DIRECTOR at Vellore Online Systems
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.

Expert Backup at a tech services company with 201-500 employees
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

"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."
"The most valuable feature of the NetApp FAS Series is its stability."
"The NetApp FAS Series has helped simplify our infrastructure."
"One important feature for customers is its ease of use and continuity, enabling seamless usage across on-premise and cloud environments."
"It changed the way we do Disaster Recovery (DR) around NetApp replication."
"NetApp FAS is highly stable and reliable, especially under a heavy load. That is what I like most about the NetApp."
"I sleep well at night because of its redundancy."
"It has been pretty stable, and when we have issues, the support has been great as well."
"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 solution can improve on the replication features."
"Unified Monitoring v6.2 loses a bunch of functionality that previous versions had."
"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 user interface could be improved to have better graphics and the performance analyzer could be better."
"If our customer needs a high-performance storage solution then we don't recommend this product."
"It's straightforward in 7-mode, but using cDOT, it's terrible."
"We'd like to get more access to level-two engineers. Sometimes its been a difficult time explaining the problem to level-one people."
"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

"NetApp FAS Series could be less expensive."
"The scalability is pretty good, but it's too expensive."
"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."
"The only area that could be improved is to lower prices for their All Flash FAS."
"If we want a ransomware solution with the product or other extended features, we need to pay an extra cost."
"NetApp FAS Series' pricing is competitive."
"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 NetApp FAS series price is very competitive compared to other solutions on the market it is a good choice."
"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."
