Offers cost-effective storage for small companies with budget constraints
IBM FlashSystem 5300 is offered at a very low cost in Israel, which is advantageous for small companies. However, other features like deduplication and compression do not perform effectively. The price sensitivity makes it a viable option for clients with budgetary constraints, as it allows us to secure deals based on the cost rather than advanced performance.
Ajith Kandaramage - PeerSpot reviewer
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 ability to create LUNs and modify them are the most valuable features of this solution."
"The speed, performance, and stability are the best features of IBM FlashSystem."
"Ability to manage third-party arrays and virtualise them: One screen to control multiple arrays. Simplified administration."
"The valuable features for us are the extra add-ons, such as the FIM provisioning, the compression, the disaster recovery capabilities, and the storage pooling functions."
"The most crucial feature of IBM FlashSystem is compression."
"The solution is very easy to configure and use."
"The Flash core models offer amazing performance."
"The most valuable feature is reliability."
"As it spreads, a chuck of 1MB across the board means using all available spindles on the backend."
"Very easy to produce reporting data (Snaps). Very easy and fast for provisioning devices and Remote mirroring."
"Installation is amazingly easy."
"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."
 

Cons

"The interface could improve in IBM FlashSystem."
"The pricing needs to be more competitive."
"Customization features must be improved."
"The GUI needs some improvement."
"The security features can be improved such that the encryption does not affect performance in any way."
"The marketing could be improved."
"In IBM FlashSystem, data reduction is an area with shortcomings where improvements can be made in the future."
"It could be easier to implement."
"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 would rather have a web GUI served directly from the unit, and a CLI accessible directly through SSH."
"Until the drive is replaced, the pool_resizing is locked."
"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."
"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."
 

Pricing and Cost Advice

"The pricing is reasonable."
"I'd rate the basic licensing and the Virtualize software a ten out of ten, and the extra Spectrum and other an eight out of ten."
"The price is a little bit high so is rated a six out of ten."
"The price of IBM FlashSystem is reasonable."
"I would rate the pricing of this solution a four out of five."
"For a yearly license, it is about $100,000. There are no additional costs. The entire system is included."
"The pricing is competitive in our country."
"You purchase it as a bundle and the price is comparable."
"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."
"We have a five-year total cost of ownership where we pay an initial amount and then annually for maintenance."
