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."For us, the most valuable feature is the compression and deduplication. Being able to deploy a three to one ratio for storage is absolutely critical in today's world with the growing need for storage and the growing need for more space."
"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 most valuable features in Pure Storage FlashArray are deduplication and active cluster."
"This solution is very scalable."
"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."
"I find two features of Pure Storage most valuable. The first is the "safe mode" function, and the second is its simplicity."
"It has been very stable. I have not seen or heard of downtime storage issues after moving over to it."
"We find the ease of usability and setup valuable."
"It has reduced complexity."
"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."
"The most valuable features include snapshots, Thin Clones, and deduplication and compression."
"The most valuable aspects of this solution are its stability, performance, and ease of updating."
"I like Unity XT's software-defined storage. It's a new feature that isn't widely used yet, but customers are impressed with it."
"Its most valuable feature is the storage alarm."
"I like that the solution is scalable. The initial setup is not complex. The basic licenses and software are included in the package. he primary advantage is that this product has been thoroughly tested and proven over time. I recommend this product."
"Compared to our old platform, everything is more tightly integrated. I don't have to go to different sections to do something. A lot of it is wizard-driven, so it's an easy to use system."
"Implementation of the solution is very simple."
"Logic/software management"
"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."
"Built-in snapshot support gives us SAN-side functionality most other platforms would have had us license separately."
"The most valuable feature is definitely the always-on data deduplication."
"Latency is definitely the big key for us."
"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."
"What it needs to do is work a little closer with solutions, like VMware, so it understands the particular workloads that are on it. Today, it does not understand the applications which are running against it."
"The internal garbage collection process has been fixed recently in some OS updates so it is more efficient but that could be just a little better."
"As long as they always improve on IOPS speed, that's all we're really looking for. The faster the storage can be the more we can do speed of application and speed of use."
"I would like the ability to swap out the network adapters into it. So, without taking out the whole controller, I would like to be able to swap adapters. This would make things easier."
"Pure Storage FlashArray could improve some aspects. There are certain features that are good and there are some features that I see some issues with at the technical level. Those issues are related to replication. They need to resolve those issues, which I have already highlighted to the Pure team. Additionally, there are some issues in the active cluster that could improve."
"I would like to see more cloud integration."
"Going forward, don't complicate things for the customers."
"It is a bit expensive."
"We had some issues recently because of a bug in the system. We were presenting LANs to the Unity array but I think it caused a disruption to the host. EMC did acknowledge it and provided an alternative way to do it."
"Dell Unity XT could improve the compatibility of some of the features. Some of my customers had some problems. Additionally, it would be beneficial for the solution to have advanced AI and ML features."
"The solution should include a free process in the HPE portal that uses serial numbers to verify that hardware is genuine."
"We did encounter a firmware bug which actually caused loss of data. There was some heartburn around that. But in general, it has operated as expected, except for that bug."
"We have only used this solution for less than one year so I don't have any improvements suggestions yet."
"We do a lot of VMware. It only integrates with VMware in one way, which is virtual volumes. I don't really have any visibility on anything else. From VMware, I can't look into Unity. From Unity, I can't look into VMware unless I am using virtual volumes, where they integrate together happily, but we are not using that. I would like better integration for non-virtual volume VMware use."
"They should update to the cloud."
"It needs deduplication. We'd like to have the dedupe capabilities in the Unity."
"The management graphical interface needs more improvement."
"A single pane of glass to monitor/manage multiple arrays would be helpful."
"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 like to see them work with Cisco, so it comes off the FIs, instead of having to go through my 10-gig network."
"The system currently has a 15TB LUN size limit and that snapshots need to be scheduled through script API instead of the GUI."
"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."
"The front panel of the drive shelf doesn't always seat firmly."
"I would like to see LDAP for the management panel; I've been notified they might be currently working on it."
