaller than you think."
"NetApp should have a local presence in Pakistan."
"To be more competitive in the industry, they can develop deduplication, compression, and smarter features in the same array instead of all-flash."
"It has not reduced our data center costs. NetApp charges a pretty penny for their stuff."
"To enhance the already excellent administration, one area for potential improvement could be in terms of integration."
"The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."
"The administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."
"Poor connection to FC."
"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."
"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."
"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."
"EMC VNX needs to support bigger SSD and the Next Generation EMC Unity does this."
"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."
