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."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."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"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."
"Overall stability is very good. It is a very stable solution."
"It has benefited my organization because it has reduced time to insights."
"The high availability of the product is the most valuable feature."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"The most valuable features are deduplication and compression, which together, enable you to have more space."
"The most valuable feature is reliability."
"Virtualization of external storage, while adding cache and speed to the external storage."
"FlashSystem offers proven technology in a compact package."
"The performance monitoring feature is useful as it can report in 15 minute intervals by hour, day, week, month, or by a custom date range."
"The solution is very easy to configure and use."
"The compression and deduplication features are the most valuable."
"The performance of the All-Flash System is very good. There is more enhanced performance and data production in the solution, which I appreciate."
"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."
"In the future, I would like to see integration with enterprise backup systems."
"The tool's pricing is higher than competitors."
"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."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"The software layer has to improve."
"The tool's portfolio is minimal. It is expensive."
"We had issues when attempting to do a flash, we hope to resolve it soon."
"The solution is quite expensive. That's one of the downsides to using it."
"I have looked at a few pages of a report I download and I saw a graph there regarding software-defined vendors. IBM is not in a good position on this graph. I know that they are working very hard on this, to make it much better and to get to a level where it's not only hardware but also software to provide a complete solution."
"The interface of this solution could be improved."
"I would like to have a larger disk. Right now, you can get 57 terabytes in a shelf. Once they get the larger disk and you get larger capacities, it'll be even better."
"They don't offer subscription-based payments."
"The marketing could be improved."
"Customization features must be improved."
"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."
