Infrastructure Technical Specialist II at Clicks Group
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.
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 installation is nice and easy."
"The good thing is that it is very easy to use and anybody can allocate Launch to the systems."
"For space saving features, it definitely saves us in a virtual environment in terms of space and money."
"The installation and service was very good."
"IBM FlashSystem has been stable in our operations."
"The price-performance ratio is most valuable; it is simple to use, and both the performance and interface are good."
"After we migrated them under the IBM Flash Array, the overall IOPS rate has increased by 30% and its latency is lower."
"The storage system is one of the best in the world."
"IBM XIV is attractive because it gives value for money in terms of features."
"Hands down, this is the easiest storage platform on the market to manage."
"Very easy to produce reporting data (Snaps). Very easy and fast for provisioning devices and Remote mirroring."
"Installation is amazingly easy."
"For us, the XIV is pretty much set-it-and-forget-it storage."
"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 performance and robustness of the systems are very good."
 

Cons

"If you want to expand, you cannot expand the disc enclosure. You have to buy a total individual node. Sometimes, this is difficult because we are just looking for capacity and not a node."
"This storage is factory configured so it's very difficult and expensive to add more flash modules (disk capacity)."
"I have looked at a few pages of a report I download and I saw a graph there regarding software-defined vendors. IBM is not in a good position on this graph. I know that they are working very hard on this, to make it much better and to get to a level where it's not only hardware but also software to provide a complete solution."
"The only issue my team faced was transferring the data from the old system to IBM FlashSystem, which is an area for improvement in the solution."
"One area for improvement is in the GUI, where host clusters are not properly dealt with. With Hypervisor host clusters, all hosts must see the same volumes in the same order. Using the concept of a “host-group” has been around (even with IBM) for many years, so why not with the V7000?"
"The product could be cheaper."
"The storage size vs the storage price needs to improve."
"The marketing could be improved."
"Management accessibility. Both the GUI and the CLI require installation of a Java-based thick client, which is ridiculous, plus a drain on resources."
"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. This has been an issue a lot of times, especially when the contract says IBM will not replace disks until three drives fail."
"I would rather have a web GUI served directly from the unit, and a CLI accessible directly through SSH."
"I guess we'd like to see the XIV keep pace with how storage is going in terms of speed and latency."
"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."
"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

"For a yearly license, it is about $100,000. There are no additional costs. The entire system is included."
"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."
"The total storage capacity vs price is still quite high for the IBM Flash Array."
"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 pricing is competitive in our country."
"The price is a little bit high so is rated a six out of ten."
"Our customers would like IMB FlashSystem to be less expensive."
"No-license-required policy, unlike others where you need a license for everything. Just pay once and forget about licenses."
"Licensing is straightforward."
"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."
