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 system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"The most valuable features of this solution are its ease of use and performance."
"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."
"The initial setup was extremely simple and straightforward."
"One of the best features is the support, which is excellent."
"It has good, reliable, fast storage."
"Technical support has been helpful and responsive."
"The initial setup was straightforward."
"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."
"Overall, we're quite happy with the product because we can move the data that is stored on more than 10 of our current storage devices to a single PowerStore."
"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 PowerStore's compression ratio is even higher than the Unity system."
"You can add compute and capacity independently. We have sized the solution based on our current needs, but in the future we can choose to increase capacity if we grow our activity in the market. And if we have more business in our monetary system, we can increase compute. The ability to choose what we increase is a good feature."
"The solution is extremely stable."
"The support is very good."
"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."
"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."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"In the future, I would like to see integration with enterprise backup systems."
"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."
"I would like to see replication and DR features in the next release of this solution."
"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."
"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."
"There is room for improvement in the pricing of the product."
"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."
"With PowerStore, we have to choose between block storage and NAS functionality."
"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."
"The solution's pricing could be better."
"It needs more mature code."
"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."
"It was very new when we first deployed it a year ago. Even the upgrade processes and knowing what to expect, as well as documentation, could be more robust."
"When you create a case on Dell's support website, you don't always get someone who is experienced in the kind of systems you need help with...making it an area where Dell's support team needs to make improvements."
"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."
