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

"Good bang for the buck."
"Other products lose performance over time, but NetApp OS is speed-optimized."
"I love those innovative healthcare data solutions that let me securely manage vast amounts of patient data (32.9 PB), use and share it enterprise-wide, and gain efficiency of scale through cloud solutions and virtualization."
"Adaptive balancing is a valuable feature."
"Go with NetApp; I haven't had a problem with it."
"Cost effective storage for all performance levels (including all-flash) Integrated snapshot and backup capability Many protocols Good service"
"Reliability performance level, great history with it, and over the last two and a half years, it's been better than others."
"You really can't go wrong with NetApp products, They perform well, are rock solid, offer good space saving technologies, and the support is above par."
"Very good analytics Very easy to configure."
"Oracle Sun ZFS Storage Appliance is a very stable and durable product that's very strong and mature."
"I like its storage capacity, quick access to the data, speed, and overall storage management."
 

Cons

"It's hard to find in-person training that fits our schedule in our area. They offer a lot of online training, but we need somewhere to go because we can't really get away from the office."
"It lacks automatic tiering, When you use data, some of it goes cold. It is not hot data, so the system should automatically move that data to the SATA, while the hot data is kept on tier-one, the SaaS or SSD drives."
"The solution's configuration is not flexible."
"Installation of the additional switches and ETP could be improved."
"There is a real danger that your new storage array becomes obsolete shortly after purchase."
"One of the issues that we have had with NetApp in upgrading over the years is that migrating data from one system to another is one-way only."
"It's not a cheap system. It is very expensive. The pricing has been ridiculous every time that we had to renew the support."
"We would like to have further integration with some backup products. They have some of them already, but there could be more."
"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

"The tool is expensive."
"Low-priced product, but pricing could still be made more attractive."
"I don't recall the price, but in general, pricing can always be better."
"NetApp FAS Series is a reasonably high-priced solution, partially because we select the configuration that duplicates the entire system."
"The solution is more expensive than other vendors."
"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."
"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 price could be better. We have many competing products now like Huawei and Dell EMC, and these are slightly cheaper."
