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 ease of use. That's what our customers love. They say it's very easy, they don't need special training, they don't need to call us or any other company or integrator to help them do their job. That's the main reason they purchase Pure."
"The predictive performance analytics are good."
"The most valuable feature of Pure Storage FlashArray is the complete set of functions it provides."
"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."
"I like its speed. It has all the features that I need."
"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 solution offers amazing performance."
"The all-flash disc is the most valuable feature of this solution."
"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."
"The speed and, for us in particular in what we're doing, the data de-duplication."
"It provides a full feature set without separate licensing (deduplication, compression, snapshot, asynchronous replication, stable performance, etc.)."
"The most valuable aspect is the use of solid-state storage drives instead of spinning drives."
"The increased performance is many times above our previous array performance in all metrics. Integration with vSphere features is also a definite plus."
"The capacity that we're saving by using Kaminario's K2 is giving us a four-to-one ratio for our deduplication."
"Data reduction and snapshot abilities: Smaller footprint in the datacenter (lower cost for power, cooling, etc.)."
"Scale out is a differentiator for them, especially in the enterprise market. It's key for a lot of customers."
"I like the tolerance of VMware vSAN."
"I like that we could choose whatever hardware we wanted, rather than having to use one particular vendor."
"We have found the solution to be very scalable."
"Scalability in vSAN has been really good. It's very easy to add nodes in, to automatically generate the drives and the disk groups. It has been a piece of cake, surprisingly so."
"If we decide to expand, vSAN could offer us some flexibility. We are researching ways to set this up from a new data center, which is located somewhere different from the current location right now."
"The implementation is simple, it was very straightforward. It took us approximately three weeks because it was installed in four locations."
"It has a single pane of glass for management and operational control, which is the most valuable feature. The integrated storage is also valuable."
"I have found the solution to be scalable."
"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."
"Just some nit picky stuff, like allowing servers and volumes to be grouped. Therefore, it would easier to work with them in the GUI."
"Had some issues with Purity not being entirely compatible with VMware ESXi."
"I would like to get a weekly report of how our storage has been used, and if there is any storage sitting there not being used."
"It's not so scalable. It's got moderate scaling capabilities right now. The clustering technology needs a bit of work, they need to improve that."
"I would like to see support for NVMe, end-to-end."
"I'd like to see a move towards individual VMs for what the performance of each VM is in a VD infrastructure. I can see the overall volume, but I would love to see things in a more granular level on the VM side."
"The one major gripe I have is that there is no snapshotting enabled by default on the SAN."
"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."
"Access to technical support should be improved for our region. Technical support is good, but they're very hard to access."
"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."
"The interface look and feel could be improved."
"A single pane of glass to monitor/manage multiple arrays would be helpful."
"The front panel of the drive shelf doesn't always seat firmly."
"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."
"If we have some complicated issues, you have to use the command lines interface. Not everything is possible to be fixed in the GUI. This is a drawback, that some things have to be fixed via command-line interface and should be able to be done in the GUI."
"It doesn't seem like it gives the performance that an actual SAN would give for heavy IOPS, read/writes."
"Its installation should be easier, and its price should be cheaper. It would be good for the product if they can include the data locality feature."
"Based on my testing, I would like to expand deduplication to include hybrid deployments and not just for all-flash deployments."
"When you upgrade the vSAN, there are some issues like lost data and problems with the log. The log disappears. When you upgrade the solution, you must have several logs, so if you have some problems, you can check the log server to find them."
"This product is very expensive."
"There is a lot that VMware could improve from a marketing perspective. The cloud is still new for many people, so extending storage should be effortless. It shouldn't be so complicated to extend the storage so workloads can access it no matter where they go."
"It needs to be vanilla. There shouldn't be any custom drivers, any custom anything. It should just be, "Hey, you know what? These drivers are going to work for this version, the next version, and the following version after that." That's the difficulty in this. It takes too much upkeep... The main issue is drivers. Every time we move to a new vSAN version, we're having problems finding the correct drivers for the vendor."
