Offers cost-effective storage for small companies with budget constraints
IBM FlashSystem 5300 is offered at a very low cost in Israel, which is advantageous for small companies. However, other features like deduplication and compression do not perform effectively. The price sensitivity makes it a viable option for clients with budgetary constraints, as it allows us to secure deals based on the cost rather than advanced performance.
Ajith Kandaramage - PeerSpot reviewer
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 technical support for this solution is good. They used to help us when the motherboard of Power Systems broke. Their response times are really fast."
"Ability to manage third-party arrays and virtualise them: One screen to control multiple arrays. Simplified administration."
"The valuable feature is autoscalling."
"The speed and the ease of installation are the most valuable features."
"The most valuable feature of the solution is replication...Stability-wise, I rate the solution a nine out of ten."
"IBM FlashSystem has been stable in our operations."
"The valuable features for us are the extra add-ons, such as the FIM provisioning, the compression, the disaster recovery capabilities, and the storage pooling functions."
"This solution is really user friendly. It also offers good performance and is highly reliable."
"As it spreads, a chuck of 1MB across the board means using all available spindles on the backend."
"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."
"Installation is amazingly easy."
"Very easy to produce reporting data (Snaps). Very easy and fast for provisioning devices and Remote mirroring."
"Hands down, this is the easiest storage platform on the market to manage."
 

Cons

"The ease of installation should be improved. We had issues with the configuration model."
"The pricing could be improved, but I think it's getting better and better with each version. IBM needs to implement NAS storage again, as this is a big flaw. Dell EMC is very good at this and if you compared them based on NAS storage, Dell EMC would win right away. IBM's solution for NAS storage is very complicated. We don't have a storage box that provides file sharing from itself, we have to put software on it and go through a whole complicated process. It should be simplified."
"The deduplication technology in IBM FlashSystem needs significant improvement."
"The price is very costly."
"The solution has a low number of NVME host attachments at 16 per IO group over the fiber channel."
"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."
"Events/log analysis tools."
"I would like to have a larger disk. Right now, you can get 57 terabytes in a shelf. Once they get the larger disk and you get larger capacities, it'll be even better."
"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 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."
"IBM XIV's scalability is adequate for our requirements, but because it's modular, you can't scale to larger requirements."
"The change form synchronous mirroring to asynchronous (and vice versa) without reconfiguration from scratch would be helpful."
"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."
 

Pricing and Cost Advice

"Overall the price of the solution is expensive and this includes the license."
"I find the pricing of the solution to be very reasonable."
"This is an expensive product and if the price were reduced it would be better."
"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 pricing is competitive in our country."
"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."
"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."
"Licensing is straightforward."
"No-license-required policy, unlike others where you need a license for everything. Just pay once and forget about licenses."
