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."
"What I really like about this program, is that it is easy to use and easy to configurate."
"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"It has good, reliable, fast storage."
"The most valuable feature of this solution is its ease of use."
"The initial setup was extremely simple and straightforward."
"The latency is good."
"The NVMe flash cache is the most useful feature. It lowers transactional speed even more."
"I'm from Germany, so we have lots of metro clusters. The ability to have two sides that are redundant across hundreds or thousands of kilometers is critical for our customers. We have several hundred customers with metro cluster systems, so that is one of the best features."
"The most valuable features are deduplication and compression, so we get more out of our storage. The replication is also important."
"We are using the AQoS operating system, which allows us to get a lot more out of our AFF systems."
"The most valuable feature, primarily, would be speed. That's why we got it. Storage is costly but it's very, very fast. Very efficient, very fast."
"The performance of NetApp AFF allows our developers and researches to run models and their tests within a single workday instead of spreading out across multiple workdays."
"It has improved performance for our enterprise applications, data analytics, and VMs. These improvements are a result of all-flash, throughput, reliability, compression, etc."
"My favorite part is all-flash solid drives. All of my applications are running on an all-flash array. Before, we used to get too many severity tickets on performance, but as soon as we migrated everything to an all-flash array, our critical applications are at top 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."
"I would like to see replication and DR features in the next release of this solution."
"The software layer has to improve."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"The tool's portfolio is minimal. It is expensive."
"It is on the expensive side."
"They could add more support for file storage and different types of storage."
"I would like to see aggregate level encryption in the next release. This is critical."
"Stability could be improved."
"There are no pNFS with VMware VVOLs."
"On the fiber channel side, there is a limit of sixteen terabytes on each line, and we would like to see this raised because we are having to use some other products."
"Higher communication: I love the professional services and I love everything that everyone's able to offer us, but I find sometimes we're not aware of all the things that NetApp can do."
"The ONTAP S3 implementation is not feature-complete as compared to StorageGRID. We had to move our lakeFS instance from ONTAP S3 based on AFF to StorageGRID."
"It would be very useful if we could do the NFS to CIFS file transfer, but it is not supported at this time."
"I would like for them to develop the ability to detach the fabric pool. Once you've added it to an aggregate it's there for life and it would be nice to disconnect it if we ever had to."
"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.
