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, Hitachi Vantara and others in NVMe All-Flash Storage Arrays."It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."
"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."
"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"What I really like about this program, is that it is easy to use and easy to configurate."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"Technical support has been helpful and responsive."
"Overall stability is very good. It is a very stable solution."
"It's pretty scalable. It can scale up to 24 nodes."
"Our architecture has historically relied on RDMs, so AFF has enabled us to easily migrate from our old EMC PowerMax to the new NetApp. It's been pretty smooth. We have a lot of SAP servers in our environment, so performance is critical for us."
"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."
"AFF works well for VMware storage."
"The tool's most valuable feature is SVM. I also like the speed and response of the filers."
"The valuable features are the fabric pool. We are taking our cold data and pumping it straight into an estuary bucket. Also, efficiency. We're getting about two and a half times upwards of data efficiency through compaction, compression, deduplication, and it's size. When we refreshed from two or three racks of spinning discs down into 5U of rack space, it not only saved us a whole heap of costs in our data center environment but also it's nice to be green. The power savings alone equated to be about 50 tons of CO2 a year that we no longer emit. It's a big game changer."
"Supports file formatting, the main protocols, and the hot swapping of disks and features."
"The most valuable features are the low latency and high-performance."
"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."
"It is on the expensive side."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"The UI for this solution needs to be improved."
"They could add more support for file storage and different types of storage."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."
"We would like to have more behavioral reporting."
"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."
"There is no direct storage attachment available. Most configurations require additional switches for data access."
"Going forward, I would like improvement in the response latencies, capacity size, cache, and controller size."
"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."
"AFF could introduce different subscriptions on the platform."
"A lot of the tools that are built into the stock, ONTAP operating system, instead of having to buy the add-ons and things."
"I really don't have anything to ask for in this regard, because we're not really pushing the envelope on any of our use cases. NetApp is really staying out ahead of all of our needs. I believe that there were firmware issues. I think it was just a mismatch of things that were going on. It could have possibly been something in the deployment process that wasn't done exactly right."
"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."
NetApp AFF is ranked 2nd in NVMe All-Flash Storage Arrays with 281 reviews while VAST Data is ranked 8th in NVMe All-Flash Storage Arrays with 2 reviews. NetApp AFF is rated 9.0, while VAST Data is rated 10.0. The top reviewer of NetApp AFF writes "Since switching, our clients have reported improved performance and reduced latency". On the other hand, the top reviewer of VAST Data writes "Stability-wise, a device that has been up and running for years". NetApp AFF is most compared with Dell PowerStore, Dell Unity XT, Lenovo ThinkSystem DM Series, Pure Storage FlashArray and IBM FlashSystem, whereas VAST Data is most compared with Pure Storage FlashBlade, Pure Storage FlashArray, Qumulo, Dell PowerScale (Isilon) and DDN SFA7990X.
