We performed a comparison between IBM FlashSystem and VAST Data 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 has benefited my organization because it has reduced time to insights."
"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."
"The solution is scalable."
"The solution is very straightforward to set up."
"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."
"It has good, reliable, fast storage."
"The most valuable features of this solution are its ease of use and performance."
"What I really like about this program, is that it is easy to use and easy to configurate."
"The solution is scalable and has varying degrees of scalability."
"The performance of the All-Flash System is very good. There is more enhanced performance and data production in the solution, which I appreciate."
"Flash disk with Easy Tier option"
"One of the most valuable features is that it's very easy to use and configure. It used to be more difficult, but now it's almost flawless."
"The all-flash storage has tier replication capabilities."
"The performance is very good and we use this product to enhance our core system."
"IBM FlashSystem is a stable solution."
"The speed of the unit is its best feature. It performs very well."
"This has been one of the most reliable storage systems that I have ever used."
"The solution is useful for machine learning and scientific applications, including computer simulations."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"The software layer has to improve."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."
"I would like to see replication and DR features in the next release of this solution."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."
"The tool's pricing is higher than competitors."
"The solution is not easy to use and could improve."
"I think the only thing the developers can look at, is that it is limited to 25 gigabytes currently. In the next release they might want to increase that."
"The only issue my team faced was transferring the data from the old system to IBM FlashSystem, which is an area for improvement in the solution."
"One area for improvement is in the GUI, where host clusters are not properly dealt with. With Hypervisor host clusters, all hosts must see the same volumes in the same order. Using the concept of a “host-group” has been around (even with IBM) for many years, so why not with the V7000?"
"There could be some extra features added."
"Sometimes the performance is effective but it gets resolved in the process."
"I have looked at a few pages of a report I download and I saw a graph there regarding software-defined vendors. IBM is not in a good position on this graph. I know that they are working very hard on this, to make it much better and to get to a level where it's not only hardware but also software to provide a complete solution."
"The pricing could be improved, but I think it's getting better and better with each version. IBM needs to implement NAS storage again, as this is a big flaw. Dell EMC is very good at this and if you compared them based on NAS storage, Dell EMC would win right away. IBM's solution for NAS storage is very complicated. We don't have a storage box that provides file sharing from itself, we have to put software on it and go through a whole complicated process. It should be simplified."
"The write performance could be improved because it is less than half of the read performance."
"The read/write ratio is an area in the solution with some flaws and needs improvement."
