Srikanth Purushothaman - PeerSpot reviewer
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.

A stable unified storage system that enables quick access to data
The main thing Oracle can improve is the cost. It would be better if Oracle opened up the system to enable integration with other vendors. Whether it's the database, application server, or storage appliance, they should make it easy to integrate them. They need to open up more to ensure that it can work in any environment and IT ecosystem.

Quotes from Members

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

Pros

"We can manage our applications from a single dashboard."
"The solution's most valuable feature is its absolute reliability."
"NetApp's cloud-based PaaS has been a massive help for unstructured data."
"The solution is very stable and reliable"
"It gives us the performance we need and the reliability we need to make sure that our systems have the uptime that our internal customers demand."
"Has rock solid reliability and is easy to use."
"End-users like that they can rely on the Snapshot technology so they can do their restores themselves."
"Other products lose performance over time, but NetApp OS is speed-optimized."
"I like its storage capacity, quick access to the data, speed, and overall storage management."
 

Cons

"The product must support more drives."
"The adoption of flash by NetApp has also been lagging behind the trendsetters, like TMS, Nimble, and others."
"It's not a cheap system. It is very expensive. The pricing has been ridiculous every time that we had to renew the support."
"Currently, the newest release is not HCI friendly."
"Needs more SAN support."
"Needs to improve the adaptive storage quality of service."
"The high cost of the product is an area of concern, so from an improvement perspective, the tool needs to be made cheaper."
"We have some experience with older equipment end-of-life. For example, when warranty support stops or updates stop – it can be frustrating. Not all clients can buy a new filer every year or two, and NetApp ending support a bit quickly can be a concern."
"The main thing Oracle can improve is the cost. It would be better if Oracle opened up the system to enable integration with other vendors. Whether it's the database, application server, or storage appliance, they should make it easy to integrate them. They need to open up more to ensure that it can work in any environment and IT ecosystem."
 

Pricing and Cost Advice

"It is a moderately low-priced platform."
"In general, I find NetApp to be very expensive. That's the main issue I have with them. So it's a drawback in terms of pricing."
"The process for going to cluster mode is expensive."
"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."
"We are on a perpetual license."
"The NetApp FAS series price is very competitive compared to other solutions on the market it is a good choice."
"The product's pricing is reasonable."
"I would rate the pricing a seven out of ten, with ten being expensive. We pay a one-time purchase price."
"The price could be better. We have many competing products now like Huawei and Dell EMC, and these are slightly cheaper."
