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."For us, the most valuable feature is the compression and deduplication. Being able to deploy a three to one ratio for storage is absolutely critical in today's world with the growing need for storage and the growing need for more space."
"It is an SSD array that has awesome performance, low submillisecond latency, and does what it is supposed to do. It just works, which is difficult for things to do anymore."
"It reduces space and the polar consumption. It also accelerates the application."
"As soon as we introduced our first Pure Storage FlashArray, the first benefit was at least twice the performance increase. Our production databases simply ran twice as fast with no other change."
"It simplifies building out the storage."
"Their technical support is excellent. It's the best out of any of the vendors we work with."
"The solution helps to simplify storage."
"The tool has reduced our power consumption."
"The speed and, for us in particular in what we're doing, the data de-duplication."
"The capacity that we're saving by using Kaminario's K2 is giving us a four-to-one ratio for our deduplication."
"Inline compression"
"The most valuable feature is definitely the always-on data deduplication."
"Data reduction and snapshot abilities: Smaller footprint in the datacenter (lower cost for power, cooling, etc.)."
"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."
"Scale out is a differentiator for them, especially in the enterprise market. It's key for a lot of customers."
"The solution fits well with my requirements."
"There is not a lot of maintenance required."
"One of the most valuable features of this solution is that it is stable."
"The lower skill cost of maintaining it meant that we could do more with the people that we had."
"The product’s most valuable features are performance and expandability."
"Flexibility, growth, and expansion are probably the more important features for us. As our environment grows, the more users come on, the more VDI workstations that we need, we can easily expand either horizontally or vertically with the environment"
"I like vSAN because they release features incrementally, every year, and you don't have to upgrade your hardware to get those features. If you bought a traditional SAN, you would have to upgrade your hardware constantly, every three years: You would get it, and it is how it is for three years. But on vSAN, you upgrade when you have to, when your hardware gets old or when you need more capacity. It's great, you get new features constantly."
"it's easy to scale, it's easy to predict IOP needs, and you can design for low latency using all-flash... Also, for setting up new clusters for VDI quickly, it's nice. You don't have to wait on an order for a storage vendor to ship you a system and help you configure it, you do it all yourself. And the sizing guides are pretty straightforward."
"It is a bit expensive."
"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."
"I would like to see the NAS add-on component become more fault-tolerant than just a single virtual machine running inside the array. I'm unwilling to use it for that reason."
"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."
"This product has only two active controllers, whereas other solutions can have more. This is something that needs to improve."
"It needs to improve its price."
"Larger capacity and more storage ports would be the two things I'd like to see."
"I would like to see some improvements on the FlashBlade side around the CIFS space support. I am not super familiar with all the different NAS protocols that they run on their box, but there could be some improvements made on SMB CIFS side."
"A single pane of glass to monitor/manage multiple arrays would be helpful."
"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 like them to improve the look of the product’s external casing and shelves."
"The front panel of the drive shelf doesn't always seat firmly."
"Some of the nice to haves for us, in terms of today, would be VVols but again, it’s not a critical feature."
"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 like compression and deduplication to be offered for offloading hardware, instead of doing it with software. That would be nice."
"The UI could certainly be better. The inside into what's actually going on with vSAN would be nice to know."
"While I like the replication and compression features, there is a problem with them running too slowly."
"It is an expensive solution."
"I see room for improvement with vSAN in particularly in the reporting realm. Now, with vSAN 6.7, they're starting to include vRealize Operations components in the vSphere Client, even if you're not a vRealize Operations customer. So, that's really good. It exposes some really low-level reporting. I would like to see more of that. However, you have to be a vRealize Operations customer to obtain that. I would like to see more include of this included in the vSAN licensing."
"Ease of administration is one area where vSAN could be improved."
"The architecture of vSAN is not good. vSAN works with objects, such as disks, and it causes problems with availability."
"It should be easier to use."
