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…

Has supported long-term data protection and backup while requiring better part availability and pricing options
For monitoring purposes, we normally use flash access storage exclusively. We utilize a hybrid system because we need performance, combining NL-SAS for the volume and SAS flash to use as a fast cache system that provides more IOPS. We normally implement RAID 10, which we prefer over RAID 6's n plus 2 combinations. We utilize it for data redundancy, even with write intensity on. Regarding the unified storage architecture for NetApp FAS Series, we normally opt for exclusivity unless budget constraints exist. Our IOPS are very high, reaching somewhere about 50k to 150k or 1.150k. The high performance ensures minimal latency. An advantage we've seen with NetApp FAS Series is that snapshots provide very rapid backup and fast recovery. We basically use snapshots for data protection as first-level protection, with deduplication between the two storages serving as second-level protection.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The performance and robustness of the systems are very good."
"XIV setup is very straightforward and easy to configure."
"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'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."
"Installation is amazingly easy."
"IBM XIV is attractive because it gives value for money in terms of features."
"It is a scalable solution."
"It’s top-notch support, very responsive and highly knowledgeable, very attentive to us as we have a monthly meeting with our TAM."
"If you need reliability, definitely go for NetApp."
"I would definitely recommend NetApp FAS Series to other users because it's stable and really handy for IT personnel who manage it."
"It is good to have a unified storage where you can have block and file level protocols."
"It’s a Swiss army knife of capabilities, with flexible platform and software features like thin provisioning, compression, and dedupe that help with capacity utilization and still deliver a lot of return even when following best-practices applications."
"They are very satisfied with NetApp and continue to use NetApp and upgrade to new solutions."
"The performance allows me to provide backend storage for large number of VMs and databases at a competitive price point."
 

Cons

"Until the drive is replaced, the pool_resizing is locked."
"I guess we'd like to see the XIV keep pace with how storage is going in terms of speed and latency."
"IBM XIV's scalability is adequate for our requirements, but because it's modular, you can't scale to larger requirements."
"IBM XIV's scalability is adequate for our requirements, but because it's modular, you can't scale to larger requirements."
"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."
"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."
"Interfacing with the cloud environment could be better. I want to be able to move some cloud volume and integrate it seamlessly with my home on-premise storage. Sometimes I have issues with port permissions. NetApp probably needs to improve more on the integration side from on-premise to the cloud."
"I have not given the FAS a perfect rating because the All Flash Array is probably going to beat it down, in terms of performance."
"The process for going to cluster mode is expensive."
"There are some technical limitations, but it would be great to have in-line deduplication and in-line compression for the FAS series as well."
"The product should improve its user experience."
"I have a very small feature request: more automation of the expanding aggregates and discs."
"The NetApp FAS Series is not as high-performing and is not as fast. Its speed needs improvement, but this could only be done if it's an all-flash solution."
"We no longer have OEM support in South Africa which is not helpful, it can be difficult. They should add an office back to the country because it was better."
 

Pricing and Cost Advice

"No-license-required policy, unlike others where you need a license for everything. Just pay once and forget about licenses."
"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."
"We have a five-year total cost of ownership where we pay an initial amount and then annually for maintenance."
"Most storage vendors also have software, or licensing bundles, which may offer the required licenses considerably cheaper, but do also maybe offer licenses, which are not needed."
"The price of the NetApp FAS Series is reasonable and it provides value for the money with the feature sets. NetApp FAS Series are competing with Huawei storage which has an office and does aggressive marketing with a discount. However, we found that if our customers do a technology refresh they are happy with the performance of the NetApp FAS Series."
"The pricing of NetApp FAS Series is reasonable for its performance."
"There are products available in market with comparatively lower costs."
"It’s difficult for us to get money, so make sure you get everything in order, because there’s no going back and saying “oh, I missed this or that”, so make sure you plan well and well in advance."
"The process for going to cluster mode is expensive."
"The scalability is pretty good, but it's too expensive."
"It is a one-time license charge for NetApp FAS Series to run and we pay annually for upgrades and support."
