We performed a comparison between Kaminario K2 [EOL] and VMware vSAN 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 simplicity of it. The performance is good, but the simplicity is the best thing. Storage management is quite complex, but Pure Storage is easy to manage."
"Lone segmentation is simpler and more agile. It's improved the velocity in overall provisioning from project to operation."
"The most valuable feature of Pure Storage FlashArray is its high stability level."
"The performance of the storage is just unbelievable."
"Having fast storage allows actual servers to perform in high capacity so we don't have slowdowns on our applications."
"The solution helps to simplify storage."
"The all-flash disc is the most valuable feature of this solution."
"It is pretty much just plug and play. There is not that much to do with it. It is very easy to use."
"Implementation of the solution is very simple."
"The increased performance is many times above our previous array performance in all metrics. Integration with vSphere features is also a definite plus."
"The ratio between the physical storage and the storage we use is very high."
"The GUI is very straightforward and easy to use."
"The most valuable feature is definitely the always-on data deduplication."
"The capacity that we're saving by using Kaminario's K2 is giving us a four-to-one ratio for our deduplication."
"Scale out is a differentiator for them, especially in the enterprise market. It's key for a lot of customers."
"Latency is definitely the big key for us."
"I have found that the multi-homing feature is very valuable in VMware vSAN. It is an easy-to-use solution."
"The feature that I have found most valuable is that it is easy to deploy. It is easy to create and delete virtual servers. It is easy to create the load balancing and the clustering."
"The product’s most valuable features are performance and expandability."
"The scalability is very good and the solution is stable and reliable."
"The vSAN features we've found most helpful are live application migrations and storage policies. It has storage, policies, application, and DRS policies. Automation is there."
"We didn't only choose vSAN; we chose VMware because of SR-IOV, which is more on the hypervisor level and not on the vSAN storage. It's part of the whole system."
"I have found the solution to be scalable."
"The most valuable feature of VMware vSAN is you do not have to use additional hardware for storage. The operation of VMware vSAN does not take a lot of effort. If you have VMware technology on your site, then it's easy for the operational support of the system."
"This product has only two active controllers, whereas other solutions can have more. This is something that needs to improve."
"We need to add more storage in Pure Storage FlashArray with the cluster mode activated for us to have better performance."
"It is not possible to create a cluster on top of multiple arrays."
"If they could make it cheaper, that would be something."
"When we were doing some tests, we found that there was an I/O freeze when they were switching the controller."
"The number of Filesystems is limited, which it is not on the EMC VNX."
"Just some nit picky stuff, like allowing servers and volumes to be grouped. Therefore, it would easier to work with them in the GUI."
"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."
"I would like them to improve the look of the product’s external casing and shelves."
"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 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."
"The management graphical interface needs more improvement."
"Some of the nice to haves for us, in terms of today, would be VVols but again, it’s not a critical feature."
"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."
"A single pane of glass to monitor/manage multiple arrays would be helpful."
"The pricing model is sometimes a challenge for us because their licenses are very costly."
"Troubleshooting tools could be improved."
"VMware vSAN needs to improve its features because other solutions have more advanced features."
"Some intelligence can be added to the newest version to provide more flexibility between storage tiers."
"Its price could be improved. It is too expensive for our clients."
"The price for the hard drive, for vSAN, is very expensive."
"I would have liked it to have been more scalable. It's scalable but not as much as, for example, the ScaleIO systems were or the Kaminario"
"We would like to see additional backup and recovery options added. In particular, integration with popular applications like databases."
