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

"IBM Storwize makes management of the IT environment much easier, with high availability and enhanced security, proven dependability, data compression with hardware acceleration, and advanced copy services features all in this product."
"IBM FlashSystem is a powerful effective storage solution. Additionally, it is user-friendly, anyone can use it."
"The most valuable feature of the solution is compression."
"The price-performance ratio is most valuable; it is simple to use, and both the performance and interface are good."
"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."
"I rate the technical support from IBM as a ten."
"The most valuable features are flexibility and performance."
"When it comes to the interface of the solution we did not encounter any challenges. Additionally, the solution has good documentation."
"Installation is amazingly easy."
"IBM XIV is attractive because it gives value for money in terms of features."
"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."
"Hands down, this is the easiest storage platform on the market to manage."
"As it spreads, a chuck of 1MB across the board means using all available spindles on the backend."
"Implementing Remote mirroring and local Snaps is very easy."
"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."
 

Cons

"Recently, we deployed SS9100. At the core level that is deployed on that storage, it is not stable."
"Replication features need improvement. Currently, they are there in the product, but I'm not sure as to how it works exactly."
"The technical support in my region is satisfactory but it could improve. Support is very important for customers and downtime is very critical for us. We would like onsite or complete technical support which can help us to minimize our downtime or if problems occur."
"I have used support and it needs improvement."
"When you provision a datastore auto-format takes a long time .. to disable is you have to redo the whole process. this is a bit difficult if you want to make adjustments on the datastore"
"This solution could be improved by offering greater amounts of storage."
"The interface of this solution could be improved."
"The storage capacity of this solution could be improved."
"I guess we'd like to see the XIV keep pace with how storage is going in terms of speed and latency."
"Until the drive is replaced, the pool_resizing is locked."
"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."
"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."
"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."
"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

"The pricing is competitive in our country."
"We have no issues with the price as it is very competitive."
"Regarding licensing make sure you add at least three years software maintenance from IBM at the beginning, because you will not be able to download firmware updates or any fixes/patches without this."
"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."
"Pricing can be considered as per market competition."
"The solution has good pricing, but it is not cheaper."
"I'd rate the basic licensing and the Virtualize software a ten out of ten, and the extra Spectrum and other an eight out of ten."
"I find the pricing of the solution to be very reasonable."
"Licensing is straightforward."
"We have a five-year total cost of ownership where we pay an initial amount and then annually for maintenance."
"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."

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...
