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."It upgrades in place which means we'll be using it well into the future."
"Having fast storage allows actual servers to perform in high capacity so we don't have slowdowns on our applications."
"The initial setup is very straightforward. You simply plug it in and turn it on."
"The speed of the Pure FlashArray is very, very fast and nothing in the market can compare to it."
"It helps to simplify storage. For most of our customers, when they move to Pure Storage, storage becomes an afterthought."
"We've been using FlashArray's snapshot for backups. Their replication across sites and response time are also excellent."
"We have seen savings in our storage. The speed of deployment has gone from several days to a few minutes. This product has reduced that time into minutes, simplifying storage for us."
"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."
"Inline compression"
"The ratio between the physical storage and the storage we use is very high."
"It provides a full feature set without separate licensing (deduplication, compression, snapshot, asynchronous replication, stable performance, etc.)."
"Implementation of the solution is very simple."
"Latency is definitely the big key for us."
"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 increased performance is many times above our previous array performance in all metrics. Integration with vSphere features is also a definite plus."
"Built-in snapshot support gives us SAN-side functionality most other platforms would have had us license separately."
"It is easier to deploy than the traditional SAN."
"vSAN is one of the easiest implementations of any VMware product. It's almost like click it to enable it, then you're almost done."
"The solution fits well with my requirements."
"The features of vSAN allow us to reduce our operational complexity to a large degree."
"It is easy to work with, easy to handle, and easy to manage."
"One of the most valuable features of this solution is that it is stable."
"We are finding that vSAN is a lot more scalable and adaptable, because we can go in with hybrid arrays for our lower-end storage needs or with all-flash versions of vSAN for places where we need more performance, and it's coming in at a lower cost point than an actual traditional array."
"The performance has exceeded our expectations and exceeded our traditional converged infrastructure."
"I had to contact customer support when a drive failed as I was doing a couple of OS upgrades."
"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."
"In some cases, we get into very in-depth conversations around movement of specific data and, what's more, chunk sizes. The documentation lacked any description or information on that."
"I recognize it's a difficult challenge, but I would like to see them make the pricing more reasonable."
"If they could make it cheaper, that would be something."
"The way Pure Storage does the controller storage warranty or replacement has been an issue for some people who just replace the controllers every couple of years, and that's where some of the confusion with pricing and support has come in. They should be clear on the way the controller replacements happen, as it is important to know whether or not you can get a good return on them, because it can be a little confusing."
"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."
"The initial setup was a little complex. We had some initial issues with the design and had to help correct some of the white papers for it, but it wasn't your standard use case."
"The front panel of the drive shelf doesn't always seat firmly."
"I would like them to improve the look of the product’s external casing and shelves."
"Access to technical support should be improved for our region. Technical support is good, but they're very hard to access."
"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."
"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."
"The interface look and feel could be improved."
"Some of the nice to haves for us, in terms of today, would be VVols but again, it’s not a critical feature."
"The platform's cost affects the business. This particular area needs improvement."
"I would love to see vSAN integrate Persistent Memory and NVDIMMs. I know they're supposed to be working on an elastic tier so that we don't have the issues with destaging from the cache to the capacity. Those are the things that I'm interested in."
"The solution could maybe improve failure protection."
"It is a memory intensive app."
"The server files are larger than before."
"Better options would be clustered nodes, or even cloud configuration. There is room for improvement in cloud configuration, we typically do web browsing for management."
"The only thing I can think of at this time is to improve the performance monitoring and performance visibility within the GUI."
"I would like to see more support for applications. I think currently it only supports applications between two vSAN clusters."
