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

"The most valuable features of IBM FlashSystem are performance and security."
"Something that historically had been hard and difficult became a background task, once the old array was managed by the V7000."
"The solution is scalable and has varying degrees of scalability."
"The stability of the product is very valuable."
"One of the valuable features is the performance, it is one of the best in the market."
"The IBM System is top-notch and offers all the features we need to keep going for another 5 years."
"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."
"The most valuable feature of the solution is SCM (Storage Class Memory), which has the lowest latency value in the storage industry."
"IBM XIV's most valuable features are NVME, especially when it comes to de-duplication, compression, and responsiveness."
"Installation is amazingly easy."
"The performance and robustness of the systems are very good."
"For us, the XIV is pretty much set-it-and-forget-it storage."
"Implementing Remote mirroring and local Snaps is very easy."
"Hands down, this is the easiest storage platform on the market to manage."
"The product is exceptionally reliable and very easy to manage."
"IBM XIV is attractive because it gives value for money in terms of features."
 

Cons

"It is slightly more expensive, however, it all depends on your supplier."
"A big area for improvement is that the data reduction pool feature is not recommended for use in a production environment because it has stability and performance issues."
"One area for improvement is in the GUI, where host clusters are not properly dealt with. With Hypervisor host clusters, all hosts must see the same volumes in the same order. Using the concept of a “host-group” has been around (even with IBM) for many years, so why not with the V7000?"
"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."
"At the beginning of every year, IBM releases firmware. When I find any bugs in the firmware during the year, I am unable to find any information from IBM regarding the bug."
"They can improve its initial configuration. The initial configuration is currently very difficult."
"Support is horrible. It takes weeks to get simple answers."
"The design is a little old-fashioned and could be updated."
"Until the drive is replaced, the pool_resizing is locked. This has been an issue a lot of times, especially when the contract says IBM will not replace disks until three drives fail."
"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."
"I guess we'd like to see the XIV keep pace with how storage is going in terms of speed and latency."
"IBM XIV's scalability is adequate for our requirements, but because it's modular, you can't scale to larger requirements."
"IBM XIV's scalability is adequate for our requirements, but because it's modular, you can't scale to larger requirements."
"The change form synchronous mirroring to asynchronous (and vice versa) without reconfiguration from scratch would be helpful."
"I would rather have a web GUI served directly from the unit, and a CLI accessible directly through SSH."
 

Pricing and Cost Advice

"The solution has good pricing, but it is not cheaper."
"Its price is very good."
"You purchase it as a bundle and the price is comparable."
"The cost is pretty high in terms of licensing. We pay at least $100,000 USD in licensing fees for the storage."
"Regarding licensing make sure you add at least three years software maintenance from IBM at the beginning, because you will not be able to download firmware updates or any fixes/patches without this."
"Our customers would like IMB FlashSystem to be less expensive."
"I would rate the pricing of this solution a four out of five."
"The price of IBM FlashSystem is reasonable."
"Licensing is straightforward."
"We have a five-year total cost of ownership where we pay an initial amount and then annually for maintenance."
"No-license-required policy, unlike others where you need a license for everything. Just pay once and forget about licenses."
"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."
