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 of all the products are the high performance and micro latency."
"The valuable feature is autoscalling."
"IBM FlashSystem is a flexible solution with plenty of features."
"FlashSystem offers proven technology in a compact package."
"The most valuable features were the performance of the array, i.e., very low latency and high IOPS. Plus, the management interface is very easy to use."
"The initial setup was really straightforward. It was not complex. Deployment took one month, due to the data migration duration."
"At the FlashSystem level, customers are especially fond of multi-tier and distributed rate systems, particularly the dynamic rate six arrays."
"The good thing is that it is very easy to use and anybody can allocate Launch to the systems."
"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."
"Implementing Remote mirroring and local Snaps is very easy."
"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."
"The product is exceptionally reliable and very easy to manage."
"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."
"Installation is amazingly easy."
 

Cons

"This is an expensive solution compared to other similar solutions."
"We faced power supply failure, multiple SAS drives failure, and at the end both controllers were dead."
"The solution has a low number of NVME host attachments at 16 per IO group over the fiber channel; this is magnitudes lower than competing products."
"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 initial setup is complex."
"It should increase sociability with respect to number of disk shelves and capacity."
"This product lacks some of the options we wanted. For example, expansion was difficult and it required a lot of patching to be done."
"They can improve its initial configuration. The initial configuration is currently very difficult."
"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."
"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."
"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."
"The change form synchronous mirroring to asynchronous (and vice versa) without reconfiguration from scratch would be helpful."
"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."
"I guess we'd like to see the XIV keep pace with how storage is going in terms of speed and latency."
"I would rather have a web GUI served directly from the unit, and a CLI accessible directly through SSH."
 

Pricing and Cost Advice

"The pricing is competitive in our country."
"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 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."
"The tool is cost-efficient."
"The price of IBM FlashSystem is reasonable."
"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 cost is pretty high in terms of licensing. We pay at least $100,000 USD in licensing fees for the storage."
"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."
"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."
