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 features are deduplication and compression."
"The stability is quite good, there are no bugs or glitches, it doesn't crash or freeze, and it's a very reliable product."
"Technical support is very proactive and we receive alerts when they are visiting the data center or asking for permission to change a part."
"It's very easy to manage."
"If you have the funds and you require speed, this product is the answer."
"IBM FlashSystem has been stable in our operations."
"The speed, performance, and stability are the best features of IBM FlashSystem."
"The initial setup is very easy and can be done by one person."
"IBM XIV's most valuable features are NVME, especially when it comes to de-duplication, compression, and responsiveness."
"XIV setup is very straightforward and easy to configure."
"Installation is amazingly easy."
"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."
"Hands down, this is the easiest storage platform on the market to manage."
"The product is exceptionally reliable and very easy to manage."
"The performance and robustness of the systems are very good."
 

Cons

"The data reduction pool feature sucks and is not recommended for use with heavy workloads."
"The deduplication and compression ratio is not very good. It's not reaching a very high ratio."
"Our customers have raised concerns about the limitations of the FlashSystem 5200 and 7300, which only offer a 32-gigabyte connection."
"The basic setup can be challenging when it comes to certain IP addresses and the configuration of the IP. You have to go in to different menus to makes changes and ensure it is stable."
"The data reduction pool feature sucks and is not recommended for use with heavy workloads."
"The solution is not able to replicate data in one-to-many scenario."
"There could be some extra features added."
"It has room for improvement in the area of stability."
"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 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."
"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."
"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."
"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."
 

Pricing and Cost Advice

"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 cost of the IBM FlashSystem is lower than the HPE solution."
"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."
"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."
"I find the pricing of the solution to be very reasonable."
"I would rate the pricing of this solution a four out of five."
"We have a five-year total cost of ownership where we pay an initial amount and then annually for maintenance."
"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."
"Licensing is straightforward."
"No-license-required policy, unlike others where you need a license for everything. Just pay once and forget about licenses."

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...
