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 all-flash storage has tier replication capabilities."
"Virtualization of external storage, while adding cache and speed to the external storage."
"IBM FlashSystem is the best solution for storage virtualization."
"We are a 100% satisfied with the stability of the solution."
"Installing FlashSystem is very easy. It takes less than half an hour, and I can handle it all myself."
"The most crucial feature of IBM FlashSystem is compression."
"IBM's technical support do excellent work."
"The most valuable feature of the solution is compression."
"As it spreads, a chuck of 1MB across the board means using all available spindles on the backend."
"Hands down, this is the easiest storage platform on the market to manage."
"Installation is amazingly easy."
"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."
"The performance and robustness of the systems are very good."
"Customization features must be improved."
"AHV is Acropolis Hypervisor – A relatively new Hypervisor, robust and stable as VMware vSphere, has built-in advanced analytics and powerful operations, Self Service Portal and components for DevOps included, managed by a single pane of glass (Prism) via HTML5 and it is free of charge – That is why Nutanix is so advanced and revolutionary."
"I have looked at a few pages of a report I download and I saw a graph there regarding software-defined vendors. IBM is not in a good position on this graph. I know that they are working very hard on this, to make it much better and to get to a level where it's not only hardware but also software to provide a complete solution."
"IBM FlashSystems is lagging in optimizing storage technologies."
"The product needs to improve their scalability."
"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."
"We had issues when attempting to do a flash, we hope to resolve it soon."
"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 change form synchronous mirroring to asynchronous (and vice versa) without reconfiguration from scratch would be helpful."
"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."
"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."
"Until the drive is replaced, the pool_resizing is locked."
"IBM XIV's scalability is adequate for our requirements, but because it's modular, you can't scale to larger requirements."
"I would rather have a web GUI served directly from the unit, and a CLI accessible directly through SSH."
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, Dell Unity XT, NetApp AFF and Hitachi Virtual Storage Platform, whereas IBM XIV is most compared with .
