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

"IBM products at the enterprise level are stable solutions, with a score of nine out of ten for stability."
"For space saving features, it definitely saves us in a virtual environment in terms of space and money."
"The most valuable feature is reliability."
"This solution is really user friendly, offers good performance, and is highly reliable."
"IBM FlashSystem provides a very good value."
"It is a good storage solution, but there many other options out there with more resources."
"IBM FlashSystem is a powerful effective storage solution, and it is user-friendly, anyone can use it."
"One of the valuable features is the performance, it is one of the best in the market."
"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."
"Implementing Remote mirroring and local Snaps is very easy."
"Hands down, this is the easiest storage platform on the market to manage."
"IBM XIV is attractive because it gives value for money in terms of features."
"The performance and robustness of the systems are very good."
"The product is exceptionally reliable and very easy to manage."
"IBM XIV's most valuable features are NVME, especially when it comes to de-duplication, compression, and responsiveness."
 

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 solution should improve its pricing and the mechanism in the reduction pool."
"Sometimes the performance is effective but it gets resolved in the process."
"Recently, we deployed SS9100. At the core level that is deployed on that storage, it is not stable."
"We faced power supply failure, multiple SAS drives failure, and at the end both controllers were dead."
"The installation is not easy. You need to have extensive knowledge to handle it."
"The customer's expectations are what they get on the cloud, they're expecting even in the on-premises deployments, going forward."
"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."
"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."
"IBM XIV's scalability is adequate for our requirements, but because it's modular, you can't scale to larger requirements."
"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 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."
"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

"For a yearly license, it is about $100,000. There are no additional costs. The entire system is included."
"Pricing can be considered as per market competition."
"Our customers would like IMB FlashSystem to be less expensive."
"There are no licensing fees, it is a one-time purchase of the IBM FlashSystem."
"This solution is expensive compared to other solutions."
"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 price is a little bit high so is rated a six out of ten."
"This is an expensive product and if the price were reduced it would be better."
"Licensing is straightforward."
"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."
"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."
