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 most valuable feature of the solution is SCM (Storage Class Memory), which has the lowest latency value in the storage industry."
"It's very easy to manage."
"The performance of IBM FlashSystem is very good. The new technology and high throughput have given us more confidence in the solution. The management of the system has improved and we can control the monitoring system alerts and multiple FlashSystems with the Enterprise Cloud Edition, which is free. The migration of recently stored data to a new flash is much easier. You can move your data because you can utilize it externally."
"With IBM FlashSystem the report takes two hours or less than a two-hour on a rotation, we can get our reports very quickly and this is something very valuable to our management."
"All this storage infrastructure can be done underneath one IBM Storwize product and this is how it has impacted our organization."
"The ease-of-use and scalability are the most valuable features."
"IBM FlashSystem is fast and reliable."
"Stability-wise, this solution is fine."
"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."
"XIV setup is very straightforward and easy to configure."
"As it spreads, a chuck of 1MB across the board means using all available spindles on the backend."
"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."
"Installation is amazingly easy."
"For us, the XIV is pretty much set-it-and-forget-it storage."
"Very easy to produce reporting data (Snaps). Very easy and fast for provisioning devices and Remote mirroring."
 

Cons

"I would like to see an improvement in the handling of large amounts of rights."
"Deduplication feature is not mature and it is significantly increasing the latency."
"The design is a little old-fashioned and could be updated."
"Replication features need improvement. Currently, they are there in the product, but I'm not sure as to how it works exactly."
"In the next release having the next level of high-speed performance would be great."
"The support could improve by allowing you to speak to someone when you call rather than them calling you back. However, once we do have contact with one of their technicians they are excellent."
"This solution could be improved by offering greater amounts of storage."
"This product lacks some of the options we wanted. For example, expansion was difficult and it required a lot of patching to be done."
"I would rather have a web GUI served directly from the unit, and a CLI accessible directly through SSH."
"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."
"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."
"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."
"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."
 

Pricing and Cost Advice

"I price of IBM FlashSystem is reasonable and competitive."
"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."
"If five is a good price and one is a high price, I would rate the price a two or three out of five."
"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 pricing is reasonable."
"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 cost of the IBM FlashSystem is lower than the HPE solution."
"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."
"Licensing is straightforward."
"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...
