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 very stable solution and its default rate is low."
"This solution is very stable."
"The IBM System is top-notch and offers all the features we need to keep going for another 5 years."
"The most valuable features are, of course, the virtualization of the storage, the performance, and the compression."
"The performance is very good and we use this product to enhance our core system."
"The GUI is very easy and performance is also good."
"The most valuable features are flexibility and performance."
"This solution is convenient, user-friendly, convenient and reliable."
"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."
"For us, the XIV is pretty much set-it-and-forget-it storage."
"Installation is amazingly easy."
"As it spreads, a chuck of 1MB across the board means using all available spindles on the backend."
"Hands down, this is the easiest storage platform on the market to manage."
"XIV setup is very straightforward and easy to configure."
"Implementing Remote mirroring and local Snaps is very easy."
 

Cons

"It is slightly more expensive, however, it all depends on your supplier."
"The solution is not easy to use and could improve."
"The pricing needs to be more competitive."
"Support response times are bad."
"Technical support is complicated. The technical support can be improved, it should be more automated."
"Our model does not support compression or deduplication."
"The data reduction pool feature sucks and is not recommended for use with heavy workloads."
"Additional licenses might be added for the fundamental licenses, such as those for copying and flash copies."
"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."
"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."
"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 would rather have a web GUI served directly from the unit, and a CLI accessible directly through SSH."
"Management accessibility. Both the GUI and the CLI require installation of a Java-based thick client, which is ridiculous, plus a drain on resources."
 

Pricing and Cost Advice

"Regarding licensing make sure you add at least three years software maintenance from IBM at the beginning, because you will not be able to download firmware updates or any fixes/patches without this."
"They've been much more aggressive in the last five, six years than they were before that."
"Among IBM, Dell EMC, and Pure Storage, IBM is the cheapest. The price is also based on our location, the size of our entity, and our regular annual purchases from them. We are a very big IBM customer, so we normally get very high discounts. We are not a big customer of Pure Storage. We don't buy that much from Pure Storage per year. Everything is included in the price. There is no extra license for different functions."
"The solution requires a license and could be less expensive."
"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."
"The pricing has been very competitive for the last few years. IBM got to the point where they changed the pricing model and we feel very comfortable with the pricing. It's very competitive. Over the last two years, IBM has been coming up with all kinds of interesting promos, especially for the SMB systems. That makes it very competitive price-wise and in terms of performance..."
"There are no licensing fees, it is a one-time purchase of the IBM FlashSystem."
"The price is a little bit high so is rated a six out of ten."
"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."
