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.

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

"Over the years, it has become increasingly user-friendly."
"The most valuable features were the performance of the array, i.e., very low latency and high IOPS. Plus, the management interface is very easy to use."
"Parsing is the most valuable feature inside IBM Spectrum Virtualize software, which allows us to virtualize any third-party storage for IBM or non-IBM systems."
"IBM FlashSystem has been stable in our operations."
"IBM FlashSystem is a powerful effective storage solution. Additionally, it is user-friendly, anyone can use it."
"The feature I find most valuable, is the deduplication, because the nature of the data that we are using in our current environment, has a lot of replicated data."
"Stability-wise, this solution is fine."
"Stability-wise, this solution is fine."
"Installation is amazingly easy."
"As it spreads, a chuck of 1MB across the board means using all available spindles on the backend."
"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."
"Hands down, this is the easiest storage platform on the market to manage."
"XIV setup is very straightforward and easy to configure."
"Very easy to produce reporting data (Snaps). Very easy and fast for provisioning devices and Remote mirroring."
"The product is exceptionally reliable and very easy to manage."
"Implementing Remote mirroring and local Snaps is very easy."
 

Cons

"I would like to have a larger disk. Right now, you can get 57 terabytes in a shelf."
"The solution is not easy to use and could improve."
"The price is very costly."
"The several major crashes resulted in the entire weekends being lost in rebuilding the array and then for restoring the data."
"IBM could do more marketing and improve brand awareness. I had never heard of this product until a colleague told me about it. FlashSystem could add a few features, but it would probably increase the price. For example, Pure Storage offers instant snapshotting and partitioning. That would be nice to have, but I think the cost would go up."
"Include an option to upload the support package to the IBM ECuRep when opening an IBM PMR."
"This solution needs a management console where we are alerted to issues and can report them, or escalate them through email or another method."
"Technical support is horrible. IBM doesn't have much expertise with the product."
"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."
"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."
"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 would rather have a web GUI served directly from the unit, and a CLI accessible directly through SSH."
"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."
"The change form synchronous mirroring to asynchronous (and vice versa) without reconfiguration from scratch would be helpful."
 

Pricing and Cost Advice

"Among IBM, Dell EMC, and Pure Storage, IBM is the cheapest. The price is also based on our location, the size of our entity, and our regular annual purchases from them. We are a very big IBM customer, so we normally get very high discounts. We are not a big customer of Pure Storage. We don't buy that much from Pure Storage per year. Everything is included in the price. There is no extra license for different functions."
"Overall the price of the solution is expensive and this includes the license."
"Pricing can be considered as per market competition."
"The pricing has been very competitive for the last few years. IBM got to the point where they changed the pricing model and we feel very comfortable with the pricing. It's very competitive. Over the last two years, IBM has been coming up with all kinds of interesting promos, especially for the SMB systems. That makes it very competitive price-wise and in terms of performance..."
"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."
"The solution has good pricing, but it is not cheaper."
"The price is a little bit high so is rated a six out of ten."
"You purchase it as a bundle and the price is comparable."
"Licensing is straightforward."
"We have a five-year total cost of ownership where we pay an initial amount and then annually for maintenance."
"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."

Questions from the Community

The pricing is high; storage solutions are always expensive. I do not know if the price needs to be reviewed, but it is worth considering.
What needs improvement with IBM FlashSystem?
As far as I know, IBM FlashSystem has already improved, but I do not see room for improvement. It is simple to use and manage via SVC, simple to configure, and even for the zoning, I do not see imp...
