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

"Snapshot and SnapMirror technologies make it easier to replicate data to disaster recovery scenarios."

"SnapMirror is a good solution, because we can take our production data and replicate it over to our DR data center with minimal administrative effort, which is huge."

"It's more intuitive to use as they are moving away from command line into more graphical interfaces, which are somewhat easier to use."

"The most valuable feature is the very high IOPS rating which you can achieve with it."

"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."

"NetApp ONTAP has absolutely been a game changer for our organization. We support and use different storage services, but this is the first time we have a service and storage that supports multiple protocols, such as SMB, NFS."

"Our organization is short-staffed, and ONTAP's ease of storage management is well-suited to our small team."

"Scalability is awesome with a cluster node, not only can you scale up, but you can also scale out."

More NetApp ONTAP pros

"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."

"Quest QoreStor definitely saved us money."

"QoreStor has helped us to reduce our backup storage requirements on-premises. We've been using the same devices for quite a while, and so it lets us keep using them as opposed to having to rip out all that hardware and create a new on-prem solution. The advantage here is even if we had to retire the hardware tomorrow, the QoreStor part doesn't change. We just have to have additional hardware and put the solution back on whatever hardware we pick and it'll do the same thing."

"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."

"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."

"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."

"I would rate QoreStor a ten out of ten for what it offers for the price."

More QoreStor pros

Cons

"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 vendor diagnostics, which allows for movement from one vendor to another vendor using the application technology that is available. It should be able to talk to any vendor, not just NetApp to NetApp. We should be able to replicate the data, so the next feature should not be vendor specific."

"The only thing I don't like is that firmware upgrades require downtime. It would be beneficial if we could do upgrades without as much downtime."

"I would like to have deduplication and SSD features in the product."

"One of the challenges we have is the ability to tag data with ownership for internal billing and chargeback. We have to utilize some third-party tools for that. It would be good if they were integrated with NetApp ONTAP. Everything else is pretty good."

"With NetApp ONTAP, the technology is all there, but its management process needs some simplification."

"I would like to see more integration into the cloud, as we are pushing to do more cloud-based compute. It is just easier to get the storage and everything synced up there and move to the cloud. We want NetApp to keep down the cloud integration path. It still needs some improvement. Overall, there needs to be more cloud integration in all NetApp products."

"I believe that the next release should be a bit cheaper."

More NetApp ONTAP cons

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

"In terms of improvement, we would like to have an Air Gap feature to prevent a virus from attaching to something. So that when we don't do a backup, we want the QoreStor to stay offline. It would be a nice feature to have."

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

"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."

"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."

"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."

"The installation could use improvement. The initial installation was a little touchy and it's not really user-installable. You have to have a connection to support to install."

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

More QoreStor cons

Pricing and Cost Advice

"It's not an all inclusive model. You have the option to purchase modules to make the entire ecosystem coherent. I would like the option to pay one price and get everything all inclusive, like OnCommand."

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

"They could reduce the price."

"NetApp is streamlined, reducing costs."

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

"There could be improvements, its proprietary software so it can be pricey."

"The licensing prices are really high."

"There are specific workloads where some vendors provide better value, but in general, NetApp has done a far better on price than other vendors."

More NetApp ONTAP pricing and cost advice

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

"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."

"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."
