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."It is an easy to use product for all of my team members."
"The ease of management is one of the most valuable features of this solution. I would have also said that it's pretty fast but now our SQL servers are starting to beat it up pretty bad."
"The most valuable feature of this solution is the support."
"The initial setup was very straightforward and very quick. It was up and running in our data center within 24 hours of receiving it."
"They are quite responsive and our local team was pretty good."
"It is always out of the box, and ready to use."
"The stability is very good. I've done destructive testing on it and never had any type of storage outages from it."
"The most valuable feature is its data reduction."
"I think it is a very stable product."
"Speed. it's very performance designed. It's designed to have a lot of high speed."
"I think that the DR applications are the most valuable, including Snapshots and SnapMirror."
"The initial setup is very simple."
"The newest version of ONTAP has a bit of a learning curve because you need to learn where things are to find them. It is not impossible, but when you are accustomed to the older version of ONTAP, it just takes a bit getting used to it, but it is about the same as before."
"Things that have been really useful, of course, are the clustering features and being able to stay online during failovers and code upgrades; and just being able to seamlessly do all sorts of movement of data without having to disrupt end-users' ability to get to those files. And we can take advantage of new shelves, new hardware, upgrade in place. It's kind of magic when it comes to doing those sorts of things."
"The most valuable features are deduplication and compression, so we get more out of our storage. The replication is also important."
"Technical support is good."
"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."
"We do have an issue with the vCenter integration. Pure Storage says it has a lot of free space, but vCenter says its completely full. This is because their dedupes are saved as space, but Vcenter still detects the disk as completely full. So, we do have an issue with that."
"Most of our upgrades have not been as smooth as they should have been."
"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."
"They should work on their upgrades, they're not smooth."
"It goes at about 95 percent, so we have had some performance issues. It is hard to clear them."
"On a couple of occasions, the waiting time for an upgrade has been pretty substantial."
"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."
"Historical analytics would be useful. At the moment, they don't have any type of application built for historical analytics."
"It can get a little expensive if you need to add more disks. The cost is a pain point for us, especially in terms of expansion."
"There are no pNFS with VMware VVOLs."
"I would like there to be a way to break out the 40 gig ports on them. We have a lot of 10 gigs in our environment. It is a big challenge breaking out the 40 gig coming out of the filer. It would be nice to have good old 10 gig ports again, or a card that has just 10 gig ports on it."
"NetApp should offer more training so everyone can learn about the products. Other vendors have a lot of training options. It would be great if NetApp would highlight how to use the features more so that every admin or person can gain more knowledge about this technology."
"I would like to see the ability to include more applications from applications to managed storage. If we can have more applications or more interface in more applications, that would be great."
"The only downside to NetApp AFF is its price."
"This is an expensive solution that could be cheaper."
"Its technical support could be 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."
