We performed a comparison between Dell Unity XT and Dell XtremIO based on real PeerSpot user reviews.
Find out in this report how the two All-Flash Storage solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"The high availability of the product is the most valuable feature."
"It has good, reliable, fast storage."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"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 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."
"Overall stability is very good. It is a very stable solution."
"The feature that I have found most valuable is the unified storage. Also, its capabilities for block-access, file access, and the center box."
"The compression and deduplication that will be coming in version 4.3. With just those features, you're reducing the amount of data and the footprint on the hardware."
"The most valuable feature is the integration with vCenter."
"It has reduced the latency in application and database reads and writes... All-flash, it's fast. We have the 650 model which is all-flash, upgraded from VNX. It just flies."
"We use the solution for site recovery manager, DR, and endpoint penetration."
"All-flash is a game changer. If you need performance, simple operations, and you plan to use it with VMware, it is a good choice."
"The solution allows for easy, useful replication with good features for VPLEX and VIVO."
"It has good performance."
"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."
"XtremIO 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."
"The feature I like most about Dell Xtremio is its hardware quality compared to other vendors. It's clear they're continuously improving their research and development."
"It has very good performance for an application which needs lower latency and a better response, for example, in microseconds."
"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."
"Initially, we faced numerous issues with our analytical systems. However, we saw performance improvement after the implementation of the solution."
"Speed and reliability:"
"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."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"The tool's pricing is higher than competitors."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"There is room for improvement in the pricing of the product."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"I would like to have secure mobile connectivity going forward. This would help me be more proactive."
"What I'd like to see is a little more detail on the networking side. I can go into where it's showing me the replication, but when I go into the network it just gives me broad-based information. I don't know which replication job is actually feeding it. I have to go in and rely on other apps."
"The solution can use improvement with the patch cluster like the Synchron and Active replication."
"Unity only does compression. It would be nice if there was a deduplication feature as well. At my previous job, we used XtremIO and that was deduplication and not compression, and I think we got more out of it because the more OSs you have that are the same, the fewer copies it needs to keep of all that data. So, the deduplication would be a nice feature to have."
"I think there are a couple of things on the file side that we're lacking from the VNX world. It would be nice if we got some of those back. I think there are limitations on how many file systems you can back up at a time. Whereas you can do, I believe, eight continuous per data mover on the file side on the VNX, you can only do something like two or four on Unity. If they could step up to that, that would be good."
"If you compare it with VMAX, where we communicate with the box through Solutions Enabler and there are a lot of commands and a lot of flexibility, the command line for Unity needs to enhanced."
"My only complaint would be some of the CLI Help files could be a little more detailed, but that's very minor complaint. We were trying to run some commands just to see how the storage snaps were interacting with the storage array, and it was a little difficult to look up exactly what commands should be run. The Help files detailing what exactly the commands did wasn't as detailed as we would have wanted them to be."
"We would like to see more advanced integration capability added to this solution."
"Management and reporting need improvement."
"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."
"The physical architecture could use some higher levels of redundancy."
"They can improve the product by providing an HTML5-based interface instead of the Java GUI based application."
"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."
"I believe having more replication options comparatively to VMAX (other than RecoverPoint) would be great."
"Right now, external appliances are needed to replicate XtremIO to XtremIO, or to another EMC system."
"XtremIO is coming to its end of life."
