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

"Stability and performance have been great."

"The product is reliable. We always want to have access to the files, and the system has to be up 99.9 percent of the time."

"Previously we didn't have DR, but ever since we purchased the NetApp server, we are able to use Snap Mirror and then create DR scenarios, so that's been a huge benefit. This solution has helped reduce the overall cost of storage space in our organization by allowing us to use one data center, instead of two, and then allowing us to replicate the data; so that saves us money to buy more storage. We have been able to save space by using this solution."

"We saw the benefits of NetApp ONTAP almost immediately; snapshots are amazing, the auto-grow on the volumes and SnapMirror are also notable features, and there are so many things that make it a good product."

"The moment you start using it is when the magic happens."

"The whole point of our project and the team I lead is that we wanted to be able to move data from a ship back to shore. With ONTAP, we are able to do that extremely fast, especially based on the way we were doing it before."

"Otherwise, they are very, very good in all other areas; their hardware, software, their support, etc., are all good."

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

More NetApp ONTAP pros

"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."

"Not having to be onsite to swap tapes on a daily, weekly, or monthly basis, alone, has really paid for its usage through the savings in time."

"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."

"Quest QoreStor definitely saved us money."

"The dedupe and compression are pretty extreme. On disk, we're getting dedupe rates of up to 65 percent of data and compression of 34 percent. When you go to the cloud, it's more like 76 percent for dedupe and almost 50 percent for compression."

"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."

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

"Since we started to resell QoreStor, we have been using it internally; it's better than other backup solutions we have used or evaluated."

More QoreStor pros

Cons

"One of the things that we were looking at being able to do a FlexGroup NFSv4. Right now, 9.4 goes up to NFSv3, but if we could get the NFSv4 solution on a 9.4, or a future release, that would be awesome."

"Some of their products have been really good for us, on certain versions. We've run into a bunch of verts, though. That's NetApp's word for their bugs. Stability has been the main complaint that I've had with the product. Because it's so feature-rich and has so much software related to it, it does come with a decent amount of bugs so we do a lot of upgrades to patch bugs."

"I'm waiting for end-to-end NVMe."

"They could focus on making it more user-friendly. Currently, many users need a certain level of NetApp knowledge to operate it effectively, often relying on command-line interfaces that demand IT or technology skills. While there is a GUI available through Systems Manager, a lot of management still occurs at the command line, so enhancing the GUI for better usability could be a key focus area."

"The older UI is not ideal."

"One area where they could improve NetApp ONTAP is their ability to migrate to and from different enterprise storage."

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

"I would like to see more evolution towards the cloud."

More NetApp ONTAP cons

"The setup of the software is definitely not the easiest thing in the world."

"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."

"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."

"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 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."

"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."

"In terms of improvement, we would like to have an Air Gap feature to prevent a virus from attaching to something."

"The ransomware protection of QoreStor could use improvement."

More QoreStor cons

Pricing and Cost Advice

"It has been cost-efficient. Compared to our legacy Dell infrastructure, we have realized cost savings. It is good."

"With other vendors, we need to buy a separate license for a third-party storage, but with NetApp, you don't need to buy a license, as it will come up with the storage."

"NetApp provided the features required within our cost limit."

"It helps us save money using compression and deduplication."

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

"Because of the dedupe technologies and Data ONTAP servers, we have saved 20% on hardware. This is a lot of money for us."

"The price could be a little bit cheaper, but you get what you pay for."

"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."

More NetApp ONTAP pricing and cost advice

"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."

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

"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."
