Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."Their technical support is excellent. It's the best out of any of the vendors we work with."
"The solution is very reliable."
"They have really good baked in analytics to show you trends for growth history, so it does help with future planning for data growth."
"The data reduction technology part of the scalability has been impressive, like its ability to host additional workloads, volumes of data, and databases."
"The stability of Pure Storage is very very good."
"The most valuable features are extremely low latency, high IOPS with VMware, inline deduplication and compression."
"It helps to simplify storage. For most of our customers, when they move to Pure Storage, storage becomes an afterthought."
"The most valuable feature is its speed."
"IBM FlashSystem is a powerful effective storage solution. Additionally, it is user-friendly, anyone can use it."
"The most crucial feature of IBM FlashSystem is compression."
"Flash disk with Easy Tier option"
"The performance is very good and we use this product to enhance our core system."
"The valuable features for us are the extra add-ons, such as the FIM provisioning, the compression, the disaster recovery capabilities, and the storage pooling functions."
"The compression and deduplication features are the most valuable."
"High availability and enhanced security; Proven dependability; Data compression with hardware acceleration; Advanced copy services features are all in this product."
"IBM FlashSystem is the best solution for storage virtualization."
"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 setup needs to be improved the most. They can do a little more with the user interface, but the setup is what I would like to see made a bit easier."
"The one major gripe I have is that there is no snapshotting enabled by default on the SAN."
"We haven't seen ROI yet."
"With scalability, I have run into a little problem with our last upgrade. There were some undocumented limitations to the number of drives that our controller could run on. So, instead of putting in a new data pack as we had anticipated, we had to keep adding and removing to get up to the capacity that we needed to be. What should have been a one day process (or a few hours) turned into a month and a half process."
"There was some complexity in the initial setup."
"Going forward, don't complicate things for the customers."
"We haven't seen ROI."
"We understand that they're thinking about it, but one of the things that would be nice is if they added some basic file-level capabilities to the platform. The idea is that they would run a basic NFS or CIF share from the controllers. FlashBlade is the powerhouse for File and Object storage, but if you don't need all that power, a lightweight file function would make FlashArrays more versatile."
"The solution has a low number of NVME host attachments at 16 per IO group over the fiber channel."
"The Data Reduction Pools (DRP) support could be better."
"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."
"Additional licenses might be added for the fundamental licenses, such as those for copying and flash copies."
"Include an option to upload the support package to the IBM ECuRep when opening an IBM PMR."
"Their technical support needs improvement in terms of reachability for the clients and response times. They should be more responsive and have more online platforms for support. They should make more technical information available online. There could be some kind of documentation community."
"When you provision a datastore auto-format takes a long time"
"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."
