Infrastructure Technical Specialist II at Clicks Group
Offers high performance and dependable support for fast storage needs
The most valuable feature of IBM FlashSystem is its robust back code. When integrated properly into the environment and configured according to the guidelines, it provides a very solid infrastructure that does the job on demand. Additionally, IBM FlashSystem offers competitive pricing and reliable performance. The hardware is dependable, ensuring that it functions effectively when the setup is done correctly.

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 setup was straightforward, it is pretty easy and I can do it with my eyes closed, if I wanted to."
"Stability-wise, this solution is fine."
"IBM FlashSystem is a flexible solution with plenty of features."
"Our automatic banking systems have become twice as quick with flash storage."
"The most valuable feature in demand is virtualization and its support storage of virtualization features."
"Most of the features for the reduction in data compression are useful, and it is also very easy to use and administer, with good performance."
"At the FlashSystem level, customers are especially fond of multi-tier and distributed rate systems, particularly the dynamic rate six arrays."
"It is very, very stable, and we have never had issues."
"IBM XIV is attractive because it gives value for money in terms of features."
"XIV setup is very straightforward and easy to configure."
"Hands down, this is the easiest storage platform on the market to manage."
"As it spreads, a chuck of 1MB across the board means using all available spindles on the backend."
"The product is exceptionally reliable and very easy to manage."
"Implementing Remote mirroring and local Snaps is very easy."
"Very easy to produce reporting data (Snaps). Very easy and fast for provisioning devices and Remote mirroring."
"IBM XIV's most valuable features are NVME, especially when it comes to de-duplication, compression, and responsiveness."
 

Cons

"We had issues when attempting to do a flash, we hope to resolve it soon."
"Replication features need improvement. Currently, they are there in the product, but I'm not sure as to how it works exactly."
"The stability is not very good."
"Our model does not support compression or deduplication."
"This product lacks some of the options we wanted. For example, expansion was difficult and it required a lot of patching to be done."
"The data reduction pool feature sucks and is not recommended for use with heavy workloads."
"This solution could be improved by offering greater amounts of storage."
"It could be easier to implement."
"Management accessibility. Both the GUI and the CLI require installation of a Java-based thick client, which is ridiculous, plus a drain on resources."
"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."
"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 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 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."
"The change form synchronous mirroring to asynchronous (and vice versa) without reconfiguration from scratch would be helpful."
"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."
 

Pricing and Cost Advice

"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."
"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."
"You purchase it as a bundle and the price is comparable."
"I price of IBM FlashSystem is reasonable and competitive."
"Overall the price of the solution is expensive and this includes the license."
"The integration is already included in the license cost of IBM FlashSystem. The integration is very easy. You get the IBM storage core with all software, firmware, and upgrades. EMC provides the features in the box, but they are not free for customers. There is a licensing cost for features. We have yearly licensing, but IBM has also provided a new option where you pay as you go. They provide a big box, and I pay, for example, for 10 terabytes. If I exceed 10 terabytes, IBM will charge for the new storage after 10 terabytes. It is a good opportunity in the market for using the storage as a cloud and paying as you go."
"The solution has good pricing, but it is not cheaper."
"Pricing can be considered as per market competition."
"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."
"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."
"Licensing is straightforward."
