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 most valuable features are flexibility and performance."
"Installing FlashSystem is very easy. It takes less than half an hour, and I can handle it all myself."
"IBM FlashSystem has been stable in our operations."
"AHV is Acropolis Hypervisor – A relatively new Hypervisor, robust and stable as VMware vSphere, has built-in advanced analytics and powerful operations, Self Service Portal and components for DevOps included, managed by a single pane of glass (Prism) via HTML5 and it is free of charge – That is why Nutanix is so advanced and revolutionary."
"The maintenance service and support from IBM is very good."
"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."
"It's one of the first, fully software-defined solutions on the market available."
"The cost was low when we purchased it."
"The performance and robustness of the systems are very good."
"For us, the XIV is pretty much set-it-and-forget-it storage."
"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."
"Implementing Remote mirroring and local Snaps is very easy."
"XIV setup is very straightforward and easy to configure."
"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."
"IBM XIV is attractive because it gives value for money in terms of features."
 

Cons

"Additional licenses might be added for the fundamental licenses, such as those for copying and flash copies."
"The stability of the solution isn't great; we have had a lot of issues with discs over the years."
"This product lacks some of the options we wanted. For example, expansion was difficult and it required a lot of patching to be done."
"The cluster should be improved because non-disruptive failover was supported only on a few operating systems."
"This is an expensive product and if the price were reduced it would be better."
"The GUI needs some improvement."
"The interface could improve in IBM FlashSystem."
"Their technical support needs improvement in terms of reachability for the clients and response times."
"I guess we'd like to see the XIV keep pace with how storage is going in terms of speed and latency."
"IBM XIV's scalability is adequate for our requirements, but because it's modular, you can't scale to larger requirements."
"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."
"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."
"The change form synchronous mirroring to asynchronous (and vice versa) without reconfiguration from scratch would be helpful."
"IBM XIV's scalability is adequate for our requirements, but because it's modular, you can't scale to larger requirements."
"Until the drive is replaced, the pool_resizing is locked."
 

Pricing and Cost Advice

"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 cost is pretty high in terms of licensing. We pay at least $100,000 USD in licensing fees for the storage."
"They've been much more aggressive in the last five, six years than they were before that."
"The price of IBM FlashSystem is reasonable."
"The tool is cost-efficient."
"I price of IBM FlashSystem is reasonable and competitive."
"Its price is very good."
"The solution has good pricing, but it is not cheaper."
"We have a five-year total cost of ownership where we pay an initial amount and then annually for maintenance."
"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."

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...
