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."The latency is good."
"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 Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"Technical support has been helpful and responsive."
"The most valuable feature of this solution is its ease of use."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"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."
"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."
"This solution is highly flexible and offers efficient online compression capabilities."
"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."
"For access from virtual machines, iSCSI, and NFS, it is very good. It helps increase performance."
"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."
"Typically, high-performance and high-availability features, such as application snapshots and remote and local replication, are highly valued."
"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."
"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."
"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."
"The software layer has to improve."
"In the future, I would like to see integration with enterprise backup systems."
"There is room for improvement in the pricing of the product."
"I'd like to see the product implement active replication for vehicles such as VMware."
"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"The tool's pricing is higher than competitors."
"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."
"It's also only supported with a limited amount of switches."
"Could be improved by including a synchronizing feature for the file systems."
"The upgrades themselves are running fine, but after the upgrade is when we have a problem. With the update to 1.4, we had a head crash. They told us, 'This is a known issue. Please upgrade to 2.' We upgraded to 2 and, one week later they told us, 'Yeah, there are some issues in 2.0.0. You can lose data. Please upgrade to 2.0.1.' Overall, they need to make the system stable."
"The storage could be improved. I would like a feature for how to best secure an appliance and the storage since we are connecting the container to the public cloud. I would like them to develop another level of security, making it more secure than from what they have now."
"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."
"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."
"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."
