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

"Licensing has already everything you need like replication, but you need to consider the license cost for the SAN switch."
"For ongoing mission-critical applications, it's the best solution."
"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 maintenance service and support from IBM is very good."
"The installation and service was very good."
"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."
"Biggest return is the easy migration and upgrade path as well as the scalability options, with IBM adding compression and deduplication in its portfolio, as well as garbage collection and space reclamation."
"If you are targeting functionality, we get the most functionality from IBM FlashSystem, and then from Pure Storage, and then from Dell EMC boxes."
"The product is exceptionally reliable and very easy to manage."
"Implementing Remote mirroring and local Snaps is very easy."
"Installation is amazingly easy."
"XIV setup is very straightforward and easy to configure."
"For us, the XIV is pretty much set-it-and-forget-it storage."
"IBM XIV's most valuable features are NVME, especially when it comes to de-duplication, compression, and responsiveness."
"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."
"The performance and robustness of the systems are very good."
 

Cons

"The product could be cheaper."
"The technical support in my region is satisfactory but it could improve."
"Sometimes the performance is effective but it gets resolved in the process."
"Technical support is complicated. The technical support can be improved, it should be more automated."
"I would like to see an improvement in the handling of large amounts of rights."
"The initial setup is complex."
"We had issues when attempting to do a flash, we hope to resolve it soon."
"There could be some extra features added."
"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."
"I guess we'd like to see the XIV keep pace with how storage is going in terms of speed and latency."
"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."
"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."
"Management accessibility. Both the GUI and the CLI require installation of a Java-based thick client, which is ridiculous, plus a drain on resources."
 

Pricing and Cost Advice

"My customers got the IBM FlashSystem bundle offer. It was a one-time purchase for three years of service. The price would depend on the storage size and could reach between $25,000 to $55,000."
"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."
"For a yearly license, it is about $100,000. There are no additional costs. The entire system is included."
"Pricing can be considered as per market competition."
"This is an expensive product and if the price were reduced it would be better."
"The pricing is reasonable."
"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."
"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."
"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."

Questions from the Community

What is your experience regarding pricing and costs for IBM FlashSystem?
The pricing is high; storage solutions are always expensive. I do not know if the price needs to be reviewed, but it is worth considering.
What needs improvement with IBM FlashSystem?
As far as I know, IBM FlashSystem has already improved, but I do not see room for improvement. It is simple to use and manage via SVC, simple to configure, and even for the zoning, I do not see imp...
