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 valuable features of IBM FlashSystem include flash copy mapping, which is a procedure to collect instant point-in-time data for testing real data."
"Data deduplication is one of the most valuable features of this solution."
"One of the valuable features is the performance, it is one of the best in the market."
"User friendly management interface."
"The price-performance ratio is most valuable."
"We are a 100% satisfied with the stability of the solution."
"The speed, performance, and stability are the best features of IBM FlashSystem."
"This solution is very stable."
"Installation is amazingly easy."
"Very easy to produce reporting data (Snaps). Very easy and fast for provisioning devices and Remote mirroring."
"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."
"IBM XIV's most valuable features are NVME, especially when it comes to de-duplication, compression, and responsiveness."
"The performance and robustness of the systems are very good."
 

Cons

"The interface of this solution could be improved."
"The GUI for monitoring performance metrics could provide better visibility. For example, it doesn't let me segregate the IOPS per volume."
"I think the only thing the developers can look at, is that it is limited to 25 gigabytes currently. In the next release they might want to increase that."
"The product needs to improve their scalability."
"The deduplication and compression ratio is not very good. It's not reaching a very high ratio."
"I would like to have a larger disk. Right now, you can get 57 terabytes in a shelf. Once they get the larger disk and you get larger capacities, it'll be even better."
"The pricing needs to be more competitive."
"Product support is restricted to IBM only. It must be decentralized to IBM partners as well."
"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."
"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."
"The change form synchronous mirroring to asynchronous (and vice versa) without reconfiguration from scratch would be helpful."
"Until the drive is replaced, the pool_resizing is locked."
"I would rather have a web GUI served directly from the unit, and a CLI accessible directly through SSH."
 

Pricing and Cost Advice

"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."
"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."
"I price of IBM FlashSystem is reasonable and competitive."
"The cost of the IBM FlashSystem is lower than the HPE solution."
"Pricing can be considered as per market competition."
"There are no licensing fees, it is a one-time purchase of the IBM FlashSystem."
"The price of IBM FlashSystem is reasonable."
"The price is a little bit high so is rated a six out of ten."
"Licensing is straightforward."
"No-license-required policy, unlike others where you need a license for everything. Just pay once and forget about licenses."
"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."
"We have a five-year total cost of ownership where we pay an initial amount and then annually for maintenance."
