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

"If you are targeting functionality, we get the most functionality from IBM FlashSystem, and then from Pure Storage, and then from Dell EMC boxes."
"It's a mature product. It's like a BMW that evolves consistently."
"IBM FlashSystem provides a very good value."
"I would recommend it to other users."
"It is very, very stable, and we have never had issues."
"I rate the technical support from IBM as a ten."
"The most crucial feature of IBM FlashSystem is compression."
"The initial setup is very easy and can be done by one person."
"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."
"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."
"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."
"The product is exceptionally reliable and very easy to manage."
 

Cons

"The solution is quite expensive. That's one of the downsides to using it."
"Cloud file sharing is an area that needs improvement."
"The cluster should be improved because non-disruptive failover was supported only on a few operating systems."
"We had issues when attempting to do a flash, we hope to resolve it soon."
"They can improve its initial configuration. The initial configuration is currently very difficult. There are multiple choices or alternative ways to configure based on the use case and what you are targeting out of the device, that is, more capacity or more performance. These multiple alternatives cause a lot of confusion. They should increase the processing part of the nodes. Currently, you can cluster up to eight nodes. From my experience and the workload that I am facing in my environment currently, I would like to see either a bigger or stronger node or a larger number of nodes that can be clustered together. We formally communicated to them that we need to see either this or that, and they are working on something."
"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 have a larger disk. Right now, you can get 57 terabytes in a shelf. Once they get the larger disk and you get larger capacities, it'll be even better."
"The storage size vs the storage price needs to improve."
"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."
"I guess we'd like to see the XIV keep pace with how storage is going in terms of speed and latency."
"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."
"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."
"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."
 

Pricing and Cost Advice

"The price of IBM FlashSystem is reasonable."
"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 cost of the IBM FlashSystem is lower than the HPE solution."
"There are no licensing fees, it is a one-time purchase of the IBM FlashSystem."
"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 would rate the pricing of this solution a four out of five."
"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."
"I price of IBM FlashSystem is reasonable and competitive."
"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."
