Data management and availability improve operations, but cost and support need attention

For snapshots, there should be something similar to a recycle bin. When someone mistakenly deletes a snapshot, it should be stored for about two days before disappearing from the system. Regarding storage optimization, when purchasing a 10 terabyte disk, after formatting, you can only use approximately 8 terabytes. They should improve this so users can utilize 90% instead of 80% of the disk space. The support response needs improvement, especially for P1 cases. When critical cases are raised, they should ensure they call the customer and follow up properly. Comparing NetApp ONTAP to other solutions such as EMC, the cost of contract renewals and warranties is relatively expensive. They should extend their renewal window beyond the current six months to one year options. A longer warranty period of two years for new systems, controllers, or filers would be beneficial. Overall, they should reduce subscription costs for businesses.

Cost savings and efficient data management improve operations but support quality varies

The importance of support is significant to me. I was working for a service provider, and all of our customers had a Quest or warning. Sometimes the support really underperforms. I always had to get it escalated or ask for someone specifically because those other people would just read knowledge-based articles that I had already done myself. Quest QoreStor does not work with any backup software, server, or storage hardware. It has the hardware compatibility list, and you need a specific number of IOPS, so it needs to run on decent hardware at least to have enough input-output operations. Otherwise, the setup result will be canceled. I'm not too sure if there are still physical appliances, but when I first started, we had some customers with a physical Quest QoreStor appliance, and it would only run on certain hardware. It doesn't work with every backup program. For example, Veritas Backup Exec is incompatible, but Veeam is compatible, and V Ranger is compatible as well. I didn't even know that Quest QoreStor has any static AI and behavioral AI technologies.

Quotes from Members

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

Pros

"My experience with NetApp is its very easy to learn and intuitive. I can figure out just about everything."

"The product is good at deduplication. Also, the new automation feature is good, as it saves us a lot of time."

"Its usability, scalability, and dependability are very good."

"They always have new solutions for their customers. They also have good integration with other partners like Microsoft, VMware, and Oracle."

"The MFS report is the best feature for us."

"The solution is very easy to configure."

"ONTAP has improved my organization by lowering budget costs. Deduplication, compression, compaction, SnapMirror, SnapWall, the transaction happens from one to the other. It's serving our needs just as expected."

"It is able to store a lot of data, and we can manage it with fewer people."

More NetApp ONTAP pros

"Deduplication is the most valuable feature. It saves us a lot of space. When we back up 100 terabytes of data, after dedupe, it only uses maybe five to six terabytes for the disk space in QoreStor."

"Quest QoreStor is very stable compared to our previous solution."

"Quest QoreStor definitely saved us money."

"The extreme compression of data is a big thing for us. We were looking for an online backup solution, and QoreStor is very good in terms of data compression. It helps us minimize the required storage in the Blob Storage environment."

"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."

"The features we use for the data deduplication are nice because we're able to back up a much larger amount of data, yet it doesn't necessarily take up that much data on the devices."

"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."

"This software solution can be installed on many different types of hardware, which makes it very flexible. We can run it on virtual machines or virtual servers, providing convenience for solutions of varying sizes, from small to large."

More QoreStor pros

Cons

"The older UI is not ideal."

"I would like to see more S3 integration with other vendors, objects, or instruments."

"It is not as good as we need from a performance perspective. At the moment, we are always running out of CPU on the controllers, even the high-end solutions."

"The config could be a little easier. It's not entirely difficult, but it could be a somewhat easier. I have seen other vendors make it easier."

"The setup can be a bit complex, depending on the environment."

"The lack of an API is a big thing for us that needs to be improved. It needs proper API support."

"I would like to see FlexGroup volumes come to parity in terms of software features with Flex volumes. It seems like FlexGroup volumes have massive scalability, but their features set is not the same as Flex volumes, so we are currently unable to use it."

"Because most of us were new to the product, the initial setup was a bit cumbersome. Once we were trained, it was fine."

More NetApp ONTAP cons

"The ransomware protection of QoreStor could use improvement."

"The importance of support is significant to me. I was working for a service provider, and all of our customers had a Quest or warning. Sometimes the support really underperforms."

"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."

"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."

"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."

"They could improve on support a little bit. We have not had to engage their support much, but when we do have issues, it can take longer to get things resolved."

"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."

"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial. After everything is set up and configured, there should be a way to export the configuration. In case something happens to the QoreStor server, and we need to reinstall and configure everything, being able to import the configuration would be helpful. This feature does not currently exist."

More QoreStor cons

Pricing and Cost Advice

"Our pricing with discounts is reasonable, but it may vary for others."

"We save a lot because of the deduplication and compression."

"Our cost per IOP is three to four dollars, but we have a hybrid solution. Therefore, we have SSD and spinning disk running together."

"I rate NetApp ONTAP's pricing a seven out of ten."

"When you purchase NetApp for the first time they will provide you with the standard license, or a premium license, and even a standard bundle solution license."

"NetApp ONTAP is a pricey product, but you pay for what you get. I rate NetApp ONTAP a five out of ten for its pricing."

"The licensing prices are really high."

"The solution has helped us reduce the overall cost of storage by doing an OPEX agreement with NetApp, we are paying based on utilization. Instead of fronting 30 petabytes worth of storage, we are paying for what we're using."

More NetApp ONTAP pricing and cost advice

"Quest QoreStor's pricing is affordable. We evaluated Veeam, a well-known company for backup solutions, but found their pricing to be quite high. Veeam's price was almost double. For us, Quest QoreStor is very affordable."

"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."

"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."

"The pricing is good. It is competitive for a managed services provider. I like the ability to pay by the terabyte, allowing for an incremental cost that we and our customers can afford, so the solution grows with the customer."
