We performed a comparison between Dell PowerStore and VAST Data based on real PeerSpot user reviews.
Find out in this report how the two NVMe All-Flash Storage Arrays solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."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."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"Technical support has been helpful and responsive."
"The solution is scalable."
"What I really like about this program, is that it is easy to use and easy to configurate."
"The most valuable features of this solution are its ease of use and performance."
"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."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"The solution is stable."
"The PowerStore's compression ratio is even higher than the Unity system."
"Typically, high-performance and high-availability features, such as application snapshots and remote and local replication, are highly valued."
"It is very easy to use. Access is very friendly. It shows you a lot of important information at the first glance. It has been very easy to use."
"The support is very good."
"The initial setup was straightforward."
"Pricing is very good. It's very competitive against those of all the others that I looked at in the marketplace, such as Hitachi, IBM, HP, and Pure. Dell is right there in the mix as far as providing the best price point as well as meeting the performance requirements that we have."
"The solution is extremely stable."
"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."
"They could add more support for file storage and different types of storage."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"In the future, I would like to see integration with enterprise backup systems."
"We need better data deduplication."
"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."
"The setup process could be improved. We had some issues regarding configuration and the time it took to do things. It wasn't specifically the people we worked with, but more the process and how it's done. They can work on that."
"There are certain shortcomings with the technical support team of Dell PowerStore, where improvements are required."
"Where the system needs to improve is by adding more enterprise features like replication on other sites. We would also like it to be much more aligned with the VMware version. For example, today we have two different versions of VMware ESXi running to keep the PowerStore online. It would be better if the software cycling was faster."
"Horizontal scaling has room for improvement."
"The only thing is that with PowerStore, we don't have a solution for the file object."
"During the installation phase, the licensing part was not straightforward. It was very difficult for the technicians, who are not trained Dell EMC technicians, to do the licensing because the information on their website is not straightforward... Eventually, I had to pass this task to our business partner and they did it for us."
"I would like to see a Snapshot feature. Currently, it is unable to occupy the capacity."
"The only area I can highlight for improvement is that the 4:1 data reduction target has not been reached. This may be due to an issue with Dell EMC's initial analysis of data compression. As a result, we have had to add new physical disks to reach our goal of total available disk space."
"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."
