We performed a comparison between Dell XtremIO and VMware vSAN 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."FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."
"The most valuable feature of this solution is reliability."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"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 extremely simple and straightforward."
"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 latency is good."
"The solution is scalable."
"We've seen great enhancements from the performance point of view. There's good availability, stability, and continuity, but the performance actually has increased by 60 or 70%."
"Snapshots are valuable because of their seamless nature, as well as the minimal space each snapshot takes."
"A valuable feature of XtremIO is that, in terms of administration, it's simple and manageable."
"Deduplication and cloning capability"
"The program is very stable."
"Speed and reliability:"
"The guaranteed sub-millisecond response time for a 4K block."
"The most valuable features are: complete performance and ease of use."
"I have used VMware for 15 years and I never had any problems with stability."
"VMware vSAN's most valuable features are the capability to consolidate standalone physical infrastructure into virtualization and the ease of management."
"The technical support is good."
"The most valuable features are productivity and data storage."
"The most valuable features are ease of deployment, and ease of management. If you compare it to other software-defined storage products, it's much easier. It's a checkbox. It's lot easier to manage."
"The solutions best feature is that it is easy to use."
"I like that we could choose whatever hardware we wanted, rather than having to use one particular vendor."
"The most valuable features are its price point and that you can use existing storage; no specific storage requirements are needed."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"The software layer has to improve."
"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 the future, I would like to see integration with enterprise backup systems."
"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."
"We need better data deduplication."
"The tool's portfolio is minimal. It is expensive."
"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."
"This solution is geared toward enterprise-level companies. Small and medium-sized businesses would find it extremely expensive."
"The GUI could be modified more in terms of how the different components are linked to each other."
"Scalability is something that can be improved because there is an issue when it comes to mixing versions."
"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."
"The implementation isn't exactly complex, but the solution should have some enhancements in it to make the process more centralized."
"The product could be improved by reducing the pricing and having better organization in their technical support team."
"It needs a way to determine the deduplication of each LUN and what the impact would be if we were to move data from one LUN to another."
"As a software-based product, it requires a lot of system resources."
"In a future release, they can bring in the object storage capabilities to this solution. Currently, there is not any compatibility."
"There is room for improvement in vSAN's ability to debug. When it's not working well, debugging becomes quite challenging. Identifying issues when it's lagging or not functioning properly can be difficult."
"One of the things that we've had challenges with are when we place hosts into maintenance mode. Sometimes doing so triggers large re-sync processes which can be time-consuming and which have, at times, pushed the capacity to the threshold. I definitely think making some changes in that area would provide some big improvements."
"Improvements are also needed as per the customer's requirements."
"The server files are larger than before."
"It is an expensive solution."
"The only thing I can think of at this time is to improve the performance monitoring and performance visibility within the GUI."
