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

"I would rate this solution a ten because of what NetApp provides us from a quality layout. The partnership that they provide us and their assistance is very important and the work that they communicate with us on a regular basis is outstanding."

"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."

"It has been very stable. We haven't had a significant outage."

"Data protection is essential. When we had power-related issues and the storage box went off abruptly, we were able to recover without much challenge or corrupted data."

"Technical support is good. NetApp's solution engineers are good at architecting designs which are standard, but also future thinking. I've only opened a few tickets, and they've answered my questions each time. NetApp takes less than four hours to respond."

"It most valuable feature is its stability. A product has to be stable."

"The best features of NetApp ONTAP include its good UI."

"The stability of our ONTAP system has been awesome over the last four to five years, particularly with the software. The controls have been excellent as well. We recently went through a view of all of our systems and found a number of them had been up, over three years without any sort of reboots or downtime. We have been very happy with the stability of the systems."

More NetApp ONTAP pros

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

"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."

"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."

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

"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."

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

"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."

More QoreStor pros

Cons

"I could see the GUI being a little bit more refined, the presentation layer being a little stronger, a little less sluggish."

"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."

"It doesn't scale horizontally since there are a limited number of shelves."

"We would like to have additional cloud integration and the ability to Snapshot directly to Amazon. This would help us reduce costs, provide us additional disaster recovery, and give us a site that's not owned by us."

"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."

"In Africa, especially in West Africa, NetApp doesn't chat with their customers. Therefore, we always have to go through the local partners or vendors."

"It takes them a few seconds to do a failover. I hope they can reduce this to milliseconds or at least drive it down to less than two seconds. Some of their competitors are already doing this."

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

More NetApp ONTAP cons

"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."

"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."

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

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

"The setup of the software is definitely not the easiest thing. I worked a lot with Quest engineers, especially in the early days when we were first testing it and trying it out. I actually had some of the developers working with us at one point because they were going through these point releases, and I was having trouble getting it to work in this S3-compatible situation. We got it all working eventually, but setup is definitely not the easiest thing in the world."

"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

"They could reduce the price."

"The data compression and deduplication have kept us from buying more disks these past three years."

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

"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."

"Depending on the licensing you choose the price varies. For our company and our needs, the cost is very fair."

"Additional costs exist if you want a license for a feature like SnapMirror."

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

"ONTAP has helped our organization reduce its overall cost of storage (somewhere in the high millions)."

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."
