We performed a comparison between Dell PowerStore 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."One of the best features is the support, which is excellent."
"The most valuable feature of this solution is its ease of use."
"The solution is scalable."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."
"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."
"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."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"The solution is stable."
"When compared to Pure Storage, Dell PowerStore's cost was quite attractive."
"A particularly valuable feature is its simplicity."
"The main feature of Dell PowerStore is its support for NVMe as well as hybrid solutions."
"The solution is very easy to implement."
"The most valuable feature of the solution for me is the deduplication part, especially since most of the servers in our organization are Windows-based servers."
"The deduplication functionality provided by the solution is fairly good. The speed offered by the product is enough for our organization."
"The solution's technical support is excellent. I rate the technical support a ten out of ten."
"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."
"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."
"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."
"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 terms of what needs improvement, the dashboard and management could be simplified."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"It is on the expensive side."
"The pricing could be lower. It is very expensive."
"While using Dell PowerStore's interface in our organization, we sometimes miss out on some information."
"I do not like having to use VPLEX for synchronous replication, as opposed to having the store software built-in."
"The NAS part is very poor. It's very basic. Even Dell EMC has said that to us. We are waiting for version 3 of PowerStore for that. This must be improved and it is in the roadmap."
"When it comes to Dell PowerStore, I would like to see more integration and more security features included. It's unfortunate that the solution does not feature Flash trace."
"We would consider this solution if the pricing is competitive with other options, as it offers a very good solution. However, the current price is slightly higher than the competition."
"Horizontal scaling has room for improvement."
"I have not seen anything specific. The only thing I can think of that needs improvement is the price."
"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."
