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

"The most valuable feature of the solution is replication...Stability-wise, I rate the solution a nine out of ten."
"IBM FlashSystem has improved the way the organizations of my customers function."
"The performance of the All-Flash System is very good. There is more enhanced performance and data production in the solution, which I appreciate."
"After we migrated them under the IBM Flash Array, the overall IOPS rate has increased by 30% and its latency is lower."
"High availability and enhanced security; Proven dependability; Data compression with hardware acceleration; Advanced copy services features are all in this product."
"AHV is Acropolis Hypervisor – A relatively new Hypervisor, robust and stable as VMware vSphere, has built-in advanced analytics and powerful operations, Self Service Portal and components for DevOps included, managed by a single pane of glass (Prism) via HTML5 and it is free of charge – That is why Nutanix is so advanced and revolutionary."
"The initial setup is very easy and can be done by one person."
"The initial setup was really straightforward. It was not complex. Deployment took one month, due to the data migration duration."
"IBM XIV's most valuable features are NVME, especially when it comes to de-duplication, compression, and responsiveness."
"Implementing Remote mirroring and local Snaps is very easy."
"Installation is amazingly easy."
"For us, the XIV is pretty much set-it-and-forget-it storage."
"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."
"XIV setup is very straightforward and easy to configure."
"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."
 

Cons

"There is a need for more help with the commands because, from version to version, they change; so what I used to use back in the different version, I can't use now."
"The solution has a low number of NVME host attachments at 16 per IO group over the fiber channel."
"The array level RAID does not seem available."
"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."
"The solution should improve its pricing and the mechanism in the reduction pool."
"The pricing needs to be more competitive."
"We faced power supply failure, multiple SAS drives failure, and at the end both controllers were dead."
"The customer's expectations are what they get on the cloud, they're expecting even in the on-premises deployments, going forward."
"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."
"Until the drive is replaced, the pool_resizing is locked."
"IBM XIV's scalability is adequate for our requirements, but because it's modular, you can't scale to larger requirements."
"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 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."
 

Pricing and Cost Advice

"The price is a little bit high so is rated a six out of ten."
"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."
"The total storage capacity vs price is still quite high for the IBM Flash Array."
"Its price is very good."
"Our customers would like IMB FlashSystem to be less expensive."
"Pricing can be considered as per market competition."
"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 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..."
"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."
"No-license-required policy, unlike others where you need a license for everything. Just pay once and forget about licenses."
"We have a five-year total cost of ownership where we pay an initial amount and then annually for maintenance."

Questions from the Community

What is your experience regarding pricing and costs for IBM FlashSystem?
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...
