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 initial setup is very easy and can be done by one person."
"When it comes to the interface of the solution we did not encounter any challenges. Additionally, the solution has good documentation."
"The most crucial feature of IBM FlashSystem is compression."
"The most valuable features are flexibility and performance."
"Our automatic banking systems have become twice as quick with flash storage."
"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."
"Installing FlashSystem is very easy; it takes less than half an hour, and I can handle it all myself."
"Stability-wise, this solution is fine."
"IBM XIV's most valuable features are NVME, especially when it comes to de-duplication, compression, and responsiveness."
"The product is exceptionally reliable and very easy to manage."
"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."
"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."
"Hands down, this is the easiest storage platform on the market to manage."
"Very easy to produce reporting data (Snaps). Very easy and fast for provisioning devices and Remote mirroring."
 

Cons

"The solution is not easy to implement. It takes a lot of time to study the product and it's a little complicated in general."
"The marketing could be improved."
"Technical Support: Not so good in my country because they only have a few people with great knowledge about FlashSystem."
"GUI interface should be enhanced more as there is some issues in copy services GUI interfaces should be enhanced as this will not let the customer doing wrong configurations"
"The price is very costly, which could be improved."
"It is slightly more expensive, however, it all depends on your supplier."
"IBM FlashSystems is lagging in optimizing storage technologies, which can be improved."
"Their technical support needs improvement in terms of reachability for the clients and response times."
"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."
"I guess we'd like to see the XIV keep pace with how storage is going in terms of speed and latency."
"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."
"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."

"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."
 

Pricing and Cost Advice

"We have no issues with the price as it is very competitive."
"The integration is already included in the license cost of IBM FlashSystem. The integration is very easy. You get the IBM storage core with all software, firmware, and upgrades. EMC provides the features in the box, but they are not free for customers. There is a licensing cost for features. We have yearly licensing, but IBM has also provided a new option where you pay as you go. They provide a big box, and I pay, for example, for 10 terabytes. If I exceed 10 terabytes, IBM will charge for the new storage after 10 terabytes. It is a good opportunity in the market for using the storage as a cloud and paying as you go."
"The cost is pretty high in terms of licensing. We pay at least $100,000 USD in licensing fees for the storage."
"Its price is very good."
"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."
"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."
"The pricing is competitive in our country."
"This solution is expensive compared to other solutions."
"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."
"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."

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...
