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 most valuable feature of this solution is the support."
"The product cheaper compared to other solutions concerning the technology that they are using."
"The performance is very good."
"They are quite responsive and our local team was pretty good."
"The back-end data reporting for Pure Storage is phenomenal. The data that you can see on the performance of your customers' array, so you can be proactive about upgrades or enhancements, and is a phenomenal tool to have access to as a partner. I haven't seen this type of stuff out of anything of the other storage systems."
"It's very fast and very easy to use. It performs well and is both flexible and compatible. We like it because it's easy to use."
"It simplifies the overall management. We don't have to worry about storage anymore."
"The solution helps to simplify storage."
"IBM FlashSystem is flexible, quick, and has a solid design."
"IBM FlashSystem is the best solution for storage virtualization."
"The FlashSystem 900 consistently delivers performance below 1ms for read/write. This performance is essential for an effective SVC stretch-cluster configuration across two datacenters, and presenting active-active storage to the customer."
"Data deduplication is one of the most valuable features of this solution."
"Most of the features for the reduction in data compression are useful. It is also very easy to use and administer. Its performance is also good."
"The most valuable features in IBM FlashSystem are IOPS, performance, duplication, and compression."
"Flash disk with Easy Tier option"
"The GUI is very easy and performance is also good."
"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 cloud support, which we know is coming, although it's not out yet. It's going to be released in the next versions. That would be the biggest win, if additional cloud support is built into the array."
"In the configuration, which we brought in or tested it in, it has a very limited config as far as the array goes. That said, it still did more than our anticipation."
"They are doing some stuff with containers and an object search. These could be improved, because containers is one of the main topics that we are talking with our customers about."
"A three wave application or multi wave application synchronization would be an improvement."
"The support for NFS protocols right out-of-the-box need improvement. I'm used to other storage vendors who have NFS support right out-of-the-box, and Pure Storage doesn't seem to have anything."
"The connectivity needs improvement. You do not have the possibility to have a file and block connectivity at the same time on the same machine. It has limited ability to do so."
"It goes at about 95 percent, so we have had some performance issues. It is hard to clear them."
"I want to learn more about command line usage which I have not explored much yet. However, there are many automated solutions for repetitive tasks. I would like to see additional features like performance monitoring, configuring of alerts, and the customization of alert thresholds in the next release."
"The solution has a low number of NVME host attachments at 16 per IO group over the fiber channel."
"IBM could do more marketing and improve brand awareness. I had never heard of this product until a colleague told me about it. FlashSystem could add a few features, but it would probably increase the price. For example, Pure Storage offers instant snapshotting and partitioning. That would be nice to have, but I think the cost would go up."
"I know they have a flashcopy manager, but it is extra software, an additional license, and some customers don't like to add addition costs to their infrastructure. If IBM could create, or include snapshot management within the GUI, that would really be helpful."
"I would like to have a larger disk. Right now, you can get 57 terabytes in a shelf. Once they get the larger disk and you get larger capacities, it'll be even better."
"It is slightly more expensive, however, it all depends on your supplier."
"Enterprise data storage needs improvement. They should create a feature for data and file storage."
"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 generic functionality of IBM FlashSystem, IBM always dismisses using file share or sharing protocols inside their storage hardware, and they only focus on the block-level storage."
"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."
