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

"Ability to manage third-party arrays and virtualise them: One screen to control multiple arrays. Simplified administration."

"The most valuable feature is reliability."

"The most valuable features are deduplication and compression."

"IBM FlashSystem is a stable solution."

"The feature I find most valuable, is the deduplication, because the nature of the data that we are using in our current environment, has a lot of replicated data."

"The performance of the solution is noteworthy."

"One of the most valuable features is that it's very easy to use and configure. It used to be more difficult, but now it's almost flawless."

"I would recommend it to other users."

More IBM FlashSystem pros

"Very easy to produce reporting data (Snaps). Very easy and fast for provisioning devices and Remote mirroring."

"The performance and robustness of the systems are very good."

"As it spreads, a chuck of 1MB across the board means using all available spindles on the backend."

"IBM XIV's most valuable features are NVME, especially when it comes to de-duplication, compression, and responsiveness."

"Hands down, this is the easiest storage platform on the market to manage."

"Installation is amazingly easy."

Cons

"The security features can be improved such that the encryption does not affect performance in any way."

"There is room for improvement in the troubleshooting part, specifically related to IBM Spectrum for Insight."

"In IBM FlashSystem, data reduction is an area with shortcomings where improvements can be made in the future."

"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."

"The interface of this solution could be improved."

"The product needs to improve their scalability."

"The array level RAID does not seem available."

More IBM FlashSystem cons

"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."

"IBM XIV's scalability is adequate for our requirements, but because it's modular, you can't scale to larger requirements."

"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."

"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."

"I would rather have a web GUI served directly from the unit, and a CLI accessible directly through SSH."

Pricing and Cost Advice

"If five is a good price and one is a high price, I would rate the price a two or three out of five."

"I price of IBM FlashSystem is reasonable and competitive."

"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."

"There are no licensing fees, it is a one-time purchase of the IBM FlashSystem."

"The pricing may be a bit higher than other brands. If you compare the IBM FlashSystems in midrange with Dell EMC in midrange, IBM costs a bit more, but I prefer IBM because it has more specs that I can benefit from."

"The pricing is competitive in our country."

"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."

"This is an expensive product and if the price were reduced it would be better."

More IBM FlashSystem pricing and cost advice

"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."

"Licensing is straightforward."
