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 latency is good."
"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."
"The solution is very straightforward to set up."
"The most valuable feature of this solution is its ease of use."
"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."
"The high availability of the product is the most valuable feature."
"The most valuable feature of this solution is reliability."
"The most valuable features are its performance and simplicity."
"We've never had an issue with storage."
"It has made deployment, configuration, and maintenance a lot simpler."
"We have simplified it down to where we're using one storage pool inside the Unity, whereas on the VNX, we had multiple storage pools. This has simplified that aspect for us. It would depend on each organization. We're heavy into VMware and this ties into it so simply. It's made it a lot easier for us. I create a datastore inside Unity, it just shows up in VMware. I love that tie-in."
"The hardware itself, it differs from Compellent and differs from the VNX before it. It doesn't have a separate file harbor that goes with it, there are no separate NAS heads. It's 2U, you have file and block storage, so you get a quite a lot of services for a small footprint."
"Scalability is good."
"There has been no downtime. It has built-in redundancy upon redundancy."
"The performance combined with the gig-per-dollar value is a combination that is superior to other storage options."
"Ease of management, aside from the serious performance, is the best feature."
"Performance and deduplication. This is a very robust block storage option that offers both performance and data optimization."
"Xtrem10's features are more simple to implement. The integration and interface are also good."
"The solution's most valuable features are the inline data reduction and deduplication."
"Dell XtremIO is good for databases and huge workloads."
"Snapshots are valuable because of their seamless nature, as well as the minimal space each snapshot takes."
"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."
"XtremIO’s capability to run any workload without much in the way of design considerations makes this very easy to use and size."
"We need better data deduplication."
"I'd like to see the product implement active replication for vehicles such as VMware."
"I would like to see replication and DR features in the next release of this solution."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"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."
"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."
"The UI for this solution needs to be improved."
"It's an expensive solution, particularly for medium companies. One device costs about 30,000 euros. The support contract is quite expensive as well. We are currently looking for other lower-cost solutions."
"I would like them to continue to build on the solution and expand on the functionality, like replication."
"Currently, the protocol SNMP is not implemented. That's a problem, as we follow this protocol and I can't check the integrity of this equipment."
"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."
"Problems with I/O modules, with bugs that came out that really should have been caught before the product was released."
"We've got an ongoing issue with a Unity where some power supply fans spin up. We've had a whole bunch of hardware changed as a result but I still have an open SR which has been a struggle. It doesn't seem to affect performance, but it's something that we're hoping the engineers can resolve. Also, we had some issues with an upgrade where we can't manage a device, after the upgrade. So we had to have a ticket in for that."
"It could be improved in the area of management flexibility. For example, I really need to set read-only access for LUNs, and there's no such option with Unity XT."
"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."
"They can improve the product by providing an HTML5-based interface instead of the Java GUI based application."
"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."
"Native data replication: To replicate data between XtremIO devices, you need to use EMC’s RecoverPoint appliances to move the data."
"Get rid of the Java aspect of the GUI console."
"The physical architecture could use some higher levels of redundancy."
"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."
"The product could be improved by reducing the pricing and having better organization in their technical support team."
"I believe having more replication options comparatively to VMAX (other than RecoverPoint) would be great."
