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

"IBM FlashSystem is flexible, quick, and has a solid design."
"If you have the funds and you require speed, this product is the answer."
"The speed, performance, and stability are the best features of IBM FlashSystem."
"The performance of IBM FlashSystem is very good. The new technology and high throughput have given us more confidence in the solution. The management of the system has improved and we can control the monitoring system alerts and multiple FlashSystems with the Enterprise Cloud Edition, which is free. The migration of recently stored data to a new flash is much easier. You can move your data because you can utilize it externally."
"The most valuable features are, of course, the virtualization of the storage, the performance, and the compression."
"The stability of the product is very valuable."
"We've found the solution to be very stable so far."
"The performance is very good and we use this product to enhance our core system."
"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."
"Hands down, this is the easiest storage platform on the market to manage."
"As it spreads, a chuck of 1MB across the board means using all available spindles on the backend."
"For us, the XIV is pretty much set-it-and-forget-it storage."
"Installation is amazingly easy."
"Very easy to produce reporting data (Snaps). Very easy and fast for provisioning devices and Remote mirroring."
"IBM XIV is attractive because it gives value for money in terms of features."
"Implementing Remote mirroring and local Snaps is very easy."
 

Cons

"The design is a little old-fashioned and could be updated."
"IBM FlashSystem 5300 needs improvement in its deduplication and compression features."
"The security features can be improved such that the encryption does not affect performance in any way."
"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."
"The stability of the solution isn't great; we have had a lot of issues with discs over the years."
"Our customers have raised concerns about the limitations of the FlashSystem 5200 and 7300, which only offer a 32-gigabyte connection."
"IBM FlashSystems is lagging in optimizing storage technologies, which can be improved."
"The deduplication and compression ratio is not very good. It's not reaching a very high ratio."
"Management accessibility. Both the GUI and the CLI require installation of a Java-based thick client, which is ridiculous, plus a drain on resources."
"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 guess we'd like to see the XIV keep pace with how storage is going in terms of speed and latency."
"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."
"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 would rather have a web GUI served directly from the unit, and a CLI accessible directly through SSH."
"IBM XIV's scalability is adequate for our requirements, but because it's modular, you can't scale to larger requirements."
 

Pricing and Cost Advice

"This is an expensive product and if the price were reduced it would be better."
"The price of IBM FlashSystem is a little high because you pay a premium because the solution is from IBM. We had paid for the SLA prior to using the solution."
"You purchase it as a bundle and the price is comparable."
"Our customers would like IMB FlashSystem to be less expensive."
"The price of IBM FlashSystem is reasonable."
"They've been much more aggressive in the last five, six years than they were before that."
"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."
"I would rate the pricing of this solution a four out of five."
"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."
"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."
