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

"Biggest return is the easy migration and upgrade path as well as the scalability options, with IBM adding compression and deduplication in its portfolio, as well as garbage collection and space reclamation."

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

"IBM FlashSystem is flexible, quick, and has a solid design."

"It is simple to make an update."

"With IBM FlashSystem the report takes two hours or less than a two-hour on a rotation, we can get our reports very quickly and this is something very valuable to our management."

"The stability's been rock solid."

"The price-performance ratio is most valuable."

"If you are looking for a great flash solution that can be virtualized or utilized as a building block for a scalable flash solution, or if you're looking for flash for a very specific workload, then you may want to consider a FlashSystem 900."

More IBM FlashSystem pros

"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."

"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."

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

"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."

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

"Implementing Remote mirroring and local Snaps is very easy."

More IBM XIV pros

Cons

"The pricing needs to be more competitive."

"The solution is not able to replicate data in one-to-many scenario."

"It should increase sociability with respect to number of disk shelves and capacity."

"The product could be cheaper."

"Deduplication and DRC synchronization. Deduplication is small, limited. We need better deduplication and disaster recovery."

"Technical support is horrible. IBM doesn't have much expertise with the product."

"The technical support in my region is satisfactory but it could improve. Support is very important for customers and downtime is very critical for us. We would like onsite or complete technical support which can help us to minimize our downtime or if problems occur."

"The GUI needs some improvement."

More IBM FlashSystem cons

"I guess we'd like to see the XIV keep pace with how storage is going in terms of speed and latency."

"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."

"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."

"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."

More IBM XIV cons

Pricing and Cost Advice

"For a yearly license, it is about $100,000. There are no additional costs. The entire system is included."

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

"The solution has good pricing, but it is not cheaper."

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

"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."

"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."

"Its price is very good."

"The pricing is competitive in our country."

More IBM FlashSystem pricing and cost advice

"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."
