We performed a comparison between Dell Unity XT and Kaminario K2 [EOL] based on real PeerSpot user reviews.
Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."The initial setup is very straightforward. You simply plug it in and turn it on."
"I use all the features of this solution and I find them to be easy to use and functional, such as the compression and capacity to expand."
"One of the lesser sung advantages was when we started running our interface engine on Pure Storage. The ability to process messages and pass them through in our organization skyrocketed purely because of a disk that I owned which we were getting out of Pure Storage."
"Performance, dedupe, and that it works well with database workloads are its most valuable features."
"Because of the encryption, we have different storage and the encryption can go over both."
"Very efficient storage"
"Their technical support is excellent. It's the best out of any of the vendors we work with."
"It helps us maintain uptime much better than other solutions we've used in the past, and the support is extremely quick and responsive."
"It is pretty stable. I like the stability, because everything works like it should. We made it all redundant. So, we don't have anything to worry about."
"They have a Unity REST API that I use to automate some of the storage stuff. I'm just getting started with it, but it seems pretty easy to use."
"Quick Snapshots and cloning are key features."
"Dell Unity XT is user-friendly and easy to use."
"It is ease to use. It performs. It's easy to provision, and It's stable."
"The valuable features of Unity include that it's flexible, has a friendly user-interface, and provides good performance."
"The most valuable thing for our use case is the flexibility to have multiple-protocol support."
"The performance is great. We have four or five different Unity arrays, and they have all run flawlessly."
"It provides a full feature set without separate licensing (deduplication, compression, snapshot, asynchronous replication, stable performance, etc.)."
"Inline compression"
"The most valuable feature is definitely the always-on data deduplication."
"The capacity that we're saving by using Kaminario's K2 is giving us a four-to-one ratio for our deduplication."
"Data reduction and snapshot abilities: Smaller footprint in the datacenter (lower cost for power, cooling, etc.)."
"The speed and, for us in particular in what we're doing, the data de-duplication."
"The GUI is very straightforward and easy to use."
"The increased performance is many times above our previous array performance in all metrics. Integration with vSphere features is also a definite plus."
"Beyond a certain amount of petabytes, you have to have a separate system. Basically, it's not infinitely scalable."
"It's not so scalable. It's got moderate scaling capabilities right now. The clustering technology needs a bit of work, they need to improve that."
"Data reduction is an area that needs improvement. There is a garbage collection service that runs but during that time, system utilization increases."
"Automation could be simplified."
"The number of Filesystems is limited, which it is not on the EMC VNX."
"Part of our company works on Dell EMC because Pure Storage did not have synchronous applications when we were purchasing our products."
"The system has dual controllers but does not have a high level of resiliency built-in."
"There was some complexity in the initial setup."
"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."
"Unity only does compression. It would be nice if there was a deduplication feature as well. At my previous job, we used XtremIO and that was deduplication and not compression, and I think we got more out of it because the more OSs you have that are the same, the fewer copies it needs to keep of all that data. So, the deduplication would be a nice feature to have."
"This product needs to have better integration with enterprise backup solutions and archiving devices."
"Since Dell took over EMC, the support has been very bad. Before, the support was fine. Now, the support is slow or they don't react."
"I would like it to be a little bit easier to contact support. We can contact support, but we have to go through a phone tree. We get routed to different places. I might call support to say that I need a drive replaced and get transferred to three different groups before I get to the group I actually need."
"I would like better integration with RecoverPoint. My major issue with the solution, all around, has been RecoverPoint more than Unity. While I like the easy user interface, I would like some more advanced features for troubleshooting built into the product, so that we can do more in-depth problem-solving."
"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."
"There are some features in VNX that I wish were in the Unity. For example, Storage Groups for isolating LANs and hosts. That is a big issue."
"Access to technical support should be improved for our region. Technical support is good, but they're very hard to access."
"The interface look and feel could be improved."
"A single pane of glass to monitor/manage multiple arrays would be helpful."
"I would like them to improve the look of the product’s external casing and shelves."
"The system currently has a 15TB LUN size limit and that snapshots need to be scheduled through script API instead of the GUI."
"I think it should have better performance with small files. With big data, its performance is top notch, but it is difficult to load small files."
"Some of the nice to haves for us, in terms of today, would be VVols but again, it’s not a critical feature."
"I would love to see capacity on its DRAM. I know it's not cost effective for them to do it, but I think that it could be a big differentiator and was a big differentiator from the beginning."
