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."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"The latency is 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 solution is very straightforward to set up."
"The most valuable feature of this solution is reliability."
"Pure has signature security technology, which cannot be deleted, even if you are an administrator."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"The most valuable features of this solution are the deduplication and the ability to move data to different clouds."
"The most valuable features are deduplication and compression, so we get more out of our storage. The replication is also important."
"I think it is a very stable product."
"Regarding features, SnapMirror is one we depend on right now. It helps us provide snapshots to the customers on request. There are many scenarios in which we might take snapshots in various daily use cases. We trigger the snapshots, which gives us a sense of security because we know we have this technology in place if something happens."
"There are many reports accessing the applications. We receive them very quickly. We used to wait a long time for them. Now, you just need to wait a moment."
"The technical support is fantastic. No one else is like their team. We're happy with them."
"The ease of use for setting up our basic shares such as NFS and CIFS is valuable. It takes a couple of clicks to set up things like object shares."
"The most valuable feature of AFF is that it offers better visibility and control over performance, ensuring it meets customer needs effectively."
"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."
"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"The tool's pricing is higher than competitors."
"The tool's portfolio is minimal. It is expensive."
"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."
"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."
"They could add more support for file storage and different types of storage."
"I would like to see replication and DR features in the next release of this solution."
"In terms of improvement, IO performance could use some enhancement."
"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."
"I come tech support with difficulty because I installed NetApp for many years I know what to expect when I call. When I don't get their support tech that I'm expecting and I'm trying to get to the right one, it can get very frustrating for me personally, trying to all-flash push my way into the right person. NetApp has the right people, it's just a matter of getting to them."
"We have been seeing some challenges around the application layer implementation. We are having some teething problems now with the cooperation between the application layer and backups to things, like SnapCenter. This may be a question of product maturity."
"We would like to have a feature that automatically moves volumes between aggregates, based on the performance. We normally need to do this manually."
"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."
"NetApp could focus even more on the configuration."
"Better stability, not releasing features until they are fully functional, or at least giving us a software train that doesn't add them until they are fully functional and proven."
"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."
