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 stability is awesome, based off a mature product line that has been around since 1999, combining two well-known and well-proven technologies into a very solid solution."
"High availability and enhanced security; Proven dependability; Data compression with hardware acceleration; Advanced copy services features are all in this product."
"One of the most valuable features is that it's very easy to use and configure. It used to be more difficult, but now it's almost flawless."
"One of the valuable features is the performance, it is one of the best in the market."
"Customer service is very good."
"The most valuable features are deduplication and compression, which together, enable you to have more space."
"The most valuable features are deduplication and compression, which together, enable you to have more space."
"The installation and service was very good."
"Very easy to produce reporting data (Snaps). Very easy and fast for provisioning devices and Remote mirroring."
"The product is exceptionally reliable and very easy to manage."
"For us, the XIV is pretty much set-it-and-forget-it storage."
"As it spreads, a chuck of 1MB across the board means using all available spindles on the backend."
"The performance and robustness of the systems are very good."
"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."
"Hands down, this is the easiest storage platform on the market 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."
"We think that IBM has to continue to invest in additional data reduction capabilities which are on their roadmap."
"It doesn't scale out that well."
"The GUI needs some improvement. An additional function that could be helpful is reducing the time it takes to delete volumes, especially if they are compressed or deduplicated."
"Flash Manager needs to be included."
"The interface of this solution could be improved."
"Our customers have raised concerns about the limitations of the FlashSystem 5200 and 7300, which only offer a 32-gigabyte connection."
"Include an option to upload the support package to the IBM ECuRep when opening an IBM PMR."
"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."
"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 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."
"Management accessibility. Both the GUI and the CLI require installation of a Java-based thick client, which is ridiculous, plus a drain on resources."
"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."
 

Pricing and Cost Advice

"They've been much more aggressive in the last five, six years than they were before that."
"Pricing can be considered as per market competition."
"If five is a good price and one is a high price, I would rate the price a two or three out of five."
"I price of IBM FlashSystem is reasonable and competitive."
"For a yearly license, it is about $100,000. There are no additional costs. The entire system is included."
"The price of IBM FlashSystem is reasonable."
"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."
"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."
"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."
"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."

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...
