We performed a comparison between Kaminario K2 [EOL] and VIOLIN QV2020 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 ease of management is one of the most valuable features of this solution. I would have also said that it's pretty fast but now our SQL servers are starting to beat it up pretty bad."
"All our junior partners can administer the storage arrays. It is simple and easy to use. We don't have to dedicate a whole team of full time people to work on it."
"They are quite responsive and our local team was pretty good."
"Performance, dedupe, and that it works well with database workloads are its most valuable features."
"It is always out of the box, and ready to use."
"The code upgrades are very smooth."
"The first year, we started out with one or five terabytes and it took what was 20 terabytes of storage down to less than one terabyte."
"It allows engineers to focus on other things rather than doing the more manual tasks. It automates tasks, so the ease of use is extreme. It simplifies the storage."
"The most valuable feature is definitely the always-on data deduplication."
"Implementation of the solution is very simple."
"The ratio between the physical storage and the storage we use is very high."
"The GUI is very straightforward and easy to use."
"Latency is definitely the big key for us."
"It provides a full feature set without separate licensing (deduplication, compression, snapshot, asynchronous replication, stable performance, etc.)."
"The capacity that we're saving by using Kaminario's K2 is giving us a four-to-one ratio for our deduplication."
"Inline compression"
"VIOLIN QV2020 is the latest in terms of performance. It has high-speed data access and processing capabilities, distinguishing it as a leader in its storage solutions category."
"It’s simple to use hardware to fix performance issues. Our issue is poor coding/queries. This greatly speeded things up. It’s too costly to track down poor programming in applications. The price of a developer’s time to scan through all the coding is high compared to buying Violin."
"I like what they're doing, but some of my customers complain that they do not have all the bells and whistles and knobs to fine-tune workloads that some of the competitors have. In my opinion, that's good. All customers don't have dedicated storage gurus, and they can get themselves into trouble if they fine-tune too many of those high-performance knobs, but they do get knocked down. Pure Storage takes a hit in the minds and opinions of some of the customers because they cannot customize things as much as compared to a legacy storage provider's appliance such as NetApp, Dell EMC, or even HPE. I personally think 95% of my customers are better off letting the system fine-tune itself. That was something that you needed to do 12 or 15 years ago, but now with all-flash, the technology can handle what it needs to handle. Customers just end up shooting themselves in the foot if they are tweaking too many default settings."
"When we were doing some tests, we found that there was an I/O freeze when they were switching the controller."
"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."
"The price should be lower."
"If we suddenly dump large amounts of data onto the storage system, it takes a while to process it."
"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."
"One thing I'd like to see in a future release is integration between their main storage array and what they call their FlashBlade product; to be able to snapshot directly from the primary array into multiple different backup copies on FlashBlade."
"I would rate this solution an eight. There's always room for improvement, nobody is perfect to get a ten out of ten. They do what they do well. It's not cheap but we it's for uses that we needed."
"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 front panel of the drive shelf doesn't always seat firmly."
"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 management graphical interface needs more improvement."
"A single pane of glass to monitor/manage multiple arrays would be helpful."
"The system currently has a 15TB LUN size limit and that snapshots need to be scheduled through script API instead of the GUI."
"I would like to see LDAP for the management panel; I've been notified they might be currently working on it."
"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."
"VIMM replacement is poorly designed. You have to slide out an entire drawer, remove the cover and then pop out the failed VIMM. I would like to see a front replacement just like with hard disks. This leaves room for error; for example, when you slide it out from the rack, you are moving cables along the cable management arm. This leaves the possibility of accidentally unplugging a cable from the array if it is not seated properly. Also, you might pinch the cables when sliding it back into the server rack."
"I set up Wi-Fi for storage, and since then, we haven't experienced any interruptions in service."
