Highly scalable and reliable SAN with fiber channel connectivity but bulky in size and consumes a lot of power

Hot spare disk system to take over the full workload in the event of a failure, at the same performance and service levels. The data is clustered over multiple disks so data read/write access time is very low. Fiber channel connectivity option for high speed data transfer. Single point of management/control. Customized version of Linux OS hence much higher security.

Unified storage has protected critical data and supports smooth admin work for diverse workloads

In my experience with NetApp FAS Series, I found the CLI commands to be very valuable and easy to understand, unlike other storage products. I can use just the show command to see something, and it helps me narrow down issues quickly, which makes CLI easy for me. I use snapshot technology in NetApp FAS Series. The snapshot technology has helped me in data protection. For example, during an upgrade of our ONTAP version at my workplace, it did not reflect properly despite the upgrade being completed. I had a VMware snapshot from another team, and that was helpful for me to retrieve the data right after the failed upgrade. I use snapshots frequently, maintaining a snapshot policy of 28 days which allows me to help users retrieve files they are unable to access. In maintaining data integrity in my operations with RAID DP, I see that it helps me significantly. If two or more disks fail, it gives me time to work on replacements. If only one disk fails without RAID DP, I would lose data and connection, but with RAID DP, I have that time to act without losing or making data unavailable to users. The data management features of Data ONTAP are highly valuable for my organization in terms of data security and compliance. I have not experienced data loss or unavailability as I have SnapMirror, Snapshot, and SnapVault in place. This helped prevent escalations. While I faced some access issues or slowness, severe data loss has not been an issue, and I resolve issues within one to two hours with the data integrity these tools provide.

Quotes from Members

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

Pros

"At last we bought this Celerra NS 40, with 17 TB of space which is giving superb performance."

"The support is very good."

"We have used some solutions like Hitachi, Dell, and EMC, but NetApp has more flexibility and we decided to stay with NetApp."

"Just do it. Chances are the functionality that comes with the ONTAP software will be better than other products at a similar price."

"It has a very good implementation of the Active Directory services, so implementation into a Windows network is easy."

"The FAS series is very stable."

"I would definitely recommend NetApp FAS Series to other users because it's stable and really handy for IT personnel who manage it."

"It saves a lot of time and minimizes downtime, which is important because we're a hospital and we can’t afford much downtime."

"Flash cache is a great product."

Cons

"Very bulky and heavy in weight."

"We would like to have further integration with some backup products. They have some of them already, but there could be more."

"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."

"Its licensing cost can be improved."

"NetApp could improve costs while making the solution more straightforward to use and deploy."

"It could be more flexible in terms of configuration."

"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."

"They should add new features to the product."

"No other area for improvement comes to mind other than its price. Making the price more attractive will help this solution have a bigger market share."

Pricing and Cost Advice

Information not available

"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."

"Low-priced product, but pricing could still be made more attractive."

"The price, compared to competitors, is quite high."

"it’s not an inexpensive solution and it may not be for the cost-sensitive customer."

"When we need to implement a less expensive solution we use Huawei. NetApp FAS Series is a little bit expensive compared to the average of the market."

"The tool is expensive."

"The scalability is pretty good, but it's too expensive."

"It is expensive."
