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

"This storage has incredible performance, the I/O is awesome."
"The solution is very flexible."
"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."
"The most valuable feature in demand is virtualization and its support storage of virtualization features."
"The performance of the All-Flash System is very good. There is more enhanced performance and data production in the solution, which I appreciate."
"The valuable features are high availability, compression, and a failover mechanism. It's a very highly available storage solution."
"The setup was straightforward, it is pretty easy and I can do it with my eyes closed, if I wanted to."
"The all-flash storage has tier replication capabilities."
"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."
"IBM XIV is attractive because it gives value for money in terms of features."
"As it spreads, a chuck of 1MB across the board means using all available spindles on the backend."
"Installation is amazingly easy."
"Implementing Remote mirroring and local Snaps is very easy."
"XIV setup is very straightforward and easy to configure."
"For us, the XIV is pretty much set-it-and-forget-it storage."
"Hands down, this is the easiest storage platform on the market to manage."
 

Cons

"It is slightly more expensive, however, it all depends on your supplier."
"The storage capacity of this solution could be improved."
"It has room for improvement in the area of stability."
"The solution's pricing is a bit high so there is room for improvement."
"Cloud file sharing is an area that needs improvement."
"There's always room for improvement. Adding deduplication would allow us to get more bang for our buck, basically."
"We faced power supply failure, multiple SAS drives failure, and at the end both controllers were dead."
"The storage size vs the storage price needs to improve."
"I would rather have a web GUI served directly from the unit, and a CLI accessible directly through SSH."
"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."
"Management accessibility. Both the GUI and the CLI require installation of a Java-based thick client, which is ridiculous, plus a drain on resources."
"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."
"Until the drive is replaced, the pool_resizing is locked."
"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."
 

Pricing and Cost Advice

"Our customers would like IMB FlashSystem to be less expensive."
"The solution has good pricing, but it is not cheaper."
"The total storage capacity vs price is still quite high for the IBM Flash Array."
"There are no licensing fees, it is a one-time purchase of the IBM FlashSystem."
"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 pricing may be a bit higher than other brands. If you compare the IBM FlashSystems in midrange with Dell EMC in midrange, IBM costs a bit more, but I prefer IBM because it has more specs that I can benefit from."
"For a yearly license, it is about $100,000. There are no additional costs. The entire system is included."
"We have no issues with the price as it is very competitive."
"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."
"No-license-required policy, unlike others where you need a license for everything. Just pay once and forget about licenses."
"Licensing is straightforward."
