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.

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

"NetApp FAS has provided an HA environment that has improved the up time of our entire infrastructure."
"It has been many years since we have had an outage due to storage because of FAS."
"The product is flexible."
"In the past, I used, and still work with, solutions like Fujitsu and Hitachi, but when I have an opportunity to work with a NetApp solution, I don't want to go back."
"The solution is very stable and reliable"
"The most valuable feature for us is the combining of HA and SnapMirror."
"Using the built-in Snapshots and SnapMirror technology, we were able to have better working data protection locally and off-site."
"Of all storage technologies I work on, it’s the easiest to learn and one of the most powerful."
"Oracle Sun ZFS Storage Appliance is a very stable and durable product that's very strong and mature."
"Very good analytics Very easy to configure."
"I like its storage capacity, quick access to the data, speed, and overall storage management."
 

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."
"The biggest issue we face is parts delivery. There's no local warehouse in Myanmar, so if a customer encounters a technical problem like an IMEI issue, they have to wait a long time for replacement parts."
"Needs more SAN support."
"The product must support more drives."
"The solution can improve on the replication features."
"We're supposed to have used NetApp FAS Series for replication, but then one of the nodes failed, and then it's taken us some time to bring it up."
"Replication should ideally be part of the ONTAP base bundle."
"They need to improve the go-to-market for all-flash and converged infrastructure."
"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."
"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.

Pricing and Cost Advice

"I would rate the pricing a seven out of ten, with ten being expensive. We pay a one-time purchase price."
"There are products available in market with comparatively lower costs."
"The tool is expensive."
"We purchased it for four years, and it wasn't expensive. It was reasonable. Every company has a different agreement with NetApp. We got everything we wanted with all the bells and whistles and all the features and functionalities."
"The pricing of NetApp FAS Series is not cheap, but in comparison to other vendors, NetApp FAS Series is affordable because they also have deduplication, compression, and inline compression. They focus on storage only, which is really good; it works."
"NetApp FAS Series could be less expensive."
"NetApp FAS Series is a reasonably high-priced solution, partially because we select the configuration that duplicates the entire system."
"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."
