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

"Initial SAN configuration was smooth."
"The speed, performance, and stability are the best features of IBM FlashSystem."
"It is simple to make an update."
"The Flash core models offer amazing performance."
"User friendly management interface."
"As a result of the accelerated read and write operations from disks, productivity across the enterprise has increased in daily work."
"The initial setup is straightforward and can be done in an hour and a half by one person."
"After we migrated them under the IBM Flash Array, the overall IOPS rate has increased by 30% and its latency is lower."
"Very easy to produce reporting data (Snaps). Very easy and fast for provisioning devices and Remote mirroring."
"IBM XIV is attractive because it gives value for money in terms of features."
"Hands down, this is the easiest storage platform on the market 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."
"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."
"Installation is amazingly easy."
"Implementing Remote mirroring and local Snaps is very easy."
 

Cons

"The stability is not very good."
"Support is horrible. It takes weeks to get simple answers."
"The interface of this solution could be improved."
"The array level RAID does not seem available."
"The initial setup is complex."
"Recently, we deployed SS9100. At the core level that is deployed on that storage, it is not stable."
"IBM FlashSystems is lagging in optimizing storage technologies, which can be improved."
"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."
"Until the drive is replaced, the pool_resizing is locked."
"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."
"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."
"The change form synchronous mirroring to asynchronous (and vice versa) without reconfiguration from scratch would be helpful."
"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."
 

Pricing and Cost Advice

"For a yearly license, it is about $100,000. There are no additional costs. The entire system is included."
"The pricing is reasonable."
"This is an expensive product and if the price were reduced it would be better."
"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 price is a little bit high so is rated a six out of ten."
"The price of IBM FlashSystem is reasonable."
"The pricing is competitive in our country."
"If five is a good price and one is a high price, I would rate the price a two or three out of five."
"No-license-required policy, unlike others where you need a license for everything. Just pay once and forget about licenses."
"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."
"Licensing is straightforward."
