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."Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"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."
"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."
"The most valuable features of this solution are its ease of use and performance."
"The latency is good."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"The solution is scalable."
"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 have never had a failure. We can upgrade as we move along with zero downtime."
"MetroCluster provides business continuity and is a critical part of our contingency setup."
"The file-based protocol supports NFS and CIFS."
"The biggest benefit of NetApp AFF is the performance."
"Switching to AFF has improved the performance of a lot of our virtual machines in a VMware environment. The number of support tickets that we receive has fallen to almost zero because of this, so it's been a real help for our virtual server support team."
"I think that the DR applications are the most valuable, including Snapshots and SnapMirror."
"The in-line dedupe, and the compaction saves us a lot of space because most of our AFFs house VMware VMDK files."
"Speed. it's very performance designed. It's designed to have a lot of high speed."
"This has been one of the most reliable storage systems that I have ever used."
"The solution is useful for machine learning and scientific applications, including computer simulations."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"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."
"I would like to see replication and DR features in the next release of this solution."
"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."
"They could add more support for file storage and different types of storage."
"The software layer has to improve."
"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."
"There is room for improvement with the user interface. There are a few things that cannot be done in the GUI. We do a lot of things through the CLI, but that's grown out of a lack of ability to do them in the GUI. An example is QTrees. You can manage them within the GUI, but the GUI is missing a few options."
"In the current atmosphere, private cloud is improving. NetApp AFF needs to provide flexibility in terms of hardware and capital expense."
"A lot of the tools that are built into the stock, ONTAP operating system, instead of having to buy the add-ons and things."
"The only downside to NetApp AFF is its price."
"In terms of what needs improvement, I would like to see more consistency with the UI. It seems to change every few versions. The menus can be in a completely different place."
"I would like to see if they could move the virtual storage machines. They have integrated a DR, so you can back to your DR, but there's no automated way to failover and failback. It's all manual. I'd like to see it all automated."
"The upgrade process could be a lot quicker, but it's still good as it is. The failovers and things like that are harder than expected."
"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."
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.
