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."The solution has probably reduced my power use substantially."
"This is the best all-flash storage array on the market."
"The product cheaper compared to other solutions concerning the technology that they are using."
"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 most valuable feature is its upgradeability."
"The reliability is very good."
"Performance, dedupe, and that it works well with database workloads are its most valuable features."
"As soon as we introduced our first Pure Storage FlashArray, the first benefit was at least twice the performance increase. Our production databases simply ran twice as fast with no other change."
"The in-line dedupe, and the compaction saves us a lot of space because most of our AFFs house VMware VMDK files."
"We recently started using the volume encryption feature, which is helpful because there are some federal projects that require data at rest to be encrypted."
"NetApp tech support is so good. Their tech support has always been so stable and the people are so good in case of any failure or any good feature that needs to be updated or features that supposedly can help with performance to improve some performance. NetApp support is one of the best that I deal with."
"It's very stable. It's always there when we need it. With the Dual Controller, if one drops out, the other one comes right online. We don't use any iSCSI so there is a little bit of a latency break but, over the NFS, we don't notice that switch-on. We can do maintenance in the middle of the day, literally rip a whole controller out of the chassis, and do what we need to do with it."
"The most valuable features of this solution are the deduplication and the ability to move data to different clouds."
"The business copy solution has become faster using SnapMirror."
"The speed is important; no more problems caused by high latency."
"The most valuable aspect of NetApp AFF is the money it saves our organization."
"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."
"I would like to see them lower the costs."
"It's too early to tell if we've seen a reduction in total cost of ownership. The solution is expensive."
"I would like to get a weekly report of how our storage has been used, and if there is any storage sitting there not being used."
"Most of our upgrades have not been as smooth as they should have been."
"Self-backup is the only feature lacking in this solution."
"What it needs to do is work a little closer with solutions, like VMware, so it understands the particular workloads that are on it. Today, it does not understand the applications which are running against it."
"It goes at about 95 percent, so we have had some performance issues. It is hard to clear them."
"The solution could improve by having a multi-tenant feature."
"To be more competitive in the industry, they can develop deduplication, compression, and smarter features in the same array instead of all-flash."
"We have had trouble with restoring applications, and if there is more support for application-aware backups then that would be great."
"The product has size limitations on fax volume. They have increased from 100 to 300, which is still less than other vendors. Or flex groups are not supported."
"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."
"Its integration could be improved."
"The graphical interface is still heavy and slow. Needs more improvement in this area."
"Migrating from a public cloud to on-prem or on-prem to a cloud can be a bit complicated. They have their own solution, but it should be easy to use."
"I would like them to roll in global monitoring instead of having to buy another product for it."
"The write performance could be improved because it is less than half of the read performance."
"The read/write ratio is an area in the solution with some flaws and needs improvement."
