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 virtual deduplication backup appliance that protects physical and virtual data across remote sites, the datacenter and cloud deployments
Given its ease of use and management, I believe there are no specific caveats that users need to be aware of during the setup of DXRIS for backups. The process was straightforward, and I did not encounter any challenges or issues. As for a rating on a scale of one to ten, with one being the worst and ten being the best, I would rate the Quantum DXI Series a nine. My deduction is primarily influenced by personal preferences, particularly regarding the user interface and it is a highly commendable system, I would rate it a solid nine out of ten.

Quotes from Members

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

Pros

"The most valuable features are compression and dedupe."
"Good for NAS and unified solutions."
"Adaptive balancing is a valuable feature."
"It's a stable product. No issues there."
"I would definitely recommend NetApp FAS Series to other users because it's stable and really handy for IT personnel who manage it."
"The solution's most valuable feature is its absolute reliability."
"Other products lose performance over time, but NetApp OS is speed-optimized."
"I have found all the features useful in NetApp FAS Series."
"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

"NetApp FAS Series should introduce an FTP application for the broadcast and post-production market."
"It's not a cheap system. It is very expensive. The pricing has been ridiculous every time that we had to renew the support."
"NetApp FAS Series should improve its price, which is expensive."
"I’ve found that I use command line more often than I thought needed. Some things should be done in the GUI, and command-line switches can be overwhelming and take up a lot of time."
"The solution could do more than just data."
"The high cost of the product is an area of concern, so from an improvement perspective, the tool needs to be made cheaper."
"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 should include an audit log feature."
"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

"It is expensive."
"The tool is expensive."
"Most storage vendors also have software, or licensing bundles, which may offer the required licenses considerably cheaper, but do also maybe offer licenses, which are not needed."
"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."
"It is a one-time license charge for NetApp FAS Series to run and we pay annually for upgrades and support."
"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."
"In general, I find NetApp to be very expensive. That's the main issue I have with them. So it's a drawback in terms of pricing."
"Low-priced product, but pricing could still be made more attractive."
"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."
