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 FlashSystem is fast and reliable."

"The most valuable feature of the solution is compression."

"The most valuable features in IBM FlashSystem are IOPS, performance, duplication, and compression."

"This solution is very scalable."

"For ongoing mission-critical applications, it's the best solution."

"Customer service is very good."

"User friendly interface Robust hardware Good support"

"The solution allows for easy migrations from previous products or vendors via its embedded storage virtualization function."

More IBM FlashSystem pros

"The product is exceptionally reliable and very easy to manage."

"For us, the XIV is pretty much set-it-and-forget-it storage."

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

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

"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."

"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."

More IBM XIV pros

Cons

"The GUI for monitoring performance metrics could provide better visibility. For example, it doesn't let me segregate the IOPS per volume."

"A big area for improvement is that the data reduction pool feature is not recommended for use in a production environment because it has stability and performance issues."

"Their technical support needs improvement in terms of reachability for the clients and response times."

"This product lacks some of the options we wanted. For example, expansion was difficult and it required a lot of patching to be done."

"It doesn't scale out that well."

"The support could improve by allowing you to speak to someone when you call rather than them calling you back. However, once we do have contact with one of their technicians they are excellent."

"The customer's expectations are what they get on the cloud, they're expecting even in the on-premises deployments, going forward."

"This solution could be improved by offering greater amounts of storage."

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."

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

"Management accessibility. Both the GUI and the CLI require installation of a Java-based thick client, which is ridiculous, plus a drain on resources."

"The change form synchronous mirroring to asynchronous (and vice versa) without reconfiguration from scratch would be helpful."

"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 has been an issue a lot of times, especially when the contract says IBM will not replace disks until three drives fail."

"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."

More IBM XIV cons

Pricing and Cost Advice

"The price of IBM FlashSystem is reasonable."

"The cost is pretty high in terms of licensing. We pay at least $100,000 USD in licensing fees for the storage."

"It pays to go back and get the best price you can from your supplier. The first offer is not always at the best discount."

"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."

"Among IBM, Dell EMC, and Pure Storage, IBM is the cheapest. The price is also based on our location, the size of our entity, and our regular annual purchases from them. We are a very big IBM customer, so we normally get very high discounts. We are not a big customer of Pure Storage. We don't buy that much from Pure Storage per year. Everything is included in the price. There is no extra license for different functions."

"We have no issues with the price as it is very competitive."

"I would rate the pricing of this solution a four out of five."

"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..."

More IBM FlashSystem pricing and cost advice

"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."

"Licensing is straightforward."
