We performed a comparison between IBM FlashSystem and IBM XIV based on real PeerSpot user reviews.
Find out what your peers are saying about NetApp, IBM, Hewlett Packard Enterprise and others in Modular SAN (Storage Area Network)."The installation is nice and easy."
"IBM's technical support do excellent work."
"IBM FlashSystem has an easy to use GUI, similar to the IBM Storewize family, which make it one of the best flash storage systems in the market."
"IBM FlashSystem is flexible, quick, and has a solid design."
"The most valuable features were the performance of the array, i.e., very low latency and high IOPS. Plus, the management interface is very easy to use."
"This solution is very stable."
"The ability to create LUNs and modify them are the most valuable features of this solution."
"The solution is very easy to configure and use."
"As it spreads, a chuck of 1MB across the board means using all available spindles on the backend."
"The performance and robustness of the systems are very good."
"IBM XIV's most valuable features are NVME, especially when it comes to de-duplication, compression, and responsiveness."
"Very easy to produce reporting data (Snaps). Very easy and fast for provisioning devices and Remote mirroring."
"Hands down, this is the easiest storage platform on the market to manage."
"Installation is amazingly easy."
"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."
"Enterprise data storage needs improvement. They should create a feature for data and file storage."
"The solution is quite expensive. That's one of the downsides to using it."
"Replication features need improvement. Currently, they are there in the product, but I'm not sure as to how it works exactly."
"The pricing needs to be more competitive."
"GUI interface should be enhanced more as there is some issues in copy services."
"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."
"The solution's infrastructure technology level could be PCI Express 5 instead of PCI Express 4 for the next version."
"IBM XIV's scalability is adequate for our requirements, but because it's modular, you can't scale to larger requirements."
"I encountered stability (performance) issues during enclosure or disk rebuild. Also some power supply issues due to malfunctions of circuits. Sometimes "internal" Snap sessions hang and consume pool capacity."
"I would rather have a web GUI served directly from the unit, and a CLI accessible directly through SSH."
"The change form synchronous mirroring to asynchronous (and vice versa) without reconfiguration from scratch would be helpful."
"Until the drive is replaced, the pool_resizing is locked."
"This product was not a good fit for our organization as we have a ton of latency sensitive applications and XIV was not able to keep up with IO + latency demand."
IBM FlashSystem is ranked 2nd in Modular SAN (Storage Area Network) with 106 reviews while IBM XIV is ranked 10th in Modular SAN (Storage Area Network) with 6 reviews. IBM FlashSystem is rated 8.2, while IBM XIV is rated 7.6. 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 IBM XIV writes "Using it behind the SAN volume controller, latency is predictable and it is reliable". IBM FlashSystem is most compared with Dell PowerStore, Pure Storage FlashArray, NetApp AFF, Dell Unity XT and Hitachi Virtual Storage Platform, whereas IBM XIV is most compared with .
