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."Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"Technical support has been helpful and responsive."
"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 latency is good."
"It has benefited my organization because it has reduced time to insights."
"The most valuable feature of this solution is reliability."
"The most valuable feature of this solution is its ease of use."
"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."
"The supportability of SCME drives for faster data access from the PowerStore and is the most valuable feature."
"I find all of the Dell PowerStore features to be valuable."
"The solution is stable."
"It has its own file formatting protocol, which saves a lot of space."
"There is no complicated configuration for queries and calls. You just create a model and go."
"Its flexibility is valuable because we have had some moments where we had to adapt, and it has been quite flexible."
"The product's initial setup phase was very easy."
"Gives us flexibility, performance, and ease of use. It also has some very good compression capabilities. We were looking for a solution that was easy to install in our VMware environment, that was flexible. PowerStore X is a type of a VMware cluster that you install inside your environment. If you have a VMware environment, like we have in production, it's easy to install and use."
"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."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"They could add more support for file storage and different types of storage."
"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."
"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."
"In the future, I would like to see integration with enterprise backup systems."
"It is on the expensive side."
"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"The UI should be a little more user-friendly to manage."
"I would like to see a Snapshot feature. Currently, it is unable to occupy the capacity."
"While using Dell PowerStore's interface in our organization, we sometimes miss out on some information."
"Reporting is an area that could be improved. It's very simplistic sometimes, and some of the very technical guys on my team want to see more of the details and be able to massage the report a little bit better."
"The support is not very good."
"Could be improved by including a synchronizing feature for the file systems."
"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."
"It doesn't support SSD or Flash."
"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."
