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."The most valuable feature is it never goes down. We can expand and create volumes."
"What I like most about this solution, is the speed, resiliency and scalability."
"For us, the most valuable feature is the compression and deduplication. Being able to deploy a three to one ratio for storage is absolutely critical in today's world with the growing need for storage and the growing need for more space."
"The technical support is very good."
"All our junior partners can administer the storage arrays. It is simple and easy to use. We don't have to dedicate a whole team of full time people to work on it."
"The most valuable feature of Pure Storage FlashArray is the complete set of functions it provides."
"The speed of the Pure FlashArray is very, very fast and nothing in the market can compare to it."
"The most valuable feature is its speed."
"It has helped us be able to use less administrators per device or system. Therefore,we are more streamlined."
"There are also DR and data protection functions that we found in the new Unity, now that we are stepping up from VNX and other storage appliances, that we've started implementing."
"We can get almost real-time response times."
"We run about 100 virtual servers on it. We have about 100 users accessing the file shares from there, and I've seen no problem with that. We have about a 10GB backbone. Whatever we throw at it, it hasn't shown any sign of weakness or anything. It's been really good."
"The most valuable features include snapshots, Thin Clones, and deduplication and compression."
"On a scale from one to 10, I'd probably give EMC customer support an 11. It's been really good. We do have premium support, which means if we have a problem, it gets solved really quickly."
"You can add volume and it's automatically registered in VMware."
"Replication of the communication object (COB) scenarios"
"Deduplication and cloning capability"
"Very good IOPS performance"
"The solution's most valuable feature is its high performance."
"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."
"Thin storage allocation"
"A valuable feature of XtremIO is that, in terms of administration, it's simple and manageable."
"The solution's most valuable features are the inline data reduction and deduplication."
"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."
"A minor issue that comes to mind is that, every once in a while, a hard drive will go bad."
"The price of this solution could be improved."
"The way Pure Storage does the controller storage warranty or replacement has been an issue for some people who just replace the controllers every couple of years, and that's where some of the confusion with pricing and support has come in. They should be clear on the way the controller replacements happen, as it is important to know whether or not you can get a good return on them, because it can be a little confusing."
"This product has only two active controllers, whereas other solutions can have more. This is something that needs to improve."
"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."
"It goes at about 95 percent, so we have had some performance issues. It is hard to clear them."
"Some services could be inserted directly into the SAN, so Pure Storage could complete with the HyperFlex."
"In the next release of this solution, we would like to see automated copy data management for SQL Server."
"Improve the administrative user interface so it is easier to work with. Currently, a simple task, such as removing a host from 100 LUNS, takes a lot of time. If they could improve LUN to host model to be more like the EMC VPLEX, for example, it would be great."
"They should update to the cloud."
"Scalability is not good. We have a Unity 300, now we have to do a data-in-place conversion for the next upgrade because only 150 slots are supported, not drives, only slots."
"It's not as reliable as it should be, I think it was probably released a little early. We've had production problems with customers, and there are still some challenges at scale as well. Compression is a problem for the system. Once you enable dedupe and compression, the performance of the system, the capability, halves... It has to be right-sized and sized for compression, but even with that, because there are only two storage processors, you're ending up at almost 40 percent usage."
"I would like to see more integration with other products."
"It isn't easy to find trusted partners for the product. The solution has issues with mid-level storage and does not come with enterprise storage."
"In the dashboard there could be notification of duplicate files and the like, so we don't have to rely on Windows to do that."
"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."
"Scalability is something that can be improved because there is an issue when it comes to mixing versions."
"One thing that should be improved is the reporting and monitoring tools. It should use real time monitoring for storage, IOPS, latency, etc."
"Sometimes we don't get an immediate response from the support team. The initial POC also took a lot of resources."
"Management and reporting need improvement."
"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."
"I would like to see more scalability."
"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."
"I am not too impressed with XtremeIO because we had a major failure."
