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

"Of all storage technologies I work on, it’s the easiest to learn and one of the most powerful."
"It helps us reduce costs because its data compression saves a lot of capacity we'd otherwise have to have."
"It allows our Windows and Unix teams to have a centralized point to share data between the two."
"This solution is very, very, very, very stable."
"Has rock solid reliability and is easy to use."
"It’s a High Availability environment in which I haven’t had problems."
"Other products lose performance over time, but NetApp OS is speed-optimized."
"It’s a decently mature product that has a lot of documentation and standards and is something to be relied on."
"Very good analytics Very easy to configure."
"I like its storage capacity, quick access to the data, speed, and overall storage management."
"Oracle Sun ZFS Storage Appliance is a very stable and durable product that's very strong and mature."
 

Cons

"When we were going through all the MFA hardening and the anti-ransomware setup, I gave some feedback to our executive. The MFA process for getting that set up on the AFF systems was cumbersome compared to some of our other systems."
"I would like to see less latency and higher IOPS."
"Another issue is the price which, compared to competitors, is quite high."
"It is very unstable. We have a lot of issues with antivirus programs interrupting us from providing services to our customer."
"Needs to improve the adaptive storage quality of service."
"There was a bug when creating new custom roles that automatically gave volume deletion permission, which was a problem, but they finally fixed it."
"The adoption of the cloud in Argentina is very slow. Customers do not move most of their applications to the cloud. Moving applications is a simple task, but the cost is a concern in Argentina. There is an opportunity there for NetApp with Cloud Volumes ONTAP."
"As I see it, there could be more interfaces, more cache, etc., but those challenges are solved by just getting some other model."
"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."

"Uptime. We had some crashes here and there."
 

Pricing and Cost Advice

"It is expensive."
"The NetApp FAS series price is very competitive compared to other solutions on the market it is a good choice."
"The product is on the expensive side."
"I would rate the pricing a seven out of ten, with ten being expensive. We pay a one-time purchase price."
"The only area that could be improved is to lower prices for their All Flash FAS."
"The tool is expensive."
"NetApp FAS Series could be less expensive."
"it’s not an inexpensive solution and it may not be for the cost-sensitive customer."
"The price could be better. We have many competing products now like Huawei and Dell EMC, and these are slightly cheaper."
