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 a stable solution."
"The Flash core models offer amazing performance."
"The solution is scalable and has varying degrees of scalability."
"It is very, very stable, and we have never had issues."
"Stability-wise, this solution is fine."
"Customer service is very good."
"IBM FlashSystem is a very stable solution and its default rate is low."
"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."
"XIV setup is very straightforward and easy to configure."
"The product is exceptionally reliable and very easy to manage."
"Hands down, this is the easiest storage platform on the market to manage."
"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."
"Installation is amazingly easy."
"IBM XIV is attractive because it gives value for money in terms of features."
"As it spreads, a chuck of 1MB across the board means using all available spindles on the backend."
 

Cons

"My advice to anybody who is considering this system is not to do it. I do not recommend it; it is a big no."
"I have used support and it needs improvement."
"The solution should improve its pricing and the mechanism in the reduction pool."
"We had issues when attempting to do a flash, we hope to resolve it soon."
"Support is horrible. It takes weeks to get simple answers."
"When you provision a datastore auto-format takes a long time .. to disable is you have to redo the whole process. this is a bit difficult if you want to make adjustments on the datastore"
"There is a need for a little bit more of a drill down in the GUI part."
"It is slightly more expensive, however, it all depends on your supplier."
"Until the drive is replaced, the pool_resizing is locked."
"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."
"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."
"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."
"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."
 

Pricing and Cost Advice

"The cost of the IBM FlashSystem is lower than the HPE solution."
"The pricing may be a bit higher than other brands. If you compare the IBM FlashSystems in midrange with Dell EMC in midrange, IBM costs a bit more, but I prefer IBM because it has more specs that I can benefit from."
"This is an expensive product and if the price were reduced it would be better."
"It pays to go back and get the best price you can from your supplier. The first offer is not always at the best discount."
"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."
"For a yearly license, it is about $100,000. There are no additional costs. The entire system is included."
"The tool is cost-efficient."
"This solution is expensive compared to other solutions."
"No-license-required policy, unlike others where you need a license for everything. Just pay once and forget about licenses."
"We have a five-year total cost of ownership where we pay an initial amount and then annually for maintenance."
"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."

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...
