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

"The GUI is very easy and performance is also good."

"The stability is awesome, based off a mature product line that has been around since 1999, combining two well-known and well-proven technologies into a very solid solution."

"The initial customer technical support was efficient and effective."

"The documentation is excellent so far, the solution is very fast and offers very good flexibility with a pretty decent price point, and the product is user-friendly with an easy setup process."

"Virtualization of external storage, while adding cache and speed to the external storage."

"The most valuable features are deduplication and compression, which together, enable you to have more space."

"The initial setup was easy, understandable, and straightforward."

"The Flash core models offer amazing performance."

More IBM FlashSystem pros

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

"Installation is amazingly 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."

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

"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."

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

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

More IBM XIV pros

Cons

"When you provision a datastore auto-format takes a long time"

"The solution should improve its pricing and the mechanism in the reduction pool."

"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."

"There is a need for a little bit more of a drill down in the GUI part."

"The pricing needs to be more competitive."

"I have used support and it needs improvement."

"The marketing could be improved."

"Cloud file sharing is an area that needs improvement."

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."

"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."

"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."

"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."

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

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

More IBM XIV cons

Pricing and Cost Advice

"The solution requires a license and could be less expensive."

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

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

"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..."

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

"The price depends of the technology that our customers need. The price can come at a lower cost but this may increase as storage is added."

"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 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."

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."

"Licensing is straightforward."

"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."
