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

"Go ahead and implement it. IBM storage provides you everything that you’ll need for a block-level architecture, as they have many different products which provides you with a variety of options to meet your needs."

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

"The IBM System is top-notch and offers all the features we need to keep going for another 5 years."

"IBM FlashSystem provides a very good value."

"The ease-of-use and scalability are the most valuable features."

"The ability to create LUNs and modify them are the most valuable features of this solution."

"It's a really reliable, powerful platform; it's a mature product, like a BMW that evolves consistently, with storage virtualization, easy volume migration, stretch capabilities, Site Recovery Adapter, backup integration using flash copies, and everything you need to build a robust disaster recovery solution around it."

"The FlashSystem 900 consistently delivers performance below 1ms for read/write. This performance is essential for an effective SVC stretch-cluster configuration across two datacenters, and presenting active-active storage to the customer."

More IBM FlashSystem pros

"Installation is amazingly easy."

"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."

"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."

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

"XIV setup is very straightforward and easy to configure."

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

More IBM XIV pros

Cons

"The basic setup can be challenging when it comes to certain IP addresses and the configuration of the IP. You have to go in to different menus to makes changes and ensure it is stable."

"The problem is that if the buffer is not configured correctly this increases the latency because of this delay and the retransmit."

"GUI interface should be enhanced more as there is some issues in copy services."

"It is slightly more expensive, however, it all depends on your supplier."

"When you provision a datastore auto-format takes a long time .. to disable is you have to redo the whole process. this is a bit difficult if you want to make adjustments on the datastore"

"The only issue my team faced was transferring the data from the old system to IBM FlashSystem, which is an area for improvement in the solution."

"We had issues when attempting to do a flash, we hope to resolve it soon."

"The GUI needs some improvement."

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."

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

"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 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

"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."

"Overall the price of the solution is expensive and this includes the license."

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

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

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

"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."

"The price of IBM FlashSystem is reasonable."

"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."

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."

"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."

"Licensing is straightforward."
