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

"The benefit of the product is the ease-of-management; it has significantly reduced the IT operation costs to our organization."
"The speed of the unit is its best feature. It performs very well."
"The FlashSystem 900 consistently delivers performance below 1ms for read/write. This performance is essential for an effective SVC stretch-cluster configuration across two datacenters, and presenting active-active storage to the customer."
"When it comes to the interface of the solution we did not encounter any challenges. Additionally, the solution has good documentation."
"IBM FlashSystem is a stable solution."
"One of the most valuable features is that it's very easy to use and configure. It used to be more difficult, but now it's almost flawless."
"Customer service is very good."
"The maintenance service and support from IBM is very good."
"IBM XIV's most valuable features are NVME, especially when it comes to de-duplication, compression, and responsiveness."
"As it spreads, a chuck of 1MB across the board means using all available spindles on the backend."
"XIV setup is very straightforward and easy to configure."
"The product is exceptionally reliable and very easy to manage."
"Installation is amazingly easy."
"Very easy to produce reporting data (Snaps). Very easy and fast for provisioning devices and Remote mirroring."
"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."
"Implementing Remote mirroring and local Snaps is very easy."
 

Cons

"This storage is factory configured so it's very difficult and expensive to add more flash modules (disk capacity)."
"We sometimes had a problem with some bugs in FlashSystems. One time, one FlashSystem was burnt up. There was some smoke and the data was damaged."
"In the next release having the next level of high-speed performance would be great."
"Technical support is horrible. IBM doesn't have much expertise with the product."
"Our model does not support compression or deduplication."
"There could be some extra features added."
"Flash Manager needs to be included."
"GUI interface should be enhanced more as there is some issues in copy services."
"Management accessibility. Both the GUI and the CLI require installation of a Java-based thick client, which is ridiculous, plus a drain on resources."
"I would rather have a web GUI served directly from the unit, and a CLI accessible directly through SSH."
"Until the drive is replaced, the pool_resizing is locked."
"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 has been an issue a lot of times, especially when the contract says IBM will not replace disks until three drives fail."
"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."
"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

"They've been much more aggressive in the last five, six years than they were before that."
"The price of IBM FlashSystem is reasonable."
"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."
"IBM V7000 has a new license and price structure which provides intuitive licensing based on the functions customers wish to enable and use the most."
"The solution requires a license and could be less expensive."
"The tool is cost-efficient."
"The cost of the IBM FlashSystem is lower than the HPE solution."
"There are no licensing fees, it is a one-time purchase of the IBM FlashSystem."
"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."
"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...
