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."Performance is the most valuable feature."
"Provides fast access and is user-friendly."
"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"
"Because we were able to afford to go all flash, we don't manage the tiers, we're not moving data up, and we're not waiting for overnight cycles."
"The most valuable features in Pure Storage FlashArray are deduplication and active cluster."
"The performance is very good."
"The mobile app is very helpful."
"I have seen a huge increase in speed and performance on our databases."
"The most valuable feature of Dell Unity XT is data duplication. Additionally, the management interface is simple, and is not a hassle using it. You don't need too much to learn or to be familiarized with it."
"The most valuable features are its performance and simplicity."
"It has reduced complexity."
"The performance combined with the gig-per-dollar value is a combination that is superior to other storage options."
"It is easy to scale, maintain, and manage."
"The inline deduplication and data reduction capabilities have been the most valuable."
"We currently have two Dell EMC Unities going. One of them at our primary on-premise DR site. They communicate with each other. If we ever have to failover, it is right there and ready."
"This solution is easy to work with and easy to maintain."
"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."
"Built-in snapshot support gives us SAN-side functionality most other platforms would have had us license separately."
"Scale out is a differentiator for them, especially in the enterprise market. It's key for a lot of customers."
"The most valuable aspect is the use of solid-state storage drives instead of spinning drives."
"The capacity that we're saving by using Kaminario's K2 is giving us a four-to-one ratio for our deduplication."
"The most valuable feature is definitely the always-on data deduplication."
"The increased performance is many times above our previous array performance in all metrics. Integration with vSphere features is also a definite plus."
"Pure Storage FlashArray could improve the recent file storage capabilities because it is lacking a lot of features."
"The way Pure Storage does the controller storage warranty or replacement has been an issue for some people who just replace the controllers every couple of years, and that's where some of the confusion with pricing and support has come in. They should be clear on the way the controller replacements happen, as it is important to know whether or not you can get a good return on them, because it can be a little confusing."
"In the configuration, which we brought in or tested it in, it has a very limited config as far as the array goes. That said, it still did more than our anticipation."
"We understand that they're thinking about it, but one of the things that would be nice is if they added some basic file-level capabilities to the platform. The idea is that they would run a basic NFS or CIF share from the controllers. FlashBlade is the powerhouse for File and Object storage, but if you don't need all that power, a lightweight file function would make FlashArrays more versatile."
"I would rate this solution an eight. To make it a ten it would have to be a little cheaper."
"The support for NFS protocols right out-of-the-box need improvement. I'm used to other storage vendors who have NFS support right out-of-the-box, and Pure Storage doesn't seem to have anything."
"FlashArray's capacity for forecasting should be improved because it needs to be a bit more current. I think it's bundled with the deduplication and other compression factors. We need more user interfaces for forecasting in this software and more interfaces need to be integrated with this array management tool."
"There's always an opportunity for new feature functionality."
"They should have more wizards for customers so they can do more of the self-service types of functions, in terms of upgrades and patching, although it's pretty easy right now."
"Dell Unity XT could add a unit-to-unit replication. We haven't seen that because we don't have an additional one to test. However, it is not an improvement, but something that we would like to have visibility on how it's done or how it works."
"In future releases, I would like to see automatic upgrades from one to the next, when this system is coming out and the next one is coming in; more akin to what Pure Storage is doing. That would be really helpful."
"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."
"In terms of what could be improved, I would say its capacity and its connection."
"On the data domains - for the Unity product, but specifically for data domain - I would like a much easier interface for managing, for actually going in and having one place where I could get all of the different parts of the overall unit. And I would also like to be able to identify individual disks a lot more easily."
"The pricing is a bit high. We'd like it to come down."
"I would like to have secure mobile connectivity going forward. This would help me be more proactive."
"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 front panel of the drive shelf doesn't always seat firmly."
"I would like to see them work with Cisco, so it comes off the FIs, instead of having to go through my 10-gig network."
"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."
"The system currently has a 15TB LUN size limit and that snapshots need to be scheduled through script API instead of the GUI."
"A single pane of glass to monitor/manage multiple arrays would be helpful."
"The interface look and feel could be improved."
"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."
