Offers high performance and dependable support for fast storage needs
The most valuable feature of IBM FlashSystem is its robust back code. When integrated properly into the environment and configured according to the guidelines, it provides a very solid infrastructure that does the job on demand. Additionally, IBM FlashSystem offers competitive pricing and reliable performance. The hardware is dependable, ensuring that it functions effectively when the setup is done correctly.

Good value for money but issues with modular scaling
IBM XIV's most valuable features are NVME, especially when it comes to de-duplication, compression, and responsiveness I've been using IBM XIV for two and a half years. IBM XIV is stable. IBM XIV's scalability is adequate for our requirements, but because it's modular, you can't scale to larger…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It was quite easy to migrate from EMC storage because everything is virtualized."
"IBM FlashSystem is a powerful effective storage solution. Additionally, it is user-friendly, anyone can use it."
"The most valuable feature of the solution is compression."
"The cost was low when we purchased it."
"The maintenance service and support from IBM is very good."
"High availability and enhanced security; Proven dependability; Data compression with hardware acceleration; Advanced copy services features are all in this product."
"When it comes to the interface of the solution we did not encounter any challenges. Additionally, the solution has good documentation."
"Data deduplication is one of the most valuable features of this solution."
"The XIVs here are only being used for non-production and dev systems, but still the performance and robustness of the systems are very good."
"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."
"The performance and robustness of the systems are very good."
"Implementing Remote mirroring and local Snaps is very easy."
"For us, the XIV is pretty much set-it-and-forget-it storage."
"The product is exceptionally reliable and very easy to manage."
"IBM XIV's most valuable features are NVME, especially when it comes to de-duplication, compression, and responsiveness."
 

Cons

"The storage size vs the storage price needs to improve."
"The interface could improve in IBM FlashSystem."
"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."
"Support is horrible. It takes weeks to get simple answers."
"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."
"Customization features must be improved."
"The GUI for monitoring performance metrics could provide better visibility. For example, it doesn't let me segregate the IOPS per volume."
"They can improve its initial configuration. The initial configuration is currently very difficult."
"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."
"The change form synchronous mirroring to asynchronous (and vice versa) without reconfiguration from scratch would be helpful."
"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 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."
"Management accessibility. Both the GUI and the CLI require installation of a Java-based thick client, which is ridiculous, plus a drain on resources."
"IBM XIV's scalability is adequate for our requirements, but because it's modular, you can't scale to larger requirements."
"Until the drive is replaced, the pool_resizing is locked."
 

Pricing and Cost Advice

"IBM V7000 has a new license and price structure which provides intuitive licensing based on the functions customers wish to enable and use the most."
"I would rate the pricing of this solution a four out of five."
"The price depends of the technology that our customers need. The price can come at a lower cost but this may increase as storage is added."
"Its price is very good."
"The integration is already included in the license cost of IBM FlashSystem. The integration is very easy. You get the IBM storage core with all software, firmware, and upgrades. EMC provides the features in the box, but they are not free for customers. There is a licensing cost for features. We have yearly licensing, but IBM has also provided a new option where you pay as you go. They provide a big box, and I pay, for example, for 10 terabytes. If I exceed 10 terabytes, IBM will charge for the new storage after 10 terabytes. It is a good opportunity in the market for using the storage as a cloud and paying as you go."
"This is an expensive product and if the price were reduced it would be better."
"Our customers would like IMB FlashSystem to be less expensive."
"This solution is expensive compared to other solutions."
"If you are going to use the product behind an SVC, IBM will price the units lower, since you are likely not to use any of the advanced copy services."
"We have a five-year total cost of ownership where we pay an initial amount and then annually for maintenance."
"Licensing is straightforward."
"No-license-required policy, unlike others where you need a license for everything. Just pay once and forget about licenses."
