We performed a comparison between Dell XtremIO and VIOLIN QV2020 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."We like the data reduction rates. That has been really helpful. You get 4U of Pure storage replacing something like two racks of spinning disks. One of the things that has contributed to that are the data reduction rates."
"The tool is simple and easy to use. It has neat features like protection from device removal. Moreover, you can undo the deletes. The solution is easy to work with and not as complicated as CAC"
"It worked flawlessly."
"It helps us maintain uptime much better than other solutions we've used in the past, and the support is extremely quick and responsive."
"We have tons of capacity on it."
"The predictive performance analytics are good."
"I like the speed, and I like the API and how programmable it is."
"FlashArray has many valuable features. It's very user-friendly and it has high availability, so there is comparatively less downtime. During maintenance, there is no shutdown procedure, so you can directly power off the Array and manage the shutdown process without any data loss, which is a unique feature. Managing replication and data migration is also very easy."
"A valuable feature of XtremIO is that, in terms of administration, it's simple and manageable."
"Ease of management, aside from the serious performance, is the best feature."
"Speed and reliability:"
"The most valuable feature of Dell EMC XtremIO is the data protection (DP) group, it is one of the most advanced features in these types of arrays. The dedupe and compression that this array provides both do a superb job."
"It was very easy and straightforward to setup."
"Xtrem10's features are more simple to implement. The integration and interface are also good."
"The Metro clustering and solid-state performance, are the most valuable features of this solution."
"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."
"VIOLIN QV2020 is the latest in terms of performance. It has high-speed data access and processing capabilities, distinguishing it as a leader in its storage solutions category."
"It’s simple to use hardware to fix performance issues. Our issue is poor coding/queries. This greatly speeded things up. It’s too costly to track down poor programming in applications. The price of a developer’s time to scan through all the coding is high compared to buying Violin."
"The data reduction that we had initially anticipated when we bought Pure and we move over, is way lower than the expected reduction. It depends on the workloads, of course. But that has been a challenge at times."
"We would like to see more cloud support, which we know is coming, although it's not out yet. It's going to be released in the next versions. That would be the biggest win, if additional cloud support is built into the array."
"The higher education moves slowly. We are still looking forward to implementing the full list of existing features."
"In the configuration, which we brought in or tested it in, it has a very limited config as far as the array goes. That said, it still did more than our anticipation."
"I would like some form of QoS implemented. As a service provider, it would be beneficial to have it."
"Pure Storage FlashArray could improve by being more secure."
"We would like more extended historical data to help with some of the capacity planning. This is something that we are asking for all the time. E.g., what was the historical performance of this particular volume? So, we would like more historicals."
"Areas for improvement would be the financial operations. In the next release, I would like to see a NAS protocol included."
"They can improve the product by providing an HTML5-based interface instead of the Java GUI based application."
"Scalability is something that can be improved because there is an issue when it comes to mixing versions."
"Get rid of the Java aspect of the GUI console."
"Management and reporting need improvement."
"The GUI could be modified more in terms of how the different components are linked to each other."
"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."
"It is very expensive to scale. You have to buy an additional system to extend from one disc, for instance. It is scalable, but extremely expensive to do so."
"Dell's technical support could be better."
"I set up Wi-Fi for storage, and since then, we haven't experienced any interruptions in service."
"VIMM replacement is poorly designed. You have to slide out an entire drawer, remove the cover and then pop out the failed VIMM. I would like to see a front replacement just like with hard disks. This leaves room for error; for example, when you slide it out from the rack, you are moving cables along the cable management arm. This leaves the possibility of accidentally unplugging a cable from the array if it is not seated properly. Also, you might pinch the cables when sliding it back into the server rack."
