We performed a comparison between IBM FlashSystem and IBM XIV based on real PeerSpot user reviews.
Find out in this report how the two Modular SAN (Storage Area Network) solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."Speed (IOPS/second) – It is most vital for applications that need low latency and high speed for transferring the data."
"The most valuable features are deduplication and compression."
"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 initial customer technical support was efficient and effective."
"The speed of the unit is its best feature. It performs very well."
"The speed and the ease of installation are the most valuable features."
"The price-performance ratio is most valuable."
"The most valuable features in IBM FlashSystem are IOPS, performance, duplication, and compression."
"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."
"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."
"Installation is amazingly easy."
"Hands down, this is the easiest storage platform on the market to manage."
"The support could improve by allowing you to speak to someone when you call rather than them calling you back. However, once we do have contact with one of their technicians they are excellent."
"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."
"I would like to see bigger modules."
"The storage capacity of this solution could be improved."
"The solution's infrastructure technology level could be PCI Express 5 instead of PCI Express 4 for the next version."
"The price is very costly."
"Include an option to upload the support package to the IBM ECuRep when opening an IBM PMR."
"It could be easier to implement."
"I would rather have a web GUI served directly from the unit, and a CLI accessible directly through SSH."
"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."
"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 XIV's scalability is adequate for our requirements, but because it's modular, you can't scale to larger requirements."
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, Hitachi Virtual Storage Platform, Dell Unity XT and NetApp AFF, whereas IBM XIV is most compared with .
