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.
"What I like most about this solution, is the speed, resiliency and scalability."
"Performance, deduplication, compression, and fast response time for requests from servers and applications."
"The tool is simple and easy to use. It has neat features like protection from device removal. Moreover, you can undo the deletes. The solution is easy to work with and not as complicated as CAC"
"We also like the compactness, the small footprint. It takes up very little space in a data center and uses little power."
"Scalability is one of the best features. You can quickly add more. You can swap out the drives with larger sizes, you can add more shelves. All of that is perfect - the whole concept of keeping it modular..."
"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 simplifies building out the storage."
"At this point, I don't know anything that they could provide in a better way."
"I don't think I've ever seen latencies above 10 milliseconds unless it was something that wasn't the array that was messing up. The thing is rock-solid."
"We have resolved IT challenges with this solution. It sped up our environment. We went from spinning disk to all-flash, which reduced our footprint."
"It is easy to manage. A lot of the system manages itself."
"The initial setup was very straightforward. Migration was smooth and configuration of the storage was quick and simple. The time needed to put it into production was less than expected, and data migration itself went without a glitch."
"It has improved the utilization of our own internal resources and performance across our managed service platform, meeting our customers SLAs."
"It is a workhorse and will run even demanding workloads."
"When I have an issue and need technical support, I reach out to them either through chat or by submitting a service request, and the response is good."
"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."
"A valuable feature of XtremIO is that, in terms of administration, it's simple and manageable."
"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."
"Very good IOPS performance"
"Dell XtremIO is good for databases and huge workloads."
"The guaranteed sub-millisecond response time for a 4K block."
"Thin storage allocation"
"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 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 initial setup of the product is complex."
"I would like to see more detailed reporting on the data. However, it would be nice to know what are the exact VMs usage after deduplication and/or what that VMs actual latency and bandwidth is, outside of VMware."
"We would like to see more development on their Copy Automation Tool (CAT) for Oracle, as well as better integration for our customers running Oracle VM."
"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 is not possible to create a cluster on top of multiple arrays."
"We haven't seen ROI yet."
"The solution could improve by having a multi-tenant feature."
"Had some issues with Purity not being entirely compatible with VMware ESXi."
"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."
"This solution could be improved by offering containerization. This is something many of my customers are looking for."
"Licensing has been quite difficult. It doesn't always auto-license. About half the time, when I provision one, I have to contact Service to get a license, or even go to our account manager to help get it straightened out."
"Licensing costs could be reduced."
"The NAS capabilities of Unity - I have to say there are a lot of things I miss. For example, deduplication for hybrid. I have tons of customers with VNX and dedupe. These customers achieve around 50% dedupe efficiency and they mostly use them for archive. If you're talking about 50TB of NAS, which is stored in a 25TB repository, which is very economical, and you can not provide that in a Unity hybrid box, you have problems."
"I would like the device to have the ability to pull down its own firmware. That would be a great thing."
"This product needs to have better integration with enterprise backup solutions and archiving devices."
"Replication with VMware - it's called the vSphere Metro Storage Cluster - is lacking in the Unity and is present in Compellent."
"The physical architecture could use some higher levels of redundancy."
"Dell's technical support could be better."
"I believe having more replication options comparatively to VMAX (other than RecoverPoint) would be great."
"I would like to see the ease of deployment and built-in Metro clustering."
"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."
"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."
"The product could be improved by reducing the pricing and having better organization in their technical support team."
"Right now, external appliances are needed to replicate XtremIO to XtremIO, or to another EMC system."
