Infrastructure Technical Specialist II at Clicks Group
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

"Most of the features for the reduction in data compression are useful. It is also very easy to use and administer. Its performance is also good."
"The stability's been rock solid."
"IBM FlashSystem is flexible, quick, and has a solid design."
"It's very easy to manage."
"This solution is really user friendly. It also offers good performance and is highly reliable."
"IBM FlashSystem 5300 is offered at a very low cost in Israel, which is advantageous for small companies."
"All this storage infrastructure can be done underneath one IBM Storwize product and this is how it has impacted our organization."
"The GUI is very easy and performance is also good."
"Implementing Remote mirroring and local Snaps is very easy."
"XIV setup is very straightforward and easy to configure."
"Hands down, this is the easiest storage platform on the market to manage."
"IBM XIV is attractive because it gives value for money in terms of features."
"IBM XIV's most valuable features are NVME, especially when it comes to de-duplication, compression, and responsiveness."
"Installation is amazingly easy."
"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 solution is not able to replicate data in one-to-many scenario."
"Our customers have raised concerns about the limitations of the FlashSystem 5200 and 7300, which only offer a 32-gigabyte connection."
"This solution needs a management console where we are alerted to issues and can report them, or escalate them through email or another method."
"Customization features must be improved."
"We use some open-source tools for monitoring, such as Grafana and it should be bundled along with IBM FlashSystem."
"The solution has a low number of NVME host attachments at 16 per IO group over the fiber channel; this is magnitudes lower than competing products."
"The data reduction pool feature sucks and is not recommended for use with heavy workloads."
"I know they have a flashcopy manager, but it is extra software, an additional license, and some customers don't like to add addition costs to their infrastructure."
"Until the drive is replaced, the pool_resizing is locked."
"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."
"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."
"IBM XIV's scalability is adequate for our requirements, but because it's modular, you can't scale to larger requirements."
"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."
"I guess we'd like to see the XIV keep pace with how storage is going in terms of speed and latency."
 

Pricing and Cost Advice

"Its price is very good."
"This solution is expensive compared to other solutions."
"For a yearly license, it is about $100,000. There are no additional costs. The entire system is included."
"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."
"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."
"I'd rate the basic licensing and the Virtualize software a ten out of ten, and the extra Spectrum and other an eight out of ten."
"We have no issues with the price as it is very competitive."
"The tool is cost-efficient."
"No-license-required policy, unlike others where you need a license for everything. Just pay once and forget about licenses."
"Licensing is straightforward."
"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."

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...
