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

"Stability-wise, this solution is fine."
"If you have the funds and you require speed, this product is the answer."
"The price-performance ratio is most valuable; it is simple to use, and both the performance and interface are good."
"Installing FlashSystem is very easy. It takes less than half an hour, and I can handle it all myself."
"User friendly management interface."
"The performance is very good and we use this product to enhance our core system."
"The most valuable features of IBM FlashSystem are performance and security."
"The initial setup is very easy and can be done by one person."
"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."
"Very easy to produce reporting data (Snaps). Very easy and fast for provisioning devices and Remote mirroring."
"Implementing Remote mirroring and local Snaps is very easy."
"The product is exceptionally reliable and very easy to manage."
"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."
"For us, the XIV is pretty much set-it-and-forget-it storage."
 

Cons

"We use some open-source tools for monitoring, such as Grafana and it should be bundled along with IBM FlashSystem."
"Our model does not support compression or deduplication."
"Our customers have raised concerns about the limitations of the FlashSystem 5200 and 7300, which only offer a 32-gigabyte connection."
"This is an expensive product and if the price were reduced it would be better."
"The cluster should be improved because non-disruptive failover was supported only on a few operating systems."
"The GUI needs some improvement."
"Technical support is complicated. The technical support can be improved, it should be more automated."
"I know they have a flashcopy manager, but it is extra software, an additional license, and some customers don't like to add addition costs to their infrastructure. If IBM could create, or include snapshot management within the GUI, that would really be helpful."
"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."
"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."
"The change form synchronous mirroring to asynchronous (and vice versa) without reconfiguration from scratch would be helpful."
"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."
"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."
 

Pricing and Cost Advice

"The solution requires a license and could be less expensive."
"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..."
"Pricing can be considered as per market competition."
"The pricing is competitive in our country."
"The price of IBM FlashSystem is a little high because you pay a premium because the solution is from IBM. We had paid for the SLA prior to using the solution."
"The solution has good pricing, but it is not cheaper."
"Overall the price of the solution is expensive and this includes the license."
"I would rate the pricing of this solution a four out of five."
"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."
"Licensing is straightforward."
