We performed a comparison between Dell XtremIO 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 standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"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."
"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"The most valuable features of this solution are its ease of use and performance."
"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."
"Pure has signature security technology, which cannot be deleted, even if you are an administrator."
"The latency is good."
"We mostly use it for backup, because we cannot measure anything, and we are afraid to use it for surveillance systems. We were planning to use it for mostly for surveillance systems."
"The most valuable features are: complete performance and ease of use."
"The guaranteed sub-millisecond response time for a 4K block."
"XtremIO’s capability to run any workload without much in the way of design considerations makes this very easy to use and size."
"Deduplication and cloning capability"
"A valuable feature of XtremIO is that, in terms of administration, it's simple and manageable."
"The program is very stable."
"It is great for applications like Microsoft Exchange, ERP, SQL and VDI; basically saved the VDI buy-in from users, as now performance was seamless in comparison to a physical PC."
"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."
"It is on the expensive side."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"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."
"In the future, I would like to see integration with enterprise backup systems."
"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."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"The UI for this solution needs to be improved."
"The tool's pricing is higher than competitors."
"We've encountered challenges in integrating other products with Dell Xtremio, as it tends to be more vendor-locked. This means we can't easily explore other solutions that might work alongside Dell."
"In some cases where we don’t need the flexibility of the virtualization layer, we could free up resources on the VPLEX by using the storage replication."
"Dell's technical support could be better."
"XtremIO is coming to its end of life."
"Ease of use is key in the converged and hyper-converged world that requires administrators to have both hypervisor and storage skills."
"The implementation isn't exactly complex, but the solution should have some enhancements in it to make the process more centralized."
"I would like hardware capacity additions to be a little more flexible. The upgrade path for the existing XTremIO units requires you to purchase 2 XBricks at a time and they need to be the same capacity as the existing XBricks."
"One thing that should be improved is the reporting and monitoring tools. It should use real time monitoring for storage, IOPS, latency, etc."
"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."
