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 speed, performance, and stability are the best features of IBM FlashSystem."
"Installing FlashSystem is very easy. It takes less than half an hour, and I can handle it all myself."
"IBM FlashSystem is the best solution for storage virtualization."
"The most valuable features are, of course, the virtualization of the storage, the performance, and the compression."
"User friendly management interface."
"The valuable features for us are the extra add-ons, such as the FIM provisioning, the compression, the disaster recovery capabilities, and the storage pooling functions."
"The power systems are very reliable if you are running 24/7 operations. For ongoing mission-critical applications, it's the best solution."
"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."
"Hands down, this is the easiest storage platform on the market to manage."
"Installation is amazingly easy."
"IBM XIV's most valuable features are NVME, especially when it comes to de-duplication, compression, and responsiveness."
"The performance and robustness of the systems are very good."
"Very easy to produce reporting data (Snaps). Very easy and fast for provisioning devices and Remote mirroring."
"As it spreads, a chuck of 1MB across the board means using all available spindles on the backend."
 

Cons

"Our model does not support compression or deduplication."
"The basic setup can be challenging when it comes to certain IP addresses and the configuration of the IP. You have to go in to different menus to makes changes and ensure it is stable."
"The installation is not easy. You need to have extensive knowledge to handle it."
"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."
"The deduplication technology in IBM FlashSystem needs significant improvement."
"Our customers have raised concerns about the limitations of the FlashSystem 5200 and 7300, which only offer a 32-gigabyte connection."
"They can include Amazon file system S3 protocol in the upcoming releases. It is a cloud file system. IBM FlashSystem doesn't have this feature in the box for high-end or mid-range. We have got requests for this from customers because we need to use S3 for EDI application storage. At the beginning of every year, IBM releases firmware. When I find any bugs in the firmware during the year, I am unable to find any information from IBM regarding the bug. I need to open a ticket, and the IBM engineering team makes a patch only for me. This patch is not public. By creating a customized patch for a client, they don't really solve the issue for everyone. If multiple users have the same bug, IBM should upload the patch on the official website so that we can download it. IBM FlashSystem has a monitoring tool in the box, but it is not advanced. I need a more advanced tool for more advanced equations and monitoring. All top three storage vendors, that is, EMC, IBM, and Pure Storage, don't have a powerful monitoring tool. To monitor our box to show the statistics for I/Os and latency, I need to pay for extra software. The built-in monitoring storage is not mature enough to handle all requests and generate all reports that I need. They can include the functionality to stretch a cluster natively without using any additional boxes. In addition, there are some features that EMC has integrated with the box. These features are not available in IBM FlashSystem."
"I would like to see bigger modules."
"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."
"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 would rather have a web GUI served directly from the unit, and a CLI accessible directly through SSH."
"Until the drive is replaced, the pool_resizing is locked."
 

Pricing and Cost Advice

"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..."
"Our customers would like IMB FlashSystem to be less expensive."
"My customers got the IBM FlashSystem bundle offer. It was a one-time purchase for three years of service. The price would depend on the storage size and could reach between $25,000 to $55,000."
"You purchase it as a bundle and the price is comparable."
"For a yearly license, it is about $100,000. There are no additional costs. The entire system is included."
"The price of IBM FlashSystem is reasonable."
"I price of IBM FlashSystem is reasonable and competitive."
"Its price is very good."
"No-license-required policy, unlike others where you need a license for everything. Just pay once and forget about licenses."
"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."
