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 solution is currently hosting our core banking system and we haven't faced any stability issues, so it is very stable."

"The most valuable feature in demand is virtualization and its support storage of virtualization features."

"It's a mature product. It's like a BMW that evolves consistently."

"The solution is very flexible."

"IBM FlashSystem has an easy to use GUI, similar to the IBM Storewize family, which make it one of the best flash storage systems in the market."

"Storage virtualization simplifies space management, thin provisioning saves space, and copy services simplify environment replication."

"The hardware is the best feature of the product."

More IBM FlashSystem pros

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

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

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

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

"IBM XIV is attractive because it gives value for money in terms of features."

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

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

More IBM XIV pros

Cons

"This storage is factory configured so it's very difficult and expensive to add more flash modules (disk capacity)."

"There is a need for more help with the commands because, from version to version, they change; so what I used to use back in the different version, I can't use now."

"The GUI needs some improvement. An additional function that could be helpful is reducing the time it takes to delete volumes, especially if they are compressed or deduplicated."

"The solution's infrastructure technology level could be PCI Express 5 instead of PCI Express 4 for the next version."

"Support response times are bad."

"The generic functionality of IBM FlashSystem, IBM always dismisses using file share or sharing protocols inside their storage hardware, and they only focus on the block-level storage."

"The solution is not easy to use and could improve."

"If you want to expand, you cannot expand the disc enclosure. You have to buy a total individual node. Sometimes, this is difficult because we are just looking for capacity and not a node."

More IBM FlashSystem cons

"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."

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

"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."

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

"Until the drive is replaced, the pool_resizing is locked."

"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."

More IBM XIV cons

Pricing and Cost Advice

"I find the pricing of the solution to be very reasonable."

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

"The price of IBM FlashSystem is a little high because you pay a premium because the solution is from IBM. We had paid for the SLA prior to using the solution."

"The cost of the IBM FlashSystem is lower than the HPE solution."

"Our customers would like IMB FlashSystem to be less expensive."

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

"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 price is a little bit high so is rated a six out of ten."

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."

"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."

"Licensing is straightforward."
