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 this solution are its ease of use and performance."
"Technical support has been helpful and responsive."
"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."
"One of the best features is the support, which is excellent."
"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 initial setup was extremely simple and straightforward."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"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 initial setup was straightforward."
"The most valuable feature is that it is easy to use this frame. I am a SAN administrator, but I was able to train my colleague, who had only been a VMware administrator, on the PowerStore in about half a day. Now he's autonomous in assigning volumes and creating data stores..."
"The main feature of Dell PowerStore is its support for NVMe as well as hybrid solutions."
"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."
"The solution is easy to use and has good performance."
"Typically, high-performance and high-availability features, such as application snapshots and remote and local replication, are highly valued."
"The support is very good."
"There is no complicated configuration for queries and calls. You just create a model and go."
"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."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"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."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"It is on the expensive side."
"The tool's portfolio is minimal. It is expensive."
"The UI for this solution needs to be improved."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"Could be improved by including a synchronizing feature for the file systems."
"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."
"The support is not very good."
"You cannot delegate permissions."
"It needs more mature code."
"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."
"It doesn't support SSD or Flash."
"Many customers are looking for a cyber recovery feature included in PowerStore. We would like to see this added in a future release."
"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."
