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."The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."
"The most valuable features of this solution are its ease of use and performance."
"The initial setup was extremely simple and straightforward."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"Overall stability is very good. It is a very stable solution."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"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."
"One of the best features is the support, which is excellent."
"The PowerStore's compression ratio is even higher than the Unity system."
"The support is very good."
"Currently, the features of replication and deduplication have been very important to us."
"Migrations are very easy and fast."
"I like the performance of the PowerStore. When you talk about PowerStore, it's mainly about flash systems and high-end IOPS. The 1000T is a midsize box, in terms of the way the vendor positions it, but it is more than enough for our needs."
"The solution is extremely stable."
"It is a stable solution."
"The simplicity and ease of use have been very valuable features. I have a very small team, and only half of the team is well versed in the HP product. Whereas if I bring PowerStore in, everyone can learn it because it will be new on the floor."
"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."
"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."
"In terms of what needs improvement, the dashboard and management could be simplified."
"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"There is room for improvement in the pricing of the product."
"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."
"I'd like to see the product implement active replication for vehicles such as VMware."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"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."
"After the smooth launch of the product in our company, only the areas around upgrades are a bit problematic. In our organization, we face difficulties when updating 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."
"The cost of technical support is high."
"Many customers are looking for a cyber recovery feature included in PowerStore. We would like to see this added in a future release."
"The only thing is that with PowerStore, we don't have a solution for the file object."
"The solution's pricing could be better."
"We are looking for the Dell PowerStore to become more mature to maximize our use cases."
"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."
