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, Pure Storage and others in All-Flash Storage."The mobile app is very helpful."
"The most valuable features of Pure Storage FlashArray are management and administration user-friendliness, provisioning, and performance."
"We also like the compactness, the small footprint. It takes up very little space in a data center and uses little power."
"Pure Storage technology allowed us to automate tasks, reducing something which started as a 12-hour turnaround down to about 15 minutes."
"It worked flawlessly."
"The reliability is very good."
"It is an easy to use product for all of my team members."
"It is pretty much just plug and play. There is not that much to do with it. It is very easy to use."
"A particularly valuable feature is its simplicity."
"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 supportability of SCME drives for faster data access from the PowerStore and is the most valuable feature."
"For access from virtual machines, iSCSI, and NFS, it is very good. It helps increase performance."
"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."
"Migrations are very easy and fast."
"This solution is very useful to us as we use it internally for all of the services that we need. We use it as a lab and we showcase new technology to the customers and how it can help them going forward."
"The most valuable features of Dell PowerStore are the support for NVMe and SCM, which provides end-to-end performance and high IOPS, minimizing latency. It is a full-fledged storage solution."
"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."
"There are scenarios with very specific functionality around VMware integration particularly to do with the way we'd like to manage LUNs in VMware. The tools are pretty good but there's room for improvement there."
"I would love for them to have a hyper-converged solution."
"I feel like there is too much automation; the user doesn't have any manual input."
"Pure Storage FlashArray could improve some aspects. There are certain features that are good and there are some features that I see some issues with at the technical level. Those issues are related to replication. They need to resolve those issues, which I have already highlighted to the Pure team. Additionally, there are some issues in the active cluster that could improve."
"In the next version of this program, I would like to see increased security, higher encryption, and faster throughput."
"FlashArray's capacity for forecasting should be improved because it needs to be a bit more current. I think it's bundled with the deduplication and other compression factors. We need more user interfaces for forecasting in this software and more interfaces need to be integrated with this array management tool."
"I want to learn more about command line usage which I have not explored much yet. However, there are many automated solutions for repetitive tasks. I would like to see additional features like performance monitoring, configuring of alerts, and the customization of alert thresholds in the next release."
"They should work on their upgrades, they're not smooth."
"The pricing could be lower. It is very expensive."
"Many customers are looking for a cyber recovery feature included in PowerStore. We would like to see this added in a future release."
"PowerStore's management console could be improved."
"The UI should be a little more user-friendly to manage."
"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 solution's pricing could be better."
"The customer service and support are bad."
"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."
"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."
