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."We're getting good performance, and the compression ratio is also very good in Pure Storage FlashArray."
"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."
"The sales and executive support have been outstanding compared to the rest of the market... My upgrade paths have been simple on the Pure... It's a lot simpler to implement and a lot simpler to manage."
"It is an easy to use product for all of my team members."
"Having an intuitive user interface to get things running is great."
"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 are the replication of data and the continuous snapshot that we can take from the disc."
"Simplicity and reliability are the most valuable feature of Pure Storage FlashArray."
"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."
"Unity's are more easily administrated, so we need fewer people to do the administration. We have less overhead because of that."
"The most valuable features of Dell Unity XT are the data compression for all of our VMs up to four times and the performance is good."
"I like the easy management with the new Unisphere management and the HTML5 interface."
"With all-flash it should be able to scale. You probably just need one 4U device and you have terabytes of space."
"I like that when you log in it gives you a dashboard of what your storage looks like."
"Using this solution has meant that I do not need to look for different partners to provide me with solutions like a backup service. Dell provides end to end solutions."
"Veeam Backup integration: Veeam is the defacto standard for backing up of virtual environments."
"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."
"Scale out is a differentiator for them, especially in the enterprise market. It's key for a lot of customers."
"Logic/software management"
"The increased performance is many times above our previous array performance in all metrics. Integration with vSphere features is also a definite plus."
"The most valuable feature is definitely the always-on data deduplication."
"The most valuable aspect is the use of solid-state storage drives instead of spinning drives."
"The GUI is very straightforward and easy to use."
"The capacity that we're saving by using Kaminario's K2 is giving us a four-to-one ratio for our deduplication."
"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."
"I would rate this solution an eight because we have had outages. The commit times went very high in the database. The whole array went down so our customers were down for around eight hours. This was a very big outage which could have been our fault because we didn't do the upgrade in time."
"Some services could be inserted directly into the SAN, so Pure Storage could complete with the HyperFlex."
"The number of Filesystems is limited, which it is not on the EMC VNX."
"Automation could be simplified."
"The higher education moves slowly. We are still looking forward to implementing the full list of existing features."
"Pure Storage FlashArray could improve in the area of cryptographic information in the consoles. The user-friendliness could improve. The Pure Storage FlashArray team should come and log into the system with their maintenance credentials and then pull out the information as evidence of cryptography."
"There are a lot of things to improve."
"One area of improvement is replication. We are also using Oracle virtual machines, and when you are using systems from other vendors, the process of replicating from Unity through OLVM is more laborious than when we were using VPLEX."
"Having more artificial intelligence tools built into the solution would be a great benefit. This would allow us to see more about the workloads and higher visibility, such as performance degradation."
"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."
"There is an issue with data duplication occurring on the flash memory. It should be improved. Timely updates and upgrades to the latest versions would be great."
"The pricing is a bit high. We'd like it to come down."
"Our request to Dell EMC for improvement was in the reporting and monitoring areas. Dell EMC built up a cloud ID so that we could see the overall storage numbers. We needed to have the proper KPIs to be able to see and manage things."
"Scalability is not good. We have a Unity 300, now we have to do a data-in-place conversion for the next upgrade because only 150 slots are supported, not drives, only slots."
"The support team is well-versed in the AMG solution, having received comprehensive training. They also boast strong partnerships in both VNAM and Korea. The system's user-friendliness is a primary consideration in their choice of solution, emphasizing the importance of service. They place a strong emphasis on service, occasionally requiring approvals. However, with full installations, they have achieved almost uniformity. Their storage approach differs from a consolidated business-based model; instead, it is application-centric. Their investment in solutions is geared towards specific needs, such as the banking or information system, acquiring smaller storage units individually."
"Access to technical support should be improved for our region. Technical support is good, but they're very hard to access."
"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 management graphical interface needs more improvement."
"I would like to see LDAP for the management panel; I've been notified they might be currently working on it."
"The front panel of the drive shelf doesn't always seat firmly."
"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."
"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."
"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."
