BK
Senior Storage Engineer at Shell
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-efficient, highly scalable, and installable on different types of hardware
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. We are pretty lenient as we do a lot of IT support ourselves. We are not very hard on support organizations, but when a customer has a support issue, it would be easier if the support processes were a little bit more automated. It would be beneficial to have an easier way to upload diagnostic dump files. They can make it easy for the customer to collect the diagnostic data. There can be some kind of monitoring solutions to alert users to issues with the appliance or software, making it easy for customers to monitor their systems in the field. This is especially critical because it stores customers' backups, and a failure can have significant business impacts. If a customer does not have the backups and has a disaster, they can be out of business, so monitoring is key.

Quotes from Members

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

Pros

"Overall, for us, it's the stability, it has a solid infrastructure. It's easy to use, easy to rack and configure and start utilizing really quickly. It's been very stable, it works great, and it does everything we would want it to do."
"ONTAP's technical support is awesome and always ready to help."
"The impact of NetApp ONTAP technology on the way I do business is significant because, unlike traditional file systems, it has different features that enable it to operate as an operating system, providing a broader scope of control and allowing different types of network storage, whether it's file shares such as SMB, NFS, or iSCSI block for low-latency use cases."
"Deduplication, data protection, and NetApp block are some of the valuable features of the product."
"From a service level perspective, we can restore it from a snapshot in a very short period of time, whereas traditional backups from some of our larger databases could take many hours to recover."
"The most valuable feature is the ability to restore and backup our virtualized servers on demand."
"The most valuable feature is the very high IOPS rating which you can achieve with it."
"You can scale the product up or out."
"I would rate QoreStor a ten out of ten for what it offers for the price."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"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."
"Overall, it simplifies the management of backup and gives me a more secure feeling that my data is going to be available if I need to retrieve it."
"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."
"We need revisions and safe backup so that it could be held up in court, but deduplication and compression are the main features why we have Quest QoreStor. That's where it really shines. I use ZFS and XFS at home, and Quest QoreStor is even better."
"QoreStor has helped us to reduce our backup storage requirements on-premises, and we've been using the same devices for quite a while, so it lets us keep using them as opposed to having to rip out all that hardware and create a new on-prem solution."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
 

Cons

"We're at 9.3 so when we go to 9.5 we would like the synchronous SnapMirror because our users would like that, especially the ones that do the conveyor belt of data. We'd like that."
"They could lower prices so my management doesn't complain about cost"
"The setup can be a bit complex, depending on the environment."
"I would like the ability to perform backups in the cloud. That way you don't have to worry about building the data center. Everything's already in the cloud."
"The additional features I would like to see in ONTAP, and NetApp in general would probably be the single pane of glass software."
"With our current use case, we will need something faster. E.g., if you have a huge scale, having SSD-based backup is better."
"The first year was not a great time, between a lot of email exchanges, a lot of escalations, etc."
"However, if the integration with legacy applications was simpler, it would be great."
"In terms of improvement, we would like to have an Air Gap feature to prevent a virus from attaching to something."
"The setup of the software is definitely not the easiest thing in the world."
"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."
"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"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."
"They need to increase their maximum capacity."
"The installation could use improvement. The initial installation was a little touchy and it's not really user-installable."
 

Pricing and Cost Advice

"We have a wholesale contract with NetApp. We also have NetApp ONTAP On-Demand activation for certain things. We also have some preferential pricing for licenses. The licensing that I see here doesn't apply to other clients in the field. NetApp is expensive, but so are the competitors, making it hard to ascertain precise retail value. However, based on my perspective, NetApp pricing appears competitive."
"Recently, we have seen ROI."
"I rate NetApp ONTAP's pricing a seven out of ten."
"We save a lot because of the deduplication and compression."
"Because of its manageability, we have fewer people managing it."
"Depending on the licensing you choose the price varies. For our company and our needs, the cost is very fair."
"The product is a bit expensive."
"NetApp provided the features required within our cost limit."
"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
"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."
"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."
