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."As soon as we introduced our first Pure Storage FlashArray, the first benefit was at least twice the performance increase. Our production databases simply ran twice as fast with no other change."
"We can store more for a cheaper price as opposed to paying for larger devices and larger rack spaces which get outdated sooner and which we'd have to change every two years. It simplifies storage for us."
"Data reduction and compression. Sub millisecond latency."
"This is the best all-flash storage array on the market."
"I never have to worry about its performance or if it is the root cause of an issue."
"The best feature is consistently lower latency, even when IOPS crank up to over 75K. The product maintains submillisecond response time, which is incredible."
"The initial setup was really straight forward."
"We put a fair amount of stress on it because we run sequel workloads and we run web applications where the same web files are hit over and over. We have had almost zero stability issues with that SAN, that has been really great for us."
"We particularly like the user interface on cloud IQ with this product."
"It is very stable."
"Unity's are more easily administrated, so we need fewer people to do the administration. We have less overhead because of that."
"It is lightning fast, low on power and heat, and has a small footprint with great performance."
"The UI itself is fantastic, and the ease of administration is far better than Unisphere or Navisphere ever were. It's very easy to manage. The fact that it has built-in APIs means our automation people can help us automate a lot of tasks, and that has been helpful. And, of course, it's really fast. Obviously, that doesn't hurt anything at all."
"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."
"User friendly interface"
"I like that when you log in it gives you a dashboard of what your storage looks like."
"The increased performance is many times above our previous array performance in all metrics. Integration with vSphere features is also a definite plus."
"Scale out is a differentiator for them, especially in the enterprise market. It's key for a lot of customers."
"The capacity that we're saving by using Kaminario's K2 is giving us a four-to-one ratio for our deduplication."
"Built-in snapshot support gives us SAN-side functionality most other platforms would have had us license separately."
"Data reduction and snapshot abilities: Smaller footprint in the datacenter (lower cost for power, cooling, etc.)."
"Ease of use: My installers - my administrators over the system - they love how easy and fast it is to install and spin up a LUN and get going."
"The speed and, for us in particular in what we're doing, the data de-duplication."
"Implementation of the solution is very simple."
"It would be good to have metrics of the box's performance so we can see what it delivers, but currently, I can't see what it's actually doing."
"The price should be lower."
"It goes at about 95 percent, so we have had some performance issues. It is hard to clear them."
"The price of this solution could be improved."
"I would love for them to have a hyper-converged solution."
"In the next release of the solution I would like to see Vormetric native block encryption."
"I recognize it's a difficult challenge, but I would like to see them make the pricing more reasonable."
"Currently, the solution fails to support file screening."
"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 is a tier-three solution and it gives us what we need for archiving and backups."
"I would like to see a more seamless virtual box integration with the physical box which can replicate, because the setup of the replication is very difficult right now."
"I think there are a couple of things on the file side that we're lacking from the VNX world. It would be nice if we got some of those back. I think there are limitations on how many file systems you can back up at a time. Whereas you can do, I believe, eight continuous per data mover on the file side on the VNX, you can only do something like two or four on Unity. If they could step up to that, that would be good."
"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."
"It could be a little easier to attach it to a network file system."
"Ordering is easy, but the processing site and working with those companies was difficult."
"I would like them to continue to build on the solution and expand on the functionality, like replication."
"The management graphical interface needs more improvement."
"Improved scale and budget planning with flexibility of the solution for budget needs and efficiency for growth with the great optimization ratio due to the nature of our use."
"The interface look and feel could be improved."
"I would like to see LDAP for the management panel; I've been notified they might be currently working on it."
"I'm hoping to see Active Directory integration. Right now, you still have to use a local admin account to log in and manage everything."
"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."
"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."
"Access to technical support should be improved for our region. Technical support is good, but they're very hard to access."
