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

"It is simple to make an update."
"IBM FlashSystem is the best solution for storage virtualization."
"Flash disk with Easy Tier option"
"Stability-wise, this solution is fine."
"The initial customer technical support was efficient and effective."
"The solution allows for easy migrations from previous products or vendors via its embedded storage virtualization function."
"This solution is really user friendly. It also offers good performance and is highly reliable."
"IBM FlashSystem is a stable solution."
"As it spreads, a chuck of 1MB across the board means using all available spindles on the backend."
"IBM XIV's most valuable features are NVME, especially when it comes to de-duplication, compression, and responsiveness."
"Hands down, this is the easiest storage platform on the market to manage."
"The performance and robustness of the systems are very good."
"Installation is amazingly easy."
"Very easy to produce reporting data (Snaps). Very easy and fast for provisioning devices and Remote mirroring."
 

Cons

"Additional licenses might be added for the fundamental licenses, such as those for copying and flash copies."
"The storage capacity of this solution could be improved."
"With regards to the IBM V7000 storage system, where we have multiple tiers of storage, a heat map would show I/O distribution across the tiers of storage."
"The pricing needs to be more competitive."
"The solution has a low number of NVME host attachments at 16 per IO group over the fiber channel."
"The array level RAID does not seem available."
"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 deduplication and compression ratio is not very good. It's not reaching a very high ratio."
"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 would rather have a web GUI served directly from the unit, and a CLI accessible directly through SSH."
"The change form synchronous mirroring to asynchronous (and vice versa) without reconfiguration from scratch would be helpful."
"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."
 

Pricing and Cost Advice

"There are no licensing fees, it is a one-time purchase of the IBM FlashSystem."
"It pays to go back and get the best price you can from your supplier. The first offer is not always at the best discount."
"The pricing is competitive in our country."
"They've been much more aggressive in the last five, six years than they were before that."
"The pricing has been very competitive for the last few years. IBM got to the point where they changed the pricing model and we feel very comfortable with the pricing. It's very competitive. Over the last two years, IBM has been coming up with all kinds of interesting promos, especially for the SMB systems. That makes it very competitive price-wise and in terms of performance..."
"The solution requires a license and could be less expensive."
"I find the pricing of the solution to be very reasonable."
"My customers got the IBM FlashSystem bundle offer. It was a one-time purchase for three years of service. The price would depend on the storage size and could reach between $25,000 to $55,000."
"No-license-required policy, unlike others where you need a license for everything. Just pay once and forget about licenses."
"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."

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...
