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 product is so easy to use."
"IBM FlashSystem provides a very good value."
"The speed and the ease of installation are the most valuable features."
"Initial SAN configuration was smooth."
"The most valuable feature is that is supports a high IOPS rate."
"The most valuable features are, of course, the virtualization of the storage, the performance, and the compression."
"Flash disk with Easy Tier option"
"The most valuable features in IBM FlashSystem are IOPS, performance, duplication, and compression."
"IBM XIV's most valuable features are NVME, especially when it comes to de-duplication, compression, and responsiveness."
"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."
"The product is exceptionally reliable and very easy to manage."
"IBM XIV is attractive because it gives value for money in terms of features."
"Implementing Remote mirroring and local Snaps is very easy."
"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."
"XIV setup is very straightforward and easy to configure."
 

Cons

"The stability is not very good."
"Enterprise data storage needs improvement. They should create a feature for data and file storage."
"The customer's expectations are what they get on the cloud, they're expecting even in the on-premises deployments, going forward."
"The price is very costly."
"Support is horrible. It takes weeks to get simple answers."
"This solution could be improved by offering greater amounts of storage."
"GUI interface should be enhanced more as there is some issues in copy services."
"In the next release having the next level of high-speed performance would be great."
"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."
"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."
"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."
"IBM XIV's scalability is adequate for our requirements, but because it's modular, you can't scale to larger requirements."
"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."
 

Pricing and Cost Advice

"This is an expensive product and if the price were reduced it would be better."
"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."
"Pricing can be considered as per market competition."
"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."
"IBM V7000 has a new license and price structure which provides intuitive licensing based on the functions customers wish to enable and use the most."
"The tool is cost-efficient."
"The solution requires a license and could be less expensive."
"The solution has good pricing, but it is not cheaper."
"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."
