We performed a comparison between Dell XtremIO and Pure Storage FlashArray 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."The high availability of the product is the most valuable feature."
"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."
"The latency is good."
"The most valuable features of this solution are its ease of use and performance."
"It has benefited my organization because it has reduced time to insights."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"The solution is scalable."
"Thin storage allocation"
"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 solution's most valuable feature is its high performance."
"Performance and deduplication. This is a very robust block storage option that offers both performance and data optimization."
"Ease of management, aside from the serious performance, is the best feature."
"Snapshots are valuable because of their seamless nature, as well as the minimal space each snapshot takes."
"The guaranteed sub-millisecond response time for a 4K block."
"The most valuable features are: complete performance and ease of use."
"Technical support is good."
"The mobile app is very helpful."
"The reliability is very good."
"Having fast storage allows actual servers to perform in high capacity so we don't have slowdowns on our applications."
"It is always out of the box, and ready to use."
"Their support system has insight into errors on our SAN fabric that we can't see. They've brought attention to and raised awareness for us about things that we couldn't see, when we were experiencing problems."
"The solution has probably reduced my power use substantially."
"It comes with a large number of features out-of-the-box, which makes it easy for us to see problems and manage capacity."
"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."
"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"The tool's portfolio is minimal. It is expensive."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"They could add more support for file storage and different types of storage."
"I'd like to see the product implement active replication for vehicles such as VMware."
"Get rid of the Java aspect of the GUI console."
"Scalability is something that can be improved because there is an issue when it comes to mixing versions."
"XtremIO is coming to its end of life."
"The GUI could be modified more in terms of how the different components are linked to each other."
"The physical architecture could use some higher levels of redundancy."
"I would like to see the ease of deployment and built-in Metro clustering."
"The solution needs to be simplified. When you integrate your storage with other systems, could use a little bit of automation."
"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."
"This product has only two active controllers, whereas other solutions can have more. This is something that needs to improve."
"I like what they're doing, but some of my customers complain that they do not have all the bells and whistles and knobs to fine-tune workloads that some of the competitors have. In my opinion, that's good. All customers don't have dedicated storage gurus, and they can get themselves into trouble if they fine-tune too many of those high-performance knobs, but they do get knocked down. Pure Storage takes a hit in the minds and opinions of some of the customers because they cannot customize things as much as compared to a legacy storage provider's appliance such as NetApp, Dell EMC, or even HPE. I personally think 95% of my customers are better off letting the system fine-tune itself. That was something that you needed to do 12 or 15 years ago, but now with all-flash, the technology can handle what it needs to handle. Customers just end up shooting themselves in the foot if they are tweaking too many default settings."
"I'd like to see a move towards individual VMs for what the performance of each VM is in a VD infrastructure. I can see the overall volume, but I would love to see things in a more granular level on the VM side."
"I would rate this solution an eight because we have had outages. The commit times went very high in the database. The whole array went down so our customers were down for around eight hours. This was a very big outage which could have been our fault because we didn't do the upgrade in time."
"I would like to see active replication. I know that it's available now but I haven't tried it yet. I hope that it works."
"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."
"The only time that we had problems with it was that there was a bug in the VVol implementation but, outside of that, it has been flawless."
"I would rate this solution an eight. To make it a ten it would have to be a little cheaper."
