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."It is an SSD array that has awesome performance, low submillisecond latency, and does what it is supposed to do. It just works, which is difficult for things to do anymore."
"We have seen savings in our storage. The speed of deployment has gone from several days to a few minutes. This product has reduced that time into minutes, simplifying storage for us."
"We're getting good performance, and the compression ratio is also very good in Pure Storage FlashArray."
"Performance, dedupe, and that it works well with database workloads are its most valuable features."
"Pure Storage FlashArray's overall speed is its most valuable feature."
"The most valuable feature of Pure Storage FlashArray is the all-flash storage performance, low latency, and efficiency of their de-duplication technology. Additionally, the ease of use is good compared to other storage systems. The features in data protection, snapshotting, and replication between data centers and sites are superior to other solutions."
"I find two features of Pure Storage most valuable. The first is the "safe mode" function, and the second is its simplicity."
"Lone segmentation is simpler and more agile. It's improved the velocity in overall provisioning from project to operation."
"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%."
"Linear performance – The XtremIO wasn’t the fastest in all tests against other all flash arrays, but even with a massive workload, the response time and user experience were absolutely predictable with no sharp drop-offs."
"Snapshots are valuable because of their seamless nature, as well as the minimal space each snapshot takes."
"XtremIO’s capability to run any workload without much in the way of design considerations makes this very easy to use and size."
"The program is very stable."
"The most valuable features are that it is fast and reliable."
"The solution's most valuable feature is its high performance."
"It has very good performance for an application which needs lower latency and a better response, for example, in microseconds."
"The high availability is very good."
"The feature we have found most valuable is the compatibility of VMware products with VCF and VMware Cloud Foundation."
"The scalability of the solution is most valuable."
"It helped us survive power outages in one of our data centers, then continued to function without a hitch."
"vSAN is one of the easiest implementations of any VMware product. It's almost like click it to enable it, then you're almost done."
"The ease of use is great."
"The most valuable features are secure IOPs and LAN security."
"The solutions best feature is that it is easy to use."
"Pure Storage FlashArray could improve in the area of cryptographic information in the consoles. The user-friendliness could improve. The Pure Storage FlashArray team should come and log into the system with their maintenance credentials and then pull out the information as evidence of cryptography."
"It was not proactive communication."
"The backend of this solution utilizes an Active/Passive architecture, rather than an Active/Active architecture, which is a disadvantage, when compared to some of its competitors. Its storage capacity should be expanded in the next release."
"Data reduction is an area that needs improvement. There is a garbage collection service that runs but during that time, system utilization increases."
"The integration capabilities could be improved."
"I would like to see data tiering to AWS."
"Currently, the solution fails to support file screening."
"Pure Storage will have issues with positioning in the near future since its a relatively new company. For now, customers need a PoC to trust using the solution, as it can't stand on its brand name alone. They need to improve Pure Storage's marketing."
"I believe having more replication options comparatively to VMAX (other than RecoverPoint) would be great."
"Scalability is something that can be improved because there is an issue when it comes to mixing versions."
"Dell's technical support could be better."
"Management: At the time, there was no snapshot scheduler, so I had to write XSnapCourier to address it. The sad thing is that even after the newest release, which includes a native scheduler, most customers using XSnapCourier chose to stick with it due to a more feature-rich experience."
"Right now, external appliances are needed to replicate XtremIO to XtremIO, or to another EMC system."
"I am not too impressed with XtremeIO because we had a major failure."
"I would like to see the ease of deployment and built-in Metro clustering."
"XtremIO needs to be lower priced. It also needs better endpoints and scalability."
"Licensing costs are a little too high for smaller sized companies."
"Improvements can be made with respect to scalability."
"I have used the VMware Replication but I can't get it to work properly. The process should be simplified."
"It could have some automation. We haven't involved ourselves in a lot of automation around the vSAN environment capabilities. We're still running it using a very traditional setup. So, there could be some plugins to automate it using third-party environments, such as Jenkins."
"The pricing could be better when it comes to renewing the licenses."
"I would like to see more comprehensive lifecycle management. The current path and process for upgrading or updating the firmware, as well as the storage controller software to interact with that firmware, is fairly manual and not very well documented. A little more time and effort spent on the documentation of the lifecycle management for vSan would be really great."
"This product is very expensive."
"Some intelligence can be added to the newest version to provide more flexibility between storage tiers."
