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."With Pure Storage, we don't see any latency or IOPS. It has been a very seamless integration."
"This solution has improved our organization. In the past, we had reports that were taking up to two hours and after switching to SSD storage the overall processing power dropped to half an hour. The end users saw an immediate performance gain."
"The management is simple in Pure Storage FlashArray."
"The security operating system is its most valuable feature because it's very simple, easy to use, and operate. You don't have to do very serious training to operate this equipment. It's user-friendly and pretty straightforward."
"I have seen a huge increase in speed and performance on our databases."
"It upgrades in place which means we'll be using it well into the future."
"The connections are a lot faster than what we had in the past. One InfiniBand does what we did on all of our Fibre Channels."
"It's reduced our overhead management time on storage, since it is so simple to get in and just provision a volume, present it to the host, and then you are done."
"It has reduced complexity."
"VMware integration makes the life of our engineers easier, as we are almost 100% virtualized and this feature is used on a daily basis."
"In the hybrid version, I would say they are fast. They have fully automated storage tiering. In the all-flash version, higher performance, compression, data replication."
"I like the ease of configuration, the quick setup and the fact that it seems to be hardened. We haven't had any issues with them. In terms of simplicity of ownership, once they're running you don't have to touch them. They're also simple to manage. We came from the VNXe 3200s so it's very similar."
"I like that the performance is very good."
"With all-flash it should be able to scale. You probably just need one 4U device and you have terabytes of space."
"The Snapshot feature is key."
"They've integrated NAS and SAN pretty well. It made replication very simple. Because one of our systems has a lot of LANs, for it to replicate we have Consistency Groups in there. That's something that is really helpful, making sure that everything is working not just for replication but for backups as well."
"XtremIO’s capability to run any workload without much in the way of design considerations makes this very easy to use and size."
"Dell XtremIO is good for databases and huge workloads."
"Xtrem10's features are more simple to implement. The integration and interface are also good."
"The most valuable features are: complete performance and ease of use."
"The performance is good, which is important."
"Performance and deduplication. This is a very robust block storage option that offers both performance and data optimization."
"The most valuable features are that it is fast and reliable."
"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%."
"I would rate this solution an eight. To make it a ten it would have to be a little cheaper."
"Some services could be inserted directly into the SAN, so Pure Storage could complete with the HyperFlex."
"We do have an issue with the vCenter integration. Pure Storage says it has a lot of free space, but vCenter says its completely full. This is because their dedupes are saved as space, but Vcenter still detects the disk as completely full. So, we do have an issue with that."
"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 a feature to integrate with external or cloud solutions. For example, if I want to use this storage for a backup from the cloud, I want to have integration with the cloud vendors, such as Microsoft, Oracles, or Amazon. It could be available as an API to allow seamless integration. Additionally, the solution could improve by having native integration with a cloud provider, such as VMware or Microsoft, this would reduce the need to use third-party solutions to complete the task."
"The system has dual controllers but does not have a high level of resiliency built-in."
"If we suddenly dump large amounts of data onto the storage system, it takes a while to process it."
"Areas for improvement would be the financial operations. In the next release, I would like to see a NAS protocol included."
"We have had some downtime. Nothing is perfect. Unity’s have had some code-release problems, versions that, from a compatibility perspective, had some glitches which caused an outage. But, given the amount of Unity’s we run, that has been fairly minor and it hasn't happened at scale or across all of our Unity’s."
"It's very frustrating that it's not backward-compatible with the previous platforms, so it's a struggle for a lot of our customers."
"Last (and I understand that it has a low chance of being implemented) the copy services currently are redirect on write. It would be great if the administrator could choose between redirect on write and copy on write, when configuring copy job."
"I don't know where the hybrid cloud might be going or what connectivity there is between what was recently released as far as AWS and being able to manage both of them. Maybe there is an on-prem and an AWS instance in the same window, like a single pane, but I would like to see something along those lines, where there wouldn't be two locations to manage storage."
"The pricing is a bit high. We'd like it to come down."
"I would like to see them add Storage Groups, like we have had in Clariions and VNXs."
"Its replication technology could be better."
"I would like the device to have the ability to pull down its own firmware. That would be a great thing."
"I would like hardware capacity additions to be a little more flexible. The upgrade path for the existing XTremIO units requires you to purchase 2 XBricks at a time and they need to be the same capacity as the existing XBricks."
"Right now, external appliances are needed to replicate XtremIO to XtremIO, or to another EMC system."
"This solution is geared toward enterprise-level companies. Small and medium-sized businesses would find it extremely expensive."
"If you are looking at flash storage solutions, XtremIO doesn't offer any unique features. Most of my customers are migrating their workload from XtremIO to other formats because of this."
"In the next release, the solution could have better integration and if we can host assets on the cloud, such as NetApp has the NetApp volumes, which we can host on the cloud directly called NetApp CVO (cloud volume ONTAP). Dell EMC should come up with something purely on the cloud rather than manage services."
"Ease of use is key in the converged and hyper-converged world that requires administrators to have both hypervisor and storage skills."
"I am not too impressed with XtremeIO because we had a major failure."
"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."
