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 scalable solution with Veeam and Vertias alliance
I am impressed with the tool's technical alliance with Veeam and Veritas.  The product needs to improve performance while scaling out. It also needs to improve stability.  I have been using the product since seven years.  I would rate the product's stability a nine out of ten. I would rate the…

Quotes from Members

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

Pros

"The file sharing feature is most valuable."
"The input and output per second performance are satisfactory."
"The strong point is that our clients like this are RadLV (Radiology Low-Value). They also use SnapMirror and MetroCluster."
"I would definitely recommend NetApp FAS Series to other users because it's stable and really handy for IT personnel who manage it."
"At the moment, we use NetApp SnapMirror to replicate data to another filer at an offsite location for backup. So, I like this feature."
"The support is very good."
"Most valuable features are its ease of use, robust Snapshot functionality, and that you can use it in two datacenters with SnapMirror-ing."
"Other products lose performance over time, but NetApp OS is speed-optimized."
"I am impressed with the tool's technical alliance with Veeam and Veritas."
"While the challenges posed by the difficulties were significant, they prompted the replacement of problematic components, resulting in the resolution of issues. Importantly, there were no substantial ongoing concerns. Regarding the overall performance, it has been consistently excellent."
 

Cons

"The user interface could be improved."
"Replication should ideally be part of the ONTAP base bundle."
"It was not possible to have a custom user inside ONTAP without the delete permission to delete the volume. We wanted others to be able to create a SnapMirror and volume, but have no volume deletion permission. In the newest version, it seems to already be in place, but there was a bug enabling this one in older versions 9.11, 9.10, or earlier."
"The product should improve its user experience."
"There are some technical limitations, but it would be great to have in-line deduplication and in-line compression for the FAS series as well."
"The plan is to go with all SSDs and use MDM, rather than sticking with traditional disk drives. The goal is to have all SSDs for better maintenance speed, which is essential for applications that need to work."
"NetApp needs to put its OS on a microchip rather than on disks."
"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 product needs to improve performance while scaling out. It also needs to improve stability."
"Perhaps the most notable area for enhancement lies in the web interface for management. The current limitations in LDAP editing capabilities are not addressed in the UI, and I haven't observed any recent updates. It's possible that the new version of the DXI service incorporates improvements in the GUI, but I cannot confirm. While there is room for improvement in the current GUI, it remains a relatively minor issue. Overall, the system is comprehensive, covering aspects such as reports on latency and networking, leaving little room for additional enhancements in those areas."
 

Pricing and Cost Advice

"I don't recall the price, but in general, pricing can always be better."
"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."
"We have considered upgrading to an All-Flash solution but when we evaluated the cost-benefit we discovered that we don't have enough money to invest in it. To maintain the same technology with All-Flash would be too expensive for us."
"The NetApp FAS series price is very competitive compared to other solutions on the market it is a good choice."
"The process for going to cluster mode 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 solution is more expensive than other vendors."
"The scalability is pretty good, but it's too expensive."
"I do not oversee this aspect, as pricing is contingent on factors such as volume, technical specifications, and the desired features. Consequently, I lack information on the pricing details and structure."
