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."The solution is scalable."
"The latency is good."
"The most valuable feature of this solution is its ease of use."
"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 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."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"IBM's technical support do excellent work."
"High availability and enhanced security; Proven dependability; Data compression with hardware acceleration; Advanced copy services features are all in this product."
"The most valuable feature is reliability."
"The compression and deduplication features are the most valuable."
"The technical support for this solution is good. They used to help us when the motherboard of Power Systems broke. Their response times are really fast."
"User friendly management interface."
"The installation is nice and easy."
"The feature I find most valuable, is the deduplication, because the nature of the data that we are using in our current environment, has a lot of replicated data."
"The solution is useful for machine learning and scientific applications, including computer simulations."
"This has been one of the most reliable storage systems that I have ever used."
"The tool's pricing is higher than competitors."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"The software layer has to improve."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."
"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."
"The pricing needs to be more competitive."
"The design is a little old-fashioned and could be updated. The rack is very primitive and designed in an older style."
"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?"
"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."
"The array level RAID does not seem available."
"IBM should improve its data reduction development."
"Enterprise data storage needs improvement. They should create a feature for data and file storage."
"The solution is not easy to use and could improve."
"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."
IBM FlashSystem is ranked 6th in All-Flash Storage with 106 reviews while VAST Data is ranked 18th in All-Flash Storage with 2 reviews. IBM FlashSystem is rated 8.2, while VAST Data is rated 10.0. The top reviewer of IBM FlashSystem writes "An easy GUI and simple provisioning but our model does not support compression". On the other hand, the top reviewer of VAST Data writes "Stability-wise, a device that has been up and running for years". IBM FlashSystem is most compared with Dell PowerStore, Pure Storage FlashArray, Dell Unity XT, NetApp AFF and Hitachi Virtual Storage Platform, whereas VAST Data is most compared with Pure Storage FlashBlade, NetApp AFF, Pure Storage FlashArray, Qumulo and Dell PowerScale (Isilon).
