We performed a comparison between IBM FlashSystem 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."Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"What I really like about this program, is that it is easy to use and easy to configurate."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"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 most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."
"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."
"The most valuable feature of this solution is reliability."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"IBM's technical support do excellent work."
"I like most of the features. Its speed, performance, and availability are valuable. We are implementing the data reduction technology the most."
"When it comes to the interface of the solution we did not encounter any challenges. Additionally, the solution has good documentation."
"The valuable features for us are the extra add-ons, such as the FIM provisioning, the compression, the disaster recovery capabilities, and the storage pooling functions."
"The most valuable feature in demand is virtualization and its support storage of virtualization features."
"The valuable features are high availability, compression, and a failover mechanism. It's a very highly available storage solution."
"The Flash core models offer amazing performance."
"It's a mature product. It's like a BMW that evolves consistently."
"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."
"I'd like to see the product implement active replication for vehicles such as VMware."
"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."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"They could add more support for file storage and different types of storage."
"The software layer has to improve."
"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 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."
"There could be some extra features added."
"Additional licenses might be added for the fundamental licenses, such as those for copying and flash copies."
"The initial setup is complex."
"A big area for improvement is that the data reduction pool feature is not recommended for use in a production environment because it has stability and performance issues."
"The customer's expectations are what they get on the cloud, they're expecting even in the on-premises deployments, going forward."
"The solution is quite expensive. That's one of the downsides to using it."
"The support could improve by allowing you to speak to someone when you call rather than them calling you back. However, once we do have contact with one of their technicians they are excellent."
"In IBM FlashSystem, data reduction is an area with shortcomings where improvements can be made in the future."
"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."
