We performed a comparison between IBM FlashSystem and Kaminario K2 [EOL] 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 first year, we started out with one or five terabytes and it took what was 20 terabytes of storage down to less than one terabyte."
"Pure Storage FlashArray's overall speed is its most valuable feature."
"The scalability options are very nice because you can scale it much better and faster. The scalability was there in the previous environment also, but this is far better than what we had before. It basically helps the user in case they are looking for more storage. We can scale it much faster."
"The most valuable feature is it never goes down. We can expand and create volumes."
"We can store more for a cheaper price as opposed to paying for larger devices and larger rack spaces which get outdated sooner and which we'd have to change every two years. It simplifies storage for us."
"I never have to worry about its performance or if it is the root cause of an issue."
"Non-disruptive upgrades: You can upgrade at anytime without worry."
"The console is simple to use. It has good performance. It is easy to install, understand, and manage, with a good ratio of deduplication and compression. It is doing its job."
"When it comes to the interface of the solution we did not encounter any challenges. Additionally, the solution has good documentation."
"We are a 100% satisfied with the stability of the solution."
"The ability to create LUNs and modify them are the most valuable features of this solution."
"The initial setup was really straightforward. It was not complex. Deployment took one month, due to the data migration duration."
"The initial customer technical support was efficient and effective."
"The most valuable feature in demand is virtualization and its support storage of virtualization features."
"The most valuable feature of the solution is SCM (Storage Class Memory), which has the lowest latency value in the storage industry."
"FlashSystem offers proven technology in a compact package."
"Latency is definitely the big key for us."
"The capacity that we're saving by using Kaminario's K2 is giving us a four-to-one ratio for our deduplication."
"The speed and, for us in particular in what we're doing, the data de-duplication."
"Data reduction and snapshot abilities: Smaller footprint in the datacenter (lower cost for power, cooling, etc.)."
"The GUI is very straightforward and easy to use."
"Logic/software management"
"The increased performance is many times above our previous array performance in all metrics. Integration with vSphere features is also a definite plus."
"Inline compression"
"If we suddenly dump large amounts of data onto the storage system, it takes a while to process it."
"There are a lot of things to improve."
"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 have an easy way to determine the cost per VM so that I can present a solution to our customers."
"Pure Storage FlashArray could improve by being more secure."
"Data reduction is an area that needs improvement. There is a garbage collection service that runs but during that time, system utilization increases."
"The solution is not cheap."
"Having something native in the Pure Storage ecosystem would make it integrated and in one single company, and we wouldn't have to work with multiple organizations."
"Replication features need improvement. Currently, they are there in the product, but I'm not sure as to how it works exactly."
"The data reduction pool feature sucks and is not recommended for use with heavy workloads."
"Our model does not support compression or deduplication."
"Events/log analysis tools."
"Product support is restricted to IBM only. It must be decentralized to IBM partners as well."
"The support could improve by allowing you to speak to someone when you call rather than them calling you back. However, once we do have contact with one of their technicians they are excellent."
"They can improve its initial configuration. The initial configuration is currently very difficult. There are multiple choices or alternative ways to configure based on the use case and what you are targeting out of the device, that is, more capacity or more performance. These multiple alternatives cause a lot of confusion. They should increase the processing part of the nodes. Currently, you can cluster up to eight nodes. From my experience and the workload that I am facing in my environment currently, I would like to see either a bigger or stronger node or a larger number of nodes that can be clustered together. We formally communicated to them that we need to see either this or that, and they are working on something."
"The Data Reduction Pools (DRP) support could be better."
"A single pane of glass to monitor/manage multiple arrays would be helpful."
"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."
"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 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."
"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 them to improve the look of the product’s external casing and shelves."
