We performed a comparison between NetApp AFF and VAST Data 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."Very efficient storage"
"Our storage phones home. It is smart and intelligent in that aspect, which has been huge for us. We don't have to be storage administrators."
"It's extremely stable and has good performance."
"The performance and the ever-growing maintenance are the most valuable features of this solution."
"On a scale of one to ten, where ten is the most comfortable pricing, I rate the solution a nine out of ten."
"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."
"We like the data reduction rates. That has been really helpful. You get 4U of Pure storage replacing something like two racks of spinning disks. One of the things that has contributed to that are the data reduction rates."
"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."
"The features that I found most valuable are SnapMirror and SnapVault; these provide DR and backup for data redundancy."
"The most valuable feature of NetApp AFF for us is its ability to manage multiple IP spaces for our customers in a shared environment."
"NetApp AFF has helped to simplify our clients' infrastructure while still getting very high performance for their business-critical applications. One of our customers uses the vSAN environment in the release, then they use NFS for their VMware VCF environment and TKG environment. In this case, when they move to NetApp for the TKG and the VM infrastructures, they use AFF for block, CIFS, and NFS. It provides a single storage with NFS, block, and CIFS with deduplication, team provisioning, and compression. Everything is in there, which makes it very good to use."
"MetroCluster provides business continuity and is a critical part of our contingency setup."
"We found AFF systems very competitive in terms of performance, storage efficiency, feature richness, and scalability."
"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 most valuable features are the IO performance that we get, the cluster part, and the increased workload and performance with the SSDs."
"The most valuable features for AFF are the speed, durability, back up, the time, the workloads that we are using currently are much faster than what they used to be. We're getting a lot of different things out of All Flash."
"The solution is useful for machine learning and scientific applications, including computer simulations."
"This has been one of the most reliable storage systems that I have ever used."
"The integration capabilities could be improved."
"Areas for improvement would be the financial operations. In the next release, I would like to see a NAS protocol included."
"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."
"Pricing could be better in comparison to other solutions."
"Pure Storage FlashArray could improve some aspects. There are certain features that are good and there are some features that I see some issues with at the technical level. Those issues are related to replication. They need to resolve those issues, which I have already highlighted to the Pure team. Additionally, there are some issues in the active cluster that could improve."
"Historical analytics would be useful. At the moment, they don't have any type of application built for historical analytics."
"It is way in excess of what we need. If anything, we could see a bit more speed. I'm just comparing it with what some of my colleagues who are implementing their own systems do."
"Going forward, don't complicate things for the customers."
"It would be better if they just improved the performance of the system."
"I would like to see an improvement in the high availability of the NFS and CIFS sharing during upgrade and patching; this would help to avoid downtime."
"NetApp could focus even more on the configuration."
"It used to give us the volume where LANs should be placed when we created a LAN in the older version. However, in the newer version of ONTAP, it does not give where to place the LAN in the volume. So, that liberty has been taken away. If that was there again, it would be very good."
"I would like them to roll in global monitoring instead of having to buy another product for it."
"The system is pretty stable but most of the ONTAP versions are not really stable. There have been multiple bugs in different ONTAP versions."
"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 don't work on the technical side of things, so it's hard for me to highlight areas of improvement, but maybe the price could be a little better."
"The read/write ratio is an area in the solution with some flaws and needs improvement."
"The write performance could be improved because it is less than half of the read performance."
