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

"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."
"It gives us the performance we need and the reliability we need to make sure that our systems have the uptime that our internal customers demand."
"The solution is highly stable, and NetApp FAS Series is stable in production storage and for the high-density volume services."
"It’s a High Availability environment in which I haven’t had problems."
"Good solution architects and deployment guys are available."
"It is great to see that NetApp is ahead of the game with regard to support for Virtual Volumes – it is also nice to see that the 8.3 release can be installed on older versions of hardware allowing FAS customers, who purchased their systems a number of years ago, to take advantage of Virtual Volumes."
"You can use different protocols at the same time, and monitoring is also very easy in NetApp FAS Series, with a free tool available for monitoring."
"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

"We told him that we need better documentation for customers to understand automation of APIs."
"There should be a separate admin web management for each SVM. We are currently managing all SVMs from a single admin interface, it is a problem."
"It's straightforward in 7-mode, but using cDOT, it's terrible."
"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."
"The current snapshot technology in VMFS is to say the least very poor – best practice is to have no more than 2-3 snapshots in a chain (even though the maximum is 32) and to use no single snapshot for more than 24-72 hours – the reason is simple, storage performance will suffer if you create a snapshot on a VM."
"The user interface could be improved to have better graphics and the performance analyzer could be better."
"The solution can improve on the replication features."
"We'd like to move to a solution that does more beyond just data, like starting to get more to servers and network specialization and data visualization and things like that."
"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

"There are products available in market with comparatively lower costs."
"The scalability is pretty good, but it's too expensive."
"It is a one-time license charge for NetApp FAS Series to run and we pay annually for upgrades and support."
"NetApp FAS Series could be less expensive."
"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 solution’s cost is reasonable."
"it’s not an inexpensive solution and it may not be for the cost-sensitive customer."
"I would rate the pricing a seven out of ten, with ten being expensive. We pay a one-time purchase price."
"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."
