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 best feature is consistently lower latency, even when IOPS crank up to over 75K. The product maintains submillisecond response time, which is incredible."
"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."
"It's very fast and very easy to use. It performs well and is both flexible and compatible. We like it because it's easy to use."
"The scalability is good."
"It is pretty much just plug and play. There is not that much to do with it. It is very easy to use."
"The reliability is very good."
"Data deduplication is one feature I found to be the most valuable in the tool...Stability-wise, I rate the solution a ten out of ten."
"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."
"Latency is definitely the big key for us."
"Scale out is a differentiator for them, especially in the enterprise market. It's key for a lot of customers."
"The increased performance is many times above our previous array performance in all metrics. Integration with vSphere features is also a definite plus."
"Data reduction and snapshot abilities: Smaller footprint in the datacenter (lower cost for power, cooling, etc.)."
"Implementation of the solution is very simple."
"The GUI is very straightforward and easy to use."
"The speed and, for us in particular in what we're doing, the data de-duplication."
"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."
"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."
"It completely removes the need for a storage network and for a storage administrator and all of that infrastructure and the costs that are involved with them."
"The product's initial setup phase is simple."
"Technical support has been very good. They respond pretty fast, especially if we have a critical issue. Their responses have been great."
"Very good VCG notification feature."
"The migration of servers feature makes server rack maintenance easy."
"One of the valuable features of vSAN is it has a universal type of technology that allows you to deploy it on any server or hardware. Competitors, such as Nutanix, provides the AOS and can be deployed only on certified hardware. For vSAN, it does not require any kind of certified hardware."
"Allows us to implement more quickly, and to ease the maintenance."
"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."
"The technical support is okay, but could be improved."
"There's always an opportunity for new feature functionality."
"I would like a feature to integrate with external or cloud solutions. For example, if I want to use this storage for a backup from the cloud, I want to have integration with the cloud vendors, such as Microsoft, Oracles, or Amazon. It could be available as an API to allow seamless integration. Additionally, the solution could improve by having native integration with a cloud provider, such as VMware or Microsoft, this would reduce the need to use third-party solutions to complete the task."
"I would like to see more detailed reporting on the data. However, it would be nice to know what are the exact VMs usage after deduplication and/or what that VMs actual latency and bandwidth is, outside of VMware."
"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."
"A minor issue that comes to mind is that, every once in a while, a hard drive will go bad."
"Currently, the solution fails to support file screening."
"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 management graphical interface needs more improvement."
"The interface look and feel could be improved."
"The system currently has a 15TB LUN size limit and that snapshots need to be scheduled through script API instead of the GUI."
"Some of the nice to haves for us, in terms of today, would be VVols but again, it’s not a critical feature."
"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."
"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 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."
"I think it needs to be more cost-effective. I would also say that even though the capacity is good, there is also room for improvement there. Also, they could improve the security of the system."
"There's already a concern with VMware with ransomware and security issues. VMware could focus on improving security."
"Ease of administration is one area where vSAN could be improved."
"This solution could be improved by having more than one controller for the environment. VMware depends on one controller for the whole environment, whereas Nutanix has one controller for each node. Because there is only one controller with VMware, if there was any drop, then the whole environment would stop working. In Nutanix, I have five nodes—there is one controller for each node and it depends on a virtual controller—so if the controller of any node is down, the whole environment will still work."
"The platform’s pricing needs improvement. Additionally, there should be an appliance module included in it."
"I am looking for more of a software-defined storage platform that uses different protocols, such as iSCSI, NFS, and CIS, and maybe also has an object as part of that. They should 100% make it more of a storage-based product where it is not linked just to VMware, and it also has NFS and iSCSI built-in at a scalable level. They should turn it more into a dedicated storage-as-a-service platform instead of just being built into the VMware kernel. Their level one and level two support is not at all good, and it should be improved."
"The upgrading process could be simplified."
"The usability is pretty good but it could use a little tweaking on the UI, with a clearer definition of exactly what some of the things do."
